Profile Features

I-Tec Core Innovation

Being a Timber-Aluminium profile, the HF 510 comes with our I-tec Core innovation as standard. The laminated layers of timber at the centre of the profile provide exceptional durability and robustness, enabling the manufacture of larger Timber-Aluminium composite windows as well as lift & slide doors.

Outstanding Acoustic Insulation

End users enjoy a better quality of life with Internorm triple-glazed windows, thanks to their inherent soundproof qualities. Decibel reduction levels of up to 43dB are achievable with the HF 510 profile, significantly blocking out external noise. Internorm windows and doors remain at the forefront of innovation.

Slim Frame

The HF 510 Timber-Aluminium composite windows and doors in design style Home Pure are engineered with a slim, modern profile, therefore benefiting from less frame and more glass. Not only does this improve the visual appeal of HF 510 windows and doors, but it also allows for more natural light transfer, improving quality of life and helping rooms feel brighter and more spacious.

Triple Gaskets as Standard

The HF 510 profile is fitted with triple gaskets as standard. These ensure complete weatherproofing, protecting against damp and rotting and providing improved air and water tightness. Combined with our I-tec Core’s resistance to humidity, these Timber-Aluminium windows and doors stand robust in even the harshest conditions.

Versatile Application

The HF 510 Timber-Aluminium tilt & turn windows and doors are made to the client’s specification and are available as single or double openers, as well as balcony doors, can be fitted with Juliet balconies and combined with large lift & slide doors, as well as our HV 450 window with integrated blinds.
