Vertical Sliding Sash Windows

SASH WINDOWS

uPVC Sash windows Northern Ireland.

Complement your home with our modern, elegant uPVC Sash Windows and you’ll be buying the very best because we go the extra mile to ensure you get the service you deserve, before, during and after installation. Our vertical sliding sash windows combine the beauty and class of the traditional sash timber window with the high performance, durability, security and energy efficiency of modern uPVC material, design and manufacturing techniques.

Our vertical sliders have both a slide and tilt opening facility. Both the top and bottom sash can be moved vertically and held in the required position meaning the sashes can be operated individually or simultaneously. And the tilt-in facility makes it easy to clean the frames and glass from inside your property.

Energy Efficiency.

Double glazed uPVC sash windows are often used as a replacement to timber in heritage properties as well as for new builds because they have hassle-free maintenance requirements, and glass with U-values of 1.4 w/m2K, and a WER “A” rating, which makes them one of the most energy-efficient windows on the market. Our windows come double glazed and triple glazed.

Bespoke Service.

Every Designer Door Company window is made to order, and with a classic white finish or an authentic grain-effect colour including black, oak, cream or whitegrain to choose from, you can add a personal touch that perfectly suits your property.
