Timber-Aluminium Windows

Efficiency Meets Longevity

Internorm’s timber-aluminium windows offer the warmth of natural wood inside, paired with a durable aluminium cladding on the outside. This combination protects the timber from weathering while providing a sleek, modern finish.

The space between the materials is filled with high-performance foam, delivering excellent thermal insulation and helping to reduce energy bills. Available in a range of colour and finish options, these windows can be customised to suit both modern and period properties.

If you’re looking for a cosy, elegant finish with long-term performance, Internorm timber-aluminium windows are a perfect choice.

Energy Efficiency with I-tec Innovation

Thermally Efficient Windows

All Internorm window systems are built for thermal efficiency. With triple glazing and innovative I-tec insulation technology, these windows help reduce heat loss and improve energy performance, making your home more comfortable while lowering your heating costs.

Whether you choose timber-aluminium or uPVC, you can be confident that Internorm products meet and exceed modern energy standards.

Internorm uPVC Windows

Stylish, Secure and Low Maintenance

Internorm’s uPVC window range is ideal for homeowners seeking an affordable, low-maintenance window solution without compromising on quality. These windows are customisable in shape, size and style to suit your property.

Internorm uPVC windows feature I-tec Glazing, which bonds the glass pane securely to the frame for enhanced security, soundproofing and insulation. This improves not only the window’s stability but also its overall energy performance – helping to create a quieter, warmer home.

With their sleek finish, robust design and affordability, uPVC Internorm windows are a smart investment for both new builds and renovations.
