Profile Features

I-tec SmartWindow Software

Controlling integral blinds has been revolutionised by Internorm. The KV 440 is compatible with our SmartWindow software, whereby the blinds can be controlled using an app, without any need for a power source, thanks to photovoltaic innovations.

Triple Gaskets

Internorm windows are fitted with triple gasket weatherseals, and the KV 440 uPVC-aluminium system is no exclusion to that. The end user will benefit from total weatherproofing and a phenomenal standard of air-tightness.

Ventilation Integration

In blocking out external light and enhancing thermal retention, it was integral that we fitted our KV 440 with our I-tec Ventilation. It ensures a consistent flow of air, preventing an excess build-up of heat and moisture, particularly during the warmer months.

Flush Fitting Profile

In-keeping with its sleek aesthetics, the KV 440 is designed with a fully flush profile, with a frame construction depth of 93mm. Flush fitting windows are fast becoming a popular in commercial use, thanks to their versatile and eye-catching visuals.


A choice of square edged handles are available for commercial applications of the KV 440. Secure and easy to operate for any end user, lockable handles and Secustik handles can add an extra layer of protection upon installation.
