Below are questions buyers ask us most about R value fiberglass insulation. For a technical overview of thermal resistance, see the Wikipedia article on R-value.

EcoIn R value fiberglass insulation is available from R-11 to R-38, covering standard batt, roll, and board formats. The R value fiberglass batt thickness ranges from 89 mm (R-11) to 267 mm (R-38), with facings including kraft paper (FSK), aluminium foil, and unfaced options. Custom R-values and thicknesses can be produced for OEM orders.

Yes. EcoIn R value fiberglass insulation carries a Class A1 non-combustible rating under ASTM E136 and EN 13162. It does not spread flame or produce significant smoke, making it compliant with IBC and local residential building codes. Fire test certificates and material safety data sheets are available on request.

R value fiberglass insulation is used primarily in exterior walls, attic floors, and roof assemblies of residential and light commercial buildings. It is also suitable for HVAC duct wrapping, steel-structure wall panels, and modular building insulation. Choose higher R-values (R-30 to R-38) for cold climates and attic applications where heat loss is greatest.

Each roll or batt of R value fiberglass insulation is vacuum compressed and wrapped in polythene film, reducing shipping volume by up to 40%. Standard lead time is 7–15 days.
