The SpaceRafter open web rafter system follows on from the SpaceJoist system, using the same metal webs in its construction.

SpaceRafter’s open web design provides deep insulation voids to increase thermal performance, long clear spans which may eliminate internal load bearing walls and a lightweight construction for easy handling on site, often without the need for specialist equipment.

The system can be constructed off-site as a roof cassette at the factory. Known as SpaceRafter Cassette, this room in the roof panel solution saves time, reduces costs and improves health and safety. Hinged roof panels made offsite improves build times onsite. Fast build times reduces labour, crane hire and scaffolding costs. The system improves H&S as you have a safe working platform to work from.
