In fact Wallrock thermal Liner has been around for about 2 years now but is one of those well kept secrets ! It has been specially developed to offer a combination of features. First and foremost as an thermal insulating energy saving product, but lets look at some of its other benefits such as the ability to bring rough old plaster or textured surfaces back to a perfect flat surface. You can also add sound absorption, mould resistant and damp formation fixing are just a couple more.

Thermal Liner Features

• reduces room warm up times
• covers cracked surfaces and damaged plaster
• back to flat capability
• combats mould and damp formation for a healthier home
• allows your walls to breathe
• produces a tough stable surface for other wallpaper or paint
• significant energy savings
• contains no PVC or fibreglass
• fire rated

To achieve this Erfurt Mav have combined their established Wallrock Fibreliner ‘know how’ with technology originally developed for the aerospace and automotive industries.

Features and Benefits of the Thermal Liner

Energy saving

When a room has been lined with Wallrock Thermal Liner it reflects warm air back into the room from the wall surfaces. Therefore, the maximum amount of heat is available to heat up the room air. Rooms thus become warmer up to 65% more quickly and with reduced use of energy. This is especially effective for homes with thermostatically controlled heating.

If the walls are not covered with Wallrock Thermal Liner, the majority of the energy will initially be used to heat up the walls. Only then can the room air be heated up to the required temperature and take on a feeling of warmth and comfort. It is a very different picture with walls covered with Wallrock Thermal LIner: the ‘wall’, the sluggish reservoir of cold, becomes as it were ‘disconnected’ from the room and the temperature at which people feel comfortable and warm in a room is reached very quickly. The energy saving effect of this wall covering even aids houses well insulated with External Thermal Insulating Composite Systems (ETICS).

Wallrock Thermal Liner energy saving effect

In a comparative room, the walls of which have been covered with Wallrock Thermal Liner and wallpaper, the required room temperature of 21ºC is reached after only 25 minutes. It would take 100 minutes to reach this temperature using the same heating energy but with a conventional wall structure.

Mould prevention

Walls, which have a surface temperature that is distinctly cooler than the ambient temperature, are an ideal breeding ground for 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. The moist walls then form a perfect breeding ground for mould to grow.

Permeable Wallrock Thermal Liner is the solution to walls with this kind of problem. It increases the surface temperature of the wall, prevents condensation and therefore stops mould from forming.

Sound absorption

Wallrock Thermal Liner provides pleasing acoustics thanks to its high degree of noise and sound absorption. The degree of absorption in the audible range on unpainted or uncovered Thermal Liner is on average aw=0.02. This figure corresponds to the acoustic performance of a 5mm thick velour carpet.

Crack coverage

The high level of elasticity in the flexible fibres and 3.5mm thickness of the material enable class A and B cracks in base surfaces to be covered very well.

Coverage of texture

Moreover, Wallrock Thermal Liner also provides excellent coverage of slightly to medium textured base surfaces without pre-levelling.

Permeable Wallrock Thermal Liner is the solution to walls with this kind of problem. It increases the surface temperature of the wall, prevents condensation and therefore stops mould from forming.
