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.

Our energy-saving windows require minimal maintenance. Made from high-quality materials, they are resistant to warping, fading and rotting, ensuring long-term durability. A simple wipe-over with a damp cloth will keep your windows looking fresh for years to come.

Our energy-saving windows are designed to provide superior insulation and reduce heat loss, helping you create a more sustainable and comfortable living environment. With our triple glazed windows, you can enjoy improved thermal performance and lower energy consumption, leading to significant savings on your heating bills.

If you’re considering replacing your existing windows, our energy-saving windows are the perfect choice. Our windows are designed to minimise heat transfer, reduce draughts and eliminate cold spots, ensuring a more balanced living space all year round.

Our energy-saving windows are also durable against adverse weather and forced entry — they will not become damaged, warped or cracked when exposed to high temperatures or heavy rain, ensuring your Mirfield home remains draught-free year round.
