uPVC casement windows that perfectly mimic timber

As well as giving your home or building that extra level of curb appeal, Residence’s uPVC casement windows are being accepted into more and more conservation areas. They provide a charming and unique look to traditional and modern styles, homes and buildings.

They offer:

– excellent energy efficiency properties
– high durability with a lifetime guarantee
– security features that meet British Standards
– an exciting selection of wood grain finishes and colours

You won’t need to worry about fading, flaking or tarnishing either. And uPVC makes maintenance easy.

Your window your choice

If you want your casement window to be triple glazed instead of double (which is standard), you can add it. If you want your handles to be gold, silver, graphite, or in a quirky shape, you can. If you require Georgian bars or want coloured or leaded glass—you can have that too.

No matter what features you’re looking to give you window that individual touch, we can help you.

The Residence Collection

The Residence Collection was all designed in Gloucestershire at their HQ, then extruded in Wiltshire.

Their timber alternative windows, including the Residence 9, extract the key principles, shapes and dimensions from the Article 4 Conservation Area guidelines for windows and integrate market-leading technology into the design using virtually maintenance-free materials.

They now continue to add more flush window & door systems based on their knowledge and expertise of the market.

We’ve been supplying and installing their products for a while. And their timber alternative frames have left customers in awe. The design is so close to the original, from the curb, you can’t tell the difference.

Established in 1970, John Fredericks Plastics have now amassed 50 years of trading with a strong record of innovation and a loyal customer base.
