PVC windows – against fire

With the creation of the world’s first dwelling, it became clear that a window was indispensable. However, everything that is an integral part of the house should be not only beautiful and practical, but also safe. The worst disaster for residents is a fire. Firefighters are confident that its development depends on the windows and, in particular, on the material from which they are made. Wooden frames are highly flammable. If glass breaks, an increase in air flow maintains and intensifies the fire. This is typical for wooden windows. And what about plastic?

With the advent of new generation window structures made of polyvinyl chloride (PVC), the window is no longer a source of danger in the event of a fire. The zero flame spread index specified in the technical characteristics of PVC windows is an indicator that indicates the incombustibility of the material. The softening point of PVC is from 175 ° C to 186 ° C. PVC contains 75% combined chlorine, which prevents the spread of fire. Compared to wood, PVC generates significantly less heat when it burns. We can say with confidence that window structures made of such a modern material as polyvinyl chloride do not support combustion in the absence of a fire source.

When PVC burns, no lethal substances are emitted. Hydrogen chloride has a pungent odor and is easily detected. In addition, it reacts with water vapor and forms hydrochloric acid. The concentration is so low that it is safe for human health. Carbon monoxide, the so-called odorless carbon monoxide, is also released when wood burns, so there is no need to talk about the danger of substances released from PVC during combustion. This material is safer than wood.

Vacuum insulating glass units are good heat insulators. If a fire breaks out in an apartment or office, a double or triple glass unit will “strangle” it. A double-glazed unit is a construction of two or more glasses. If the first glass bursts from a strong temperature drop, the second will not allow the fire to spread – its temperature will approach the critical much more slowly.

For offices filled with computer technology, the problem of fire is the main one. In order to prevent a fire, fire extinguishers and automatic fire alarms are used. Including double-glazed windows with a high class of fire resistance. There are special fire protection standards for PVC window structures.
Fires do not occur where they are not provoked.

It must be remembered that plastic window sills are not intended for installing hot objects on them – irons, electric tongs and others, and computers must be turned off before leaving. There is no need to create risky situations, and fire safety will always be at its best.
