  1. Your uPVC window and the wall connection should be as durable as the roof cover-

If you look in the most basic way, a window is exposed to the very same external factors and conditions that the walls or roof of a house are subject to. That’s why it is imperative that the window is properly connected with the walls of the building and that the insulation of those connections should be “as leak-tight as the roof”. Apart from that, windows make up the majority of the space within the wall openings.

The key points of the “installation philosophy and history” deal with the movement joints located around the window.

There have some small gaps where the materials mechanically bind the window to the wall and importantly, the thermal insulation material as well. Just like the entire roof surface, they must also be protected against uncontrolled penetration by rainwater.



the connections and the structures between the uPVC windows and the walls of a house must be more airtight, watertight, and vapor-tight on the inside than on the outside, thus allowing moisture to evaporate to the outside to keep the building fabric dry. The protections should in particular avert the rainwater into the structure of the connection and must, in a controlled manner, drain the water and moisture that has managed to penetrate the thermal insulation layer. It can be achieved by covering the thermal insulation of the connections with vapor barrier materials. This can be possible if you use materials that allow evaporation.



  1. The windows and the walls of a house should form a uniform and durable assembly-

this is another important rule you have to remember while installing the uPVC window in your room. you should know that the Mechanical Forces are caused by wind pressure and suction, the stresses come from temperature fluctuations, and other mechanical stresses determine the durability of the connection between the window and the wall. If you do not have a clear knowledge of the window installation and window-wall connections are made incorrectly, then the process of damage to the window and the house starts immediately after the installation works are completed. In India, these problems are common here. Temperature varies from state to state. If the connection between the wall and the window is not durable and flexible, then the leaks occur, and the damage starts. Gradually the gaps forms from the outside and rain water come, moisture, and external air come through the gaps. You have to keep in mind that these damages can be permanent and permanent damages are irreversible. Therefore this principle is a key point to keep in mind during the uPVC Window and Door Installation in Kolkata.

Using a boundary is important as it separates the outdoors from the interior of the building must be established along the entire surface of the external wall and must not be broken. The Breaks in the sealing connections are the most common cause of the negative phenomena referred to as thermal bridges, which lead to uncontrolled energy losses and condensation. 


  1. Removal step-

While installing a new uPVC window in your room, you need to remove your existing window. The step starts by covering the surrounding with durable dustsheets. Experts use a screwdriver then they remove all the opening sashes. After that, starting from the top corner, they have to start cracking and remove the extra glass. As a well trained expert professional, they will remove all the glasses from inside of the room to ensure proper disposal. In the end, he will cut through the plaster seal with a crosscut saw to get rid of excess remaining frame members.




We have discussed the top three “Golden Principles” which cover a large percentage of the most common yet avoidable errors in uPVC window and door installation in kolkata. You just need to keep them in mind during the installation process, then you get to find yourself surprised at how many errors you can avoid.

The thing you should never forget is that the glazing gap below the glass should be proper. Overall, there should not be any hairline cracks; plus, the handle height needs to be ergonomically correct. Hardware Despite the perfect frame and glass, any glitches in the hardware are enough to spoil the look of your uPVC doors and windows.

The maximum fault lies with the installation and not the product. After all, the wheel would not have been half as useful if it had been placed on the top of the vehicle instead of at the bottom.
