Below you will find a detailed system break down of the Leka Orangery Roof. This provides lighter and better conservatory roof insulation. We will explain how the only roof system of its kind in the world can transform your existing conservatory or enhance your proposed new conservatory project.
Step 1 - GRP Rafters
First, 'Glass Reinforced Plastic' rafters are added to your existing conservatory window frames, including a GRP structural ring beam, rafters and ridge. GRP is not prone to:
- wood worm
- moisture absorption such as traditional timber
- thermal bridging such as bulky Aluminium alternatives.
The beginning of your improved conservatory roof insulation.
Step 2 - Celotex Insulation
Insulated Celotex sheets are snugly fitted with a 15mm gap from the internal Leka sheets. Celotex is one of the UK's leading insulation specialists, providing high value thermal efficiency and BBA certified and a significant benefit in achieving a better conservatory roof insulation efficiency level.
Step 3 - Outer Sheets
Next, strong, load-bearing and insulated outer sheets are added. These ensure less roofing bars and higher efficiency.
Our Leka outer boards have been engineered to offer:
- A structural alternative to plywood
- A significantly lighter alternative to any other roof covering board
- A 100% waterproof outer covering
- A thermally efficient board
Step 4 - Outer Weatherproof Coating
An outer weatherproof coating is then applied by your installation company.
This will provide final waterproofing along with a stylish finish, ensuring that your conservatory roof is the ultimate in watertight insulation.
Step 5 - Glass Lantern
A glass lantern is then lowered onto the current structure and fixed into place by your installer.
The glass lantern will allow light to flood through into the conservatory and provide an elegant looking finish.
Step 6 - Fascias and Guttering
UPVC fascias and cappit are now attached onto the edges of the structure.
This then allows guttering to also be attached onto the UPVC fascias cappit as an optional step.
Step 7 - Internal Leka Boards
Next, internal Leka sheets are added underneath the GRP rafters. The Leka sheets are 100% waterproof and one third the weight of plasterboard.
These sheets have unique thermal qualities as well, but allow for a traditional plaster skim finish to provide a nice visual aspect ready for painting afterwards.
Step 8 - Internal Plaster
The underside of the roof then has a high quality, traditional skim plaster finish applied.
Low energy spotlights can then also be fitted for the best possible interior lighting.
