When a house or apartment collapses, its occupants often suffer severe injury or death, but this can also be avoided with effective roofing and insulation.
The roofing material used to protect homes from tree impact is called fire-resistant insulation.
It consists of a thin, flexible layer of material that can be stretched to form a protective layer on top of the foundation of the house or building.
This is used to keep fire-affected structures and structures that are prone to structural damage from falling.
In India, insulation used in roofing can be manufactured from recycled wood pulp or other materials.
In other countries, the materials used are made from plastic or glass and are often made from high-grade petroleum-based products like petrol or diesel.
However, in India, there are few companies producing fire-resisting insulation in bulk, so its use is not as common.
In India, most homes and apartment buildings are constructed on foundations made from concrete.
As a result, there is little information on the use of fire-resistive insulation in these buildings.
Here, we take a look at the most common fire-prone structural materials that are used in building insulation.1.
Concrete and plywoodThe most commonly used materials for building insulation in India are two different types of building materials: cement-coated concrete (CCFC) and ply-coating plywood (PFP).CCFC is a non-combustible, low-density material that is used for roofing in India.
CCFC is commonly used in the construction of homes, while PFP is used in apartment buildings and other structures.
Cement-coaced concrete (CCC) is a type of CCFC that is made from cement and is used as a replacement for the natural fire-retardant properties of the soil.
PFP, on the other hand, is a synthetic form of CCFA.CCFC and PFP are both highly flammable.
When ignited, the fire can cause severe burns to the surface of the building, which can cause the building to collapse.
PFE also contributes to the fire-damage in CCFC-based structures.
In a study carried out by the National Institute of Science Education, India, researchers found that in a sample of over 600 buildings constructed in the period 2006-2008, they found that the CCFC was used for around 92% of the roofing materials used, while the PFP was used only 4.5% of materials.
This means that the use and performance of CCFTC in residential buildings was around 88%.2.
WoodPile board, plywood and polystyrene (PS) are all similar types of materials used for building construction.
In a study conducted by the Indian Institute of Structural Engineers (IISE), they found an average of 8.8 per cent of materials in the residential sector used PFP.3.
PVC-coaled polyethylene (PCE) is the most commonly-used wood-reinforced plastic in India which is used mainly in the manufacture of roofing panels, insulation and for the construction and maintenance of buildings.
PCE is a high-density, flexible, non-fire-retarded material that has a fire-reducing property.
PPE is a wood-coaxed polymer that is a strong fire-repelling material.
In terms of fire resistance, PCE has an excellent fire-proofing capability and it can withstand extreme temperatures as well as extreme rainfall.
It can withstand temperatures of around +50 Celsius (115 Fahrenheit), while PPE has a maximum fire-tolerance of around 2,000°C (3,000 degrees Fahrenheit).4.
PVP, polyvinyl chloride (PVC), polystyrofoam (PVP) and polyethyleneglycol (PEG) are the most widely used fire-rated insulating materials in India that are made up of PVP (polyvinyl acetate), PVP-vinyl acid and PVP(vinyl alcohol) which are used for the manufacture and storage of electrical equipment.
In the study carried by the IISE, they also found that PVP and PPE were used for nearly 80% of residential roofs and buildings in India during 2006-08.PVP is a fire retardant, and is considered a more fire-defending material than PPE.
PVE is a highly flamable material that could cause fire to spread in the case of an accident.PEG is a low-temperature fire-prevention material and is widely used for buildings, while PVC is a water-resistant material that cannot be burnt.
In order to prevent fire, insulating structures should be constructed with high fire-strength in order to withstand the harsh weather conditions.
