Fire Resistant Siding Options

The secret to fiber cement s durability is also what makes it fire resistant.

Fire resistant siding options.

For example vinyl siding may develop a hot spot begin to melt and eventually combust causing a house fire to occur. More importantly steel is fairly neutral in the sense that it isn t going to exacerbate a fire or cause a hot spot to turn into a fire. Choosing fire resistant siding should be a primary factor when choosing aesthetically pleasing siding. Options like cement board siding come in a variety of modern textures profiles sheens and shapes providing an abundance of design flexibility while still being.

However viewing the side of the building as a system use of noncombustible or ignition resistant materials will reduce the potential fire exposure on windows and the eave area of a building. Unlike wood siding fiber cement siding doesn t burn even under extreme heat. Even in a weakened state steel won t melt. 90 of the planks are made of materials that won t burn giving fiber cement siding a class 1 a fire flame spread rating the highest classification available.

Expect to pay between 6 50 and 8 50 per square foot installed. Steel is naturally resistant to fire. Flammable materials like wood are often made resistant to a fire by the use of flame retardants.

Gypsum board also known as drywall consists of a layer of gypsum sandwiched between two sheets of paper. And the good news is these two criteria don t need to be mutually exclusive. That means homeowners have up to an hour before the material will give into the heat of a fire and begin spreading flames into the interior walls. When properly installed against fire resistant materials plaster siding also known as stucco regularly achieves a one hour fire rating.

Manufactured using a highly effective fire retardant and underlaid with a fire resistant barrier this assembly is one of only a few synthetic roofing materials to get ul s class a fire rating. Many structural materials will require underlying gypsum sheathing in order to achieve a good fire resistant rating and gypsum board is the most commonly used fire resistant interior finish. Steel siding not only offers protection against a fire it is also naturally resistant and does not require the use of fire resistant treatments. Chemical flame retardant sprays help improve the fire resistance of this house siding material.
