Liniar Upvc Profile.


The newest brand of PVCu frames on the market, Liniar was created by bringing together some of the window industrys most experienced and forward thinking designers with over 500 years of industry experience between them.




With a focus on research, development and design, Liniar continues to push the boundaries when it comes to product innovation. You can buy other windows that are energy efficient. You can buy other windows that are secure. The Liniar range is different because we've significantly reduced the need for steel reinforcement to make a window that gives you all of these features in one, without additional modifications. For example, we were the first to introduce a fully bespoke PVCu bi-fold door in the UK. This has already proved a serious alternative to aluminium or timber bi-folds, with higher energy efficiency and lower maintenance costs.




And our clever low-threshold door option makes our doors family friendly whilst also facilitating wheelchair access. Available in a heavy duty gold or silver anodized finish, we also designed the doors with hidden rollers so they look better too. We also know that when you build a glazed extension such as an orangery or conservatory, you want it to match your windows and doors. Thats why our roofs are available in exactly the same style and colour options as the rest of the Liniar range. Embedded in Liniars culture is an ethos of constant innovation and development, which means Liniar customers always have access to the most forward-thinking products in the industry.



The underlying objective of Customer care carried out within Alternative Windows will continue to be aimed at maintaining an environment in which everyone employed and associated with the Company perceives themselves as purveyors of quality.
