Leka System — Trade Supply

Leka Orangery
Roof Kits

Complete orangery conversion kits — strip out glass, polycarbonate or dated fibreglass and replace it with a lightweight tiled warm roof. U-values from 0.10.

The Detail

A Clear, Practical Upgrade
For Orangery Installations

Built on the patented Leka GRP framework to BS EN13706, with U-values from 0.10 and a finished weight close to the glass being replaced. Keep the glass lantern for height and daylight, or specify optional LEKA Skylites.

GRP rafters with Celotex insulation eliminate the cold-bridge at the ring beam that plagues timber and aluminium hybrids — no rot, no swelling, and a ceiling ready for plaster skim and low-energy downlights.

Genius engineering: four simple ladder kits meet building regulation U-values off the shelf, every component is two-person handleable, and the roof is weather-tight in days. Proven across a network of over 10,000 completed Leka installations.
