Frequently Asked Questions

This is certainly common in smaller garden room type buildings in SIPs and technically possible in a full-scale house build also. SIP floors should always have a minimum of 50mm airflow gap below. The ground beneath SIP floor buildings should be graded with a permeable membrane and/or Type 1 MOT/gravel cover or alike. We also recommend treating the underside face of SIP floor panels with a bituminous primer prior to assembly.

No, services cannot be installed within SIP walls as they are thermally efficient and airtight. We recommend using a counter batten to create a service void for electrical wiring and fixtures. For external walls, services can be surface-mounted and boarded over. Internal walls are timber stud, allowing for standard service installations. Posi-Joists facilitate easy installation between floors.

SIP homes go up much faster than traditionally framed buildings. The nature of the panel system enables a fast-track building process which helps to reduce construction time. A typical two-storey 200m2 house takes approximately 10 days to fabricate in the factory and 15 days to erect on site.
