Most Energy Efficient uPVC Windows in India

Save upto 30% on your electricity Bills


Windows typically occupy about 15 to 20 percent of the surface area of the walls. Windows not only add aesthetic looks and often a very important aspect of a home, but also a very significant component of home heating and cooling costs. poor windows lose more heat per square foot of area in winter and gain more heat in summer than any other surface in the home.

Today, Prominance have changed the energy performance of windows in a radical way. Prominance energy efficient window systems will make your home more comfortable, dramatically reduce your energy costs and help to create a brighter, cleaner, healthier environment by reducing your carbon footprint.

Prominance Single, Double & Triple glazing uPVC Window systems have the highest thermal efficiency properties, which allows you to have a much larger window surface area and a bigger view of the lush green surroundings.

Double glazing or insulated glazing uses two panes of glass thereby significantly reducing the amount of heat that enters or exits your home. As a result, your house is cooler during summer and warmer during winter.

Because your windows are thicker, they are more effective in reducing the noise that can enter your home. This is especially helpful for those who live near airports, have neighbours with noisy pets.

Windows with double glazing are together to break and are more difficult to be forcefully opened from the outside. This increases the safety level of your house and burglars will be discouraged from breaking in.

When furniture and décor are exposed to too much heat, they tend to wear and damage more easily. With less heat making bits way into your interiors, your furnishings are better protected.

Condensation can be serious problem, particularly in order homes as it causes mould and mildew and in some cases it will also rot timber window frames and damage your family’s health. Double glazing works to reduce excess moisture to your window panes.
