Heritage Windows

Our range of Heritage windows are the latest breakthrough in window technology. Identifying that many homeowners throughout the North East wanted the slim lines and styling of timber windows but also the durability, security and energy efficiency of UPVC, Pennine now offer Heritage windows. Our Heritage windows have been designed to replicate traditional 19th Century flush sash timber windows. But by using UPVC rather than timber, Heritage windows will never rot or warp and require very little maintenance.


Fully sculptured, contemporary or traditional - the choice is yours...

What puts most people off the idea of purchasing timber-based home products is the continuous preservation of the wood necessary to ward off the threat of rotting and fading. Pennine has a solution in the form of our Heritage range which possesses all the looks and hallmarks of wood, such as the window sash sitting flush with the frame, but requires zero maintenance. It also offers several other modern benefits such as outstanding thermal insulation and security, qualities that the traditional timber fell down on. It’s a fantastic option for those struggling to source an authentic window replacement in a conservation area.
