The other advantage with this method is that it eliminates the need for dealing with risk associated with fire-during-construction– the product is enclosed with non-combustible boards.
Stick building is simply the construction of a timber frame on site utilising loose timber. It is a flexible system that avoids the need to pre-fabricate panels in a factory and is therefore cheaper, easier and quicker to procure.
We have a specialist timber frame design engineer who provides us with the design and, as part of our service, carries out site inspection of the installation to check conformity with the design and standard detailing.
We don’t believe that SIP panels offer best value for money. Our frames are cheaper and easier to procure, yet can still achieve the necessary insulation values.
A frame’s sole purpose, after all, is to hold the building up; it isn’t on display, so why pay more?
We don’t believe that it is. We believe that off-site manufacture leads to compromises due to forming unnatural joints between panels. It’s very difficult to lap around corners or overlap fire protection boards when you have pre-manufactured panels.
Our experience is also that factory manufacturing doesn’t account for building tolerances. Often panels are altered on site to accommodate substructures which, whilst within site tolerances, mean the panels won’t fit.
We practise strict quality control with the materials that we use, the designs that we produce and site quality audits.
All of the structural timber that we use is treated with preservatives (Vac-Vac).
When stick-building we fit the boarding to the structure last, after the frame is up, and immediately fit the breather membrane. This means that the boarding is not subject to weather for long periods of time. Prefabricated panels have the external boards fitted in the factory and the boarding is therefore exposed to weather throughout the construction of the frame.
We believe that our system gives many programme advantages:
Stick-built frames will generally be 10-15% cheaper than prefabricated frames, because:
Timber is a sustainable resource and will assist anyone looking to achieve highly in BREEAM or the Code for Sustainable Homes. We believe that stick-building introduces a lower carbon footprint by not transporting material to and from a factory. Timber comes loose and is sourced locally to the site resulting in far fewer delivery miles.
Stick building also uses less timber as we don’t need to double up on studs to close panels, as a panel fabricator would. Subsequently we produce less waste and generally find we can use off-cuts for noggins and other site practices.
