SIPs Technology

SIPs (Structural Insulated Panels) have been in use since the 1930s when they were invented in America in an effort to use timber more efficiently. Since those first houses were built SIP technology has come a long way and has become an established industry in America with some 42 million square feet of SIP panels being built in the US in 2009. The market share of SIPs in the US has grown in each of the past 5 years versus other forms of construction and has been used in Europe, especially Northern Europe, far longer than in the UK due to greater emphasis on keeping the cold outside.

Since SIPs were introduced to the UK in the 1980s, they have gone from strength to strength, with thousands of SIP houses now built in the UK due to their excellent energy efficiency and strength.

Sound Performance
SIPs eco panels can be used as a party wall achieving up to 59db reduction (45db requirement by building control, with 25mm mineral wool and plasterboard plank to either side)

Fire Performance
Class 1 – The standard finish for interior walls and ceilings is dry lining using one layer of 12.5mm Lafarge plasterboard with fire-tape on the joints.
Class 0 – The optimum fire rating is achieved using two layers of 12.5mm Lafarge plasterboard.
(Refer to Construction Manual for full details)

Roof design

Recommended roof design is carried out by a structural engineer where necessary.

Foundation to wall detail

Sole plates are fixed to the slab by means of mechanical fixings at specified centers. The sole pate is treated softwood with the width dependent on the thickness of the panel core.

*When used with a 60mm clear cavity and 100mm brickwork.
All panels are also available in widths of 300mm and 600mm.
All panels can be cut to suit or extended in length to suit requirements.
All panels are supplied with a reflective breather membrane as standard to improve thermal efficiency of the cavity.
All panels can be used for either wall, or roof panels, subject to design and loads.
