Introduction

We exported more than 1000*40HQ of R3.5 fiberglass insulation batts to Australia in 2009. Their government requires the thickness no less than 150mm, or else hard to reach the R value 3.5. The reason please make reference to our blog article: key factor to reach R value 3.5.

EcoIn glass wool batts are lightweight fiberglass batt insulation rated R3.5, designed for residential and commercial wall, roof and floor cavities. With density 10–16 kg/m³ and thickness 150–180 mm, they achieve a thermal conductivity of 0.034–0.062 W/m.K and a Class A1 non-combustible fire rating per GB 8624-2012, making them suitable for timber frame, steel frame and dry wall construction.

Glass Wool Batts: FAQ

EcoIn glass wool batts are engineered to meet Australian R3.5 thermal requirements. According to Wikipedia, glass wool is an insulating material made from fibres of glass arranged with a binder into a texture similar to wool. Our products are exported to Australia, New Zealand and Southeast Asia.

What R-value do EcoIn glass wool batts achieve?

EcoIn glass wool batts achieve R3.5 thermal resistance, meeting Australian building energy codes requiring minimum 150 mm insulation thickness for residential roofs and walls. The R3.5 value is achieved with density 10–16 kg/m³ and thickness 150–180 mm, giving thermal conductivity 0.034–0.062 W/m.K. Browse our glass wool blanket for roll-form alternatives.

What are the dimensions of glass wool batts?

Standard R3.5 fiberglass batts from EcoIn measure 1160×430 mm with thickness 150–180 mm and nominal density 10–16 kg/m³. Fiber diameter is 5–8 μm and moisture absorption is ≤5% by volume per GB/T 16400-2003. Custom sizes and densities are available on request for specific project requirements.

Where are glass wool batts used?

These insulation batts are primarily used for wall cavity and roof insulation in timber frame and steel frame residential buildings. They are the standard R3.5 batt specification in Australia and New Zealand. They are also suitable for HVAC duct lining, acoustic ceiling panels, floor insulation in subfloor cavities, and industrial thermal insulation in boilers and machine rooms.

What fire rating do glass wool batts have?

EcoIn R3.5 fiberglass batts achieve Class A1 non-combustible reaction-to-fire classification per GB 8624-2012. The inorganic glass fibre construction does not sustain combustion and produces no toxic smoke. This fire performance makes glass wool batts compliant for use in party walls, roof spaces and other fire-rated assemblies required by building codes.

How do I order glass wool batts from EcoIn?

Specify your required R-value (R3.5), density (10–16 kg/m³), thickness (150 or 180 mm), standard size (1160×430 mm) or custom dimensions, and project quantity. EcoIn ships your order within 7–10 days. Payment via TT, LC, Western Union, Bitcoin, or Trade Assurance. Submit an inquiry for your glass wool batts project today.
