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

Our flush casement windows use insulated double glazing as standard and a precision-engineered window profile designed to retain heat, boost efficiency and reduce your energy usage.

Long Lasting Quality

Durable uPVC flush frames with a sleek, weatherproof design ensure long-lasting performance, giving your Yorkshire home enduring style with minimal maintenance.

Conservation Friendly

Flush casement windows combine classic timber-look joinery with modern design, offering woodgrain finishes ideal for conservation areas and heritage properties.

15 Year Guarantee

Our flush casement windows include a 15-year guarantee and require no upfront deposit – you only pay on completion of the works.

Enhance Your Home with Sleek & Timeless Flush Casement Windows

Flush casement windows are a beautiful blend of modern technology and classic design, perfect for Yorkshire homes. Because the sash sits flush within the frame, you get a sleeker profile that welcomes more natural light, gives a minimalist aesthetic and helps insulate your home. These windows recreate the look of traditional timber joinery, while being crafted from efficient, low-maintenance uPVC that offers excellent thermal performance without the maintenance associated with wooden windows.

Their smooth, symmetrical design enhances the character of any property, whether traditional or modern, giving your home instant kerb appeal and clearer views outside. And when you pair this heritage-inspired style with energy-efficient glazing and the latest security features, you enjoy a window that looks stunning while providing comfort and protection inside your home.

Features & Benefits

Discover the key features and benefits that make our flush sash windows a stylish, efficient and long-lasting upgrade for your Yorkshire home.

Conservation Friendly

With flush casement windows, you’ll be able to blend the innovative with the classic. These windows faithfully replicate timber joinery, and you can style them with woodgrain finishes too. That means these windows are ideal if your property is in a conservation area, as the contours of the design meet the requirements of most conservation officers.

Long Lasting Quality

Flush casement windows don’t only have timeless appeal. They can also perform for your Yorkshire home for more time than you might expect. With a durable uPVC frame and a sleek, weatherproof design, flush casement windows are an investment built to last. uPVC frames can perform at their peak for up to 30 years, even without regular maintenance.

Thermal Efficiency

Flush casement windows can update your home with the highest standards of thermal efficiency. Double glazing panes are designed to trap more heat inside your home and durable frames that reduce the gaps for cold air to enter it. The whole design works to preserve more heat, meaning you cut down your energy usage and save money.

Style and Security Combined

Flush sash windows sit neatly within the frame for a sleek, timeless look that suits both modern and traditional Yorkshire homes. You can tailor the design with a wide choice of RAL colours and finishes, all set on a strong internally beaded frame.

All flush windows come with high-security features as standard to help protect your home. They include premium multipoint telescopic locking systems, secure shootbolts and mushroom locking points, anti-crowbar hinge claw protection, and automatic key-locking handles. These features are designed to deliver strength, reliability, and complete peace of mind.
