3M X 4M(D) Insulated Garden Room

This 3m x 4m Insulated Garden Room is an incredibly versatile building that can be used all year round thanks to the Eco-quilt insulation that features in the walls, roof and floor. The walls are consist 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. The roof and floor are built using 16mm tongue and groove cladding and also utilise the same Eco-quilt insulation within their construction. 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.

Mercia Insulated Garden Rooms are manufactured here in the UK, using sustainably sourced and regulated timber. An added bonus with this Insulated Garden Room 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 with your local authority to confirm this. All of our insulated garden rooms are fully installed for you as part of the price you pay, meaning all you have to do is sit back and relax whilst our installers erect your new building.
