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.
