Description

The Formance Panels SIP Building System consists of a composite panel wall and roof system, utilising a flame retardant expanded polystyrene (EPS) core between layers of oriented strand board (OSB) facing material.

The Formance Ready^TM is a subset system and consists of 150 mm thick wall and ceiling panels.

The Formance Panels SIP Building System is a structural system of internal and external floor, walls, roof panels for use beneath roofing and cladding. The OSB facing may serve as an internal lining or provide a substrate for attachment of an alternative lining. The exterior facing OSB provides a substrate for attachment of exterior wall or roof cladding.
