It is usually white and made of pre expanded polystyrene beads.
Expanded polystyrene foam board insulation fire resistant.
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.
To ensure qualitaty and efficient insulation of foundations walls floors or roofs eps materials are the best choice for any type of buildings be it a residential house an industrial a public or an educational institution building.
The purpose of this document is to clarify the performance of expanded polystyrene foam eps when used as insulation material.
There are a few different kinds of foam board insulation diyers should know about.
Exposed foam board insulation fire hazards.
Expanded polystyrene eps is a rigid and tough closed cell foam with a normal density range of 11 to 32 kg m 3.
Coating provides fire protection for expanded polystyrene foam folks are constantly asking if we can apply eoncoat to foam expanded polystyrene foam insulation.
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.

Foamed polystyrene products used in the construction industry serve as an efficient thermal insulation material with multiple uses.
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.
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.
This q a article discusses the requirement for a fire resistant covering for foam and foam board board building insulation.
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.
Foam board insulation is a great alternative to the very common fiberglass batt insulation that is in most of our homes.
Xroof roof insulation boards are ideal for a multitude of roofing requirements inc.
Like practically all organic building materials polystyrene foam is combustible.
Eps is used for food containers molded sheets for building insulation and packing material either as solid blocks formed to accommodate the item being protected or as loose fill peanuts cushioning fragile items.
Expanded polystyrene eps has been extensively tested in terms of fire hazard assessments.
3 fire safety of eps insulation products and insurance 9 3 1 analysis of large fires.
It has a higher r value per inch of thickness it s resistant to moisture and is easy to work with.
However in practice its burning behavior depends on the conditions under which it is used as well as the inherent properties of the material.
