A warm window of your home – a luxury, a waste of money, or a reasonable and well-considered choice?

The manufacturing of wooden windows requires not only great knowledge but also deep practical skills. Modern wooden windows are made of plywood beams of three, four or even five plies. Window beams are manufactured by means of the state-of-the-art manufacturing technologies by removing the defects of wood and concurrently maintaining its best qualities. Traditionally, pine wood is used for wooden windows. Also, windows can be made of mahogany, oak, eucalypt and other types of exotic timber. 

Wooden windows are noted for longevity, cosiness, excellent thermal and sound insulation characteristics; they excellently match furniture, doors and parquet of the interior. Wooden windows of good manufacturing quality will bring uniqueness, naturalness and solidness to your home.

 Advantages of natural wood:   

  • Low thermal conductivity
  • Low noise transmission
  • High resistance to cold
  • Low coefficient of longitudinal expansion
  • Environment-friendly
  • Attractive appearance
  • “Breathing” material
  • Does not accumulate electrostatic charge
  • Easy maintenance 

We offer you the following wooden window systems:

 

 

Euro 68 – windows that have ceased being very popular due to their unimpressive thermal performance. They are often installed in summerhouses, saunas and other premises that are not permanently occupied. The window offered by us is a “Soft line” product of the new design with more rounded inner edges. Due to that the window not only looks more visually attractive, but is also more durable. The window may be painted or varnished, and from the outside it can be additionally braced by aluminium.

Technical characteristics:

  • Heat transmission coefficient U=1.4W/(m2K)
  • Resistant to sound of 34db 
  • Resistant to 600 Pa water pressure

 

 

 

Euro 78 – 78mm thickness plywood windows noted for excellent thermal and sound insulation characteristics. These windows are especially popular among construction organisations where construction volumes are large and thermal characteristics of windows are subject to high requirements. As a rule, 42 mm thickness glass units are used. For greater protection against atmospheric impact, from the outside windows can be braced by aluminium.

Technical characteristics:

  • Heat transmission coefficient  U=1.1W/(m2K)
  • Resistant to sound of 36db
  • Resistant to 600 Pa water pressure

 

Euro 92 – the most state-of-the art 92 mm thickness heat-saving wooden window for your dwelling. This product is mainly preferred by customers in private houses who want to enjoy windows of maximum thermal performance. This window is manufactured of 92 mm thickness plywood beam of four of five plies of the selected type of wood. In order to ensure thermal performance of the window we use two types of glass units:

•56 mm triple insulated glass units. Heat transmission coefficient U=0.5 W/ (m2*K).

•60mm quadruple insulated glass units. Heat transmission coefficient U=0.37 W / (m2*K).

Total heat transmission coefficient of a window with a triple insulated glass unit, warm frame and selective coating of a new generation is U=0.81 W / (m2*K), and of a window with a quadruple insulated glass unit – U=0.73 W / (m2*K).

Glazing:

We install windows with triple or quadruple insulated glass units. Their thermal performance depends on the span between glass, inert gas filling such spans, special selective coating of glass and material of frames separating glass. As a rule, aluminium frames are used. “Termix” or “TGI” frames are installed in order achieve especially high thermal performance of the window. Thermal performance of glass units can be improved further by using krypton gas fill instead of argon gas between glass layers, but this is very expensive and, therefore, is seldom used.  A more popular method for improving the performance of a glass unit is to replace the usual selective coating by a new generation solution. To improve the stability of a window, glass units may be bonded inside the window frame. Total width of the insulated glass unit can vary between 24 and 60 mm. To bond an insulated glass unit into the window frame we use organic silicone or a special rubber gasket.

FAQ: 

 

 What is the coefficient “U” and what does it mean?

 The coefficient “U” is one of the most important parameters of the window, which shows the amount of heat that is released per square metre of a window per hour at 1 °C indoor and outdoor air temperature difference. The lower is heat transmission coefficient, the more effective is thermal insulation of the window and the lower is heat release to the outside. All “U” values are obtained through window testing. Tests are carried out with windows of standard parameters (1 230 mm*1 480 mm). Coefficients of windows of other parameters are values calculated by programme means.

What are the options of control?

  • Non-opening
  • Opening to the side
  • Opening to the side and tilting
  • Tilting
  • Folding
  • Casement-type
  • Pulling – sliding

What colours to choose and what can you recommend?

You can choose colours from “RAL” or “NCS” palettes. We recommend coating a wooden window from the exterior with paint and applying to the interior:

  • the same colour as that used for the exterior (most cost-efficient)
  • another colour from “RAL” or “NCS” palettes
  • a transparent varnish and retaining the natural colour of wood
  • a transparent varnish and creating the desired tint.

What are additional options of glass units?

Triple or quadruple insulated glass units are installed in windows. Their width ranges from 24 to 60 mm. To improve thermal performance of glass units warm frames “Termix” are used. Additionally available  options of glass units are: 

  • Solar control glass units
  • Self-cleaning glass units
  • Tinted glass units
  • Acoustic glass units (up to 52dB sound insulation)
  • Fire-resistant glass units (Ei30-Ei60)
  • Safety glass units (with toughened or laminated glazing)
  • Glass units with decorative glazing

Does aluminium cladding not damage the wood of a window?

Aluminium fitted in and installed correctly does not damage the wood and even provides maximum protection against undesirable exposure to atmospheric factors, while at the same time allowing the wood to “breathe”. Aluminium cladding screens are installed so as to keep it out of direct contact with the wood leaving a span for air to keep circulating. Such windows don’t require any special maintenance. The wood–aluminium window hardware used by is manufactured by the German company GUTMANN GmbH. We apply to aluminium profiles powder coating of any “RAL” colour or give it a silver tint by anodising.

What sizes of the European-type windows can you manufacture?

Depending on whether a window is of a casement-type or not, we can manufacture windows of the following sizes:

Casement-type window:

  • Min: 410 mm x 410 mm.
  • Max: 1100 mm x 2400 mm.
  • Non-opening window:
  • Min: 330 mm x 330 mm.
