This 3m x 2m Insulated Garden Room creates the perfect way to make the most of your garden, while in the comfort of the indoors all year round, thanks to the Eco-quilt insulation that features in the walls, roof, and floor. The walls are consisting of three layers, a 16mm tongue and groove outer layer, a 44mm gap in the middle that is filled with insulation, and a 12mm tongue and groove inner wall. The thick walls mean heat is trapped in and any entering noise from the outside is greatly reduced. Each window used in this building is double glazed as standard and filled with argon, helping to retain the warmth all year round. We use an EPDM rubber to cover the roof of this building, EPDM is a membrane designed by Firestone that offers incredibly resilient and long-lasting protection against the British weather.An added bonus with this insulated log cabin is that it does not require planning permission from the local authorities because it is under 2.5m in height. We do advise you check
