Energy Efficient Double Glazing

Marathon Windows supply made to measure energy efficient uPVC Double Glazed Windows, Front Doors and Conservatories. All of our double glazing products are tailor made, assuring that your products are installed perfectly.

Did you know that 10% of energy from your home escapes through ill fitted windows and doors? Professionally fitted double glazing is a sensible investment, it helps drastically reduce heat loss from your house. If you’re looking to reduce cold spots, save money and reduce your carbon footprint then be sure to view our range of glazed windows and doors in Coulsdon.

Double Glazing works by trapping a layer of air between two panes of glass. The trapped air prevents cold air from entering your property and stops your heating from leaving your house. The gap between the two panes of glass is too tight for the air to begin circulating, helping to create a thermally efficient barrier.

For added security, we offer a variety of upgrades. Security handles, hinges and advanced security hardware to tenfold the protection that the unit uPVC Window or Door offers.

In addition to our locks, our double glazing profiles are extremely robust and provide your home with the security you need.
