The double glazed doors and windows, and fully insulated walls, floor and roof provide good thermal efficiency to help maintain the temperature inside your garden room. This ensures you can maximise the use of your garden room all year round, whatever the weather outside. The walls and floors come as sandwich panels with a polyisocyanurate core. This insulation has low conductivity, giving it great insulating properties that are far superior to alternative materials such as polystyrene or rockwool. A well insulated garden room will be eco-friendly and beneficial to the environment in helping you to reduce your carbon footprint.

The Addroom can be built onto consolidated groundwork, such as concrete or paving slabs. The whole garden room building sits on pressure treated floor bearers, to help give it a solid foundation. Pressure treatment forces a wood preservative, deep into the timber to ensure it is fully protected. This is why we can offer a genuine 10 year guarantee on pressure treated timbers* against rot and insect infestation. The bearers are the part of the construction in contact with the cold damp ground so it is important they are protected, otherwise they could quickly deteriorate and put your garden room at risk.
