Internorm’s range of uPVC windows is also available with an aluminium cladding. These windows are named using the letters KF – the K stands for Kunststoff which is the German word for plastic, and the F is for Fenster, the German word for window. Where there are integrated blinds, the F is replaced with a V for Venetian which is Venezianisch in German.
The Internorm KF 220 window is available as uPVC only or uPVC with an aluminium cladding. The narrow, square-edged window frame gives the impression of fixed glazing but the window can be opened. The frame can be rendered on three sides for a frameless appearance. The glass pane is bonded giving all round excellent stability, thermal insulation and security.
The Internorm KF 500 tilt & turn window combines high performance with innovative design. It is available as a uPVC-only option or as uPVC/aluminium window. The square edged sash of the Internorm KF 500 sits behind the outer frame, creating a clean, contemporary look with maximum glass area and slim sight lines. The unique locking mechanism is fully integrated meaning the mechanisms are completely hidden when the window is open. When closed, levering of the window is impossible making it one of the most burglar-proof windows available.
Watch what happens when people attempt to break in to the KF 500!
Internorm’s KF 410 uPVC/aluminium composite window consists of a reinforced uPVC profile, highly thermally efficient insulating foam and a weatherproof aluminium cladding. The KF 410 is available in a wide selection of standard colours as well as a range of weather-resistant timber and metallic colour finishes. It is available in the Home and Studio ranges.
The combination of uPVC and aluminium in our Internorm KF 200 windows offers a high degree of functionality as well as excellent heat and sound insulation. The KF 200 is also available as a uPVC-only option.
Highly weather-resistant and virtually maintenance-free, the slim Internorm KF 200 window is a smart choice for your home.
The Internorm KV 240 window combines superior thermal insulation and sound reduction with integrated blinds. The blinds are fitted between the panes, protecting them from dirt and damage. Access to the blinds is easily achieved by simply opening up one of the hinged panes. The blinds are operated manually, or via a smartphone app – perfect for when you’re not at home, but want to appear to be.
The Internorm KV 440 window combines a flush design, high performance and integrated blinds. Cleaning the individual slats of the blinds is no longer necessary. The integrated blinds are fitted between the panes meaning they do not get dusty. If you need to access the blinds, an hinged single pane of glass can be opened. This is available with either an aluminium frame or glass edge (Studio range). The blinds can be operated manually, or via a smartphone app.
The HF range of Internorm windows offers the protection of aluminium on the outside, with the warmth of timber on the inside. The H is for Holz, the German word for wood. The F is for Fenster, the German word for window.
Enjoy the warmth and beauty of timber inside with the protection of aluminium outside, with the Internorm HF 210 Timber/Aluminium window. The square-edged aluminium profile can be designed in many colours and with endless design possibilities.
The Internorm HF 310 window is a combination of timber and aluminium, with a highly insulating thermal foam between the frame and sash. Natural timber and weather-resistant aluminium create a high performance window that is suitable for Passive House projects. The HF 310 window can be combined with the KF 410 uPVC window due to the same flush design of the aluminium cladding.
The Internorm HF 410 timber/aluminium composite window is a new development in the range and advancement in manufacturing technology. It features a laminated timber core and solid hardwood exterior, adding further strength and durability to these high performance triple glazed windows. The Internorm HF 410 is available in the Home Pure, Home Soft, Studio and Ambiente styles and in a range of wood finishes including Oak, Ash, Larch, Walnut and, for a vintage look, a new Grey Oak is now available.
