Metal Web Joists

Posi-Joist™ combines the lightness of timber with the strength of the Posi-Strut™ steel web to form the most versatile open web system available to the modern building designer. With greater spans and design flexibility the Posi-Joist™ gives you unequalled design freedom across a wide range of applications for both floor and roof in domestic, industrial and commercial structures.

Roof Trusses

Trussed rafters are individually designed prefabricated structural components made from strength-graded timber members of the same thickness, joined together with punched metal plate connectors. They provide a structural framework to support the roof fabric of a building, room ceilings and, in some cases, floors.

Breather Membranes

Protect TF200 Thermo is a high performance timber frame membrane with high tear strength, weather resistance and vapour permeability.

Vapour Control

Protect VC Foil Ultra is a robust highly reflective low emissivity vapour control layer which has been developed to enhance the thermal performance of walls, ceilings and floors and now offers Class 1 Surface Spread of Flame to BS476-7.


HYBRIS is a reflective insulation product based on a honeycomb structure made of shaped polyethylene foams glued to aluminium coated polyethylene foils.


EGGER Protect is made from EGGER P5 flooring grade chipboard with a durable, anti-slip, weather resistant surface layer. This surface layer is applied to both the top and underside of the board, resulting in a product that offers protection from moisture penetration, not just during construction but for the life of the floor.
