What Is Fire Retardant Plywood? | Uses | LCETED

Fireproof plywood is a type of plywood that is treated with special fire-retardant chemicals on the manufacturing process, thus making it excellent in fire resistance. This is also known as FR grade plywood.

 

USP OF FR Grade Plywood.

1.   Bend Resistant

2.   Intense Screw Holding

3.   Barrier Against Fire

4.   Extra Strong

5.   Fire Retardant

6.   Eliminates Toxic Smoke

7.   Delay Temperature Rise

8.   Fire Retardant Chemicals

 

It is commonly used in public places, where the risk of fire has to be reduced such as for making the woodwork in the kitchens of large restaurants, or for the interior woodwork done in public theatres and halls, and the wood used in the railway compartments of our trains. It can also be used in homes and offices, for car interiors, and any other such places where the risk and spread of the fire have to be reduced.

 

The Indian quality standards for the manufacture of FR grade fire-resistant plywood are specified in document IS:5509. The rate of burning of the plywood should be more than 20 minutes, the time taken for flames to penetrate the plywood has to be more than 30 minutes.

 

Chemicals such as diammonium hydrogen phosphate, are used to make fire retardant plywood. The addition of fireproofing chemicals gives the plywood better-fireproofing qualities such as,

 

1. Lesser tendency of spark and ignite.

2. Slow burning, having a decreased tendency of the fire to spread over the surface of the plywood.

3. Low flammability and lesser smoke generation.

4. Higher flame penetration time.

 

The usage of FR grade plywood for making home furniture is quite limited, however for the discerning customers, for whom cost is not a major concern, and who want to reduce the chances of fires in their homes, FR grade plywood can be a good choice. Other than the additional fire-retardant properties of FR grade plywood, all other characteristics of FR grade plywood are more or less similar to the regular plywood used that is used for making home furniture.

 

The sizes and thicknesses of fire retardant plywood are the same as those for the commercial MR grade and the Exterior BWR grade types of plywood.

Fire Retardant Plywood Thickness - 4, 6, 9, 12, 16, 19Mm,

Standard Size Sheets – 8’×3’, 7’×4’, 7’×3’, 6’×4’, 6’×3’ (Commonly Used).
