Wallrock Thermal Liner is an efficient wallpaper listed by the Energy Saving Trust because of its thermal efficiency and energy saving properties.

Being 450gsm (2-3mm in thickness) it offers worthwhile energy savings, for example 15% on typical solid brick external walls (see BBA certificate).

Thermal Liner has excellent capability to cover and reinforce poor plaster and other surfaces such as plasterboard, blockwork and wood panelling.

Wallrock Thermal Liner also helps reduce condensation problems and in many cases eliminates them and reduces risk of unhealthy mould growth.

Thermal Wallpapers work to save energy from the moment the heating is turned on, by slowing down the rate at which cold walls soak up heat energy.

Wallrock allows the room to warm up considerably faster, in some 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 regularly turned on and off.

Once the room is warmed up and comfortable, Wallrock Thermal Liner goes on working, producing steady energy savings.

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.

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.

3mm Wallrock Thermal Liner 450gsm Installation Guide:

 · Ensure that base surfaces are clean, dry, firm and free from any loose or flaking material.

 · New plaster is very absorbent and will require one to two coats of Wallrock Primer & Sealer before applying any wallcovering, including Wallrock Thermal Liner to the surface.

 · Wallrock Thermal Liner can also be applied in some circumstances directly over cracked and light to medium textured surfaces which should be firmly adhered and stable.

 · It is always advisable to thoroughly clean the surface and use one coat of Wallrock Primer & Sealer, it is advisable to carry out a small application test before continuing.

 · 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 at a time ensuring the pasted area exceeds the width of the Wallrock Thermal Liner (see paste consumption guide).

 · Always apply Wallrock Thermal Liner with the smooth Wallrock face to the outside, furry side to the wall.

 · Apply Wallrock Thermal Liner 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.

 · Cut off any excess Wallrock Thermal Liner 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 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 without applying Wallrock Fibreliner.

 · Allow at least 24 hours for drying, longer if conditions are especially humid or cold.

 · Wherever possible we also recommend that the thermal liner 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.

 · 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.

 · To create a superior finish for paint or printed wallpaper we recommend that the Thermal Liner is lined over with ‘Wallrock Fibreliner’.

 · This product is very strong and dimensionally stable and compliments the Thermal Liner 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.

 · If applying a printed or textured wallpaper directly to the Thermal Liner, fill any open seams and gaps first and ensure a ‘Paste The Wall’ product is used.

 · Every effort is made to ensure all rolls reach you in perfect condition, but faults can occur from time to time.

 · Before hanging please check that each roll of Wallrock Thermal Liner is undamaged.

 · Please retain all labels, we will require them if you have a problem.

 · We recommend that after hanging no more than 2 lengths that the result is inspected before continuing.

 · We cannot accept claims for consequential loss in respect of visible defects apparent prior to hanging.

 · Typical paste consumption guide : 5kg 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.

 · 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.
