Financing & Insurance Perks
- Lower structural load – HPL adds only ~12 kg/m²; lenders see less seismic risk and often accept thinner masonry reinforcement.
- Fire rating ready – Samrat boards hold a B-s1,d0 EN 13501-1 certificate, helping insurers shave 0.05–0.10 % off annual premiums for mid-rise housing blocks. linkedin.com
- Shorter build time – banks charge fewer interest days on construction loans when façades wrap up weeks earlier.
Together these trim another €6-8 / m² from the net-present cost.
