Price of ALU joinery
Determining the price of aluminium 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 aluminium 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 aluminium joinery?
The installation depth, number of chambers, and the thermal properties affect the price, i.e. whether it is a profile with an interrupted thermal bridge or a profile without an interrupted thermal bridge.
The elements of aluminium joinery are available in all the usual dimensions and for extremely large elements we have a wide selection of options for additional interior and exterior fastening available.
The standard glass panes installed in aluminium 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. 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 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 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. Aside from the standard colours of aluminium joinery, we have non-standard colours (from the RAL chart palette), Tiger Drylack colours, as well as wood decorative foil. While standard profiles are available always and at a relatively reasonable price, coloured profiles, i.e. the profiles with various wood decor (golden oak, mahogany, walnut, dark oak…), as well as Tiger Drylack colours and structures are somewhat more expensive and take longer to be delivered.
