Fully Insulated Structure

Mercia's Garden Rooms are fully insulated with 72mm thick walls and EcoQuilt insulation in between each timber cladding. The roof is also equipped with EcoQuilt, a UK-manufactured multi-foil insulation with a high-performance vapour control layer to prevent damp and moisture.

The AirTec insulated floor further reduces heat loss by trapping air in its bubble structure. Enjoy year-round comfort in your new space, with cool summers and warm winters.
