Orangery

Our orangery roof conversion kit replaces your existing fibreglass, traditional build, glass or polycarbonate roofing system with a lightweight, thermally efficient, structural Orangery roof system.

The ‘Leka Warm Roof System’ is approved by MFA, the licenced building inspector and is proven to outperform and outlast most other systems.

The orangery kit is designed for homeowners and built for the trade. It’s incredibly lightweight, easy to install and complies with building regulation U-values. There are no aluminium or timber components in the build, it is instead built from four simple ladder kits made from GRP (glass reinforced plastic).

If you’re looking to upgrade, replace or convert an orangery roof, our orangery roof conversion kit is up to 40% lighter than competitor products. It’s the cutting-edge roofing system of choice for many installation companies and homeowners because of this. When only the very best will do, Nautilus delivers.
