SIP House = 10K/W/M2

Thermal Performance
SIPS panels offer superior thermal performance.
PU cored SIP panels produce homes which are significantly more efficent.
Current building standards are 0.35/W/M2K, this translates roughly to an
energy requirement of 50Kw/hr/yr to heat a sq.m of floor area. SIP homes
will require significantly less than this, probably around 10Kw/hr/yr.
