PIR
PIR uses the same OSB sandwich render as EPS — we do not have a separate PIR photo. The badge is the difference. Not included in the panel price: timber joining splines, fixings, structural design, building control, install. More than 10 SIP panels? Trade rates or WhatsApp. Need joining splines? See below.
Joining splines
Supply accessory for recessed SIP panel edges. 2.44 m timber joining inserts sized to the core. Live eBay list (Sep 2026) — can change. Not included in panel or shell-kit prices. Count and core confirmed on the quote.
| Item | Length | sipsonline (live eBay) |
|---|---|---|
| SIP97 joining spline | 2.44 m timber insert | £11.00 |
| SIP122 joining spline | 2.44 m timber insert | £12.00 |
| SIP147 joining spline | 2.44 m timber insert | £13.00 |
Match the spline to the SIP panel core thickness you are joining. Fixings and structural design still separate. Shell kits are walls + roof SIP panels only — add splines if you want them on the same drop.
