Description

The SelectSIP Building System is the design, manufacture and installation of the wall, roof and floor structural elements of detached and multi-unit dwellings. The SelectSIP Building System consists of composite wall, roof and floor panels, utilising a rigid type-S EPS polystyrene foam core between 10mm thick Prime-Vita reinforced Magnesium Oxide board facing material.

The SelectSIP Building System is a structural system of internal and external walls, roof and floor panels of detached and multi-unit dwellings.

The SelectSIP Building System requires roof cladding installed over roof underlay and battens fixed to the roof panels, and window and door joinery, to make it weathertight. These are not included in the SelectSIP Building System.

The SelectSIP Building System does not provide a fire separation element where an FRR is required.
