The 125mm panel is our thinnest variation of SIP. Consisting of two layers of 11mm OSB and a layer of 97mm EPS, the 125mm SIPs are ideal for constructing small garden buildings, SIP floors or party walls.
They are available in standard lengths of 2.4m, 2.7m & 5.1m and we can cut these to bespoke lengths.
For panel to panel connections, a 97mm x 90mm insulated spline should be used. Insulated splines prevent cold bridging and offer unmatched air-tightness, ensuring that your SIP building provides high thermal performance.
