Market-leading products based on your specifications.
Our aluminium windows are a great way of bringing your Harpenden home into the modern age. These slimline profiles incorporate large areas of glazing, providing you with panoramic views of your Hertfordshire home. We supply and install the Alitherm 300 and Alitherm 600 profiles from Smart Architectural Aluminium, a market-leading profile that will offer you the highest levels of quality.
Aluminium as a material is renowned for being rigid and more secure than uPVC. With our aluminium windows, you’ll enjoy the best security and a great thermal performance. Although aluminium previously faltered for the thermal performance, our aluminium windows are manufactured with a polyamide thermal bridge. This will trap in pockets of warm air to provide a comfortable temperature within your Harpenden home throughout the year.
To ensure that we take advantage of the solidity of aluminium, we offer the finest locks. The Harpenden homeowner can enjoy high-quality multi-point locking mechanisms from Yale. This means you and your family can sleep peacefully knowing you have the best protection.
At Kingsbourne Windows and Doors, we appreciate that every Harpenden home is different. That’s why we supply and install a range of aluminium window styles, to offer something for every Hertfordshire property. Whether your home is traditional, contemporary, heritage or modern, we’ll find a window that fits.
Each of our aluminium windows can be customised to fit all your specifications. We offer a selection of RAL colours, which are applied through powder coating. This means even after exposure to the changeable Harpenden weather, your window will retain its quality look. These colours will never fade or require repainting.
We install a range of aluminium window styles. They include aluminium casement windows, French casement windows, tilt and turn windows, sliding sash windows, flush sash windows, and Crittal replacement windows. Each one can be customised through a variety of window hardware and glazing. You’ll enjoy a range of handles, hinge finishes and stops, providing you with a truly bespoke finish for your window.
Unlike uPVC, aluminium is quite sturdy. This means our aluminium windows can have slimmer frames without straining under the weight of the glazing. With larger areas of glazing, you’ll enjoy unobstructed views, flooding your home with light.
Through offering the Yale locking system in our aluminium windows, you can enjoy the complete peace of mind that your property has the best protection. Yale locks are tamper-proof. The quality is so good, they are accompanied with a 10-year guarantee and £1,000 insurance, covering your home if there is a break-in caused by a faulty lock.
Unlike the steel and timber windows our aluminium profile seeks to emulate, you won’t be left with the same high maintenance headaches. These aluminium windows are manufactured from the finest aluminium and won’t warp, rust, bow, twist, rot, decay or discolour. The only maintenance the homeowner needs to carry out on their window is to give it an occasional wipe with a damp cloth. Thermally Efficient
We give you aluminium windows that help keep your home warm and dry. The polyamide bridge and the superior gaskets we install mean that your windows will stop the heat from escaping and prevent ingress of draughts and rainwater. Your Dunstable home will be more comfortable even with lower energy usage.
