Profile Features

Glued Timber Layers

The core of the HF 400 system is comprised of multiple, ultra thin layers of timber that are glued together. This delivers a fantastic standard of durability and support, without the need for a chunkier or thicker profile.

Triple Gaskets

All Internorm window systems, including the HF 400 timber-aluminium profile, come with three continuous gaskets as standard. This ensures a comprehensive standard of weatherproofing, benefiting the end user massively.

I-tec Glazing

Modern I-tec Glazing will be fitted to the HF 400 timber-aluminium profile. It enhances light transfer by as much as 10% compared with standard glazing, while equally being incredibly durable and thermally retentive.

Versatile Application

The HF 400 system can be applied to a range of different windows, allowing them to suit all styles of property and a range of functions. The slimline design also aids itself well to balcony doors on multi storey commercial projects.

Handles

The HF 400 is fitted with secure handles that complement the sleek aesthetics of the Home Pure design. A range of options are available, allowing these windows to suit projects where enhanced security standards are required.

Internorm Handles

Glazing

Our Internorm I-tec Glazing can be frosted, toughened and otherwise upgraded in an array of different ways. Whether your commercial project is a set of new build houses or luxurious high-rise apartments, our glazing will be fit for purpose.
