Wooden windows

Aesthetics of natural wood, energy efficiency and durability are the key advantages of wooden windows. WITRAZ SIA offers wooden windows made of carefully selected timber (pine, meranti, oak, larch) that meet strict European quality standards. Laminated profile in 3-4 layers provides stable geometry, high stiffness and long service life.

IV 78 Euroline – universal choice.
Wood species: pine, meranti, oak, larch.
Profile: laminated wood 3-4 layers, thickness 78 mm.
Fitting: MACO MULTI-MATIC.
Uw: 1,1 W/m²K.
Glazing: 24-40 mm.
Ug: 1,1 W/m²K; possible option Ug = 0,7 W/m²K.
Best for: apartments and houses, where reliable thermal and noise insulation are needed at an optimal budget. Suitable for most climat conditions.

IV 88 Euroline – increased energy efficiency.
Wood species: pine, meranti, oak, larch.
Profile: laminated wood 3-4 layers, thickness 88 mm.
Fitting: MACO MULTI-MATIC.
Uw: 1,0 W/m²K.
Glazing: 44-50 mm.
Ug: 0,6 W/m²K; possible option Ug = 0,5 W/m²K.
Best for: energy-efficient projects with increased thermal and acoustic requirements, private houses with modern engineering.

IV 92 Euroline – maximum warmth and silence.
Wood species: pine, meranti, oak, larch.
Profile: laminated wood 4 layers, thickness 92 mm. Wide profile for better heat and sound insulation.
Fitting: MACO MULTI-MATIC.
Uw: 0,91 W/m²K.
Glazing: 48-54 mm.
Ug: 0,5 W/m²K; possible option Ug = 0,4 W/m²K.
Best for: northern regions, objects in noisy areas.

How to choose: as a rule, wider profile allows thicker glass and can provide better heat and sound insulation. If the maximum efficiency is important – look at the IV 92 Euroline system; if you need a reasonable balance – IV 88 Euroline; for typical tasks – IV 78 Euroline.

Unitas Window – 180° rotation and easy care.
Wood species: pine, meranti, oak, larch.
Profile: laminated wood 3 layers, thickness 68 mm or 78 mm.
Glazing: 24-44 mm.
Fitting: G-U.
Pivot windows are ideal for quick and frequent ventilation. Thanks to the special construction and individual hardware system, the window can be tilted 180°. The adjustable stopper fixes the sash in any position, which makes it easier to ventilate and clean the windows.

Casement System – classic outward opening.
Wood species: pine, meranti, oak, larch.
Profile: 68 mm.
Glazing: 24-30 mm.
Ug: 1,1 W/m²K.
Outward-opening casement windows help you plan interior space more efficiently. EASY CLEAN hinges are included in the standard package.

System Sash – traditional English-style sliding windows.
Wood species: pine, meranti, oak, larch.
Profile: 158 mm.
Sash width: 56 mm.
Glazing: 24 mm.
Ug: 1,1 W/m²K.
Mechanics: traditional cast iron weights or springs.
The window works on the principle of raising and lowering the sash. Special weights or springs support the movement.

Scandinavian System – for windy regions.
Wood species: pine, meranti, oak, larch.
Profile: laminated wood 4 layers, thickness 95 mm or 117 mm.
Fitting: IPA.
Glazing: 24-40 mm.
Ug: 1,1 W/m²K; possible option Ug = 0,7 W/m²K.
In strong winds, the sash is pressed tighter against the frame, making the window even more airtight. Outward opening does not “eat up” interior space, which makes furnishing easier. Optional external aluminum cladding available.
