Wallrock Thermal Liner | 75cm x 10m
Our most popular thermal liner. At 450gsm (approx. 3mm thick), Wallrock Thermal Liner helps rooms warm up faster, hold their heat for longer and cost less to heat, with worthwhile energy savings of around 15% on typical solid brick external walls. It's recommended by The Energy Saving Trust.
It also covers and reinforces tired, cracked plaster, plasterboard, blockwork and wood panelling, and helps reduce condensation, in many cases eliminating it.

How much do I need?
Multiply wall width x height to get the area in m², then add about 10% for trimming. Each roll covers about 7.5m².
Example: a 4m x 2.4m wall is 9.6m², so you'd need 2 rolls.
Is this the right grade for me?
- Thermal Liner 450 (approx. 3mm): a great all-rounder for most rooms and a good first step to a warmer home.
- Wallrock Thermal Liner KV600 (approx. 4mm): our thickest liner, best for very cold solid brick walls, north-facing rooms and problem areas.
How to hang it, in 5 steps
- Make sure walls are clean, dry and sound. Fill any large holes.
- Prime with Primer & Sealer and let it dry.
- Paste the wall (not the liner) with Wallrock Thermal Liner Adhesive.
- Hang the liner, butting the edges together, and smooth it out.
- Leave for at least 24 hours, then paint or wallpaper over it.
For the perfect finish
Thermal Liner can be painted directly. For a flawless finish, or if you want to hang decorative wallpaper on top, cross-line with Wallrock Fibreliner Smooth (avoid standard lining papers). Then finish with two coats of our Eco Friendly Paints. They're low odour, great coverage, and we can colour match too.
Good to know
- Damp walls: thermal liners aren't designed for walls that let damp through. If that's an issue, apply Wallrock Dampstop Thermic with Dampstop Thermic Adhesive first, then the Thermal Liner.
- Fire rating: Thermal Liner is Class E. It's a localised 'problem solver' for cold external walls. It isn't recommended for fire escape routes, such as hallways, landings and stairwells, unless finished with a fire-retardant covering such as Wallrock Fireliner (fire rated Class 0), hung with Wallrock Fireliner Adhesive. It also isn't suitable for new builds and extensions where Building Regulations apply.
