The Leka Orangery roof system has been designed to be super lightweight so that it can be used to replace inefficient glazed or polycarbonate conservatory roofs. It uses glass reinforced plastic ring beam, ride and rafters for a system that’s 40 percent lighter than a typical orangery roof system.

Fully Approved Orangery Roof System for Quick & Easy Building Compliance

Just like the Leka Tiled Conservatory Roof, the Leka Orangery Roof has been fully approved by JHAI so installers can get building certificates fast.

The system, policies and installer training are assessed on a regular basis to ensure that structural details, condensation risk analysis reports and U-Value calculations are always up-to-date. Because the Leka Orangery System has been approved in this way, it should only be installed by a Leka certified installer.

Orangery Roof System Construction

Leka orangery roof is an innovative system that has been designed to be very lightweight and uses GRP to avoid any of the issues that come with aluminium and timber framed roof systems.

Glass-Reinforced Plastic Ringbeam, Ridge & rafters

  • Higher tensile strength than steel
  • No condensation like in aluminium products
  • No thermal bridging
  • No moisture absorption like in timber products
Leka External Boards
  • Alternative to plywood
  • Lighter than any other roof covering board
  • 100% waterproof
  • Thermally efficient
Leka Internal Boards
  • 100% waterproof
  • 1/3 of the weight of traditional plasterboard
  • Thermally efficient
  • Can be finished with traditional plaster skim ready for painting
  • Can be fitted with low-energy spotlights

How it Works…

 

  • Step 1 – GRP ring beam, ridge and rafters are fitted to existing or new conservatory
  • Step 2 – Insulated Celotex sheets are fitted with a 15mm gap between the sheets and the internal boards
  • Step 3 – Strong, insulating, load-bearing outer sheets are added to the roof
  • Step 4 – Waterproof coating ensures stylish finish and 100% weatherproofing
  • Step 5 – The glass roof lantern is fitted into place for the orangery effect
  • Step 6 – Optional guttering and fascias are installed
  • Step 7 – Internal Leka boards are installed ready for plastering
  • Step 8 – Low-energy spotlights can be installed and the roof can be skimmed
