INSULATION - Greenworld Structures

INSULATION

EPS

Expanded polystyrene EPS is a closed cell, lightweight foam which by itself, depending upon density, and has a compressive strength between 10 and 60 pounds per sq. inch. EPS is ideal foam for most construction applications. EPS is an inert insulation plastic material product with no future chemical activity. It has no nutritive value for plants, insects or other pests to feed upon. It will not rot and is extremely resistant to mildew.
Custom floor design solutions are available upon request for specific applications.

EPS is manufactured in conformance with the following standard:

  • ASTM C 578 (Thermal Insulation)

  • ASTM D 6817 (EPS)

  • ASTM E 2430 (EIFS boards)

Environmental Advantages

  • Inert, non-nutritive, highly stable

  • Contains no CFC, HCFC, or HFC

  • Contains no formaldehyde

  • Can be recycled

Strength and Thermal Performance

Cost effective thermal design is among the highest priorities in construction. EPS insulation products are available in a range of densities necessary to provide both, thermal resistance (R-value), structural integrity, and cost effectiveness. Other rigid insulation products fail to provide this design flexibility due to limited density availability, and therefore EPS provides optimum value when compared to other rigid insulations of the same R-value design.

Exposure to Water and Water Vapor

The mechanical properties of EPS are unaffected by moisture. Exposure to water or water vapor does not cause swelling. If condensation occurs within a system due to design and end-use conditions, full thermal efficiency is restored upon drying.

Tested for Home Insulation and Used By

EPSMA, NAHB, NRCA, AlA, SIPA, ICFA, SPRI

Biological Resistance

EPS provides no nutrient value to plants, pests, and microorganisms, thereby averting mildew, decomposition, or any bacterial and fungal proliferation.

Temperature Exposure/ Flame Retarding

The maximum recommended use temperature for EPS is 200F (75C). The self extinguishing properties of our EPS provide an important margin of safety, all EPS products must be considered combustible. Tests have demonstrated that the byproducts of combustion for EPS are carbon monoxide and carbon dioxide, and at concentrations far less than those given off by equal volumes of wood products.

Thermal Barrier

The term “thermal barrier” refers to a fire resistant covering or coating which separates EPS from the building interior. Commonly used thermal barriers, all subject to building code approval, include gypsum board, gypsum or cement plasters, perlite board, spray-applied cellulose, mineral fiber or gypsum coatings, and select ply woods.
