UPVC doors and windows Advantages


Durability and sturdiness

UPVC Doors and Windows are highly durable. Also, they have a better and longer life than conventional Solid Wood Windows or Aluminium Windows.

These Window Systems are resilient too. They are termite and temperature resistant. Also, their lifespan is very long compared to traditional materials.


Sustainable fenestration solution

UPVC is 100% recyclable. So towards the end of its life, it can be converted, reprocessed, and repurposed into other products.

Thus, it is environment-friendly and weather-proof.


Easy maintenance

UPVC Doors are not affected by fungus. So, they are immune to rotting, warping, or rusting.

They are naturally resistant to pollution, chemical, and water. Also, carrying and handling UPVC is easy as it is very light-weighted.


Great insulators

UPVC is a great thermal insulator. It does not allow the outside heat to enter the building and the inside cooling to escape outside.

Also, in adverse climatic conditions, where the temperature is extremely chilling, these Window Systems trap the warmth inside the room; allowing a comfortable living.

Furthermore, UPVC Doors offer sound insulation as well.

If you are living in an area with high noise pollution such as near the airports, highways, etc. Also, UPVC is the right choice for you.  But, UPVC has some disadvantages as well.


UPVC doors and windows disadvantages


Lacks sophistication

Compared to solid wooden doors and windows, UPVC looks less sophisticated and refined. So, the former has a better aesthetic appeal.

Also, UPVC has a limit to customization and personalization as it is manufactured for the masses with more focus on functionality and durability.

Light-weight Structure

Due to their lightweight, these Window systems often get sagged and sashed. So, the frames might rupture over time. Aluminium Windows are much stronger in this respect.

But to overcome this obstacle a Mild steel rod runs through the cross-section of the window to make it stronger and rigid.


How to choose the right UPVC windows?


Proper Window Systems are constituted of many components. Also, many different elements and materials are assembled and engineered together to make good Window Systems.

1. UPVC Profile: The profile or the frame of the window is extremely important as the efficiency and durability of the window primarily depends upon it.

2. Glass Unit: These Window Systems come with double-glazed windows. Also, double glazing comprises two glass sheets that have an air layer between them.

This technology increases the sound insulation capacity of the window.

3. Seals: Seals are responsible for the tight-fitting of the sash to the window frame. Also, they are changed quite often as they are more prone to wear and tear on regular use.

4. Window furniture hardware items: These include the most important components of the Window Systems.

Window handles, locks, interlocks, etc. make up the hardware of  Window.

Also, LGF SYSMAC, Hafele, Hettich, etc are some major brands that offer a wide range of architectural hardware components.

Also, they provide hardware items and window fittings for all types of Window Systems. Thus, superior quality window and door locks are essential for the security of the building.

5. Additional accessories: Mosquito nets, insect screens, blinds, etc. are the add ons that enhance the aesthetics and functionality of the windows.

6. UPCVC window price also plays an important role while choosing: The UPVC Windows price range in India is from Rs 300/ sq ft to Rs 1200/sq ft.

Thus, the material quality, finishes, brands, colours, and many other factors play a role in deciding the UPVC window price.


Challenges with these Windows and their preventive measures


Weather damage

India is a country with extreme weather conditions.


The central and western parts experience extreme heat. But, the northern and eastern parts have low-temperature conditions. The southern part remains hot and humid all throughout the year.

Also, monsoons are terrible in most regions of the country.

Thus, to avoid the damage caused by varied weather conditions, its manufacturers came up with an innovative solution, i.e. to add Titanium dioxide to the Window Systems.


Use of Titanium dioxide in UPVC Window Systems:

UPVC profiles are outdoor products. So, weather damage is a common issue that might compromise the durability and longevity of the entire window system.

Also, Manufacturers add Titanium Dioxide (TO2) to the UPVC compound so as to develop weather resistance in the windows and doors profile.

So, this chemical absorbs the UV light and protects the polymer from degradation, fading, and discolouration.

TO2 also protects the windows from heat and other weather damages; thus, protecting the overall structure and durability of the entire building.


Different wind pressure conditions

Another major problem faced by these Window Systems is the ability to bear the wind pressure at different heights.

This window was originally made for low-rise buildings that do not have to withstand too much wind pressure. But, the material gained overnight popularity and began to be used widely for all types of buildings.

But as discussed earlier, the material tends to sag and sash over time. So, when exposed to high wind pressure, the process gets quicker.


Use of Mild Steel Rods in UPVC Window Systems

To overcome this challenge, the UPVC manufacturing companies came up with yet another creative idea. So, a mild steel rod is inserted in the UPVC cross-section.

Also, this rod makes the entire profile ten folds stronger and powerful enough to withstand extreme wind pressures without getting damaged.

Make your building cooler, safer, and sound-resistant with UPVC Window and Doors. Thus, this window helps in raising your living standards and reducing the lifestyle cost simultaneously.
