Structural insulated panels
are ideal for self builders wanting to achieve high-performing, energy-efficient homes. As their name suggests, SIPs
come pre-insulated to such high standards that, even without additional insulated liners, they can achieve U-values as low as 0.17 W/m²K. Adding suitable liners can get this number down to as low as 0.1 W/m²K.
support loads by their very nature as composite structural panels, and the boards are bonded to the insulation they sandwich to prevent buckling. This reduces the need for struts and supporting trusses, particularly where roofs are concerned, making them ideal for loft conversions.
SIPs are prefabricated in a controlled factory environment. The highly accurate cutting process allows for the fabrication of multiple identical panels, saving both time and money.
Where SIPs are slotted together, joining splines are used which virtually eliminate cold bridging and provide a high level of airtightness. The erection of a SIPs house can take 60% less time than a conventional timber frame.
