What is considered fire rated plywood?

What Is Fire-Rated Plywood? Fire-rated plywood is a type of plywood that has been specially treated with chemicals that create a physical barrier to the spread of flames. This treated wood will char but not oxidize, dramatically reducing the progress and spread of fire in buildings.

What type of plywood is fire resistant?

A lightweight, total wood product with advanced fire retardancy. It is ready to use in building projects upon delivery, no other fire treating is required.

What is class C plywood?

C-grade is unsanded and may have several minor defects that will need to be repaired with knots up to 1 1/2 inches across, discoloration and sanding defects. C-grade plywood should be used when appearance is not important, such as for subfloors or garages.

Can you get fireproof plywood?

You can also get fire rated plywood that is perfect for exterior applications and places where the humidity can reach 95% or higher. For example, you could get FRT plywood that prevents water from leaching the ply grain’s fire-retardant substance, depending on the type.

Is marine plywood fireproof?

During manufacturing each individual layer of core veneer is treated for fire resistance prior to the final assembly of the plywood panel, which provides flame- retardant properties throughout the board. The flame retardant properties of Fireshield Marine are not compromised when the panel is machined or sanded.

What is AC plywood?

AC plywood is made from thin sheets of wood pressed tightly together to create a durable and strong piece of plywood. One side of it is sanded and finished which makes it graded “A”. The other side of the board is not sanded or finished, so it is graded “C”.

Can you get fire retardant plywood?

Fire retardant plywood is specially treated with chemicals that act as a physical barrier to fire. The sheet material works by utilizing two mechanisms. One of them is reducing the flammability of fire-resistant plywood by lowering the rate at which flames travel and subsequently slowing down combustion.

Is plywood a Class C finish?

Untreated or unpainted (intumescent paint) plywood is considered a Class C finish.

How do you make plywood fire resistant?

Fire-retardant plywood is made by adding a retardant to kiln-dried, untreated plywood using a high-pressure system that completely infuses the wood with the chemicals. The untreated wood is placed in a sealed retort chamber, where the air is removed to create a vacuum.

Is MDF fire rated?
