Our CL3 Triple Glazed Range and other triple glazed windows are subject to size restrictions and style limitations due to the weight of the glass – see your
representative for details. The maximum size for any triple glazed glass unit is 1.7m2

due to health & safety reasons. Where a required unit size is larger, an A-
rated double-glazed unit will be supplied and installed.

“Self-cleaning” glass is not a ‘100% maintenance-free’ product but does offer a reduced need for manual cleaning.

*New windows from Coral could save our customers hundreds of pounds on their heating bills*
You can check both your potential savings on heating costs and your CO2 savings by entering a few simple details into our energy calculator which can be found
on our website https://www.coralwindows.co.uk
As an example, a typical customer (living in a semi-detached house which has wooden single glazed windows and mains gas heating) could save approx. £911 on
their heating bill over the course of the first 12 months after they had new double-glazed windows installed by Coral Windows (information correct as at
13/10/2023). Potential savings will vary depending on the information entered into the energy calculator.

Thermal Efficiency

By adding an additional pane of glass, triple glazed windows offer a remarkable improvement in thermal performance. This means lower heating bills and a warmer home environment during those chilly Yorkshire winters.

Noise Reduction

Live near a busy street or noisy area? Triple glazed windows are excellent at reducing sounds from outside, allowing you a quieter, more peaceful living space.

Home Security

The additional layer of glass in triple glazed windows makes them tougher and more difficult to break, providing an extra level of security compared to double glazed units.

15 Year Guarantee

At Coral Windows, all of our home improvements come with a 15-year guarantee, giving our customers complete peace of mind that they are investing in quality.
