Reviews
Thank you to the installers Joe and Luke for their hard work. It wasn't easy going up all the stairs but they were happy doing so and I couldn't be happier with the doors. Also Henry has been fantastic from start
Glideline installed 6 sets of sliding doors in our house. This was a major investment for us so we wanted it to be just right. David and all the team were friendly and helpful from start to finish. Henry was great.
FAQs
How much do your windows cost?
Glideline don’t believe in a one size fits all pricing strategy. We make all of our aluminium products on a case by case basis, and we price in the same way so that the pricing suits the individual specifics.
Are aluminium windows thermally efficient?
Our frameless windows use a thermally broken fixing system which will help keep your home as energy efficient as possible. This could potentially lower your reliance on central heating as well as bills.
Are they long lasting?
Our aluminium windows are extremely long lasting and hard wearing, offering great resistance to the elements. With our ten year guarantee, you’re ensured a decade of high aluminium window performance.
