In the not too distant past, many DIY wallpaperers wouldn’t even prep the walls with filler before hanging wallpaper, leading to poorly hung, uneven wallpaper. Results like this put many DIY-ers off from decorating themselves – turning to professional decorators or just leaving their rooms as they were. But in the last decade or so, home décor brands have piled research into the problems facing DIY redecorators and came up with a series of solutions. Erfurt May have been one of the companies leading this trend with their Wallrock range.

Today we’re taking a look at the science and stats behind Wallrock Thermal Liner. It’s a lining paper that, unlike regular lining paper, also insulates your home. It uses a technology previously used in aeronautics to stop heat being lost through walls. It’s made from a secret thermal insulation material bonded to a durable, high quality lining paper. Using it can really help you save on energy bills.

It works by bouncing heat back into the room – the design of thermal liner means warm air is reflected back into the room when it tries to escape through walls. This retains heat and makes it quicker to heat up the room. A test found that using Wallrock Natural Thermal Liner can increase the speed a room heats up by 65%. When two rooms of identical size and construction were heated up, the one will thermal liner on the walls took 25 minutes to reach 21 degrees, while the one without took 60 minutes. What’s more, in rooms without thermal liner, 20% of the heat will be used up warming the walls themselves.

Wallrock Thermal Liner also has the benefit of preventing mould growth when used with Wallrock Thermal Liner Adhesive. It can also prevent sound transference between rooms and offers the smooth finish of regular paper liners.
