Why not opt for aluminium?

Aluminium bi-fold doors share many of the benefits of uPVC, but often to a higher degree. They are extremely durable, resistant to warping from heat, and are powder-coated to ensure the finish lasts for decades to come.

Aluminium doors are often made with thinner frames, allowing even more light to pass through. We have a range of designs and colours to choose from, including wood-effect for that traditional feel.


Couldn’t fault Cosy Warmth Windows from the start to finish, Paul and his team were brilliant. Would highly recommend them to friends and family!


Had all our windows replaced and delighted. One of a few companies we found that would replace single windows too.

Great fit and finish

We have used this company twice and have been more than happy each time. Very professional and friendly but most importantly the installed doors and windows were of very high quality with great fit and finish.

They also install plastics for soffits, fascias and guttering so they will be getting another call from me later this year.
