There are many elements that influence the price of a window. In this post, we will discuss what we consider to be subjective elements regarding inward-opening windows, in particular the following systems: Eco, Classic, Traditional, HTR, whose price base is very similar.
The best way to check what and how influences the final price of a window is to use our calculator:
Items in the calculator can be easily copied and replaced, observing their impact on the price. Although the calculator is quite extensive, it is intuitive – the selection of individual window components and its options is made easier by the hints that appear on the left side when selecting options. You can make any number of quotes in the calculator and then download the quotes by simply providing your e-mail address.
We show the variables affecting the price of a balcony window/door in groups of factors. Depending on the country of destination, some of the solutions presented below are excluded because they will not meet the requirements set out in local regulations.
THE MOST IMPORTANT ELEMENTS AFFECTING THE PRICE OF A WOODEN WINDOW:
1) wood – profile depth
Profile 68 is a base profile and allows the use of a glazing unit with a maximum thickness of 32 mm
Profile 78 is thicker and more expensive, but allows the use of a glazing unit with a maximum thickness of 42 mm.
Profile 92 is the thickest and most expensive profile of those mentioned, but it allows the use of a glazing unit with a maximum thickness of 55 mm.

2) wood – wood species
The most frequently used type of wood is pine, but for some countries products made of exotic wood (e.g. meranti) or noble wood such as oak or larch are more recommended.
The price depends on the type of wood and is as follows:
– jointed pine (micro) – this is the most economical solution in our production,
– solid pine – this is a more expensive pine wood option than the jointed (micro) one and is most often used for products that are ultimately lacquered,
– meranti – exotic wood (both jointed and solid), which is more expensive than any pine option,
– eucalyptus grandis – exotic wood, which is slightly more expensive than meranti,
– larch – noble wood (both jointed and solid), which is more expensive than meranti and eucalyptus,
– spruce – in the jointed or solid version it is at the price level of larch,
– oak – noble wood (both jointed and solid) is much more expensive than larch and spruce,
– other types of wood available for individual pricing.
The basic characteristics of wood species can be found in the link about wood species.
3) filling – glass
Depending on the expected window parameters (e.g. thermal insulation, acoustic insulation, safety) – the appropriate structure of the glass package is selected.
The standard glazing for window 68mm is a double-glazed package (single-chamber) with a 4-16-4 structure with a Ug=1.1 W/m2K coefficient, which allows to obtain Uw=1.33 W/m2K for the reference window*.
*the reference window is a single-sash window with dimensions of 1230 x 1480mm.
 |
Anything else is more expensive.
The standard glazing for window 78mm is a three-pane (two-chamber) package with a 4-14-4-14-4 structure with a Ug=0.6 W/m2K coefficient, which allows to obtain Uw=0.9 W/m2K for the reference window.
 |
Anything else is more expensive.
The standard glazing for window 92mm is a three-pane (two-chamber) package with a 4-18-4-18-4 structure with a Ug=0.5 W/m2K coefficient, which allows to obtain Uw=0.9 W/m2K for the reference window.
 |
Anything else is more expensive.

4) filling – panels
The standard panel for window 68mm is a flat panel with a 4-16-4 structure with a Ug=1.1 W/m2K coefficient, using 4 mm thick plywood and 16 mm thick thermal insulation foam.
 |
All other panels are more expensive. Examples of panels can be found in the link about door panels.
5) muntins
Our offer includes 4 types of muntins, which are presented below in order from the cheapest to the most expensive:
 |
A – between glass muntins
The most economical option; it is not recommended for wooden windows because it disturbs the aesthetics of the product chosen to emphasize the prestigious character of the property.
B – glue-on muntins WITHOUT duplex
Available in widths of 20/25/30/35/40mm, the wider the more expensive. The price is also influenced by the muntin profile selected from the available ones: softline / slant / retro / ovolo.
C – mullions
Available in widths 56/78/106/130/136mm, the wider the more expensive.
D – Vienna bars (with duplex)
The Vienna bar muntin consists of a glued muntinn + duplex (placed in the inter-pane frame). In a 2-glazed (single-chamber) package, there is room for 1 duplex, while when using a 3-glazed (two-chamber) package, the amount of duplex is doubled due to two inter-pane frames. The greater the amount of duplex, the higher the price.
Duplex adapts to both the width of the mullion and the thickness of the inter-pane frame. Duplex cannot be used in inter-glass frames with a thickness of less than 12 mm.
