Wooden windows

Wooden windows are a very important part of the house – not only do they add to the aesthetic appearance, but they also enhance thermal insulation, building envelope airtightness, acoustics, reliable opening and closing, security and, of course, a cosy atmosphere.

With extensive experience, we know that it is wood that provides the best thermal and acoustic insulation properties as well as longevity and durability. Unlike plastic or aluminium, wood experiences very little longitudinal deformation, i.e. as the temperature changes, both plastic and aluminium lengthen or shorten, and as this cycle repeats, they lose their shape and twist, making the windows less airtight. Of course, wood also has its caprices. It absorbs moisture, which affects its dimensions and thickness. However, neither moisture nor temperature has a major effect on the longitudinal dimension of wood. Modern wood painting technology allows maximum protection of the product from moisture absorption, and provides the wood with maximum protection against UV rays, which destroys the surface of the wood. Glued laminated timber is used in production to increase the stability of the wooden windows. This consists of three, four, or sometimes even five layers of parallel timber laminations bonded into one beam. The outer layer of the beam must be cut radially and cannot have any longitudinal bonding joints. Wooden windows made of properly prepared glued laminated timber are extremely stable and durable.

We offer our customers two types of high-quality wooden windows that are made to order using the latest technologies.

European-style wooden windows

European-style wooden windows are produced from natural wood – usually pine, but sometimes oak, mahogany, eucalyptus or exotic wood as well. These wooden windows give the home a classic, timeless aesthetic while also ensuring warmth and airtightness.

Euro 68 – these are durable, attractive wooden windows that are usually used for saunas, summer cottages, or other non-residential premises.

Euro 78 – these are double-glazed 42-mm wooden windows with very good thermal and acoustic insulation properties.

Euro 92 – these are one of the best wooden windows ensuring warmth and airtightness, and are usually used for private homes with the highest thermal insulation requirements.

Scandinavian-style wooden windows

Scandinavian-style wooden windows are modern, practical outward-opening windows that easily find a place in even the most complex architectural solutions. Scandinavian-style wooden windows are easy to distinguish: they have a smaller frame and more glass. The windows are lighter, durable, and look modern.

We make these windows from mahogany, oak, larch, knotty pine or knot-free pine.

Useful information

  • knot-free pine
  • knotty pine
  • larch
  • oak
  • mahogany

You can choose from RAL or NCS colours. We recommend using paint for the outside part of a wooden window, but the inside part can be:

  • finished with the same colour as the outside of the window (most economical),
  • finished with another RAL or NCS colour,
  • finished with a clear varnish that shows off the wood’s natural colour,
  • finished with a varnish that gives the window the desired shade,
  • oiled.

We install double- or triple-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. Termix or TGI frames are used when maximum warmth is a priority. The total thickness of the insulating glass unit can be anywhere from 24 to 56 mm. Most manufacturers do not use insulating glass units thicker than 46 mm, claiming that anything more does not improve the thermal properties, and that the optimum thickness for the frame holding the glass is 16–18 mm. They are absolutely right, but nowadays, the vast majority of homes have at least a few large windows where the glass cannot be 4 mm thick. The larger the window, the thicker the glass has to be. This is necessary to ensure that the glass does not crack due to its size and weight. Of course, as the glass gets thicker, the frame gets thinner in order to maintain the same overall thickness, so when a huge unit has three 8-mm panes of glass, the units we produce will still have 16-mm gaps, but if the unit is thinner, then the window will definitely not retain heat as well.

NEW: the gap between the insulating glass unit and the window frame is sprayed with special sealing foam. This gives the window:

even more airtightness, because air can no longer freely move around in the space behind the glazing strip

better acoustic insulation because once glued, the insulating glass unit transmits less vibration

better thermal values, since the perimeter around the unit is the coldest part of the window

better window stability, because the insulating glass unit is glued in and serves as a diagonal to prevent the window from “sinking”

  • Thermal and acoustic insulating glass units
  • Solar control glass units
  • Self-cleaning insulating glass units
  • Tinted insulating glass units
  • Acoustic insulating glass units (sound insulation up to 52 dB)
  • Fire-resistant insulating glass units (Ei30–Ei60)
  • Safety insulating glass units (with tempered or laminated glass)
  • Insulating glass units with decorative glass

Decorative grilles are often used to divide the window into smaller panes. There are different types of grilles:

Aluminium grilles are usually used when the outside of the window is covered with aluminium cladding.

Wooden grilles can be fastened in two ways:

By glueing them to the insulating glass unit with double-sided tape and sealing them with clear silicone.

By attaching them with special holders so they can be removed if required.

Grilles inside the insulated glass glazing unit.

In order for the grilles to divide the unit into smaller panes nicely and for the sections to look like separate units, inner bars are inserted inside the insulating glass unit under the grilles.

In the manufacture of warm, Scandinavian-style windows, weight is often a problem. Triple-glazed units can be very heavy, so for flawless operation, we use fittings from the Danish company PN UNI, which are the strongest and highest load-bearing in the market.

Handles can be:

  • standard,
  • with a button,
  • with a button and a key.

Aluminium cladding on the outside of the window provides the wood with maximum protection from adverse atmospheric factors while also allowing it to breathe. These windows require no special maintenance. The aluminium profiles can be powder-coated in any colour from the RAL palette, but we also have the unique ability to cover the aluminium with a faux wood finish. The corners of the aluminium cladding are usually joined mechanically, cutting them precisely and pressing them with fittings. We can offer a better option for joining corners – welding. Aluminium cladding corners connected in this way look like one piece.
