Vapour Barrier

A vapour barrier (also called a vapor retarder) is a material used to prevent moisture from passing through walls, ceilings, or floors. Its main function is to control the movement of water vapor inside a structure, which helps reduce condensation and mold growth. Moisture can travel as vapor from warmer areas to cooler areas, and if it condenses inside walls or insulation, it can cause rot, mold, and reduced energy efficiency. Vapour barriers are installed to block or slow down this process.

Benefits of Vapour Barriers

✅ Prevents Moisture Damage

Vapour barriers block moisture-laden air from entering wall cavities and insulation. This prevents condensation that could otherwise lead to rot, mildew, and costly repairs.

✅ Mold & Mildew Prevention

By keeping moisture out of enclosed spaces, vapour barriers reduce the risk of mold and mildew growth. This is essential for maintaining a healthy indoor environment, especially in humid areas.

✅ Improves Energy Efficiency

Dry insulation performs better than damp insulation. Vapour barriers help maintain insulation’s full thermal resistance (R-value), reducing heating and cooling costs over time.

✅ Extends Building Life

Moisture can weaken wood, drywall, and other structural components. Vapour barriers protect these materials from long-term damage, helping your building last longer.

✅ Better Indoor Air Quality

Moisture issues can cause mold and allergen buildup inside your home or building. A vapour barrier helps control these problems, improving the air you breathe every day.
