Frequently Asked Questions – EPS & XPS Boards 2025/2026
Which board gives the best U-value?
Graphite EPS λ=0.031 – 160 mm achieves 0.18 W/m²K on 215 mm solid brick.
Do I need XPS below DPC?
Yes – XPS has <1 % water absorption and 300 kPa strength. EPS is not suitable below DPC.
What thickness do I need for Part L 2025?
100–120 mm basic compliance · 160–200 mm graphite EPS for maximum savings & future-proofing.
Are boards fire-rated?
Both achieve B-s1,d0 in full certified EWI system. Mineral wool required for A1/A2 rating.
Can I cut boards on site?
Yes – hot-wire cutter or fine-tooth handsaw. Minimal dust with graphite EPS.
