Types of Windows and Glazing

We provide a wide range of products and offer durable, long-lasting window systems that meet your individual needs.

Our wooden window systems:

Euro 68 – these are windows that are no longer very popular due to their poor thermal properties. They are usually used for saunas, summer cottages, or other non-residential premises. The windows we offer are a re-designed “soft line” product, with more rounded inner edges. This makes the window more attractive, and also more durable. The window can be painted or varnished, and the outside of the window can also be clad with aluminium.

Technical characteristics:

  • Heat transfer coefficient (U-value) = 1.4 W/(m2K)
  • Sound insulation 34 dB
  • Water tight at 600Pa

euro78Euro 78 – these are 78 mm thick glued timber windows with very good thermal and acoustic insulation properties. These windows are particularly popular with building organisations, where construction volumes are high and the thermal properties of the windows are subject to strict requirements. Double-glazed 42-mm units are usually used for these windows. For better protection against weathering, the windows can be clad with aluminium on the outside.

Technical characteristics:

  • Heat transfer coefficient (U-value) = 1.1 W/(m2K)
  • Sound insulation 36 dB
  • Water tight at 600Pa

euro92Euro 92 – this is our newest 92-mm wooden window that will help you save heat. Customers tend to choose this product for private homes, where they want their windows to be as warm as possible. The window is made of 92-mm glued laminated timber engineered from four or five layers of the wood of your choice. We use two types of insulating glass units to ensure that the window stays warm:

  • 56-mm triple-glazed unit. Thermal conductivity coefficient (U-value) = 0.5 W/(m2*K).
  • 60-mm quadruple-glazed unit. Thermal conductivity coefficient (U-value) = 0.37 W/(m2*K).
  • The total thermal conductivity coefficient of a window with a triple-glazed unit, a warm frame and new-generation low-E coating is U = 0.76 W/(m2*K), or U = 0.67 W/(m2*K) for a window with a quadruple-glazed unit. (Declared U-values are for windows that measure 1230 mm x 1480 mm and have Soudatherm SFI 600P polyurethane foam between the insulating glass unit and the frame.)


We install double-, triple-, or quadruple-glazed units in the windows. Their thermal properties depend on the gap between the panes of glass, the inert gas in those gaps, the special low emissivity coating applied to the glass, and the material that the frame holding the glass is made of. Aluminium frames are the most commonly used. Frames from Termix, TGI or other manufacturers are used when maximum warmth is a priority. The thermal properties of the insulating glass unit can be further improved by replacing the argon between the panes of glass with krypton, but this is uncommon due to the high cost. A more common way to improve the properties of the unit is to use new-generation low emissivity coating instead of conventional low-E. The total thickness of the insulating glass unit can be anywhere from 24 to 60 mm. We seal the insulating glass unit in the window frame with environmentally friendly silicone or use a special rubber gasket. To enhance the stability of the window, the insulating glass unit can be glued into the window frame. For this we use Soudatherm SFI 600P polyurethane adhesive.

Advantages of Soudatherm SFI 600P:

  • Improves airtightness (EN 1026/EN 12207)
  • Improves the Uf-value of the window, resulting in very low thermal conductivity: 0.036 W/mK
  • The product is a good sound insulator
  • Thanks to its excellent adhesive properties, it improves the mechanical stability of the window
  • No combustible materials
  • No solvents
  • Once it dries completely, it is flexible, not brittle
