Modern plastic windows are usually more energy efficient and durable than the old wooden ones that were so popular in the past. However, not all plastic windows are the same. And to choose really good ones, it is recommended to pay attention to a number of factors.
1. Quality of PVC material
The quality of the PVC material from which the plastic window panels are made plays a very important role: it is on it that the durability of the windows and their resistance to yellowing or cracking over time depends. Therefore, it is advisable to pay attention to the reputation of the panel manufacturer and what raw materials they use.
2. Profile and chamber design
The number of chambers also plays an important role: the more chambers inside the profile, the better the sound and heat insulation. A system of 5-7 chambers is usually ideal for cold climates.
Profile thickness is also important: thicker profiles provide better insulation and structural integrity. Look for profiles that are 70 mm thick or more for good insulation.
3. Double glazing
Double or triple glazing: Triple glazed windows provide better thermal and acoustic insulation than double glazing. It is advisable to take into account the climate of your region to decide which option is best for you.
A Low-E coating on the glass reflects heat back into your home, increasing the energy efficiency of the windows. Filling the panes with argon or krypton gas can improve thermal insulation. Both features are definitely worth considering.
4. Energy efficiency
A lower U-value of windows indicates their better insulation properties. Choose windows with a U-value of 1.1 W/m²K or lower.
As for energy efficiency ratings, check if the windows have a label with this rating (for example, the A++ to E scale used in Europe). Higher ratings indicate better energy efficiency.
5. Security features
Make sure that the frames of your future windows have steel reinforcement for extra strength. In addition, windows with multi-point locks offer better security than windows with a single lock, and this is also worth paying attention to.
If window security is important to you, you should also consider laminated or tempered glass: these types of glass are harder to break.
6. Ventilation options
Weep holes in uPVC windows provide continuous background ventilation, which is important for preventing condensation and maintaining indoor air quality.
In addition, tilt and turn windows can be opened in two ways, allowing you to better control the ventilation in the room.
7. Installation quality
The quality of the windows themselves is, of course, very important, but equally important is who and how they are installed: professional, correct installation is crucial to ensure that the windows work well. Therefore, it is advisable to choose a certified and experienced installer.
Warranty and after-sales service is another important factor to pay attention to: make sure that the windows come with a warranty and that the installer offers good after-sales support in case of any problems.
8. Value for money
While the cost of windows is certainly important, it is not advisable to compromise on quality. Invest in windows that offer good energy savings, durability, and low maintenance over time, as this will help you save on your heating and cooling bills in the long run.
