Solent Roof Trusses LTD design and manufacture the ITW Space Joist metal web system. Metal web joists are commonly known as easi-joists, posi-joists, space joists or eco-joists.
Not only do these joists out perform sawn timber in span and dimensional stability, the added benefits of a greater bearing area and open web system make them easier to install for the carpenter, plumber and electrician, reducing valuable time and cost.
Features & Benefits
Long spans: Longer spans are achievable in comparison to solid timber. This may eliminate the need for intermediate load bearing internal walls, thus reducing a building’s overall cost.
Reduced wastage: Manufactured to size eliminates site alterations saving time on site.
Design flexibility: SpaceJoists can be designed top hung to eliminate the rim board, decreasing the risk of timber shrinkage to improve air tightness.
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 regs without additional insulation, plasterboard or resilient bars.
Easy to handle: Now even lighter, the lightweight construction makes SpaceJoist easy to individually manhandle 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.
Engineered: SpaceJoists are manufactured offsite 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: SpaceJoists can be manufactured in home grown timber - reducing carbon footprint.
Attic bottom chords: SpaceJoists can be incorporated into attic truss bottom chords to achieve greater spans, deeper insulation and provide a service void.
