We've created Energy Performance Specification sheets showing suggested configurations for achieving the best U-values and energy ratings. These downloadable resources are available in the Related Downloads section of each relevant product, and can also be accessed using the search function in the Resources section of the website. Existing Liniar customers can access these documents along with our Energy Performance Handbook in the Vault section of Liniar Connect.

Liniar designs and tests products, extrudes the PVCu profiles and delivers them to independent specialist manufacturers and resellers all over the UK. You can find your nearest with a simple postcode search.
