One of the most common reasons why investors decide to replace windows is the desire to improve the thermal insulation of the building. Old windows, especially wooden ones or first-generation PVC windows from the 1990s, often let cold air through and don’t protect against heat loss. Through leaky profiles, worn seals, or single-pane window packages, even 25-30% of thermal energy from the building can escape. In practice, this means higher heating bills and reduced living comfort.
Modern aluminium windows, available in Fintecnic’s offer, meet the highest thermal insulation standards. Equipped with advanced insulated glass packages and profiles with thermal breaks, they allow for significant reduction of heat loss. The heat transfer coefficient (Uw) can in such cases be even below 0.9 W/m2K, which means excellent energy efficiency. Such an investment pays for itself quickly, especially with rising energy prices.
Increased acoustic comfort – the silence you need
Contemporary construction increasingly has to deal with the problem of noise. Whether you live near a busy street, railway tracks, or in a densely built urban environment, old windows cannot effectively protect against unwanted sound. As a result, it’s difficult to get peaceful sleep, relaxation, or concentration.
Replacing windows with new, properly configured aluminum models can significantly improve acoustic comfort in interiors. Glass packages with thicker outer glass, laminated glass, or asymmetric assemblies allow noise reduction by even 40-45 dB. This means noticeable sound insulation of the apartment. Fintecnic offers a wide range of solutions for demanding customers, including the use of specialized sound-absorbing glass.
Security – new windows, greater peace of mind for residents
Old windows, besides low thermal and acoustic insulation, are also much less resistant to burglary attempts. Thin profiles, outdated locks, or lack of modern hardware make them an easy target for potential intruders. Meanwhile, modern aluminum windows offer a range of security features that effectively deter thieves.
Fintecnic products are equipped with anti-pry hardware, mushroom bolts, steel catches, and handles with locks or keys. For the most demanding customers, solutions in RC2 or RC3 class are available, recommended by police and insurers. Thanks to this, you can sleep peacefully, knowing that your home is properly secured.
Aesthetics and modern appearance – better look of house and apartment
The visual aspect is also significant. Old windows often spoil the facade or apartment interiors. Discolored, damaged frames, yellowing seals, and unaesthetic hardware ruin the overall appearance of the property. On the other hand, new aluminum windows from Łódź offer not only functionality but also modern design.
Fintecnic offers profiles in fashionable colors such as anthracite, matte black, or classic white. There’s also the possibility of personalizing the shape and finish of profiles, which allows matching windows to the building’s style – both modern and classic. Window replacement immediately refreshes the home’s appearance, which is important not only for residents’ comfort but also for potential buyers in the future.
Property value increase and tax benefits
New windows are also an investment in the future. Properties that have been modernized and equipped with energy-efficient windows are more attractive to potential buyers and can achieve higher selling prices. This is particularly important for apartments in cities and single-family homes.
An additional argument in favor of window replacement is various types of funding and tax benefits, such as the “Clean Air” program, thermal modernization tax relief, or local ecological subsidies. Fintecnic supports its customers during documentation preparation and helps select appropriate solutions from formal and technical perspectives.
