Services
Double Glazing
Our double glazing solutions use A+ rated glass to trap heat indoors, reducing energy bills and carbon footprints. The sealed units feature argon gas and high-density insulation for superior thermal efficiency. Ideal for homeowners seeking cost-effective, eco-friendly upgrades, this service enhances comfort year-round while maintaining security with robust locking systems.
Conservatory Roofs
Transform your conservatory with solid or lantern roofs designed for year-round use. These installations improve thermal performance, eliminating cold spots and draughts. The lightweight yet durable materials ensure structural integrity while allowing natural light. Perfect for extending living spaces without compromising on style or energy efficiency.
Timber Windows
Crafted from sustainably sourced hardwood, our timber windows combine traditional aesthetics with modern security features. Internally beaded glass and multi-point locks deter intruders, while low-maintenance finishes resist warping. Available in dual-colour options, they suit heritage and contemporary properties alike, offering thermal efficiency and timeless elegance.
Aluminium Bi-Fold Doors
Aluminium bi-fold doors provide sleek, space-saving access to gardens with slim sightlines and weatherproof seals. The multi-point locking system ensures security, while thermal breaks reduce heat loss.

Report
We have recently worked with Insulating Windows and had all of our windows replaced. The service and attention to detail was fantastic. They are such a great company to deal with. Grant & Liz on the sales side listened to what we wanted and went away and sourced the exact wood-effect casement windows in our chosen colour. They visited the house many times to give us ideas too. We were given sample windows to try out at home and also went to the showroom to discuss options.
Once we made a decision the turnaround was fast, professional and slick. The team of guys who fitted the windows were punctual, tidy, professional plus really polite and friendly. The windows look amazing and we are absolutley delighted! The price was the best compared to all the other quotes we had had! I would 100% recommend Insulating Windows to anyone looking to replace their windows and doors. We actually missed the team when the job was finished! Thanks All! - you are the best!

I highly recommend Insulating Windows. I've recently had windows and French doors installed and from beginning to end of the transaction they were professional, prompt, completed an excellent job and their customer service was first class. Thank you. I wish your company continued success
