HV450

Our Internorm HV450 Timber/aluminium windows with integrated blinds are available from Thames Valley Windows throughout Berkshire, Surrey, Hampshire, and the Southeast.

The Internorm HV 450 window combines a sleek, flush design with high-performance, integrated blinds, offering innovative performance in a single unit that protects against solar glare, heat loss, noise, and unwanted views.

The HV 450 offers a clean, modern aesthetic, with outstanding thermal, acoustic and security performance.

The integrated sun and privacy protection blinds, such as Venetian, Roman or Duette blinds, are fitted between the panes, meaning they do not collect dust. If you need to access the blinds, a single pane of glass can be opened.

This is available with an aluminium frame or glass edge (Studio range). The blinds can be operated manually or via a smartphone or tablet.
