You have just bought a house which needs to undertake renovation work such as all the paint and wallpaper, part of the floors and especially all the frames which are far too old and let the air through like a colander ! On the other hand, by inquiring, quickly, it should be noted that the price will also depend on the type of glazing chosen.
An important point that will determine the cost of your new windows is their size, i.e. whether it is a standard format or not. In the first case, the price will be attractive since the windows are mass-produced, but in the second case, you will have to have a window made to measure, which will increase the bill.
In addition, it will be necessary to add to the price of the window, that of the installation because it is better to call on a professional for this kind of thing:if your window is badly installed, it will not be waterproof and you can only blame yourself. 'to you. While a professional not only has the experience, but if you ever had a problem with the installation, they would be responsible for it and fix it.
Obviously, in the first place you will have chosen the material chosen for your windows because of course, it has consequences on the price of the windows:wood, aluminum or PVC, from the most expensive to the least expensive.
Finally, the price will greatly depend on the type of glazing chosen:single, double or triple glazing, laminated glass, etc.
First of all, single glazing is really to be avoided because it does not at all satisfy the energy saving concerns that everyone is looking for today to lower their energy bill. Beware because if you actually pay less for it, you will regret it later paying your heating bills.
Double glazing is now almost universal, as it provides good insulation. The principle is to have two panes between which is stored air or krypton. There is then a whole range of prices depending on the thickness of each pane, on the one hand, and the volume of air or gas trapped. The quality of the thermal and sound insulation will depend on this and the price will vary from approximately 150 to 230 €/m² or even more.
Triple glazing will be even more efficient than double glazing, but given its high cost which can double the price of double glazing, it is often reserved for low-consumption houses or passive houses, who have, at the same time, designed their project with very strong insulation techniques without thermal bridges, with great airtightness, a specific ventilation system, etc.
To conclude, it is very difficult to give prices for a PVC window because different parameters intervene not without consequence on your final invoice. It is therefore necessary to define what you want in terms of quality of glazing and material, at first. Afterwards, the professionals will make you specific offers.
