Posted by Victoria Yardley on
With heating bills still climbing, keeping warmth inside your home matters more than ever. One of the simplest upgrades you can make is thermal wallpaper. At Victory Colours we stock the Wallrock Thermal Liner, an easy way to add insulation to your walls and cut the cost of heating your home.

What is thermal wallpaper?
Insulating wallpaper and thermal liners add an extra layer of insulation to your walls. The Wallrock Thermal Liner is recommended by The Energy Saving Trust for its efficiency and energy-saving performance. It is made from an advanced heat-retaining material bonded to a high-quality lining paper, so rooms warm up faster and stay cosy for longer. Over time, that retained heat can noticeably reduce your heating bills.
Benefits of thermal wallpaper
As well as helping to significantly reduce heating and energy costs, the Wallrock Thermal Liner:
- Is simple to apply
- Can insulate any room
- Minimises condensation
- Helps combat common household issues like damp and mould
- Significantly reduces room warm-up time
- Covers uneven surfaces such as cracked walls
- Allows walls to breathe
- Helps with sound insulation
Thermal wallpaper FAQs
Can I paint thermal wallpaper?
Yes. The Wallrock Thermal Liner has a smooth outer face designed to be painted. We recommend waiting at least 24 hours after hanging so the paste can dry fully before you paint.
For an even smoother finish, cross-line the Wallrock Thermal Liner with Wallrock Fibreliner Smooth and Wallrock Power Adhesive. This gives you a super smooth surface for wall paints.
How thick is Wallrock Thermal Liner?
It comes in two grades. The KV600 is the thickest in the range at 600gsm (approximately 4mm thick). The standard Wallrock Thermal Liner is 450gsm (approximately 3mm thick) and offers worthwhile energy savings, for example 15% on typical solid brick external walls.
Which wallpaper adhesive should I use?
We recommend Wallrock Thermal Liner Adhesive, a high bond strength adhesive formulated specifically for heavy Wallrock thermal wallpapers.
It is designed to create the perfect base for decorating: its formula covers cracks and smooths imperfections, saving you time and money on wall preparation. It is ready mixed, easy to use and non-drip. It is ideal for Wallrock Thermal Liners, insulating liners and heavy contract vinyl papers, and like all Wallrock adhesives it contains a safe fungicide.
How much do I need?
Measure the width and height of each wall and multiply them to get the area in m². Then add about 10% for trimming.
- Wallrock Thermal Liner 450 (75cm x 10m) covers about 7.5m² per roll
- Wallrock Thermal Liner KV600 (100cm x 15m) covers about 15m² per roll
Example: a 4m x 2.4m wall is 9.6m², so you'd need 2 rolls of the 450 or 1 roll of the KV600.
Which grade is right for me?
- 450gsm (about 3mm): great all-rounder for most rooms and a good first step to a warmer home.
- KV600 (about 4mm): our thickest liner. Best for 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.
