Thermal Liners

Posted by Elisha Horobin on

With increasingly worrying climate change issues, the cost of living crisis, and household bills escalating, we are all trying to find ways to help improve the thermal efficiency in our homes and offices. Up to 35% of heat is lost through the walls, especially in older properties.  In order to become more thermally efficient you will need to invest in insulating your property, this can be very expensive, and cause a lot of disruption, for instance the use of cavity wall insulation, if you have a more modern house.  If however, you live in an older property, insulating it can be trickier, by adding either internal or external wall insulation.  Internal wall insulation will invariably steal room space, and external wall insulation may not always be possible or financially accessible. Thermal Liner is a great, simple, less disruptive, and cost effective way to way to improve your thermal efficiency.

What are thermal liners?

They are heavy duty lining papers that have been woven with durable textile fibres to add a layer of insulation to a room.  The Wallrock Thermal range come in 450gsm (approximately 3mm thick) and 600gsm (approximately 4mm thick) rolls. Simply stick to the wall with the recommended Wallrock Adhesive (the extra bond strength is required as they are weighty liners) as you would any other lining paper.

They are used to improve thermal insulation and efficiency in a home, and in turn help reduce energy bills.  Thermal wallpapers come with additional benefits of helping to reduce condensation; fighting issues such as damp and mould; and covering up any wall imperfections and cracks.

You can then paint over them, or if you prefer a flawless finish, cross line first with Wallrock Fibreliner Smooth lining paper, and then apply paint.
