Choosing new windows may seem straightforward at first, but in practice, many homeowners make mistakes that can significantly affect comfort, energy consumption, and the overall appearance of their home. By seeking advice from a specialised window manufacturer and carefully considering the key decisions, you can avoid these pitfalls and invest in a durable, long-term solution. Aliplast shares a series of useful tips to help you make the right choice.
Focusing too much on price alone
One of the most common mistakes is looking only at the purchase price. While it is perfectly understandable to keep an eye on the budget, the price alone says very little about the true value of your windows. Cheaper solutions often turn out to be more expensive in the long run due to lower insulation performance, higher maintenance requirements, or a shorter lifespan. To avoid this mistake, it is better to consider the total cost over the product's lifetime. Factors such as energy efficiency, ease of maintenance, and durability play an important role. Aluminium windows, for example, may require a slightly higher initial investment, but they offer exceptional longevity and lasting performance.
Aluminium joinery has an average lifespan of 50 to 60 years. Aluminium profiles are highly resistant to rust, cracking, and warping, and retain their colour exceptionally well. Aliplast even offers a colour range backed by a 25-year paint warranty, which is unique in the industry compared to the standard 10-year warranty. That gives you real peace of mind and long-term quality assurance. Aluminium windows are also extremely low-maintenance, as they never need painting or varnishing. Depending on your living environment and local conditions, cleaning your aluminium windows two to four times a year is usually sufficient. To preserve the colour finish, it is recommended to treat the aluminium once a year with a suitable maintenance product. Aliplast offers a range of mild maintenance products specifically designed for this purpose.
Insufficient attention to insulation values
Windows have a major impact on a home's energy consumption, yet technical values such as Uf, Ug and Uw are still too often overlooked. As a result, some homeowners and renovators choose systems that do not provide optimal thermal insulation. A well-informed decision should be based on the insulation performance of the entire window (Uw value), not just the glazing. Modern aluminium systems combine robust profiles with advanced thermal breaks, enabling them to meet today's stringent energy efficiency standards while delivering excellent performance.
Insulation value explained in brief:
The U-value (thermal transmittance coefficient) indicates how much heat is lost per second and per square metre when there is a temperature difference of 1 Kelvin between the inside and outside. The lower the U-value, the better the window insulates.
For windows, several U-values are distinguished:
- Ug-value: insulation performance of the glazing (g = glass).
- Uf-value: insulation performance of the window profile (f = frame).
- Uw-value: overall insulation performance of the complete window (glass + frame + spacers).
Modern aluminium windows generally offer excellent U-values ranging from 1.5 to 0.8 W/m²K, depending on the type of glazing selected. Aliplast even offers aluminium profile systems that are suitable for passive house applications.
Forgetting to take the home and its architecture into account
Windows play a major role in defining the appearance of a façade. Yet homeowners often choose a solution that does not match the style of their property. This can create visual imbalance and may even affect the value of the home. It is important to consider not only technical performance but also aesthetics. Slim aluminium profiles make large glass surfaces possible and complement both contemporary and traditional architecture. By carefully considering proportions and style from the outset, you can create a harmonious overall look. Choosing windows for your home is an important decision that involves both aesthetic and functional considerations. It is therefore advisable to think carefully about the type of window you need: fixed windows, tilt-and-turn windows, sliding windows, and more. The right choice depends not only on the room in which the window will be installed, but also on the desired appearance and functionality. Do you prefer large windows to maximise natural light, or smaller windows to create a more intimate atmosphere? When you choose Aliplast aluminium windows, you benefit from a wide range of possibilities. They are available in countless colours as well as a variety of designs, making them suitable for every architectural style. If you prefer a traditional look, you can opt for steel-look windows while still enjoying all the advantages of aluminium.
Not comparing quotations correctly enough
Many people request several quotations, but fail to compare them thoroughly. Price differences can often be explained by variations in materials, glazing, finishes, or included accessories. A proper comparison goes beyond the total price alone. Pay close attention to the profiles being used, the glazing specifications, finishing details, and any options included in the quotation. If anything is unclear, ask for clarification so you fully understand what you are getting for your investment.
Conclusion: making a careful choice is a sustainable investment
Choosing new windows is a decision that deserves careful consideration. By looking beyond price alone and paying attention to technical performance, aesthetics, and ease of use, you can avoid the most common mistakes. When this approach is combined with high-quality materials and professional installation, you are investing in windows that will provide comfort, energy efficiency, and visual appeal for many years to come. Aluminium windows stand out as a future-proof solution, offering excellent performance both technically and aesthetically.
