What is thermal wallpaper?

Thermal wallpaper and liners are a way to add an extra layer of insulation to your walls.

Thermal wallpaper FAQs


Can I paint thermal wallpaper?

The Wallrock Thermal Liner is designed to be painted with its smooth outer facing side. Although we recommend leaving at least 24 hours after applying the thermal wallpaper to the wall to allow the paste to dry before painting over it. 


For a smoother finish, cross line the Wallrock Thermal Liner with Wallrock Fibreliner Smooth and Wallrock Power Adhesive.  This excellent liner offers a super smooth surface for wall paints.

How thick is Wallrock thermal liner?

The Wallrock thermal liner comes in two grades, the KV600 which is the thickest in the range and is 600gsm (approximately 4mm thick), and then the standard Wallrock Thermal Liner which is 450gsm (approximately 3mm thick) which offers worthwhile energy savings, for example 15% on typical solid brick external walls.

Which wallpaper adhesive should be used?

We recommend using the Wallrock Thermal Liner Adhesive, a high bond strength adhesive, especially formulated for the heavy Wallrock Thermally efficient wallpapers.


The Wallrock thermal liner adhesive has been specially developed to create the perfect base for decorating. Its unique formula covers cracks and smooths imperfections which allows you to save time and money and minimises wall preparation. Wallrock Thermal Liner Adhesive is ready mixed, easy to use and has a non-drip formula. It is ideal for use with Wallrock Thermal Liners, insulating liners and heavy contract vinyl papers, it also contains a safe fungicide as with all Wallrock adhesives.
