PvC Windows

We offer many different PvC window options and finishes available to suit all home and tastes. Our PvC windows are now made to such a high standard that they have been recommended in conservation areas that have historically been solely timber.

PvC window styles

2800 White uPVC open window


Our Casement window is our most popular window available in two styles – an ornate finish to match traditional timber windows, or a straight bevel for a more modern ‘clean line’ look.

This range can be upgraded to our infinity range which would enhance the look of any window but particularly the colours and wood grains.


Infinity Casement

We have recently been able to offer our Infinity Casement range which takes our traditional Casement window and enhances it in three main ways

1. Visually – corner joints are almost invisible

2. Strength – the way the window is jointed creates a much stronger window 

3. Equal glass lines – due to the way the window is made the glass and frames are always symmetrical and even.

Infinity Flush

The Infinity Flush range looks very similar to the Residence 9 range externally and has a narrower ornate detail internally. 

It is designed to be a replacement window for 70mm windows which is the most common on the market. 

This window comes as standard with the infinity finish which creates stronger and better looking product.


Residence 9​

Our Residence 9 collection is specifically designed to be an alternative to traditional timber windows. 

The profile is 100mm deep and so would also fit a proper triple glazed glass unit which achieves the best thermal ratings. 

All windows in this range are flush externally with a deep ornate detail internally. The outer frames are always mechanically jointed with the sashes having the option of mechanical joints or upgraded to our infinity finish.

Arched Sliding Sash

Sliding Sash

A more traditional window which is deeper than casements. 

Our ranges of sliding sash have many options including a tilt function for easy cleaning, run through horns to look more like timber and new finishes which even experts have mistaken the window for actual timber!
