Ease of installation

Window Warehouse added the Leka Warm Roof and Leka Orangery Roof to its portfolio in January 2017.

Malcom Cake, managing director of Window Warehouse, said: “We chose Leka Systems because the products offered something different. They have a lower U-value so outperform other roofing options. There was a unique selling point because there was no use of timber or aluminium unlike other systems.”

More than 50 Window Warehouse installers have been trained and become Leka-certified installers. Installers rate the ease of installation and the quality of the initial training session.

They also appreciate the lightweight system which suits retro-fit projects.

Window Warehouse has developed a retail-focused website, which has been designed to generate enquiries to pass on to approved installers.
