Expanded Polystyrene Foam Board Insulation Fire Resistant

However in practice its burning behavior depends on the conditions under which it is used as well as the inherent properties of the material.

Expanded polystyrene foam board insulation fire resistant.

Coating provides fire protection for expanded polystyrene foam folks are constantly asking if we can apply eoncoat to foam expanded polystyrene foam insulation. Since most fire codes call for a minimum of half hour fire rating over foam insulations paneling would probably not provide a sufficient fire barrier over the foam insulating board. Foam board insulation is a great alternative to the very common fiberglass batt insulation that is in most of our homes. The thermal conductivity of expanded polystyrene foam of density 20 kg m 3 is 0 035 0 037 w m k at 10 c.

Expanded polystyrene eps has been extensively tested in terms of fire hazard assessments. Of fire resistant constructions used to compartmentalise buildings. 50mm cellecta hexatherm xroof 300l is an extruded polystyrene thermal insulation board designed specically for inverted roof applications where a high resistance to compression and water absorption is essential. Like practically all organic building materials polystyrene foam is combustible.

While eoncoat will not bond chemically to polymers like it does to cement steel and wood it will bond mechanically the way other coatings do to surfaces that are rough. Astm c578 standard specification for rigid cellular polystyrene thermal insulation addresses the physical properties and performance characteristics of eps foam as it relates to thermal insulation in construction applications. 3 fire safety of eps insulation products and insurance 9 3 1 analysis of large fires. Expanded polystyrene eps is a rigid and tough closed cell foam with a normal density range of 11 to 32 kg m 3.

This q a article discusses the requirement for a fire resistant covering for foam and foam board board building insulation. It is usually white and made of pre expanded polystyrene beads. When installed correctly expanded polystyrene products do not present an undue fire hazard. Xroof roof insulation boards are ideal for a multitude of roofing requirements inc.

There are a few different kinds of foam board insulation diyers should know about. Exposed foam board insulation fire hazards. Foamed polystyrene products used in the construction industry serve as an efficient thermal insulation material with multiple uses. What is foam board insulation.

The purpose of this document is to clarify the performance of expanded polystyrene foam eps when used as insulation material. The behaviour and performance of a building insulation material in relation to potential fire hazards depend firstly on the chemical and nature of the material but also on its condition at installation and its specific application.
