The lightweight roof option

Our Xi Smart Extension Rooms are pre-manufactured into simple lightweight sections for easy access and installation. We use High grade EPS insulation which we install between the thermally efficient GRP frame work giving you U-values of just 0.1

Depending on ground conditions on where our extensions is to be located, typically the supporting feet can be installed upon basic concrete pads. This saves on extensive ground work having to be carried out in most cases, saving you time and money.
