Why Proven Energy Performance Matters

Choosing which windows and doors to buy for your home can be difficult. From choosing the right style and colour to selected products that are in-keeping with your property takes a lot of consideration and guidance, all of which Martindale Windows can help with. However, whilst the choices for the right style of windows and doors can be tricky, lnowing how energy efficient they are couldn’t be simpler.

Don’t listen to unsubstantiated claims about energy performance. The BFRC ‘rainbow’ label is proof your windows and doors will perform as promised and will provide the optimum levels for your property. Accept nothing less. As standard, all Windows and Doors that we supply to customers throughout Northamptonshire and beyond are certified to the BFRC rating and are independently verified by experts for their ability to insulate your home. Discover more about what this can do for your families energy efficiency below.

Benefits of BRFC Rated WINDOWS & DOORS

Lower ENERGy Bills

With a clean, consistent and slim design, our bi-folding doors superbly reflect the care with which they were made, with frames that can be powder coated in vivid colours on either side.

Improved Home Comfort

These beautiful frames are highly durable, with narrow profiles and glazing seals hidden within the frame, meaning more glass to help you enjoy more of the outside world.

Cut Carbon Emissions

Korniche bi-folding doors exude the same quality in their function as they do in design, with an exclusive roller system that delivers an effortlessly smooth glide every time.
