SpaceJoist Metal Open Web Floor Fabrication
SpaceJoist offers a comprehensive range of depths from 195mm as a direct alternative to solid timber joists and I-joists, up to 424mm which is ideal for large spanning commercial applications.
Services can be passed through the open web feature. SpaceJoist have European Technical Approval (ETA). All ITW CP licensed fabricators CE mark their SpaceJoist or SpaceRafter to legally comply with the construction products regulation.
This includes an external quality assurance system and clear labelling of every joist and rafter.
Benefits of SpaceJoist System
Long Spans
Longer spans are achievable in comparison to solid timber. This may eliminate the need for intermediate load bearing internal walls, reducing a building’s overall cost.
Reduced Wastage
Manufactured to size eliminates site alterations saving time on site.
Design Flexibility
SpaceJoist can be designed top hung to eliminate the rim board in timber frame construction, improving air tightness and reducing thermal bridging.
Less Timber and Fewer Webs
Tests show that the NEW SpaceJoist system requires less construction material, saving cost.
Sound Performance
SpaceJoist delivers outstanding acoustic performance to comfortably pass English and Welsh regulations, even complying with the more stringent 43dB Scottish regulations without additional insulation, plasterboard or resilient bars.
Fire Performance
NEW SpaceJoist category C open web floor solution is approved by the Structural Timber Association (STA) in their product paper 4 as an acceptable option to achieve a fire robust solution during the construction process.
Easy to Handle
Now even lighter, the lightweight construction makes SpaceJoist easy to individually move on site without the need for crane hire. Alternatively, floor and roof sections (cassettes) can be delivered to site and craned into position to save build time.
Wide Nailing Surface
Fixing of floor and ceiling materials is simpler and quicker due to the minimum chord width of 72mm.
Highly Engineered
SpaceJoist are manufactured off-site ensuring consistent quality and reliability.
Open Web Design
Fast and simple installation of services, without the need for drilling or notching. Joists can accommodate large services such as mechanical heat recovery systems.
Home Grown Timber
SpaceJoist can be manufactured in home grown timber, reducing carbon footprint.
Attic Bottom Chords
SpaceJoist can be incorporated into attic truss bottom chords to achieve greater spans, deeper insulation and provide a service void.
Typically achieve greater maximum spans with less double webs and timber:
- Extra teeth improve SpaceJoist stiffnessand strength which reduces deflection.
- Burst-through holes increase web strength in compression.
- Contact tabs aid load transfer from webs to timber chords, increasing web capacity
