Pitched roof sip construction.

Extreme s pre insulated sips offer an option for a high performance roof framing solution that is 15 times tighter than conventional construction practices making it easier to control indoor air environment. Robin is working on an extension so we thought we d shadow him for the day and see how he creates a pitched roof or semi pitched roof leading up to a flat. Want to learn more about extreme s sip roofs. Although there is no single standard roof pitch used on all sloped roofs factors such as roofing materials and local climate help to determine the appropriate range of pitches for a given building.

Prefabricated trusses which are delivered to site and erected. Roof pitch is a measurement of a roof s slope expressed as a ratio. A traditional method of cutting timber on site and building up the roof using rafters joists purlins ridge boards etc. A job using numerous 8 x 13 panels will be much more expensive than one using 8 x 12 panels.

The speed of construction offered by jumbo panels has resulted in the 8 x 24 size osb becoming the sip industry standard. When the house was built melton sealed the seams between roof panels with tape applied on the bottom of the panels. The top of the roof was completely covered in a peel and stick membrane. Typically composed of a layer of eps expanded polystyrene xps extruded polystyrene or polyurethane foam sandwiched between oriented strand board panels sips can provide r values for walls floors and roofs ranging from 14 to 58 depending on panel thickness and composition.

The cost of a sip project is partially dictated by the number of 8 x 24 sheets that are required. In both cases melton now says the seams of the tape and the roofing membrane didn t seem to stick very well. The standard 8 x 24 sip size is determined by availability of jumbo osb. There are also a number of other framed constructions such as portal frame roofs.

With regards to the pitch the building standard code bs 5534 recommends a minimum pitch of 20 0 for slate roofs.
