LEKA LANTERN LADDER SYSTEM

HIGH QUALITY, QUICK TIME

STEP 1 -  GRP RAFTERS

First, 'Glass Reinforced Plastic' rafters are added to your existing, Orangery window frames, including a GRP structural ring beam, rafters and ridge. GRP is not prone to:

• wood worm

• moisture absorption such as traditional timber

• condensation

• thermal bridging such as bulky Aluminium alternatives.

The beginning of your improved Orangery roof 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 Orangery and provide an elegant looking finish.

STEP 4 - OUTER WEATHER PROOFING

An outer weatherproof coating is then applied by your installation company.
This will provide final waterproofing along with a stylish finish, ensuring that your Orangery roof is the ultimate in watertight insulation.

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:

1. A structural alternative to plywood

2. A significantly lighter alternative to any other roof covering board

3. A 100% waterproof outer covering

4. A thermally efficient board

STEP 2 - CELOTEXT 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 Orangery, roof insulation efficiency level.
