Comparison of Air Barrier Membranes: Blueskin VP100, Aeromax R2, Lastobond Shield HT, and Tyvek HomeWrap
When constructing or renovating a building, choosing the right air and vapor barrier membranes is crucial for ensuring the structure’s durability and energy efficiency. In this blog post, we’ll take a closer look at four air barrier membranes widely used in Canada: Blueskin VP100, Aeromax R2, Lastobond Shield HT, and Tyvek HomeWrap. By comparing their technical properties, ease of installation, water vapor permeability, and value for money, we can determine which solution best suits Quebec’s climate.
Properties and Installation
- Blueskin VP100:
A self-adhesive membrane that sticks across its entire surface to completely block air. It requires a clean surface and a minimum temperature for proper installation.
- Aeromax R2:
A non-adhesive polypropylene membrane that attaches mechanically. It’s ideal for large walls and is less sensitive to the condition of the substrate.
- Lastobond Shield HT:
A self-adhesive membrane made of modified asphalt that bonds on its own. It’s primarily used on roofs due to its excellent heat resistance.
- Tyvek HomeWrap:
A non-adhesive membrane that allows water vapor to pass through easily, making it a great choice for exterior walls where moisture needs to escape.
Water Vapor Permeability
- Blueskin VP100: 33 perms – good for a self-adhesive membrane.
- Aeromax R2: 129 to 196 US perms – excellent for allowing moisture to escape from walls.
- Lastobond Shield HT: 0.02 perms – acts almost as a complete vapor barrier.
- Tyvek HomeWrap: 54 to 56 perms – well suited for the Quebec climate.
Price and Availability
- Blueskin VP100: More expensive but highly effective at blocking air.
- Aeromax R2: Offers excellent value, especially for larger projects.
- Lastobond Shield HT: The priciest option, but perfect when vapor blocking is a priority.
- Tyvek HomeWrap: Affordable and performs well across various types of projects.
Our Recommendation for Quebec’s Climate
After evaluating the technical properties, ease of installation, water vapor permeability, and overall value of these air barrier membranes, our top pick is the Aeromax R2 membrane. To optimize its performance, we recommend combining it with hemp insulation batts.
Here’s why:
- Efficient Moisture Management: Aeromax R2 allows moisture to escape easily from walls, reducing the risks of condensation and mold.
- Weather Resistance: Both the Aeromax R2 and hemp insulation are well-suited to withstand Quebec’s challenging climatic conditions.
- Eco-Friendly Insulation: Hemp is a natural insulator, contributing to the building’s overall ecological sustainability.
- Labor Savings: The quick installation of Aeromax R2 can help lower labor costs.
In summary, for building or renovating in Quebec, pairing the Aeromax R2 air barrier membrane with hemp insulation batts offers, according to our team of experts, the optimal solution to keep your building dry, well-insulated, and comfortable all year round.
