This stunning 3m x 3m Insulated Garden Office offers a modern building that is both practical and stylish. You can position the panels of the building to your specification, moving windows and walls to your requirements giving you a bespoke building. The PVC windows and doors of this garden room are double glazed, with two of the glazed panels including opening top windows.

EcoTherm is a high performance insulation with a fibre-free rigid thermoset polyisocyanurate (PIR) core.

It is used to insulate solid concrete and suspended timber ground floors, and has a thermal conductivity of 0.022 W/mK.

The price of this item includes full installation of the building into your garden. A firm and level base is required for this, we recommend either solid concrete or concrete slabs. It is recommended that the floor of this garden room is further covered by either carpet or laminate to reduce wear on the match boards.

Please Note: These Insulated Garden Offices are Pressure Treated but not painted. Although Pressure Treated you will need apply and an application of wood preservative which is not part of the home installation service. In order to qualify for our 15 year anti-rot guarantee the building must be annually treated with a high quality spirit based wood preservative.
