Concealed sash, visible effect

The MB-70 concealed sash system is a part of a door-and-window system with MB-70 thermal barrier by ALUPROF S.A. The window sashes made of elements of this system are invisible from the outside which increases the aesthetic values of the product. In a series of opened and fixed windows, the appearance of all sashes is identical.

The width of the window frames is small, that’s why the structure seems to be slim and light. Just like in the standard solution, the MB-70 system windows are equipped with an effective ventilation and drain system to remove water from the pane chamber and from the chamber between the sash and frame. The ventilation and drainage holes are covered with plastic shields on the outside.

System with increased thermal insulation

In terms of design, the MB-70 US is a solution identical to the MB-60US system construction. The difference lies in thermal insulation – in the case of the MB-70 US system, the Uf heat transfer coefficient is from 1.35 to 2.16 W/m2K (depending on used profiles and accessories).

Anti-burglary constructions may be constructed on the basis of this system.

One system, many possibilities

MB-70(HI) Casement outwards-opened window system with thermal barrier is a part of the MB-70 system. It works out perfectly in case of exterior architectural elements such as different types of outwards-opened fixed windows, vestibules, display windows or spatial structures characterised by good thermal and sound insulation as well as water and air tightness. This system meets all requirements concerning energy saving and environmental protection and all strict standards and regulations.

What makes the MB-70 (HI) Casement system exceptional?

• The constructional depth of profiles is 70 mm (window frame), 79 mm (sash).
  Such depths of the frame and sash profiles make the widow look from inside as one surface after it is closed.
• Three-chamber profile construction, where the central insulation chamber is located between thermal inserts, with a width of 34 mm,
• Possibility of obtaining two construction variants varying in thermal without the need to change the basic profiles and accessories. The first variant (MB-70 Casement) with empty central chamber inside the profiles interconnected between the thermal inserts is characterised by the lowest thermal insulation. The second variant of windows (MB-70HI Casement) with central chamber filled with a special insulating insert is characterised by a high insulation,
• A high water and air tightness and good thermal insulation possible to obtain thanks to among others special shapes of two-component central gasket (with cellular insulation part), as well as rebate and glass gaskets.
• Most gaskets (e.g. glass gasket and outer gasket) are installed continuously, without cutting at the corners, joining the gasket ends at mid length of the upper horizontal transoms. The central gasket is cut at the angle of 45°, it is glued in the corners or at the angle of 90° and glued to the rubber corner. A central gasket in form of vulcanised frame is also available. Such a way of gaskets mounting ensures a very good water and air tightness,
• Wide range of possible glass thickness: frame – from 14.5 to 53.5 mm, sash – from 23.5 to 62 mm. Wide glazing range allows to mount all types of one-chamber, two-chamber, soundproof and anti-burglary glasses available on the market,
• The use of typical Euro-type hardware grooves enables mounting of available hardware for both outwards-opened aluminium windows and plastic windows. Profiles without grooves in casings are intended for use with scissor hinges.
• It’s possible to use scissor hinges (invisible) or traditional pivot hinges (visible) in these windows,
• The drainage of the profiles may be executed in two versions: concealed or visible with decorative plug.
• The MB-70 (HI) Casement is compatible with other Aluprof systems, in particular with MB-60, MB-70. Thanks to that, many elements can be used in more than one system, e.g. glazing beads, gaskets or hardware.
