Wallrock ThermaWall Premium Thermal Liner - Energy Efficient Wall Insulation for Home & Office - Reduce Heating Costs & Improve Comfort

Wallrock ThermaWall has been specially developed to offer a combination of features:

• Thermal insulation and energy saving for walls and ceilings
• Great for damaged walls – at 3.5 - 4 mm* thick it’s perfect for covering damaged and textured walls
• 50cm wide - being narrower than traditional Wallrock Thermal Liner and KV600, means that ThermaWall is much easier to handle and also makes it more suitable for smaller areas such as window reveals.
• Mould Prevention - ThermaWall allows walls to breathe and raises the room temperature meaning it will help to combat mould growth
• Great surface for paint or paste-the-wall wallpapers (read more below if you'd like to use paste the paper wallpapers)

Independent test results – British Board of Agreement (BBA)

“When Wallrock Thermal Liner is applied to a solid wall dwelling with a U Value of 2.1 W/m2K the resulting U Value is improved (i.e. reduced) to 1.79 W/m2K. This represents a saving of 15% in the static heat loss. Its Thermal Resistance has been measured at 0.0821 m2K/W.” To view the full document, please . This information is based on a lighter weight product, so the energy savings with ThermaWall will be higher based on the same application specified.

Application Advice:

Dos:

• Put the ‘fluffy’ side put against the wall, so the smooth surface faces the room
• Remember, the liner is absorbent, so be generous when pasting with Wallrock Thermal Liner Adhesive (2-3kg per roll)
• Have a set of sharp blades available before you start
• When going around sharp corners butt-joint separate drops
• Use normal emulsion paint over the Wallrock ThermaWall
• Try our paste-the-wall wallcoverings to get smoother / different finish on the ThermaWall, use paste-the-wall wallcoverings – more about further down on this page

Don'ts:

• We do not recommend applying traditional wallpapers or lining papers over ThermaWall because these products, by nature, expand when wet and shrink when drying up (paper-based products are dimensionally unstable), which can cause the corners of Wallrock ThermaWall to be pulled off. All Wallrock products are dimensionally stable. You can use Wallrock Fibreliners directly over the Thermal Liner (read below about Finish on Wallrock ThermaWall).
• If you'd like to hang traditional wallpaper over the ThermaWall, please hang Wallrock Fibreliner on top of the ThermaWall first and then you can apply your wallpaper. In addition to preventing the lifting of the corners and seams of the ThermaWall, it will allow you to remove the wallpaper in the future without damaging Wallrock ThermaWall.
• We'd not recommend putting ceramic tiles over the ThermaWall. If you want to hang ceramic tiles over the ThermaWall, please use the instead.

• Helps with sound acoustics
• NO PVC or glass fibre
• ThermaWall is classified as „E “according to DIN EN 13501-1 in relation to its reaction to fire behaviour, which corresponds to „B2“(normally inflammable) according to the standard DIN 4102-1
• If you'd like to improve the fire rating of the thermal liner, please use .

Finish on Wallrock ThermaWall

Please note that the surface of ThermaWall is an excellent surface for paint, however, if you want to create a better / different finish quickly and easily use , or (flat finish) or and for a textured finish. These liners can be applied directly over the thermal liners. If you'd like to improve the fire rating of the ThermaWall, please use Wallrock FIRELINER Class 0.

Mould prevention

Walls that have surface temperature distinctly cooler than the ambient air temperature are typically affected by mould. This is why the problem is often seen on outside walls and close to windows. The warm and moist room air condenses on the cooler areas of the walls and creates condensation. Wallrock ThermaWall increases the surface temperature of the wall preventing condensation and therefore stops mould from forming.

FAQs:

Does Wallrock ThermaWall work?

We have all the evidence that it does. Apart from verifying the product through tests, our customers confirm this too through feedback and repeated purchases. Read reviews on the product page.

Do I need to put another liner over ThermaWall?

No. Wallrock ThermaWall has been designed to be ready for final decorating, but everything depends on the wall condition and sometimes it’s required to use paste-the-wall liners on top of the ThermaWall to get better finish.

Which side should go against the wall?

The ‘fluffy’ side should go against the wall and the flat side is facing the room.

Can I paint Wallrock ThermaWall?

Yes, you can paint Wallrock ThermaWall using emulsion paint.

Can I use traditional wallpaper or lining paper over the ThermaWall?

We advise against it because traditional wallcoverings expand when wet and shrink when drying, which could cause the ThermaWall to lift at the corners or seams. Use Wallrock Fibreliners or Armadillo range of wallpapers for a better finish. Please get in touch with us if you are still unsure how to go about choosing the right products.
