Transform your orangery with a Leka warm roof system
Leka is the perfect roof for your Orangery
Whether you are building a new Orangery style extension or upgrading your conservatory to create a contemporary living space – the Leka Orangery Roof System provides a high insulated, lightweight solution.
Lightweight and strong design
The Leka orangery roof system is up to 40% lighter than a typical orangery roof construction. This means that you don’t have to add cost to your project by adding extra strengthening or reinforcement. The unique Leka orangery roof is also much faster to install, so your new or refurbished orangery can be built in just days, not weeks.
Better insulation, better looking
The Leka orangery roof has been designed as a super lightweight system so that it can be used to replace inefficient old glazed roofs. Its strength comes from Glass Reinforced Plastic ladder rafters and Celotex insulation boards to provide a high level of insulation. The Leka system achieves a significant improvement on thermal efficiency without thick insulation mats that require a deep and unsightly fascia board to hide them.
A light, airy extension to your home
A glass lantern light creates a stunning centrepiece to your new Leka orangery roof refurbishment or extension. It floods the room with light, adding elegance and height to provide an airy space that feels extra spacious.
The ceiling that surrounds the lantern light can be finished with a traditional plaster skim and fitted with low energy downlighting.
