Gang-Nail Truss Frame
The innovative alternative to traditional timber frame walls.
Using our proven method of Customer-Back Innovation and listening to market challenges, we’ve created a new solution. Gang-Nail Truss Frame, the innovative alternative to traditional timber frame walls.
A system of standardised wall elements, made offsite, that combine into larger modules on-site. The Gang-Nail Truss Frame wall elements are made up of timbers pressed together at the joints using Gang-Nail nail plates.
Features:
Low U-Values
The Gang-Nail Truss Frame structure allows a lesser amount of insulation to be wrapped around the wall panel’s external face, eliminating thermal bridges and saving on material. U-values of 0.18 W/m²K and lower is easily achievable, meeting new Part-L standards.
Superior Wind Load Resistance
Gang-Nail Truss Frame is made as wall elements using Gang-Nail nail plates to press the timber joints together. The structural strength achieved from this design method results in superior resistance to wind loading compared with traditional timber frame. This means less requirement for steel goal posts and the elimination of sheathing.
Pre-Defined Values
Gang-Nail Truss Frame structural elements have pre-defined values based on external testing of the panels. This means Building Designers can rely on the published values all the way through from design to on-site construction. This also simplifies calculations in case of re-design, saving time and reducing complexity.
Fire Tested
Gang-Nail Truss Frame has achieved and exceeded 30 and 60 minutes fire tests, making it a safe and certified alternative to traditional timber frame.
Slimmer Width
Gang-Nail Truss Frame external walls with insulation, membranes and the frame itself are up to 60mm narrower width than a traditional timber frame panel. This potentially means a per plot saving of up to 120mm resulting in reduced foundation footprint and the option to fit more homes on multi-site developments.
Factory Built-in Tolerance
Gang-Nail Truss Frame elements can be produced with factory built-in tolerance to allow adjustments on site for variations in foundations. Tolerance can be allowed for at the end of the panels to enable for trimming to fit variations in foundations, similar to what is currently done on roof trusses e.g. 25mm horn.
Lighter Weight
Gang-Nail Truss Frame elements weigh approximately 20% less than traditional timber frame wall panels as OSB is eliminated, and the panel is narrower. This makes them easier to manually handle and reduces overall transportation loads.
Benefits:
Eliminate OSB
Gang-Nail Truss Frame gains its structural strength and superior resistance to wind loading from the design and the use of Gang-Nail nail plates for the joints of the timbers. This eliminates the need for OSB, currently used to provide structural integrity to traditional timber frame walls. This means the elimination of panel nailing and OSB, and the associated use of synthetic resins and waxes.
Time Saving
Gang-Nail Truss Frame wall elements can as open panels be insulated with minimal cutting, reducing the on-site installation time.
Modular System
Gang-Nail Truss Frame is a set of standard wall panel elements (600mm, 1200mm, 1800mm, 2400mm wide and 2100-2700mm high) that can be combined multiple ways making it a modular system. It can form external, and internal load-bearing and non-loadbearing and party walls with no max span, allowing for wide open plan layouts and external apertures for large windows and doors. This offers true flexibility in design, whilst benefiting from standardisation efficiencies.
Integrated Wall Solution
The Gang-Nail Truss Frame elements are compatible with our Paslode and Cullen range. Paslode structural timber screws are used to fix the frame elements together whilst Cullen wall ties fix insulation and breather membrane as an integrated wall solution.
Produced Offsite
The Gang-Nail Truss Frame wall elements are designed to be made offsite, meaning they can be manufactured in a controlled environment. This helps meet the government’s pre-manufactured value (PMV) threshold of 55% for the Affordable Homes Programme.
NHBC Accepts Pending
Gang-Nail Truss Frame has been submitted to NHBC Accepts for accreditation. This means closed panels can quickly be inspected by NHBC in an offsite manufacturing environment and open panels equally quickly inspected on site, providing reassurance in compliance.
UKCA Mark
Gang-Nail Truss Frame is made as a finished wall element using Gang-Nail nail plates to press the timber joints together. As is currently a requirement in the production of roof trusses (BS-EN 14250), this means the wall elements can be UKCA marked by the fabricator. The presence of UKCA certification makes it easier and quicker to meet on site quality inspections and audits by TRADA, BBA, NHBC, etc.
Gang-Nail Plates
Chosen for its reliable quality and European compliance the Gang-Nail brand of punched metal plate connectors has been at the forefront of trussed rafter technology for over 50 years.
Benefits of Gang-Nail Plates:
Flexible
Suitable for a wide range of roof structures and building types.
Speed
Speed of construction allows just-in-time delivery to site.
Space Saving
No on-site storage area required.
Cost Saving
Prefabricated components mean reduced labour costs.
Efficient
More thermally efficient than alternative materials such as aluminium, steel or concrete.
SpaceJoist
Every new-built home is the result of extensive research and careful planning done by architects, engineers, developers and builders. SpaceJoist helps reduce the amount of time contractors spend on site, essentially speeding up construction and saving money without compromising safety. With this in mind, it’s not surprising to learn that SpaceJoist is growing in popularity within the construction industry.
At ITW Construction Products Offsite we believe in delivering the latest building technologies such as Gang-Nail’s SpaceJoist to offer more choice in cost and time effective solutions.
So, let’s take a closer look at why SpaceJoist is the most time and cost-effective choice for new build homes.
Benefits of SpaceJoist System:
Long Spans
Longer spans are achievable in comparison to traditional joist. 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 and reducing wastage 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 SpaceJoist system requires less construction material, saving cost.
Sound Performance
SpaceJoist delivers outstanding acoustic performance to comfortably surpass English and Welsh regulations, even complying with the more stringent 43dB Scottish regulations without additional insulation, plasterboard or resilient bars.
Fire Performance
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.
Precisely Engineered
SpaceJoist 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
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.
Loose SpaceRafter
SpaceRafter can be supplied loose for both residential and commercial builds. The rafters can be manufactured with rigid insulation between the timber chords for improved thermal efficiency.
Retrofit SpaceRafter
SpaceRafter combined with SpaceJoist can be used to create a room in the roof space by replacing the existing roof trusses. A detailed structural design and method statement must be prepared by a qualified designer before any work is undertaken.
Benefits of the SpaceRafter System:
Long Spans
Longer clear spans than solid timber can be achieved, requiring fewer intermediate supports, saving time on site.
Cassettes
Available in cassettes to increase construction speed on site.
