How uPVC Windows Keep Your Home Cool During the Summer Heat Jun 23, 2025 By Fenesta

Indian summers are known for rising temperatures and scorching days, which is something that also impacts the indoor temperature, leading to increased heat and humidity inside. In such a situation, effective cooling is more than a luxury but the need of the hour. Summers can easily lead to increased use of air conditioners and consequently result in huge utility bills. To combat this, it is important to consider effective but sustainable ways to help control indoor temperatures, which also includes choosing the best windows to reduce heat in summer, like uPVC windows. You can choose from different types of uPVC windows for their heat-resistant properties and ensure your home remains cool even in the summers.

Why Choose uPVC Windows?

The many benefits of uPVC windows in the hot weather make them a good choice for homes. Keeping your home cool during intense summers using air conditioning is not enough. It also requires the right windows. uPVC windows are the best windows to reduce heat in summer days as they come with enhanced insulation properties and are easy to maintain. You can choose from different types of uPVC windows for their heat-resistant and insulation properties, which allow for easy indoor temperature maintenance, helping you save energy and lower your utility bills. Here are the features of uPVC windows that make them a good choice for summers:

Multi-Chambered Profile

uPVC windows are designed with multi-chambered profiles that offer improved insulation, noise reduction, and thermal efficiency. These windows are designed with air pockets created within the window profile, which act as a barrier and effectively insulate the window frame. Multi-chambered window profiles reduce drafts and prevent heat transfer from the outside to the inside and vice versa. This helps maintain a consistent indoor temperature, reducing energy consumption and improving the overall energy efficiency of your home.

Low Thermal Conductivity

One of the biggest benefits of uPVC windows in the hot weather is that uPVC has low thermal conductivity, which means that the material is a poor conductor of heat. That is how uPVC window frames do not readily transfer heat, helping reduce heat gain during the summers and stabilising the indoor temperature. Thereby, uPVC windows contribute to creating a comfortable living environment.

Airtight Sealing

uPVC windows are designed with fusion-welded joints and airtight sealing, which reduces air leakage and improves the thermal performance of windows. Multiple point locking systems provide additional security and help keep out dust, rain, pollution, etc. The windows are also installed using silicon sealant to ensure that there are no gaps, preventing drafts and air leakage. This also contributes to helping the windows maintain the indoor temperature.

Temperature Resistance

Another one of the top benefits of uPVC windows in the hot weather is that unlike traditional materials, uPVC does not warp, crack, contract, expand, fade, flake, or peel. uPVC windows maintain their structural integrity while also protecting the indoors from degradation by UV or excessive light exposure.

Double-Glazed Glass

You can choose to install uPVC windows with double- or triple-glazed glass for improved thermal insulation. Double-glazed glass comprises of two glass panes within the same window frame, with the space between them being filled with insulating gas or air. Triple-glazed glass is designed in a similar way, with three glass panes instead of two. The trapped air in these types of glass acts as an insulator, preventing heat transfer as well as minimising condensation.

Frequently Asked Questions

Are uPVC windows energy-efficient?

Yes, uPVC windows have high thermal insulation properties. uPVC has low thermal conductivity, which helps prevent heat gain. The windows are designed with air-tight sealing, fusion-welded joints, multi-point and locking systems, and installed using silicon sealant to seal any gaps, which further helps improve their energy efficiency.

How should I maintain my uPVC windows?

uPVC windows are low maintenance windows. All you need to do is clean them on a regular basis to keep them looking as good as new. You can use a soft cloth and mild soap solution to wipe the windows and their mechanisms down. You should also get the components of the windows, like the hinges, locks, etc., checked and lubricated periodically.
