Vapour Barrier For Walls

The House Dress®Jinbo vapour barrier for walls produced by Xiashi Packing Co., Ltd. utilizes an ultra-dense molecular structure to effectively block the ingress of indoor moisture into the insulation system, thereby addressing the root causes of condensation, mold growth, and corrosion in building cavity spaces.

What Is House Dress Vapor Barrier for walls?

House Dress® Vapour Barrier for walls is a high-molecular composite polymer film independently developed by Xias Packaging Co., Ltd (founded 1984, Xiongan New Area). It acts as a critical vapour control layer (VCL) installed on the warm interior side of building insulation systems.

Unlike ordinary PE plastic films that fail under temperature swings, our product features ultra-low water vapour transmission rate ≤10g/m²·24h, significantly reducing indoor vapour penetration from penetrating insulation layers. Paired with House Dress breathable waterproof membrane (outer side), it creates a balanced "moisture control dual system": vapour locked inside by barrier, residual moisture discharged outward via breather membrane,helping prevent mold growth, insulation degradation and condensation-related issues when installed correctly.

Working Principle

Indoor warm humid vapour cannot pass through dense vapour barrier for walls micropores, avoiding trapped moisture between wall/roof layers that causes insulation failure, steel rust, timber decay and mold growth. Coordinate with outer breathable membrane to realize one-way moisture control for the whole building envelope.

FAQ

Q1: What’s the difference between vapour barrier for walls and breather membrane?

A: Vapour barrier for walls is installed on the warm interior side of insulation, to stop indoor humid vapour from entering insulation. Waterproof breather membrane is laid on exterior insulation surface, block rainwater while letting residual structural vapour discharge outside. The two must be used together for complete moisture control system.

Q2: Can it be used in high-humidity buildings like swimming pools?

A: Yes. Our ultra-low vapour permeability ≤10g/m²·24h effectively isolate heavy indoor moisture, prevent metal roof dripping water & insulation failure; matched anti-condensation felt can further reduce condensation dripping noise on steel panels.

Q3: Is OEM & private label acceptable?

A: Absolutely. We support custom roll width, thickness, printing your brand logo packing design, MOQ negotiable for global distributors.

Q4: What’s the delivery time & MOQ?

A: MOQ: 750 rolls standard; lead time 15-20 working days after deposit. Fast rush order available for urgent construction projects.
