We make timber frame panels for your house or outbuilding and provide all structural calculations to satisfy Building Control requirements.
Our timber frames can be made using 140mm CLS timber or a double frame of 300mm thickness. All orders are supplied with all the fixtures and fittings needed to erect the house (including steel and glulam and anything else needed to create your home). And of course, we provide full Structural Engineering and detailed instructions to help you construct it.
The panel is made with minimum C16 timber with OSB/3 (structural oriented strand board) to one side which is covered with high performance (W1 suitable for Cornwall) breather membrane. This panel can then be insulated and if it is, this is covered with AVCL. The building is designed with walls at 600mm centres throughout - unless structural engineering specifies this differently - or our clients ask for closer centres.
The OSB/3 board has a little lip top and bottom to assist with the alignment of the panel to the sole plate at the bottom and to provide positioning for the headbinder across the top.
The breather membrane (Tyvek Reflex) has an excess to one edge to overlap onto the next frame when erected and ensure weather tight finish.
To assist with tying the frame to your external leaf (blockwork, carrier board, cladding - whatever you have chosen), we mark all vertical struts of the frame by stapling on a black tape
Each panel is clearly marked to match the layout plan provided so the puzzle is easy to follow
Structural internal walls are built using 140 0r 89mm x 38mm CLS timber, usually with 9mm OSB/3 to one face; whereas non structural walls are built using the same size and specification timbers but without OSB (unless they are needed as racking walls in which case they have OSB). Panels are designed with studs at 600mm centres to match the external walls and those without OSB have a half-way noggin
We are nearing the end our our development of a new double frame which will provide a 300mm wide wall with an insulated U value of up to 0.08 W/m2K. Exciting !
