Description

Britmet's Liteslate is an innovative synthetic slate roofing tile made from 90% recycled polymers with all the characteristics you can expect from a traditional slate tile. Offering an authentic finish with riven edges, traditional colour choices and impeccable durability.

 

During the design process, real Welsh slate was used to perfect the aesthetics and performance qualities of the Liteslate. However, unlike natural slate, Liteslate won’t crack, break, chip or delaminate due to its ground-breaking design and cutting-edge manufacturing process.

Furthermore, the Liteslate is designed with the environment in mind, using over 90% recycled polymers in the making of each slate. In 2021, Britmet recycled over three million kilograms of polypropylene during its manufacturing process.

 

Liteslate passed its fire testing with a BS476-3 Fire Rating. As Liteslate is compression moulded, it has detailed impressions displaying where to fix the slate, making it even easier for installation. It is also easy to cut, and only requires a sharp, fine-tooth saw or a sharp blade.
