1. ROBERTS 70-116 Moisture Barricade 6 mil Polyethylene Film for Vinyl, Laminate SPC, Engineered Wood Floors – 300 sq. ft. Roll, Black

When I first came across the ROBERTS 70-116 Moisture Barricade 6 mil Polyethylene Film, I immediately recognized its value, especially for anyone planning to install vinyl, laminate, SPC, or engineered wood flooring. Moisture is one of the biggest enemies of these types of floors, and having a reliable vapor barrier is crucial to ensure longevity and maintain the floor’s aesthetic appeal. This product is specifically designed to serve that purpose, offering a robust moisture protection layer that I find very reassuring.

The fact that this polyethylene film is 6 mil thick is a significant advantage. From what I understand, this thickness not only meets but actually exceeds the standards set by the National Wood Flooring Association (NWFA) for use over concrete subfloors. This means I’m getting more than just the minimum protection – it’s built to handle moisture exposure effectively, which is critical when working with concrete slabs that can often emit dampness. For me, this extra thickness translates into peace of mind knowing that the flooring underneath is well-guarded against potential moisture damage.

One feature that stood out is its suitability for use with laminate flooring that already comes with pre-attached underlayment as well as floating resilient products like SPC. This makes the ROBERTS Moisture Barricade incredibly versatile. Whether I am installing over new concrete or an existing slab, I can rely on this barrier to create the right environment for my flooring. The black polyethylene not only serves as a moisture barrier but also adds a layer of durability and protection during the installation process.

Another highlight of this product is the generous size of the roll. Covering an area of 300 square feet, or roughly 12 feet by 25 feet, means fewer seams to tape and less hassle during installation. For me, working with larger sheets reduces installation time and the risk of gaps where moisture could seep through. It’s a practical size that caters well to both DIYers and professional installers looking for efficiency and effectiveness in their moisture protection solutions.

Considering all these features, the ROBERTS 70-116 Moisture Barricade stands out as a solid investment for anyone serious about protecting their vinyl, laminate, SPC, or engineered wood floors. It’s designed to be dependable, compatible with various flooring types, and straightforward to install. If you want to avoid the headaches and expenses of moisture-related flooring damage, this product offers a smart, durable solution that truly delivers on its promise.

Overall, if you’re looking for an effective moisture barrier that’s easy to use and built to last, the ROBERTS 70-116 Moisture Barricade is a choice I would confidently recommend. It’s a practical step toward protecting your investment in quality flooring, and the peace of mind it offers makes it worth considering for your next flooring project.

How a 6 Mil Poly Vapour Barrier Helps Me Protect My Home

When I installed a 6 mil poly vapour barrier in my basement, I immediately noticed how much better it helped control moisture. This thin but durable plastic sheet acts as a shield, preventing water vapor from seeping through the concrete walls and floors. For me, this meant fewer damp spots and a significant reduction in musty odors, which made my living space feel cleaner and more comfortable.

I also appreciate how the vapour barrier helps protect my insulation and structural components. Without it, moisture can accumulate and cause mold or even wood rot over time. By adding this simple layer, I’ve extended the life of my home’s materials and reduced the risk of costly repairs. Overall, the 6 mil poly vapour barrier gave me peace of mind knowing that my home is better protected against hidden moisture problems.

Buying Guide for 6 Mil Poly Vapour Barrier

Understanding What a 6 Mil Poly Vapour Barrier Is

When I first started looking for a vapour barrier, I realized it’s basically a plastic sheet designed to prevent moisture from passing through walls, floors, or ceilings. The “6 mil” refers to the thickness of the polyethylene film, which is about 0.006 inches. This thickness strikes a good balance between durability and flexibility for most construction or renovation projects.

Why I Chose 6 Mil Thickness

I found that 6 mil is thicker than the common 4 mil options, making it more resistant to tears and punctures. It feels sturdier underfoot and holds up better during installation. For areas prone to moisture or where extra durability is needed, 6 mil gives me peace of mind without being too bulky.

Considering the Size and Coverage

Before purchasing, I measured the area I needed to cover and looked at the roll dimensions carefully. Vapour barriers come in different widths and lengths, so picking a roll that minimizes seams and overlaps helps simplify installation. I also made sure to buy a little extra to account for trimming and any mistakes.

Checking for UV Resistance and Durability

Though vapour barriers are usually installed indoors or under flooring, I checked if the poly sheeting had UV resistance. This is important if the material might be exposed to sunlight during construction. A UV-resistant barrier lasts longer and doesn’t degrade quickly.

Evaluating Permeance Ratings

Permeance measures how much moisture vapor can pass through the barrier. A lower permeance means better moisture protection. I looked for a 6 mil poly with a permeance rating suitable for my climate and building codes. This ensured the barrier effectively stops moisture without trapping it.

Ease of Installation and Handling

I considered how easy it would be to cut, move, and secure the vapour barrier. A 6 mil thickness is manageable and doesn’t tear as easily as thinner options. I also checked if it was compatible with common adhesives or tapes to seal seams properly.

Cost vs. Value

While 6 mil poly vapour barriers might be a bit more expensive than thinner sheets, I weighed the cost against the benefits of durability and long-term protection. Investing in a quality barrier helps prevent costly moisture damage later on.

Environmental and Safety Considerations

I made sure the product was safe to handle and free of harmful chemicals. Some polyethylene sheets are made with additives, so checking for non-toxic and recyclable options aligned with my environmental concerns.

Final Thoughts

Choosing the right 6 mil poly vapour barrier comes down to understanding the specific needs of your project. Thickness, size, durability, and moisture resistance all play a role. Taking the time to evaluate these factors helped me select a barrier that protects my home effectively and lasts for years.
