Import Best Waterproof Insulation House Wrap For Houses — Buy in wholesale FOB from Supplier in China

This waterproof insulation house wrap is a breathable membrane engineered for residential building envelopes. The material delivers excellent air tightness, which reduces convective heat loss and improves overall building energy efficiency. Water tightness is a core performance attribute, with the wrap forming a protective barrier against water vapor and rainwater ingress. The product also offers breathability, allowing water vapor within the wall assembly to escape and preventing condensation-related moisture damage. Durability is emphasized by the supplier as a means of maintaining stable thermal insulation performance over the building lifespan.

The membrane is typically manufactured from polypropylene or polyethylene-based nonwoven composites, though the supplier does not specify exact substrate composition. Standard house wrap products in this category commonly achieve water resistance ratings of A or B per ASTM E2556, with typical water vapor permeance values ranging from 5 to 50 perms (ASTM E96). The air permeance is typically measured per ASTM E2178, with quality membranes achieving less than 0.004 cfm/ft² at 1.57 psf differential pressure. UV resistance is another standard industry parameter, with typical exposure limits of 30 to 120 days before permanent cladding installation.

Primary applications include wood-framed residential construction, light commercial buildings, and renovation projects where existing envelope performance needs improvement. Buyers include construction contractors, building material distributors, and project developers targeting energy code compliance. The supplier, Fan Fei (Beijing) Energy-Saving Technology Co., Ltd., operates from Beijing with production or distribution facilities in the Pinggu District. Response rate data is currently showing zero percent, so buyers should expect to initiate contact and confirm current production capacity, standard roll dimensions, and minimum order quantities directly with the company.

Fan Fei (Beijing) Energy-Saving Technology Co., Ltd. is located at Beitun Village, Shandongzhuang Town, Pinggu District, Beijing, 100000, China. The company holds a harbor trust tier on the listing platform, which represents a baseline verification level. The response rate is recorded at 0.00 percent with zero average response hours, indicating that the supplier has not engaged with buyer inquiries through the platform's tracking system. This signal does not indicate business closure but does mean buyers should use direct outreach rather than expecting rapid platform-mediated responses.

The supplier's product focus centers on energy-saving building materials, specifically this waterproof insulation house wrap designed for air sealing, moisture management, and thermal performance improvement. The source description emphasizes three engineering priorities: air tightness, water tightness, and breathability working in combination to protect insulation and reduce energy loss. No information is provided about factory size, year of establishment, annual output, employee count, export markets served, or specific certifications held. Buyers should verify ISO 9001 quality management status, any ASTM or EN standard testing reports, factory audit records, and actual production capacity when initiating discussions.
