Features

Premium Performance, Naturally Beautiful Inside

The HV 450 is one of Internorm's most refined offerings – pairing the natural warmth of timber with integrated shading technology that takes care of your home's comfort without you ever having to think about it.

Integrated Blinds Between the Glass

Sun protection and privacy blinds sit between the accessible inner glass panes – shielded from wind, rain, and dust entirely. A refinement that genuinely improves everyday life.

Automatic Solar Control

An optional photovoltaic module and built-in sensors automatically control the integrated shading – no power source required, no manual adjustment needed on a bright summer morning.

Natural Timber Interior

Available in oak, spruce, larch, ash, or walnut, the interior timber finish can be chosen to complement your home's interior scheme – a personal, characterful touch that no synthetic material can replicate.

Maximum Sound & Thermal Insulation

With U-values as low as 0.62 W/m²K and sound reduction of up to 47 dB, the HV 450 offers outstanding performance across every measure that makes a home more comfortable.

Three Design Styles

Available in three distinct styles, the HV 450 integrates into a range of architectural settings and can be combined with other Internorm window systems for a coherent overall appearance.

Substantially Reduced Maintenance

Because the integrated blinds are fully enclosed between glass panes, they are protected from all dust and weather – significantly reducing cleaning and upkeep compared to conventional external shading.

Colours

Timbers and Colours That Are Yours to Choose

The Premium Timber Aluminium Window That Thinks Ahead

The HV 450 is the window you choose when you've thought carefully about what you want your home to feel like – and decided that comfort, calm, and quality are non-negotiable. The integrated blinds, tucked between the glass panes and impervious to weather, mean there's simply less to worry about. Less to adjust, less to clean, less to maintain.

The optional automatic solar control takes that thinking one step further – using sensors and a self-powered photovoltaic module to manage the shading for you, keeping your rooms at a comfortable temperature without any effort on your part. In a home that deserves the best, the HV 450 quietly delivers it.
