Does Insulation Work in the Summer?

Insulation in Summer

For most of insulation is something that keeps us warm in the winter and is less of an issue in the summer months. Sweltering hot summers aren’t something that has been a major issue, but when the temperatures do rise, how does it feel in your house?

Hot sticky nights that mean you have to throw the windows wide open, let the hot air out and the cool air in, along with a jungle’s worth of moths, daddy long legs and spiders?

The purpose of insulation is to stop or reduce the movement of heat between two places of varying temperature. So in warm weather if your insulation is doing its job it should keep your building cooler.If you have established a thermal cocoon for your home you will have a created a barrier that will prevent h
ot air getting into your building on a really hot day. This works as the same way in which you lose heat in the winter. The same insulation that retains heat in winter should deflect away the heat from the sun in the summer months.

If your insulation isn’t up to scratch you will notice that the room that is really cold in winter is the same room that is very warm in the summer.

The importance of good insulation is that it doesn’t just save you heating costs and energy in the winter but it also keeps the home cool in the summer.

If you are thinking of having an insulation upgrade, the summer is a good time to proceed. Why? Well because during the summer months the house has hopefully had time to dry out somewhat, the walls will have less moisture. The other practical reason is that decent summer weather makes it easier for a contractor to install the insulation.

Understanding Moisture Movement

Moisture movement, especially in porous walls, has to be taken into account when planning your internal wall insulation upgrade.

Adding insulation to the inside of a solid wall reduces heat loss and has an effect on its natural ability to dry.

Based on the type of wall you have you need to decide what system best suits your wall type.

We have three options: Vapour Open; Vapour Closed; or Vapour Closed with Reverse Diffusion Membrane. We can advise you to ensure you make the right decision.

Floored by The Wrong Advice?

Insulating Floors

The conventional wisdom around insulating existing floors in your home is that it is problematic. Full Stop. Why? Well, because without going ahead and lifting a solid floor, we are often advised that it is difficult to introduce any permanent thermal insulation. Once a floor is in place, it is like an immovable object. However there are floor insulation solutions available.

Floor Insulation from Enviroform InsulationTraditionally solid floors will often feel cold and a little damp, as tiles, bricks or flags could be laid directly in contact with the ground beneath. Concrete floors present another set of problems. Even if the floor includes a damp proof membrane, it may not be well insulated. And where there is a DPM and no sign of moisture, the advice is typically that you can go ahead and lay a wooden floor or some sort of flooring with a thermal underlay.

A lack of awareness of the options available means that householders often settle for a solution that is far from ideal. And they continue to lose heat through their floor.

Heat Loss Through Floors

When you think about heat loss, most people straight away look at the usual subjects. Draughty windows and doors, but it is a fact that heat lost through a solid floor can cost you money and drastically reduce the energy efficiency of your home.

Heat loss through the floor is particularly a problem in older homes. Many older buildings will have ground floors made from either uninsulated or poorly insulated solid concrete. It relates to the original construction of the building when builders were less aware of the potential for heat loss.

It wasn’t until the 1930s that concrete floors became relatively common. Prior to that ground floors tended to be basic slabs or tiles laid onto the ground. The Victorians used suspected timbers in most rooms, and for upper stories, floors featured timber joists. Modern suspended concrete floors didn’t appear until the 1990s. Also, main older homes had their floors dug up and replaced with concrete.

The problem that you face if you have a concrete floor is that excavating the surface isn’t an option for obvious practical reasons. The other problem is that a layer of insulation that is too deep will cause problems with doors closing and the level of adjacent floors.

ETherm Flooring from Enviroform

To address these practical problems at Enviroform Solutions we developed the E-Therm products, which are the highest performing retrofit flooring insulation solution available on the market. It is specifically designed for solid floors where space is at a premium, and excavating is not an option.

E-Therm Slim

E-Therm Slim panels consists of a 2x6mm ship lapped calcium silicate boards bonded to foiled faced PIR insulation. No special tools or precautions are required when fitting the panels and can be cut to the required shapes and size.

E-Therm Ultra

E-Therm Ultra panel consists of a 3mm high impact layer bonded to 10mm Aerogel insulation layers and then wrapped in a highly durable and robust vapour control layer. No special tools or precautions are required when fitting the panels and can be cut to the required shapes and size.

Domestic furniture can placed on top of the E-Therm Ultra which is compatible with most floor finishes and under-floor heating systems. It is supplied in a pre-formed panel to allow for fast installation.

If you have a floor that you think needs looking at, contact Enviroform Solutions now. We can advice you on the best approach and the solution that fits your floor.

Product Focus: Spaceloft Aerogel for Steel Posts and Window Lintels

Spaceloft Aerogel Insulating steel posts and window LintelsInsulating Steel Posts and Window Lintels

Insulating steel posts and lintels. It is a simple but valuable detail in ensuring the integrity of your home insulation. Time and again we see examples where clients go to the extreme of installing ultra efficient windows. But they neglect the details. The details in this case are Steel Posts and Window Lintels.

Neglecting insulation in posts and window lintels is a very common issue in new houses where steel supports are used between frames in bay windows.

Abandon Heat all Who Ignore Insulation

If the steel lintel isn’t insulated, you are effectively leaving a window ajar in the thermal cocooning of your property. By not insulating the steel post properly, you will have created a cold bridge. Over time that will reveal itself in the form of mould and damp patches.

Wrapping a steel support in 10mm foiled Spaceloft Aerogel will serve to insulate this section and eliminate the cold bridge. This will help prevent mould growth in the years ahead.

Window post and doorframe insulation is often selected even after high performance heat efficient windows are installed.

Insulating steel posts with Spaceloft Aerogel insulation can be a relatively straightforward solution. Creating an unbroken insulation layer ensure the integrity of your building.

Installation Guide

  • Cut foiled Spaceloft Aerogel to size. Make sure two pieces are wider by 20mm ensure full coverage.
  • Using the spray glue provided, spray the steel and then the Spaceloft Aerogel. Wait until tacky (1-2min) then place Spaceloft Aerogel onto steel.
  • Using high grab air tight tape, cover all horizontal, vertical and corner joints, making sure that that are no gaps in the Spaceloft Aerogel blanket layer.
  • New window or doors can be butted up against the Spaceloft Aerogel and fixed as recommended.

About Spaceloft Aerogel

If you want to reduce the heat loss from your property, maintain the historical identity and integrity of your building and enhance the safety, warmth and comfort of the occupants then you cannot look beyond Spaceloft Aerogel.

Using Spaceloft Aerogel as your insulation solution will Boost R values and address thermal bridges. Our products are carefully thought out to place your hoe within a warm and safe thermal cocoon.

Bonfield Review: An Insulation Roadmap?

The Bonfield Review was published on 16 December. It was a long awaited ‘State of the Nation’ review of home energy efficiency and insulation. Unsurprisingly it endorsed what many players in the industry have been saying for many years.

The Review’s main focus was:

  • Consumer advice and protection

What supports consumers’ decisions ahead of the installation, and what assistance is available when things go wrong?

  • Standards framework

What ensures that the right products are fitted to the right properties in the right way during the installation?

  • Monitoring and enforcement

What ensures that poor quality work is dealt with effectively, and do arrangements for audit, compliance checking and sanctions provide sufficient assurance of this?

Building Specific Solutions

Since we started our mantra has been an emphasis on building specific solutions. One size does not fit all. Each building has its own character, style and like people, each building is affected by external factors in a different way. Many of the buildings throughout the UK and Ireland date back many years, constructed of a wide range of materials and covering different types of building methods.

Bonfield flagged that this legacy housing stock needs to improve considerably if it is to continue to be fit for inhabitation in the years ahead. And it is a considerable volume of housing. As it stands it cannot meet government carbon emission and fuel poverty targets. These properties have also suffered as a result of poor quality work leading to poor thermal performance, particularly in the key areas of insulation and building fabric upgrade and maintenance.

When we say that we provide building specific solutions, that is what we mean. We know that different homes require different upgrade solutions. And that is why we work with all stakeholders in the process including architects, contractors, builders and owners to build specific solutions.

Upgrading Homes

In pointing to the inconsistent and inadequate work to date in upgrading homes, Bonfield said: “individual and any modifications need to take account of location, exposure, history, usage and state of repair, as well as architectural context. Too often there is very poor analysis and consideration of these individual factors prior to modifications being undertaken.

“This can be driven by scheme mechanisms to install fabric and energy efficiency measures at the lowest possible upfront cost. On occasion, inappropriate insulation has been installed in unsuitable buildings, with poor detailing or without adequate ventilation, etc. This can result in damage to the building fabric, consequent unexpected costs and health issues for the occupants.

For us, our priority is our clients’ home comfort and energy efficiency. Even in the most complicated retrofit projects on older buildings from experience we know we can provide the ideal insulation solution. It will protect the fabric of your home and help your property valuation.

Insulation Priorities

Bonfield added: “The whole of the building fabric needs to be understood and work undertaken in a proportionate and appropriate way. Addressing one element while ignoring others, or the interfaces, can generate problems. He has identified five aspects for consideration in taking retrofit forward to a satisfactory conclusion:

  • Liaising with consumers
  • Information gathering on the property and its vicinity
  • Design of the appropriate solution
  • How to make most efficient use of the home with the measures installed
  • Installation – quality and expertise.

In his introduction, Dr Bonfield writes: “ I recommend a new approach, underpinned by strong standards and enforcement. This will bring clarity and confidence to consumers, whilst providing a simplified and certain route to market for those companies, large and small, wishing to operate and do business in the energy efficiency and renewable energy sector in the United Kingdom.”

Starting Point

We believe that the weakness in the report is the starting point where all recommendations should be provided.

The ultimate aim for any proposal should be to insulate the whole property with the emphasis on “Thermal Bridge Free” upgrades and each homeowner explained where they occur, and what are the consequences of not addressing them.

Once these details are established, which are common on all properties, then training for all parties involved should take place and the communication process begins.

These critical junctions have always been present and all systems designers Should be aware of them but ultimately in the past they have been ignored due to a number of reasons.

Our issue is that the “Panel of Experts“ who have compiled this report were integral and part of the poor quality installations that have already taken place. Unfortunately this does not fill you with confidence that there will be drastic changes made.

Arguments over RHI Scheme Ignores Real Issue of Fuel Poverty

screenshot-2016-12-19-16-10-44As the controversial RHI scheme attracts political criticism amidst recrimination, blame and counter blame, local businessman Liam Brown of Enviroform Insulation in Warrenpoint has expressed his dismay at the broader implications for those people suffering from Fuel Poverty.

“This money could have been spent on insulating the very large number of properties across Northern Ireland where people are living in homes they can’t heat. Fuel poverty is a real issue whilst we are hearing of people burning fuel to heat properties that don’t need it for financial gain. It is immoral.”

He explained: “There are at least 10-15000 solid wall properties left uninsulated in Northern Ireland with the people living there, mostly in fuel poverty. They can’t afford to insulate their homes properly, so they are losing money on heating that is inefficient because much of the heat is lost through poor insulation. It is the Catch 22 of insulation. And it could be addressed.”

“If the government is serious about addressing Fuel Poverty, they could have done so. The value added benefits would have been local job creation for people installing systems, generating money back into the local economy. Also we would be less dependent on fossil fuel. It would also have generated VAT income for the government.

Liam Brown explained that Sammy Wilson at the time rejected the Green Deal when he was in post. The reasons weren’t clear even tough it made commercial sense.

“Aside from the political fall out from RHI and the point scoring going on, our politicians and commentators need to look at this broader issue which has been ignored in the furore over the catastrophic RHI scheme.

“£400 million would go a long way to addressing the issue of Fuel Poverty amongst those in most need in our society. It is a shameful situation.”

Is Your Thermal Cocoon a Horror Story?

Thermal Cocoon. What is it? Well, anyone remember the eighties horror film Cocoon. About the Aliens that lived in a swimming pool safe and secure in their cocoons? Obviously they were safe and warm in the swimming pool, the water couldn’t get in and they were secure. The Thermal Cocoon was complete, allowing the aliens to survive and thrive.

Is your Thermal Cocoon a Horror Story? Any Gaps in Your Thermal Cocoon?

Now imagine a bunch of aliens came to earth and set up in your home by getting in through a gap in your insulation. How would you fare? Do you even know if your insulation is alien proof let alone waterproof? Do you know where the gaps are? Think of all those aliens making their way across your thermal bridges? The horror.

There could be things getting in through your walls that you know nothing about. If your thermal cocoon is compromised or non existent, when moisture and damp gets in, it allows aliens like fungus and mould to grow on your walls, breaching your thermal cocoon every day and every night. Imagine coming down every morning to a sickly looking extraterrestrial who longs for the warmth of his native planet rather than your draughty cold abode. ET phone home? Or, ET phone Enviroform?

Insulation and Heat Transfer

So what is the connection between insulation and aliens you might legitimately ask? Apart from Cocoon, well there are several. Firstly the Space Shuttle. NASA has taken Aerogels to the next level beyond what was previously imagined, and uncovered a world of possibilities for this versatile material. It’s all about heat transfer or lack of. In other words, insulation.

According to Tori Woods, SGT Inc.
NASA’s Glenn Research Center Polymer-enhanced aerogels and polymer-based aerogels have numerous potential applications, both in space, on distant planets and on our own Earth. They are light, durable and extremely effective at insulating and preventing heat transfer.

Aerogels are among the lightest solid materials known to man and are created by removing moisture from a gel while maintaining the gel structure. The resulting material provides very effective insulation.

 NASA uses Aspen Aerogels’ product for cryogenic applications such as launch vehicles, space shuttle applications, life support equipment, and rocket engine test stands, there is an array of commercial industrial applications including pipe insulation, building and construction, appliances and refrigeration equipment, trucks and automobiles, as well as consumer applications, such as personal apparel. Most recently, the NASA-derived Aerogel has been applied to protect and insulate people’s hands and feet, the applications are endless.

Which brings us back to Cocoon, our 1985 comedy horror movie from Ron Howard which had that batch of aliens from the planet Antarea visit earth and set up home in a swimming pool in their cocoons.

The pool offered earthlings the gift of re-energy and life. If your Thermal Cocoon is breached, you may well find alien species growing in your house. And, if that is the case, who you gonna call? Ghostbusters or Enviroform Solutions?

Two Years On The Duncairn Centre Inspires

A heritage insulation retrofit case study Enviroform Solutions was proud to be the Insulation partner in a project to create one of Ireland’s most interesting new concert and arts venues, the Duncairn Centre in North Belfast. The refurbished centre is constantly delighting concertgoers with its comfort and quality. That is due in no small part to Enviroform Solutions innovative use of Spaceloft Aerogel insulation which is sympathetic to the unique requirements of this beautiful building.

Heritage Insulation Retrofit

Two years since it first opened its doors, the Duncairn Centre in North Belfast is still flourishing and inspiring. A stunning concert and Arts venue located on the Antrim Road, the Duncairn Centre for Culture and Arts is North Belfast’s first purpose built Arts and Culture shared space venue. A beautiful building with a distinguished heritage, insulation retrofit was the only way to upgrade the building without compromise.

Aerogel offered the only option in this project to maximise the energy efficiency without compromising the fabric.

This autumn it has featured a series of exciting concerts featuring the likes of Donal Lunny, Eddie Reader, Michael McGoldrick, Seamus Begley, Steve Cooney and Trevor Hutchinson. An concertgoers are constantly impressed by the quality and comfort in the refurbished former church.

Heritage Building with Aerogel Insulation

Heritage insulation retrofit by Enviroform Insulations. Spaceloft Aerogel Insulation and Duncairn Arts CentreThe building is listed Grade B+ by the NIEA due to its historic value as part of a unique complex owned by the Presbyterian Church and also due to its architectural merit as a fine example of de
corated Gothic style.

Doherty Architects, were commissioned to convert the disused church to a cultural centre. And due to the unique requirements of such a heritage property Enviroform Solutions were commissione to provide the insulation solution. Aerogel offered the only option in this project to maximise the energy efficiency without compromising the fabric.

“Our solution provided the highest thermal performance, taking up the least space because of the coping restriction which existed on the roof. In addition consideration had to be given to what we were doing would not affect the structure in anyway i.e. increasing the chances of dry or wet rot by condensation.”

“We did this by carrying out a WUFI assessment which looks at a number of factors like weather, orientation and comes up with a conclusion. It this case it reported that by installing Spaceloft Aerogel with certain intelligent vapour barriers then there was no risk.”

“The message is that Spaceloft Aerogel has a real benefit within the Heritage Sector adding real energy performance without risking the fabric of the building.”

The new £3.5million venue is a world-class facility consisting of 3 art studios, exhibition area, community meeting room, 170 capacity theatre/performance and rehearsal space, café/bistro and conference rooms. The Centre provides a platform for local and international artists to showcase their work as well as give the local community access to an arts and cultural programme of the highest quality. The project received a commendation in the Royal Society of Ulster Architects Awards in 2014.

Floor Insulation. Don’t Get Cold Feet

E-Therm Ultra Floor Insulation
E-Therm Ultra for all floor types.

The Problem: You own an old property with a solid floor, it’s not insulated or its badly insulated but for various reasons, excavation isn’t a realistic solution. You may literally be able to feel the cold and damp under your feet. What do you do?

The Answer? The solution is at hand. Enviroform Solutions have developed a flooring product called E-Therm Ultra which is the thinnest retrofit floor insulation product. It is also the highest performing floor insulation product around. Sounds nearly good to be true? Well it’s a fact. Read on.

Sort Out Your Floor Insulation and Save On Your Heating Bill

It is a reality that many of our older homes will have ground floors made from either annulated or poorly insulated solid concrete. The fact is that in the past builders didn’t really think that floors were a gap in what we like to call the thermal cocooning of the home. But in fact floors can be a big problem.

Heat loss through a solid floor can cost you money and drastically reduce the energy efficiency of your home. The attendant problems of damp and cold can lead to problems of mould and structural issues.

With E-Therm Ultra we can treat these solid floors to increase comfort levels and to save you on your household fuel bills. We have designed it specifically for buildings where space is at a premium/

The Technical Details

The panel consists of a 3mm high impact layer bonded to 10mm Aerogel insulation layers and then wrapped in a highly durable and robust vapour control layer.

No special tools or precautions are required when fitting the panels and they can be cut to the required shapes and size.

Domestic furniture can placed on top of the E-Therm Ultra which is compatible with most floor finishes and under-floor heating systems. It is supplied in a pre-formed panel to allow for fast installation.

We recommend the use of using Instalay’s self-adhesive underlay, so carpets can be securely fitted without the need for glue and edge fixed carpet grippers. The high impact layer of the E-Therm Ultra’s panel provides protection for the insulation layer against point loadings like heavy furniture and bedding.

Can it be Used on Laminate & Floating Floors ?

 Yes. Floating floors can be laid on top of the E-Therm Ultra’s panels, and again for best results we recommend using a high quality underlay, preferably Instalay adhesively fitted floors perform better for a longer period of time.

And On Ceramic Tiles 

To install ceramic tiles on top of the E-Therm Ultra’s flooring a 6mm tile backer board must be used on top of the floor to provide a stable fixing layer for the tiles.

The 6mm tile backer board is installed by fixing plastic fixings through the E-Therm Ultra’s to eliminate deflection making sure that the joints of the E-Therm Ultra’s and the tile backer board don’t overlap.

Once this is complete the tiles can be installed using a flexible tile adhesive and grouted as normal to finish.

What About Skirting ?

E-Therm Ultra’s skirting has been developed for a scenario when there is no internal insulation on the external walls of the property.

If the E-Therm Ultra’s Aerogel flooring panel is being used with either external or cavity wall insulation then it is highly recommended that the Aerogel insulation is returned up the inside edge of the external wall to prevent cold bridging at the junction.

E-Therm Ultra is supplied as a two part product, one being the foil wrapped Aerogel and the other being the profiled softwood skirting. This upstand can be achieved by use of our E-Therm Ultra Skirting.

If the thought of insulating your floor gives you cold feet, call us now.

 

Thermal Cocooning®. Eliminating Your Insulation Achilles Heel

Eliminate Your Insulation Achilles HeelEnviroform’s Thermal Cocooning® is the installation of a total building insulation layer that has no gaps. If there is a single gap in your insulation, that will be your building’s Achilles Heel.

In Greek Mythology it was prophesied that Achilles would die young. To prevent his death, his mother Thetis took him to the river Styx. There she dipped his body in the river, cocooning his body in the sacred waters to make him immortal. Unfortunately for Achilles his mother held him by the heel and so that part of his body remained vulnerable.

Thermal Cocooning®

With Enviroform Solutions’ Thermal Cocooning® there is no Achilles Heel in your insulation. No part of the building is left to chance, and there are no Cold Bridges. When we install a Thermal Cocooning® solution on any building, we develop a solution that suits the age, condition and the construction material used in the building. These are all essential considerations in a thermal upgrade to your home. If the solution isn’t tailored to your building then that is your insulation Achilles Heel.

After an epic life as a warrior, Achilles died when a poison arrow fired by Paris struck him on his heel. It was the one vulnerable point not part of the protective cocoon. It is a salutary lesson.

Our final solution is based on an initial consultation from which we custom build a design, which not only keeps you warm but also protects the long-term safety of the building and it’s occupants. Many older buildings have to be understood and respected before adding insulation and possibly incurring adverse effects.

We start with a blank canvas and look at the component parts and from the wide array of our innovative solutions, we put forward what is best suited for your home. During this process we are in constant contact with all the stakeholders, guiding them through the decisions they have to make depending on different factors that are important to them, for example budget, breathability, character, space and so on. Once this is completed we present our findings, which often include a number of options, to help the homeowner decide which solutions best fits their requirements.

Why Are We Different?

Why are we different to other insulation manufacturers or insulation distributors? Quite simply we use different types of insulation for certain points but our attention to detail never changes. So if a certain insulation manufacturer does not have a solution to a particular point in a building, then this detail tends to be ignored. The Achilles Heel in their methodology in turn becomes the Achilles Heel in your building, leaving it vulnerable to damp, cold and deterioration due to mould or heat loss.

Over the past number of years we have researched and developed, a range innovative products, that provides us with a suite of solutions, when pieced together, allows us to achieve Thermal Cocooning® on our projects.

For all our customers, and us, it’s about the return on your investment. We all want maximum return when we invest time or money in a project don’t we? At Enviroform Solutions we want to provide you with a long-term safe investment that will continue for the lifetime of your building. Otherwise, like Achilles, all your good work can be undone when the vulnerability is exposed.
