Import Glasswool R3.5, R4.0 — Buy in Bulk from Supplier in China

Glasswool batts with R3.5 and R4.0 thermal resistance ratings from Hebei Ruida Import & Export Co., Ltd. are produced using the TEL fibreisation process, where molten glass is drawn into fine fibres and bonded with a thermosetting resin. The material is then cured to form a rigid or semi-rigid board, suitable for thermal insulation, sound absorption, and fire protection. The R-value indicates the product’s thermal resistance, with R3.5 and R4.0 being common specifications for residential and commercial building applications in regions like Australia, where compliance with AS/NZS 4859.1 is required.

The glasswool is non-combustible, emits no toxic fumes, and has a low moisture absorption rate, making it ideal for use in walls, ceilings, and floors. Standard dimensions include 1160 mm x 430 mm x 180 mm, 1160 mm x 580 mm x 160 mm, and 2000 mm x 1200 mm x 25/50 mm, with densities ranging from 10 kg/m³ to 48 kg/m³. The fibres have a typical diameter of ≤6 µm, contributing to the material’s high thermal efficiency and sound-absorbing properties. Variants with aluminium foil laminates are available for enhanced heat reflection and vapour resistance, particularly in high-temperature environments such as workshops or control rooms.

Hebei Ruida’s glasswool batts are widely used in construction, chemical, electronic, and energy industries for heat preservation, thermal insulation, and noise reduction. The product can be cut to size on-site to fit specific applications, such as sound reduction systems, refrigeration equipment, or domestic appliances. Each container typically holds 380-440 bags, with 16 batts per bag covering approximately 8-9 m². The supplier offers delivery to major Australian cities like Sydney, Melbourne, and Brisbane within 4-6 weeks, with a production capacity of 10x40HQ containers per day.

Hebei Ruida Import & Export Co., Ltd. is based in the Industry Park, Quan Village, Langfang, Hebei Province, China. The company operates within the harbor trust tier and specialises in the production and export of glasswool insulation materials. Its location in Langfang, a key industrial city near Beijing, provides logistical advantages for shipping to domestic and international markets, including Australia.

The supplier’s profile indicates a strong focus on glasswool products, including batts, boards, and pipes, with a production capacity of up to 300x40HQ containers per month. Hebei Ruida offers OEM services, allowing customisation of product dimensions, densities, and surface finishes to meet specific project requirements. While the response rate is not listed, the company’s detailed technical parameters and compliance with standards like AS/NZS 4859.1 suggest a commitment to quality and transparency.
