Breathable Roof Membrane

House Dress Jinbo breathable roof membrane is self-developed and mass-produced by Xiashi Packing, serving as a dedicated energy-saving, damp-proof auxiliary material for building wall and roof systems. We support one-stop bulk supply of full matching accessories: vapor barrier films, sealing butyl tapes and anti-condensation felts. Our goods have been widely supplied to landmark construction projects, large stadium venues, BASF production bases and Starbucks factory buildings, and we welcome project purchasers, distributors and construction firms to place bulk inquiries.

What is Breathable Roof Membrane?

Also called building breathable underlayment, breathable roof membrane is a functional construction material laid outside building thermal insulation layers. When matched with vapor barrier films, it forms a complete moisture management system for buildings, and bulk buyers can order the whole system as a combined package.

It adopts micro-pore physical separation technology to realize selective permeability: liquid rain droplets (around 20 microns) are blocked by surface tension and cannot seep through the sheet, while tiny water vapor molecules (only 0.0004 microns) inside walls and insulation layers escape smoothly outwards. This design realizes external waterproofing and internal moisture discharge at the same time.

The built-in S embossed texture strengthens the sheet’s toughness and anti-shrink capacity, lowering breakage rate during on-site installation and cutting construction loss for builders.

This product owns three core advantages: tight air lock, reliable waterproof effect and long-lasting vapor permeability. Its windproof sealing structure cuts building HVAC energy consumption by nearly 40% to lower long-term operation costs for project owners. Premium waterproof performance stops rain infiltration and protects insulation layers from damp failure. Its moisture permeability reaches 1000 g/m²·24 h, continuously draining trapped moisture inside building envelopes to stop wall mildew and metal roof condensation corrosion.

It delivers stable weather resistance, staying intact without cracking under -30°C low temperature, plus strong UV resistance. The product holds official national construction material inspection certifications, and wholesale orders come with complete test document packages. It works perfectly for metal roofing, tile roofing, light steel wall panels, stone curtain walls and stucco exterior walls. We supply full supporting fittings including butyl sealing tapes and water stop strips for one-stop procurement, suitable for all types of domestic and overseas engineering projects. We accept custom width, length and packaging for bulk buyers, and offer fast lead time for large project orders.

We supply all needed items in one package: breathable roof membranes, vapor barriers and assorted sealing parts. The full set works for all wall and roof building types.

Full Global Certifications

Every batch comes with official third-party test papers. The products meet international standards including Australian building codes and BBA requirements, easy to pass overseas project audits.

Self-owned Factory & Rich Project Experience

We run our own production plant with steady large-volume supply. Our materials have been used on many major builds, including sports venues and overseas-funded factory sites.

Full Construction Assistance

We provide unified construction guidance plus full matching accessories. This helps construction teams cut waste and lower overall project spending.

Practical examples of breathable roof membranes

Large Sports Venue Metal Roof

We delivered a full dual-film system for a 12,000-square-meter metal roof of large sports venues, a great option for engineers purchasing complete building envelope materials. Paired breathable membrane and vapor barrier stop interlayer condensation entirely, cutting heating and cooling energy use by 40% while keeping stable long-term insulation. Clients placing large project orders can get all matching auxiliary parts in one package.

BASF & Starbucks Factory Wall Works

This 8,600 sqm wall project operates under high humidity, a representative reference for factory construction buyers. Our breathable roof membrane prevents wall mold, boosts air-layer insulation efficiency by 43% and lowers daily air conditioning costs significantly. Construction teams ordering for new factories or plant retrofits will receive full official test documents with bulk shipments.

Australian Light Steel Villa Development

We shipped 360 standard-compliant rolls for local villa builders, fully meeting Australia’s construction codes. The material resists UV rays and freezing temperatures, cutting building energy loss by 35% and reducing construction waste by 15% to keep overall project expenses down. Custom roll widths and quick production turnaround are offered for international villa bidding projects.

Commercial Complex Stone Curtain Wall

Our membrane system was installed on 7,200 sqm external stone curtain walls of this commercial complex, with zero water seepage observed through repeated rainy seasons. It cuts heat loss of building envelopes by 30% and slashes long-term exterior wall maintenance fees by 40%, a budget-friendly choice for commercial property buyers with big order volumes.

Residential Community Roof Works

We supplied matched vapor barrier and breathable membrane packages for a 15,000 sqm residential roof project. Years after completion, the roof remains leak-proof with no trapped internal moisture, sustaining reliable indoor thermal performance all year. Property developers and construction tenderers can purchase this integrated moisture management system for large-scale housing developments.

FAQs

What is the working principle of breathable roof membrane?

It adopts micropore technology. Water droplets cannot penetrate due to surface tension, while water vapor inside the building can escape freely, realizing waterproof & vapor permeable performance.

What’s the difference between breather membrane and vapour control layer?

Breather membrane is laid outside insulation to drain internal moisture; VCL is installed inside insulation to block indoor humidity. They need to be used together for full vapor management.

Can your products meet Australian Standard / BBA requirements?

We have complete official test reports and can provide documents to support overseas certification and project inspection.
