Rubber plays a silent but most important role in fixing glass in aluminum windows and doors. If the rubber is not of good quality, the glass can become loose. Air or water can enter through the window, and there will be complaints of noise. This time, we will tell you how to identify standard quality rubber.
Basic Purpose of Rubber
The purpose of putting rubber between the aluminum section and the glass is to make it airtight and watertight. It protects the glass from shocks and holds it firmly in its place.
Difference between Local Rubber and High Quality PVC Rubber
Two types of rubber are commonly found in the market. It is very important for you to know the difference between them:
Local Rubber
This rubber feels very hard to the touch and has less flexibility. It breaks during installation on the glass due to poor quality. It smells like burnt plastic or strong chemicals. Its color fades after a short time or white lines begin to appear. It dries up and breaks very quickly, causing the glass to rattle when wind hits it from outside.
High Quality PVC Rubber
This rubber is very soft and flexible. If you pull it, it does not break but returns to its shape. Its surface is smooth and shiny. It maintains its condition in both cold and hot weather. It neither melts nor hardens and breaks. It seals the window completely, preventing outside dust and rainwater from coming inside.
Easy Way to Find the Difference Between PVC and Local Rubber
When you buy rubber or have a craftsman install it, perform this small test:
Pull and See: If the rubber breaks after pulling it a little, understand that it is local and made of old material.
Fold and See: Fold the rubber completely at one spot. If a white mark appears or the rubber breaks, it is of poor quality.
Identify by Smell: Good PVC rubber does not have any unpleasant smell.
Best Advice for Windows
Always try to use high quality PVC rubber. Although it might be slightly more expensive than local rubber, it increases the life of your home windows by many years.
