Tips for SIPs

Clean simple designs work best.

Maximise the opportunity for a healthy indoor environment.

Install a heat recovery ventilation system - using a bypass heat exchanger. 


Use full panels wherever possible, or easy fractions of panels (1/2, 1/3, 1/4).

Work within standard panel heights of 2.44, 2.74, 3.0, 6.1 for most effective use of panels. All panels are 1.22 wide.

Minimise the size of heating/cooling units.

Allow for the much greater insulation capabilities of SIPs.
