SpaceRafter
SpaceRafter offers a smarter way to frame roofs, combining offsite efficiency with flexible support design.
Modern roof alternative
About SpaceRafter
SpaceRafter offers significant advantages over traditional roof construction methods, enabling faster and more efficient build programmes. It can be supplied either pre-insulated or as factory-manufactured roof cassettes, reducing on-site labour, improving installation speed, and enhancing build quality through offsite precision.
The system also provides excellent thermal performance and consistency, helping to meet modern energy efficiency requirements.
SpaceRafter can be designed to create a ‘room in the roof’ – maximising usable living space within the roof structure while maintaining structural integrity and simplifying the overall construction process.
Key Features & Benefits
Long Spans
Longer clear spans can be achieved than with solid timber, requiring fewer intermediate supports, saving time on site.
Thermal Performance
Rigid, blown or quilt insulation can be fitted inside voids to improve thermal efficiency.
Cassettes
Available in cassettes to increase construction speed on site.
Easy to Handle
Now even lighter, the lightweight construction makes SpaceRafter easy to individually move on site without the need for crane hire.
Versatile
Can be used on both residential and commercial buildings.
RETROFITTING
Retrofit SpaceRafter
By pairing SpaceRafter with SpaceJoist, existing roof trusses can be replaced to form a functional room-in-roof space.
All projects require a full structural design and method statement from a qualified designer before any work is undertaken.
Loose SpaceRafter
Supplied loose for residential and commercial builds, SpaceRafter can incorporate rigid insulation between the timber chords for improved thermal performance.
Fully Assembled Roof Cassettes
For residential and commercial applications, SpaceRafter can be delivered as fully assembled roof cassettes, incorporating multiple rafters along with sheathing, plasterboard, and insulation for fast, efficient on-site installation.
