Wallrock Brochure DownloadEST logoWallrock Thermal liner KV600 is the most effective member of the Wallrock Thermally Efficient Wallpaper range. It has been listed by the Energy Saving Trust because of it thermal efficiency and energy saving properties. Being 4mm in thickness and offered in a roll of 15m², twice the coverage of standard Wallrock Thermal Liner. Wallrock Thermal Liner KV600 offers very worthwhile energy savings, well in excess of the 15% standard Wallrock Thermal Liner provides on typical solid brick external walls. Wallrock Thermal Liner KV600 works to save energy from the moment heating is turned on by slowing down the rate at which a cold walls soak up heat energy - and allowing the room to warm up considerably faster, in many cases more than halving warm up times, creating a comfortable room environment with less energy. This effect is valuable in any home with solid walls and even those with external or cavity insulation - especially where the heating is regularily turned on and off. Once the room is warmed up and comfortable, Wallrock Thermal Liner KV600 goes on working producing steady energy savings.

Furthermore Wallrock Thermal Liner KV600 has excellent capacity to cover and reinforce poor plaster and other surfaces such as plasterboard, blockwork and woodpanelling.

Wallrock Thermal Liner KV600 also helps reduce condensation problems and in many cases eliminates them - as much more room warmth is retained at the wall surface at an earlier stage in the warm up phase there is far less opportunity for condensation to form on a cold wall and consequently a reduced risk of unhealthy mould growth.

The surface of Wallrock Thermal Liner KV600 is longlasting, durable and suitable for painting directly, although for a perfect finish we recommend cross lining with Wallrock Fibreliner Original, Wallrock Fibreliner Smooth or Wallrock Fireliner (avoid the use of standard linings) which allows not only painting but the application of decorative wallpaper.

This product is suitable as a localised ‘problem solver’ for cold external walls and is not recommended for use in fire escape routes inside your home unless the surface is further treated with a fire retardant covering. This product is class E fire rated and should not be used for projects such as new builds and extensions where Building regulations are applicable.

Fire Safety

table

  1. Ensure that base surfaces are clean, dry, firm and free from any loose or flaking material.
    Wallrock Thermal Liner KV600 can also be applied in some circumstances directly over cracked and light to medium textured surfaces which are firmly adhered and stable - in such cases it is always advisable to cover a small test area before continuing.
  2. Apply the Wallrock Thermal Liner Adhesive generously to the wall using a roller. Use a brush or spatula to apply adhesive to areas the roller cannot reach.
    On textured or damaged surfaces it is especially important to apply a generous layer of adhesive.
    Apply enough adhesive to apply one length of Wallrock Thermal Liner KV600 at a time ensuring the pasted area exceeds the width of the Wallrock Thermal Liner KV600 (see paste consumption guide).
  3. Always apply Wallrock Thermal Liner KV600 with the smooth Wallrock face to the outside, furry side to the wall. Apply Wallrock Thermal Liner KV600 directly from the roll onto the wet adhesive and slide into place. Smooth out any bubbles with a roller or similar. Leave a small amount of surplus material for trimming where necessary.
  4. Cut off any excess Wallrock Thermal Liner KV600 at the ceiling, floors and corners using a trimming knife with a hooked blade in combination with a forming board. Alternatively carefully mark the Wallrock Thermal Liner KV600 using a pencil and trim with scissors.
    On external corners a ‘corner profile’ can be used to give a neat finish or flexible filler can be used to caulk the exposed edge of the thermal liner - especially important if you intend to paint the thermal liner KV600  without applying Wallrock Fibreliner
  5. Allow at least 24 hours for drying, longer if conditions are especially humid or cold. Wherever possible we also recommend that the Wallrock Thermal Liner KV600 is allowed to dry out naturally and therefore the heating is turned off whilst the adhesive dries out. However if temperatures are likely to drop below 10°c/50°F it is advisable that low level heating is used to ensure that the adhesive can cure effectively.
  6. If you do not intend to cover the product with fibreliner or similar then any small gaps at seams and corners can be filled and sanded prior to painting the surface directly with standard emulsion paint. Use a good quality, flexible non shrinking filler.
  7. To create a superior finish for paint or printed wallpaper we recommend that the Wallrock Thermal Liner KV600 is lined over with ‘Wallrock Fibreliner’, (this product is very strong and dimensionally stable and compliments the Wallrock Thermal Liner KV600 perfectly). Other ‘Paste-The-Wall’ linings may be compatible but on no account should you line the product with a traditional lining as problems with lifting at seams may be encountered.

Warning
To minimise the hazard in the event of fire, do not apply wallcoverings over expanded polystyrene veneers and ensure the wallcoverings are always firmly stuck down as loose wallcoverings may contribute to the hazard. Surfaces painted prior to 1960 may contain lead pigments and special precautions should be taken when preparing these surfaces.

Typical paste consumption guide:
8-10kg of adhesive per roll, The adhesive consumption indication is for guidance only, on walls in good condition less paste may be required whereas on damaged or textured walls and surfaces that are not vertical, more paste may be required.

This is a simple wallpaper calculator and should be used as a guide only. You can find the roll width and roll length you are after on the specific product page.
Roll widths are provided in meters (such as 0.5 x 10mtr) so your wall widths and heights should be inputted in meters also.
If you are purchasing an offset match product then you may need a little extra as there may be some waste. If you have any windows or doors in your walls you can simply ignore these. This will give a good estimate of required roll numbers.
