Crawl space liners are not just simple sheets of plastic; they are engineered solutions designed to meet specific environmental and structural challenges. Here’s what sets them apart:
Moisture Control: By creating a barrier against ground moisture, liners prevent water vapor from entering the crawl space, which can lead to wood rot, mold, and increased energy costs.
Thermal Regulation: A quality liner contributes to insulation, helping maintain consistent temperatures and reducing HVAC strain.
Air Quality Improvement: By blocking allergens, radon gas, and mold spores, liners improve indoor air quality—a critical aspect for homes with HVAC systems located in crawl spaces.
Unlike generic plastic sheets sold in big-box stores, professional crawl space liners are engineered with advanced materials and designed for long-term performance. Key features include:
High-quality crawl space liners are typically made of polyethylene, reinforced polyethylene, or multilayered engineered plastics. These materials offer:
High Tensile Strength: To resist tearing during installation or due to shifting ground.
Puncture Resistance: Prevents damage from sharp rocks or debris.
UV Stability: Essential for outdoor or partially exposed crawl spaces.
Crawl space liners range in thickness from 6-mil to 20-mil. While thinner options may suffice for basic applications, thicker liners like 20-mil are better suited for heavy-duty or encapsulation projects due to:
Enhanced durability.
Greater resistance to wear and tear.
Improved moisture blocking capabilities.
Reinforced liners contain a polyester or fiberglass scrim layer sandwiched between polyethylene sheets. This reinforcement adds structural integrity, making the liner less prone to punctures and ensuring a longer lifespan.
Many professional-grade liners meet ASTM fire safety standards. Fire-retardant liners are critical in applications where fire hazards exist, such as near electrical wiring or in commercial settings.
Quality crawl space liners meet or exceed industry standards, such as:
ASTM E1745: Ensures liners are suitable for use as vapor barriers.
Class A Fire Ratings: Critical for fire safety compliance.

All GPS products are made from premium-grade materials that are:
Puncture-Resistant: Withstand tough installation conditions.
Moisture-Blocking: Effective in controlling vapor and preventing water damage.
Durable: Designed to last 20+ years with proper installation.
Choosing GPS means supporting American manufacturing. Their products adhere to strict quality standards and compliance with U.S. regulations, offering peace of mind that the liner you’re installing is reliable and safe.
From standard liners to reinforced and fire-retardant options, GPS provides products that meet diverse needs, including:
High-traffic crawl spaces.
Areas with extreme moisture.
Projects requiring fire-resistant materials.
Contractors and crawl space companies consistently rely on GPS for their projects. Their reputation for excellence has made them a go-to supplier for high-quality liners that deliver results.
Big-box store liners may be inexpensive, but they lack the durability and engineering required for long-term performance. These products often:
Tear easily during installation.
Fail to block moisture effectively.
Require frequent replacement, adding to long-term costs.
Choosing a liner that is too thin can lead to premature failure. For encapsulation projects or high-moisture areas, a 20-mil liner is the best choice.
In spaces where electrical wiring or flammable materials are present, using a fire-retardant liner is crucial. Non-compliant liners can pose serious safety risks.
Selecting the right liner requires understanding your specific crawl space conditions. Consulting with experts like GPS ensures you get the right product for your needs.
Installing a crawl space liner is a big job, but it’s worth doing correctly. Here are the steps:
Preparation:
Clear debris and level the ground.
Repair any existing water leaks or structural issues.
Measurement and Cutting:
Measure the crawl space dimensions accurately.
Cut the liner to fit, allowing for overlaps.
Sealing:
Use waterproof tape to seal overlaps and edges.
Secure the liner to walls and piers with adhesive or fasteners.
Inspection:
Check for gaps or loose sections to ensure complete coverage.
By using a high-quality liner from GPS, you’ll avoid the frustration of poor performance or premature failure.
Generic sheets lack the engineering required to block moisture effectively and withstand the conditions of a crawl space. Professional liners are designed for durability, moisture resistance, and compliance with safety standards.
With proper installation and maintenance, GPS liners can last 20 years or more.
Thicker liners (like 20-mil) offer greater durability and moisture resistance, making them ideal for high-moisture areas or heavy-duty applications.
Yes, but professional installation ensures optimal sealing and performance, especially for large or complex crawl spaces.
Yes, GPS liners are designed with sustainability in mind, offering long-lasting performance that reduces waste over time.
Outfitting your crawl space with a high-quality liner is a significant investment in your home’s safety, energy efficiency, and structural integrity. By choosing Global Plastic Sheeting, you’re not just buying a product—you’re gaining access to expertise, superior materials, and a proven track record of success.
