Yes — we deliver within the United Kingdom. Delivery is quoted separately based on your postcode and site access.
No. Prices shown are per panel. Delivery costs are calculated separately once we have your postcode and access details.
U-value indicates how well the panel insulates — the lower the U-value, the better the thermal performance.
It depends on how the space will be used and your target performance. As a general rule, thicker insulation cores achieve lower U-values. If you share your project details, we can recommend a suitable specification.
Yes, panels can be trimmed and cut for openings, but we recommend planning layouts in advance to minimise waste and maintain performance.
Store panels flat, off the ground and protected from weather. Keep them covered and dry until they’re installed and fully weatherproofed.
Lead times vary by specification and workload. We’ll confirm the current production and delivery schedule when you place an order or request a quote.

Benefits of SIPs
Structural Insulated Panels (SIPs) are at the forefront of construction methods, and a key element to the future of the industry.
- Superior Thermal Performance
- High insulation values reduce heat loss and improve energy efficiency year-round.
- Faster Build Time
- Factory-cut panels significantly reduce on-site construction time.
- Structural Strength
- Engineered panels provide high load-bearing capacity and structural stability.
- Airtight Construction
- Reduced thermal bridging improves internal comfort and lowers energy costs.
- Precision Manufacturing
- CNC-cut panels ensure accurate fitting and reduced material waste.
- Energy & Cost Efficiency
- Lower labour time and improved insulation result in long-term savings.
