Extreme Window & Door Collections

The perfect blend of style and security.

There are several reasons why our customers choose our window and door range, most notable the unique designs, impenetrable security and unrivalled value for money. The purpose-crafted UPVC profile that’s used across the entire Extreme window range creates a classic design that can be made to suit any home. Your family will remain safe with our state-of-the-art security features and a selection of highly efficient glazing options helps to ensure your home remains fully energy efficient.

Extreme UPVC Windows & Doors


The supremely adaptable Extreme window collection has been created to suit any existing home décor. Sleek, sturdy frames achieve a truly minimalistic look, offering much the same features as traditional timber. A more technologically advanced range of windows you will not find.

Choose from our modern casement window or opt for the tilt and turn range for unlimited adaptability and versatility.
