All Year Round Living Space
TIMBER, ALUMINIUM OR STEEL?
Traditional materials all have their own individual risks and weight disadvantages. Timber will always retain a permanent moisture content, absorb moisture and be at risk of shrinkage, wood rot and decay.
Steel and Aluminium products are very good conductors, which leads to excessive heat transfer. Metal products also condensate a lot easier, leading to water droplets entering a roof space.
LEKA ROOF SYSTEM
The LEKA Orangery roof solves these issues by having an engineered design and fully composite layered system. Each individual layer is 100% water proof, weather proof, thermally efficient, lightweight and structurally tested.

LEKA Orangery Roof Breakdown
Below you will find a detailed system break down of the LEKA Orangery Roof System.
Step 1 – LEKA GRP Rafters
First, ‘Glass Reinforced Plastic’ rafters are added to your existing, or new orangery window frames, including a GRP structural upstand. GRP has a higher tensile strength than steel and is not prone to:
- Wood worm or rot (such as timber)
- Moisture absorption & expansion (such as timber)
- Condensation (such as aluminium or steel)
- Thermal bridging (such as aluminium or steel)
The beginning of your improved orangery roof insulation.
Step 2 – PIR Insulation
PIR high-grade insulation sheets are snugly fitted with a 15mm gap from the internal LEKA sheets. PIR is one of the UK’s leading insulation products, providing high value thermal efficiency and most insulation is BBA approved. This product is an added orangery roof insulation benefit that increases the roofs efficiency level.
ECO options of LEKA roofs are provided with EPS polystyrene. Please check with your installation company prior to purchase, to discuss your options.
Step 3 – LEKA External Boards
Next, strong, load-bearing and insulated outer sheets are added. These ensure less roofing bars and higher efficiency.
The LEKA external boards have been engineered to offer:
- A structural alternative to plywood or OSB
- A significantly lighter alternative to wood alternatives
- A 100% waterproof & weatherproof outer covering
- A thermally efficient board that promises results
The LEKA external boards are then covered with breathable membrane to add an additional weather proofing option.
Step 4 – Outer Weatherproof Coating
An outer weatherproof coating is then applied. This can be a choice of EPDM rubber or Fibreglass.
A stylish finish is created, ensuring your Orangery roof is the ultimate in watertight insulation that you can use all year round.

Step 5 – Glass Lantern
A glass lantern is then constructed onsite, adhering to installation guidelines supplied by the glass lantern manufacturer.
The glass lantern will allow light to flood through into the Orangery 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 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.
