Features And Benefits

Energy Efficient

Every home in India is troubled by dust which increases the efforts in cleaning. The wind brings in dust from roads, construction sites, pollen, vehicle traffic, and occasional dust storms. Dust impacts your health adversely giving rise to chronic illnesses like asthma, allergies, and skin problems. Dust enters through cracks and gaps in the old windows and doors. Switch to Vonzo uPVC windows and doors and the problem is hugely reduced.


Typically most UPVC windows, doors, and external facias will come in white. However, developments in the manufacturing process have meant homeowners are now allowed to more than just color but a series of customizable shapes, styles, and imitation effects such as wood grain.

Installation companies and manufacturers can now tailor UPVC products to your desired specifications; meaning windows and doors will outfit perfectly into your home or property.


The security of a property or home is paramount to any window or door installation. This is why UPVC exceeds expectations with an ultra-light yet sturdy frame, used in conjunction with various locking combinations and a double-glazed pane of glass will prevent an intruder from breaking in.


Energy efficiency is at the front of everyone's mind when it comes to new windows and doors and the choice of materials used will impact the warmth and window energy rating of your home.

UPVC is a low conductor of heat meaning when fitted correctly it will form a closed-air system minimizing the heat loss, experienced by non-insulating materials.

Low Maintenance

UPVC is a low-maintenance material, unlike natural materials that require annual sanding, varnishing, and repainting. Windows & doors made from UPVC can last for decades without any sign of weathering, the only upkeep is a wipe-down clean with soapy water to prevent staining and remove grime or dirt.


The material is incredibly tough meaning the frames can cope against the most extreme elements and are not affected by rot and corrosion which is especially advantageous for properties located near the seaside where high salt content can be problematic. The UPVC coating is also protected against ultraviolet (UV) rays which prevent the material from fading in prolonged sun exposure.


UPVC windows can come in various window style configurations providing an efficient ventilation system with effective airflow into a room. An effective window configuration is called 'tilt and turn' which consists of a two-window arrangement that can open in two separate directions providing draft-free ventilation. When in the tilted position inwards, hot air can escape through the top and side openings while turning the window to open fully can quickly ventilate the atmosphere of an entire room useful for cleaning or refreshing.


The average life span of UPVC windows can range between 40-80 years and are made from mostly recyclable materials to sustain minimal long-term impact on the environment.

When replacing old windows and doors made from UPVC ask your installer if they will be disposed of accordingly to ensure are recycled, and the materials can be reused in other products such as pipes, plumbing fittings, and more.

Weather Resistant

Weathering is a common problem amongst most materials used on the exterior of a property. UPVC windows and doors do not react with water and air and are not susceptible to the natural elements, meaning a longer life span without aging.

While UPVC can stand up to the weather and requires less maintenance than naturally occurring counterpart materials such as wood, we recommend taking regular care of any external UPVC installations including soffits and facets to ensure their longevity.


The UPVC material works in combination with the double-glazed window panels to help decrease the amount of noise that can pass into your home. Most UPVC windows and doors should reduce external noise by up to 50% compared to traditional counterparts.

uPVC windows are crafted from sections of uPVC profile, which are cut and joined together to fit in a window. These profiles are produced by forcing molten PVC through a precision die, the material is cooled almost immediately before being cut to length. It was in the 1960's when the production of uPVC windows began in Germany. This was then followed by Britain and America when manufacturers became aware of its benefits and advantages over wood and aluminium. Today, uPVC windows are the most cost-effective fenestration that can fit into a home. The lowest installation cost when compared with other materials, high energy savings over the life of the windows, and low maintenance costs make these windows a thoroughly compelling choice. Therefore, due to its innumerable advantages over wood and aluminum window frames, it has gained worldwide popularity. In countries like UK, the USA, where it is also known as vinyl or vinyl siding, uPVC has garnered more than 60% market share. In fact, 8 out of 10 people who are either replacing their windows or renovating their houses have opted for high-quality uPVC window brands. With most architects and contractors shifting towards uPVC solutions, today it is considered to be the future of Indian fenestration.
