Three Benefits of Choosing uPVC Sliding Sash Windows

uPVC sliding sash windows look stunning and perform across all important criteria. Discover the many advantages of choosing this design over others.

uPVC sliding sash windows are vertically operated. Because they don’t open inward, objects can be placed near to the installation. This style of window offers incredible convenience underscored by equally incredible looks.

Homeowners can keep their property safe, due to the industry-leading security hardware used in our windows. Even without upgrading, they’ll be able to enjoy high standards of performance that meet industry specifications but can also upgrade to a Secured by Design specification.

Our uPVC sliding sash windows won’t let the cold in. The thermal technology included in each profile includes weather seals and hidden gaskets that repel wind and rain, resulting in a watertight design that will make the home in question warmer and a more pleasant place to spend time in.
