HV 450

The HV 450 is a unique timber/aluminium profile, which comes with Internorm’s stunning integral sun protection hardware as standard. It retains many of the core characteristics of an Internorm profile, delivering eye catching aesthetics and offering versatile application.

With an array of benefits and an even wider range of customisation possibilities, the HV 450 is a fantastic option for all commercial projects. However, they are a particularly excellent option for larger, multi-storey complexes where sun protection is of higher priority.

Profile Features

Integrated Sun Protection

The HV 450 utilises Internorm’s I-tec Shading system, a market leading integral blind. Available in a range of designs, they operate with an energy efficient photovoltaic module. I-tec shading helps maintain a consistent room temperature.

Concealed Hardware

Components, such as locking systems and batteries, are all discreetly fitted into the HV 450. By concealing the hardware, the visual appeal of the flush timber-aluminium profile can be maintained, while still achieving great performance levels.

Flush Profile

The HV 450 timber-aluminium profile is designed to be fully flush, utilising our Studio styling. The flush sash perfectly complements the design of timber and integral sun protection, further enhancing visual appeal.

Triple Gaskets

The HV 450 system makes use of Internorm’s unique triple gaskets. Three continuous weatherseals are fitted around the perimeter of the flush sash, protecting internal components during more adverse conditions.


Internorm Studio windows and doors are fitted with square edged, straight line handles as standard. Doing so ensures consistently sleek aesthetics throughout. We have a range of security handles for the HV 450, as well.

Internorm Handles
