What is a fire rated floor?

Fire rated floor doors maintain the fire rating of a 2-hour floor/ceiling assembly where access is required between building floors. Products feature an optional automatic closing system, intumescent fire resistant coating, and a pan cover designed to accept architectural flooring materials.

Do floors need to be fire rated?

Flooring is the last material to be ignited during a building fire and therefore does not require the highest flame resistance.

Is Gyp-Crete lightweight concrete?

Gypsum concrete is lightweight and fire-resistant. A 1.5-inch slab of gypsum concrete weighs 13 pounds per square foot versus 18 pounds per square foot for regular concrete.

What is the R-value of 1 air space?

Cellulose fiber(1 in. thick) 3.70
Flat glass (0.125 in thick) 0.89
Insulating glass(0.25 in space) 1.54
Air space (3.5 in. thick) 1.01

What material has the highest R-value?

Vacuum insulated panels have the highest R-value, approximately R-45 (in U.S. units) per inch; aerogel has the next highest R-value (about R-10 to R-30 per inch), followed by polyurethane (PUR) and phenolic foam insulations with R-7 per inch.

What is a 30 minute fire rating?

30 – 60 minutes can give employees, residents, visitors or other persons enough time to safely escape a fire. These levels of protection are usually used on structural elements of a building to help maintain its integrity during a fire, also giving emergency services more time to control the outbreak of fire.

Is vinyl flooring fireproof?

In fire safety experiments, vinyl flooring has proven itself to be a particularly good material for preventing the spread of fires and reducing hazards. Not only does it typically resist ignition, it also quickly stops burning when the initial fire source is removed.

Is epoxy flooring fire-resistant?

Epoxy fire retardant coating is used to retard the flame spread and allow personnel to evacuate from the buildings during the fire. EFR 300 is a two component solvent free epoxy system which is brush or roll applied and mainly used for concrete and metallic structural buildings (residential and commercial).

Is Gyp-Crete sound proof?

A sound absorbent material, such as rubber matting, gypsum concrete “gypcrete”, or a layer of homasote – will reduce airborne and impact noise transmission into the space below. A note on gypcrete: Typically, wood floors, resilient floors or carpeting are fastened to the gypcrete with an adhesive product.

Can Gyp-Crete be a finished floor?

Gypsum can’t be used as a finished floor, but it can serve as an underlayment for a variety of other floor coverings.

What kind of gypsum to use for fire rating?

However, there are more than 125 different ways to achieve this rating using different combinations of materials including rock, plywood, lightweight concrete, etc. At WestPro Construction Solutions, we use a gypsum cement mixture to achieve this fire rating quickly, efficiently, and cost-effectively.
