MOISTURE PROTECTION

Vapour Barrier

Professional vapour barrier installation to protect your building from moisture damage, improve energy efficiency, and maintain a healthy indoor environment.

Why Install a Vapour Barrier?

A properly installed vapour barrier is essential for protecting your building from moisture-related issues that can compromise structural integrity and indoor air quality.

Moisture Control

Prevents water vapour from penetrating walls, floors, and ceilings, reducing the risk of condensation, mold, and structural decay.

Improved Indoor Air Quality

Reduces humidity levels and prevents mold growth, creating a healthier living and working environment for occupants.

Energy Efficiency

Helps maintain consistent indoor temperatures by preventing moisture-related heat loss and protecting insulation performance.

Structural Protection

Prevents rot, corrosion, and deterioration of building materials, extending the lifespan of your property.

Pest Deterrent

Creates a barrier that helps discourage insects and rodents from entering wall cavities and crawl spaces.

Versatile Application

Effective for basements, crawl spaces, walls, floors, and commercial buildings — both new construction and retrofits.

Vapour Barrier Materials

We use high-quality vapour barrier materials designed for durability and maximum moisture protection.

POLYETHYLENE SHEETING

Polyethylene Vapour Barrier

Durable, flexible, and cost-effective. Polyethylene sheeting is the most common vapour barrier material, available in various thicknesses for different applications.

  • Excellent moisture resistance
  • Available in 6 mil, 10 mil, and 15 mil thickness
  • Ideal for crawl spaces and basements
  • Easy to install and repair
SPECIALTY BARRIERS

Advanced Vapour Barriers

For demanding applications, we offer advanced vapour barrier solutions including foil-faced, reinforced, and self-adhering products designed for specific environmental conditions.

  • Foil-faced barriers for radiant heat reflection
  • Reinforced barriers for high-traffic areas
  • Self-adhering membranes for seamless installation
  • Breathable barriers for specific climate zones

KNOWLEDGE BASE

Frequently Asked Questions

Quick answers about vapour barrier installation.

A vapour barrier is a material that resists the diffusion of moisture through walls, floors, and ceilings. It's essential for preventing condensation, mold growth, and structural damage. In Edmonton's climate, vapour barriers are particularly important in basements, crawl spaces, and exterior walls to protect against moisture infiltration.
The required thickness depends on the application. Standard residential applications typically use 6 mil polyethylene. For high-traffic areas or commercial applications, 10 mil or 15 mil may be recommended. We'll assess your specific project and recommend the appropriate thickness for optimal protection.
The installation time depends on the size and complexity of the area. A typical basement or crawl space can be completed in 1–2 days. We provide a clear timeline during your estimate so you know what to expect.
No, they serve different purposes. Insulation reduces heat transfer, while a vapour barrier controls moisture movement. However, they often work together. Closed-cell spray foam, for example, acts as both insulation and a vapour barrier. In many cases, we recommend combining both for maximum protection and efficiency.
