Exclusive to Thermaglaze
Less frame, more light
The elegant, slim framework of our exclusive Slim Jim uPVC window system allows more light to flood into your home.
The ultra slim sightlines provide a much greater glass area than current standard casement windows and are perfectly suited to both modern and traditional houses.
Our exclusive Slim Jim window system is defined by its stunning ultra slim sightlines. Slender and elegant, they allow for a greater glass area and give a more refined look to a property – whether it is of traditional or contemporary design.
The increased glass area of our Slim Jim windows allows your room to be flooded with significantly more natural light, creating a warm and airy home environment for you and your family.
You’ll be amazed by the difference that the Silhouette’s slimmer frames can make to the ambience of your home.

You were able to offer us a slimline frame which matched the original windows and look more stylish than the thicker uPVC frames.
