Quality Finishes

The most advanced and refined windows and doors on the market, every StyleLine profile has an impeccable finish, with the highest attention made to quality and detail. You can expect an immaculate colour and finish to the sash and outerframe, making them very different to your average window.


Thanks to a revolutionary welding process these uPVC windows are extremely weather tight. This unique welding process results in a stronger and more resistant frame which is why they are far more secure and energy efficient than standard windows.
