I have some really badly textured walls so do I need to take special precautions when applying Wallrock KV600 Thermal Liner over such poor surfaces?

Not really, just make sure the walls are clean, dry and solid before applying Wallrock KV600 Thermal Liner . If the texture is very deep as with some decorative plaster effects it is advisable to sand down the high points and use extra adhesive to help level the surface. We would advise that after hanging the first drop, stand back and make sure the results are satisfactory.

Where in the house can I use it to best effect?

Wallrock KV600 Thermal Liner is certainly most effective as an energy saver on outside walls and especially so if the walls are of solid construction (without cavities). However other key benefits of the product include acting as a sound insulation and covering over textured surfaces to produce a flat surface.

I remember those old polystyrene insulation tiles that were a fire hazard?

Wallrock KV600 Thermal Liner is classified as “E” according to DIN EN 13501-1 in relation to fire behaviour, which corresponds to “B2” (normally inflammable) according to the standard DIN 4102-1.

How it will look around light switches and skirting boards?

Wallrock KV600 Thermal Liner is 4mm thick and a neat finish is therefore possible in most applications, skirting, coving or light switches for example do not appear to be ‘sunk’ below the wall surface. Don’t forget Thermal Liner works best on outside walls, significant benefits can be achieved without the need to apply it to every internal surface.

Yes, and you must use ‘Wallrock Thermal Liner Adhesive’ as it is specially formulated to hang Wallrock KV600 Thermal Liner. We however ‘Do Not’ recommend you use within shower areas.

Wallrock KV600 Thermal Liner works in a different way to traditional insulating products. For a start we realise that rooms are rarely heated constantly 24 / 7. So Thermal Liner works by reducing warm up times dramatically as is begins to work immediately the heating is turned on because it is on the inside of the outside wall. Conventional products only work after the inside wall has being heated which can take hours – the very time you are likely to be in the room. Once the room has warmed up Wallrock Thermal continues to resist energy loss.

Yes you will save money and notice a significant change with Wallrock KV600 Thermal Liner,  especially when the heating is first turned on as room warm up time is reduced dramatically and the air currents that make you feel cold whilst the room warms up are also reduced. This is of course in addition to all the other benefits such as a reduction in noise through the treated wall.
