FORMA windows

We present the FORMA window line, which will soon be available in the offer of MS beyond WINDOWS. The products are distinguished not only by their construction and modern design, but also by the presence of the latest Siegenia TITAN AF hardware. A noteworthy solution is, among others, sash flush with the frame and summer-winter night vent.

Time for a new standard and pure form

We are introducing three unique product concepts for sale: FORMA, FORMA Viso and FORMA ThermoFibra. They are based on the innovative solutions of the Belgian company Deceuninck. This brand has been producing PVC profiles for windows for over 80 years, combining unique technologies with modern design. Thanks to this, the new line of FORMA windows is a response to the needs and expectations of our customers. Additionally, the presented products open up new opportunities for architects, thus changing the perception of PVC windows for the next decades.

Framing the future

The new line of FORMA windows is primarily:

• minimalistic PVC window concept;
• very good parameters – thermal insulation, strength and tightness;
• traditional design with bold, straight profile edges;
• sash 80 mm deep based on a 76 mm frame. The assembly height (frame+sash) is only 112 mm (in MSline+ assemly height is 123 mm);
• additional central gasket in the MD frame;
• heat transfer coefficient of assembly sash/frame U_f = 1.0 W/m²K (in the case of the FORMA basic sash);
• 50 veneers to choose from (more than in products based on Salamander profiles).

Characteristics:

• very narrow rebates in the frame and in the sash and straight edges of profiles and glazing beads;
• the presence of a closed reinforcement with a thickness of 2 mm in the frame;
• new Siegenia hardware with extensive standard equipment e.g. hinges with a load capacity of 130 kg and modern steel security striker plates with composite inserts and rollers facilitating putting the sash into the frame;
• the possibility of equipping windows in innovative summer-winter night vent. This element allows the amount of air entering the interior to be adjusted to the conditions prevailing outside;
• coloured windows welded in V-Perfect technology using modern Graf Synergy robots;
• the system belongs to the 76 mm group, however – due to the fact that the depth of the basic sash is 80 mm – not fully suited to this classification.
  

The following video shows the functioning of the latest hardware.

Modernist design of the FORMA Viso window

Forma Viso is a bold extension of FORMA windows with a design sash with a depth of 92 mm, which is completely flush with the frame from the outside. It enables the construction of double-sash windows and balconies with an extremely narrow flying mullion – only 124 mm wide. Heat transfer coefficient of assembly sash/frame U_f = 1.0 W/m²K.

FORMA ThermoFibra – glass fiber reinforced sash

FORMA ThermoFibra is the most advanced composite technology in PVC windows. A sash with a depth of 85 mm is reinforced with glass fiber. This effect is obtained as a result of the process of linctruction, i.e. coextrusion of the profile and the glass fiber strands. Thanks to it, it is possible to achieve the appropriate stiffness of the cross-section without the need to use steel reinforcements. The effect of this technology is a very low heat transfer coefficient of the sash/frame assembly U_f = 0.88 W/m²K.

Comparison of new windows with the system MSline+ (AD and MD) and MSline can be found in the table below:

One frame – many possibilities

The newest products in the MS beyond WINDOWS offer are constructed using a 76 mm deep frame. It does not mean, however, that in this situation we are dealing with the standard 76 mm system. In each of the presented variants, a sash with a different depth is used. The profiles used consist of seven chambers, thanks to which they are characterized by very good thermal insulation. In the case of FORMA windows, the sash depth is 80 mm. In turn, for FORMA Viso windows, this dimension reaches the value of 92 mm. FORMA ThermoFibra products are made with the use of sashes with a depth of 85 mm.

Smaller assembly width – more world

Extremely narrow sash rebate

Due to the use of an innovative method of profile reinforcement, very good thermal insulation properties of ThermoFibra windows could be achieved with a assembly height of only 109 mm. These products are distinguished by an extremely narrow rebate in the sash (7 mm wide). Until now, such a parameter could only be obtained in aluminium systems. From the outside, the glass is practically flush with the sash profile. It is worth noting that FORMA window profile systems have received prestigious awards for their unique design e.g. reddot, German design award special and TOP Builder. Deceuninck was also a laureate of the Innovative Solutions for the Joinery Industry program. The jury awarded the IRBS Quality Mark to the ThermoFibra technology, consisting in the reinforcement of the window profile with glass fiber.

Prices for the new FORMA window line

We assume that the price of FORMA windows (with a sash 80 mm deep) in the MD version (with a middle gasket) will be equal to the cost of MSline+ AD windows (without a middle gasket). The offer will include a balcony sash and a terrace sash that opens outwards. We do not exclude the possibility of introducing a special promotion on a new line of windows. In turn, FORMA Viso windows (with a flush sash 92 mm deep) will be priced as products from the series Wood Look/ ALU LOOK. However, it will not be possible to use a balcony sash, arches and slants. We are currently working on preparing the FORMA ThermoFibra system for production in terms of technology.
