Prices of PVC joinery

blog cijene pvc

Determining the price of PVC joinery is not simple and it depends on many factors, and it is also one of the most important things when selecting the windows and doors for your home. In this section we would like to describe which elements affect the price of pvc windows and doors, and in what way. In order to get a price for your order that is as accurate as possible, we would like to ask you to use one of the order forms or contact us directly.

 

What are the factors that affect the price of PVC joinery?

 

Profiles

 

Profiles used to make windows are made from PVC (polyvinyl chloride). Various additives are added to the PVC that determine the shade of whiteness, smoothness, increase the strength, elasticity, UV resistance, and similar. The quality and origin of the granules themselves definitely affect the durability of PVC windows, but also the price of the profile.

 

Aside from that, the price is also affected by the installation depth (70mm, 82mm, 90mm…), the number of chambers, and the thickness of the walls, because all of that determines the quantity of the material required for the extrusion of the profiles. Considering the thickness of the walls, according to the European standard EN 12608:2004, the profiles are sorted into three classes: A, B, and C. A class profiles must have visible walls (marked in red) ≥ 2.8 mm and invisible (marked in blue) ≥ 2.5 mm. The profiles made by VEKA that we use in production are exclusively A class, with the thickness of external walls of 3.0 mm.

 

Profile dimensions

 

The PVC joinery elements are available in all the usual dimensions, because they are provided with additional strength by the steel reinforcements in PVC profiles. Iveta profiles always have a closed steel tube in their frames, which guarantees high strength and stability. For exceptionally large elements, we have a wide selection of options for additional interior and exterior reinforcement.

 

Shape of windows and doors

 

In order to prevent the boring and uniform look of faces of buildings, architects often decide on elements with irregular shapes, i.e. for pitched and arched windows and doors. While the pitched elements deviate from the standard rectangular ones only by the angle, which is different from 90°, and require no additional equipment, with arched shapes it is necessary to achieve the conditions under which the profiles can be bent. In order to achieve those conditions, the profiles are heated in a glycerine oil bath for about 20 minutes at 125°C so they could be bent to the desired radius on a special bench and in profiled moulds. Iveta d.o.o. owns the necessary equipment and can bend the profiles for their own needs, but also as a service if there is an order.

 

Glass panes

 

The standard glass panes installed in PVC windows are 24 mm IZO glass, with the composition 4-16-4. Lately, with the increased awareness and the necessity of saving energy, triple-layer 36 mm thick glass panes with the composition 4-12-4-12-4 in profiles with the installation depth of 70 mm are becoming more and more common, as well as 44 mm glass panes with the composition 4-16-4-16-4 in Alphaline 90 mm profiles. Aside from increasing the thickness of IZO glass and the number of layers of glass, we can improve thermal insulation by using glass panes with low emissivity coatings (low-e), as well as vanadium dioxide and the neutral gas argon in the space between the glass panes.

Aside from that, the application of multilayer glass is another option (lamistal – triplex), where two glass panes are glued together as one with a transparent PVB (polyvinyl butyral) film between them. Those types of glass panes increase safety because they do not shatter when broken; instead they remain in one piece on the film. Also, this glass increases acoustic insulation by 2-3 dB.

Aside from thermal and acoustic insulation, the glass panes also offer protection from Uv radiation. If we want to increase that level of protection, we have many kinds of tinted and refracting glass panes available.

 

Fittings

 

Fittings enable the joinery to open and close, and according to their method of operation we have: casement, tilt, turn and tilt, slide, turn and slide, lift and slide, fold, etc. Fittings have a crucial effect on the reliable long-term function of windows, but also on the level of safety, or burglary protection. In that respect, we have normal fittings, fittings with basic security elements, and anti-burglary fittings class 1 (WK 1), class 2 (WK 2), and class 3 (WK 3).

(Recently a new classification is used, from RC1 N to RC 3)

 

The safety is also affected by the number and shape of the locking elements on the fittings, and the level of safety is determined depending on the time and the tools required for breaking in. Aside from that, the quality of fittings is also determined by their resistance to corrosion, which is especially important near the coast, near industrial facilities, farms, and similar.

 

The colour of the profile

 

The colour of the profile also affects the price of windows, as well as the delivery time. While standard white profiles are available always and at a relatively low price, for coloured profiles, i.e. profiles with various wood decors (golden oak, mahogany, walnut, dark oak…) you should consider that the price will be somewhat higher. Nevertheless, those profiles are also available with a short delivery time. For non-standard films (light oak, pseudotsuga, numerous shades of grey, green, blue, and other colours) there is a somewhat longer delivery time.
