Vapor Barrier

A vapor barrier is an important component in building construction. Its purpose is to help prevent water vapor from reaching a building’s walls, ceilings, attics, crawl spaces or roofs, where it can condense and cause building materials to rot or grow mold. Protect your property or building project with one of our vapor barriers from Aluf Plastics, Insul Barrier, Insul-Tarp and Viper. Browse our range of poly sheeting, radiant barrier, vapor barrier and waterproofing below.

To protect your crawl space(s), you should consider products like the Insul-Barrier Crawl Space Vapor Barrier, which provides a thermal break and moisture barrier, or the Viper CS Pier Wrap, which is makes vapor barrier installation for piers and pipes in crawl spaces simple. Another great product for pipes is the Viper Vapor Patch, which is a vapor barrier pipe boot/patch that has been designed specifically for pipe penetrations and patch work.

For an under-slab vapor barrier, we have great products like the Viper II Underslab Vapor Barrier and the Viper Venom Barrier, which protect against damage from water vapor and soil gas that can threaten the indoor air quality. The Insul-Tarp Under-Slab Insulation is a brilliant option for preventing moisture and mold from ruining your building work. To protect from moisture and dirt during your project, you may also like the Aluf Plastics Poly Sheeting.

Key Products: Various ALUF PLASTICS Poly Sheeting Poly sheeting by ALUF PLASTICS provides a versatile and budget-friendly vapor barrier solution across an array of applications, including temporary partitions, coverings, or as a reliable vapor barrier in walls and roofs. Available in various sizes and thicknesses, these sheets flexibly cater to both small-scale and industrial-sized requirements.

Guidance on Product Selection

Understanding Thickness and Application

Consider the thickness (measured in mils) and the specific application of a vapor barrier. Crawl space barriers might necessitate a thicker material compared to wall applications due to direct ground contact. Ranging from 6.5 mils to 20 mils, discerning the right thickness is crucial for optimum performance and durability.

Evaluating Climate and Location

Acknowledge the climate and geographic location, as regions with higher humidity levels or more drastic temperature fluctuations may demand a vapor barrier with advanced moisture-resistant properties.

Budgetary Considerations

While deciding, it's essential to balance between budget and necessity. Heavy-duty and specialized vapor barriers are an investment, while poly sheeting might offer a more cost-effective solution for less demanding applications.

Standards and Codes

Ensure that selected vapor barriers comply with local building codes and standards, considering the Class (A, B, or C) which is indicative of permeability, and determining its aptness for your project.

Navigating through our extensive selection of vapor barriers, each product adhering to quality and performance standards, Roofing4Us is committed to furnishing you with solutions that shield your spaces against harmful moisture, ensuring structural longevity and enhanced living quality. We invite you to explore, compare, and select the perfect vapor barrier tailored to your requirements right here.
