Aluminium Windows, Doors and Conservatories

We offer aluminium windows, doors and conservatories for your home. Aluminium offers high quality weatherproofing, thermal efficiency and is durable yet lightweight.

Our aluminium windows, doors and conservatories also feature a polyamide thermal break, which allows our products to meet industry standards for energy efficiency with lower u-values, aiding in reducing the cost of your energy bills monthly.

Our aluminium windows, doors and conservatories also offer slimmer sightlines, allowing more natural light into your property and providing uninterrupted views.

Bifold Doors

Bifold doors have grown in popularity over the last few years due to their modern functionality and stunning aesthetics. Combining aluminium frames for additional security and strength, with high quality glazing, you will benefit from a secure home which performs with excellent thermal efficiency.

Create an uninterrupted flow from your house into your garden space with bifold doors, and improve accessibility due to low thresholds, making wheelchair access easier. Our bifold doors also come in a variety of configurations, and can feature up to 6 panels. You can also design your bifold doors to perfectly match your home, with a range of RAL colours and hardware options for you to choose from.

There is also an option to add integrated blinds to your bifold doors for low maintenance shading and privacy.

Sliding Doors

Sliding doors are ideal for homeowners looking to incorporate the outdoors within their home. With large panes of glass, you can benefit from uninterrupted views from your sliding doors. With slim sightlines and more glazing, you can gain an abundance of natural light.

Our aluminium sliding door design will also function well for years to come, as aluminium is unlikely to become warped, or rust during wet weather conditions. They also feature a polyamide thermal break that allows for dual colour systems and come with double or triple glazing. Our sliding doors also come in a range of colours, powder coats and finishes.

Aluminium Window Systems

We offer a wide range of aluminium windows for your home. Aluminium casement windows from Affix Windows are maintenance-free, thermally secure, feature multipoint locking systems and can be manufactured in a range of colours and matte finishes. 

Aluminium Flush Look windows offer a classic look with seamless, sleek sightlines for a broader view. Our flush windows sit flush within the window frame, offering an aesthetic with less bulk and a cleaner finish, making for a more appealing option for homeowners than traditional casement windows. These can be designed to be top or side hung, and open outwards. Our flush windows can also be designed with additional finishing touches such as teardrop, espagnolette and monkey tail handles, which come in a range of colours. 

Our tilt-and-turn windows combine sleek aesthetics and modern functionality. They provide excellent ventilation, as they can be kept in a vent position without security concern, and have a larger opening capacity. These windows are also customisable, and they can be fitted with your choice of hardware and designed in multiple colour options. 

We also offer stainless steel hardware. Our patio door handles provide a sleek, straight handle manufactured with marine-grade stainless steel. For our entrance doors, we offer a T-bar handle, which provides ease of installation and durability for everyday use. Our bifold or residential doors feature sleek straight lines and are fitted with dual springs, so they always return to 90 degrees. Our window hardware is a lockable espagnolette handle, which includes a sprung mechanism to keep the handle in place and a cranked design to prevent the handle from hitting against the frame.
