Internorm KF310 aluminium clad uPVC, Triple Glazed Composite Windows, Semi-Detached House, London

Location: London
As part of this home renovation, we replaced wooden leaded windows with high-performance Internorm KF310 triple-glazed composite windows to create a comfortable, low-energy home.

The London property is on a popular tree-lined avenue near the beautiful Richmond Park.

Before starting their home renovation project, the London homeowners visited Grand Design Live for inspiration, and they stopped by the Internorm stand to view their range of double-glazed and triple-glazed composite windows.

The client was keen to replace their tired wooden windows with a more modern glazing solution that was low maintenance and offered high-performance thermal efficiency, acoustic and airtightness but would also complement the traditional aesthetics of their London property.

Our Architectural Project designer, Marcus, contacted the London homeowners to discuss their home renovation project; he listened carefully to their brief and window design requirements. They wanted to reduce their environmental impact while also improving the functionality of their property.

The project would be completed in two phases. The first phase was to replace four west-facing leaded windows at the front of the house.

The second phase would be to replace the east-facing windows at the rear of the property.

The London homeowners had already decided on the high-performance Internorm KF310 uPVC/Aluminium windows. Marcus worked with the homeowners to supply and install a complete glazing solution throughout the semi-detached property.

To ensure that the new triple-glazed composite windows met their exact specifications, Marcus designed them with precision and attention to detail to preserve traditional aesthetics while embracing modernity. This also included flying mullions to the three-pane bay windows.

The aluminium-clad uPVC triple-glazed composite windows are finished in traffic white on the exterior and Edelweiss on the interior; the finishing touch is the brass handles.

The four triple-glazed composite windows at the front of the property have been designed with a 9mm lead detail to match the existing and include curved lead in the front bay windows.

All the windows at the rear of the property have clear triple-glazed panes of glass, and three of them have pull-down fly screens.

Internorm is one the leading European manufacturers of premium composite triple-glazed windows and doors that far exceed the new building regulations requirements.

The KF310 uPVC/Aluminium window is a sleek slim-line window with rounded edges and manufactured with a construction depth of 74 mm that is both aesthetically pleasing and functional. Three continuous gaskets provide properties with thermal insulation and sound reduction and have a positive effect on rain and air tightness.

The new 6-chamber frame profile enhances the property’s energy efficiency and thermal performance and will help to reduce energy bills and CO2 emissions and support a more sustainable future.

uPVC is a weather-resistant material like aluminium and is inherently robust and sturdy. However, combined with the excellent insulation values of uPVC window frames and the longevity, durability and weather resistance of aluminium, the Internorm KF310 is a highly innovative window solution that will provide your property with thermal comfort, sound reduction, and security.

The KF310 uPVC/Aluminium window improves heat retention and can reach thermal insulation up to 0,69 W/(m²K) and Sound reduction up to 33 – 45 dB, suitable for low-energy homes. They are available in a wide variety of different colours and glazing options to suit your home improvement or new build project.

Internorm offers a range of composite windows, including the popular aluminium and timber clad. Double and triple-glazed units use Low-E glass, are filled with argon gas, and have warm edge spacer bars to minimise heat loss.

This triple-glazed composite window installation demonstrates Internorm and our commitment to quality, precision, and sustainable design solutions. It has provided London homeowners with a beautiful and functional investment that enhances their quality of life.

The exterior powder-coated aluminium cladding provides long-term durability, excellent protection against weathering and corrosion, and added security against burglaries. In contrast, the uPVC interior provides clean aesthetics to the interior decor.

The London homeowners are delighted with their triple-glazed windows, which have helped reduce noise pollution and maximise natural daylight, providing a comfortable and quieter living environment. They have advised:

The triple-glazed composite window installation was very well performed: skills, communications and professionalism of the TVW team. We decided to go for phase 2, aiming to replace all the windows. The end result was very good, and it was a good investment.

The London homeowners also gave us a glowing 5-star Trustpilot review and lovely feedback
