What are SIPs?
Structural insulated panels are composite building elements typically formed from an insulating core bonded between structural facings. Used together with timber splines, plates, beams and connections, they create insulated walls and roofs.
Key customer benefits
Rapid shell construction
Panels arrive cut to size, reducing wet trades and site fabrication.
Thermal performance
Insulation is integrated into the structure, helping create a continuous thermal envelope.
Airtight construction
Designed junctions and sealed panel connections can support good airtightness when installed carefully.
Design flexibility
Openings, roof forms and finishes can be tailored to a wide range of architectural styles.
Technical considerations
Good SIP construction depends on complete design, moisture control, ventilation, fire detailing, correct foundations and careful installation. Performance should be demonstrated for the specific panel system and project rather than assumed from generic claims.
SIPs compared with traditional construction
SIPs can reduce the time needed to form an insulated shell and may simplify coordination. Traditional masonry can offer different benefits relating to supply chains, familiarity and thermal mass. The right choice depends on design, location, programme and procurement priorities.
