Secure and Durable Double Glazing

If you’re looking to replace your uPVC windows, composite doors and aluminium bi-fold doors, then you can benefit from fantastic security. Whatever choice you make, you can be sure that your family and home will be well protected.

Our composite doors feature an inner timber core to strengthen the profile of the door, making our composite door range virtually indestructible. In addition to this the replica timber appearance is finished with a GRP (Glass Reinforced Plastic) coating, for extra strength.

The uPVC selection of windows and doors are tightly extruded to offer an improved weather seal and robust operation. There are also designed to be resilient to force entry, ensuring our customers benefit from high-security and durability, which will give you peace of mind.

Aluminium double glazing is inherently strong, with our premium aluminium products from Aluk building on this. The top quality materials combined with an intelligent design offer homeowners in Sutton an incredible level of security.

All our double glazing comes with a highly-secure locking mechanism integrated as standard. Optional high-quality hardware, such as handles and hinges that are designed with security in mind, further enhances the protection of your home and prevents leverage.

Thermally-Efficient uPVC Double Glazing

Our high-quality double glazing uses innovative technologies to improve energy ratings and better circulate your home with heat. For instance, our uPVC double glazing features a four chambered design that allows windows and doors to achieve WER A+, without triple glazing.

Our top of the range Aluk aluminium profiles provide low conductivity of heat, much like its counterparts uPVC, meaning double glazing achieves low U-values and optimises thermal-efficiency. Aluminium doors are incredibly weatherproof, providing a rigid, weather tight frame that performs under pressure.

Composite doors are incredibly thermally-efficient, offering a cosy temperature for your home with its thick, heat retentive skin. Our composite door collections from Solidor and Door Stop are thoroughly weather resistant, providing extensive protection against cold draughts and wet or stormy weather.

We have a great selection of uPVC windows and doors, which are completely weather-proof due to their plastic coating and tight weather sealed profile. Alaskan Windows provides fantastic double glazing options in Sutton that are thermally-efficient, which means you can save money on energy bills shortly after installation.

Innovative Manufacturing Processes

Our high-calibre of products undergo an innovative manufacturing process whereby the latest machinery and techniques are utilised. Our products are low maintenance, as they are designed to be corrosion and weather resistant, which means they will never rot, wear, fade or require repainting.

The manufacturing process features a number of highly-innovative tools including twin-strand extruders and a 3D printer that make up part of the sophisticated fabrication process. Meanwhile, the Aluk aluminium profile is manufactured using 100% recycled aluminium, using 95% less energy in the process.

Composite doors are manufactured to the highest-standard, utilising environmentally-friendly, high-quality materials such as uPVC. We use a mixture of materials to mediate between timber doors and uPVC ones, offering the same aesthetics, with less impact on the earth’s environment.
