Walls, Floor, and Roof

SIPS (Structurally Insulated Panels)

SIPS are one of the most environmentally responsible building systems available. A SIPS garden office building provides extremely high levels of insulation and is extremely airtight, meaning that the amount of energy used to heat and a cool a room can be cut by up to 50 percent.

SIPS garden office buildings are more energy efficient, stronger, quieter and more draft free than older technology systems, like timber framing.

Less air movement or leakage translates into less drafts, fewer penetrations for noise, lower energy bills and a significantly more comfortable and controllable indoor environment. The result is lower energy consumption and CO2 emissions. And the best bit is that garden office buildings using SIPS really won’t cost the earth … in more ways than one.
