Insulated plasterboard for interior work – Thermano GK-H2 50 mm

Renovating a corner room can be a good opportunity to improve comfort while retaining the façade. PIR insulated plasterboard combines thermal insulation with a room-side lining, useful where both space and the sequence of work are important.

The PIR foam restricts heat flow and its bonded plasterboard face provides the finishing surface. Fewer layers have to be assembled separately on site. Once joints are treated, the wall can be prepared for painting. In a single-room refurbishment this brings thermal upgrading and redecoration into one sequence of work.

The depth of an internal lining affects usable space. PIR’s insulating performance can leave more room for a desk, a wardrobe or a passage beside a bed. In compact utility rooms, even a few centimetres can affect furniture placement and access to doors and recesses.

In a compatible loft system, bonded boards insulate the roof slopes and provide a flat lining in the same operation. A thin build-up matters near a low eaves wall. It can leave more usable space for a study or bedroom beneath the slopes.

Factory bonding keeps the lining aligned with the insulation. Each piece can be fitted as a unit, which simplifies work when the rest of a home remains occupied. The resulting plasterboard surface can be finished with paint and trim as the room is redecorated.

Match internal insulation to the existing wall’s moisture conditions and detail the joints carefully. In humid rooms, both the facing and the complete system must suit the exposure. A properly designed lining can provide a warmer internal surface and a base for finishing while keeping the build-up compact.
