Insulated Concrete Curing Blanket 4-Layer – 12'x20′

The 4-Layer Concrete Curing Blanket in the 12-foot by 20-foot size is a premium insulated cover designed for concrete curing, cold-weather protection and site material shielding. Built with a four-layer cross-woven polyethylene outer shell and multiple closed-cell foam insulation layers, this silver-coloured blanket is engineered to retain heat, limit wind-chill, preserve moisture and support proper concrete strength gain even in challenging weather conditions.

It’s ideal for use when pouring slabs or flatwork in cooler temperatures, or when you need to cover larger areas with job-site insulation to control curing conditions.

• Four layers of insulation – This version features a high-density structure: cross-woven outer shell, high-density closed-cell foam, additional polyethylene layer and multiple foam layers for enhanced thermal retention.
• High R-value performance – The construction is rated at roughly R ≈ 3.35 (or R1.67 with 3-in air space) according to vendor specifications, helping concrete cure more efficiently in colder conditions.
• Durable, job-site tough – Built to resist tearing, water penetration, UV exposure and mildew thanks to reinforced hems, robust fabric layers and closed-cell foam core.
• Large-area coverage – At 12′ × 20′ (≈ 240 sq ft) this blanket allows you to cover significant slab sections with fewer blankets, saving time and reducing seams.
• Silver colour for visibility and reflectivity – The silver outer layer is easy to spot on the site and may reflect solar gain, helping maintain temperature under the blanket.
• Multipurpose usage – While optimized for curing concrete, it can also be used for thawing frozen ground, covering materials, protecting sensitive equipment from cold exposure, or as a general job-site insulation tarp.

• Ideal for cold-weather placements of concrete slabs, such as driveways, patios, warehouse floors or foundations when ambient temperatures are low and early strength gain is critical.
• Suitable for overnight protection of freshly poured flatwork, preventing rapid cooling, wind chill or moisture loss.
• Works for temporary ground thawing or pre-heating hard ground prior to pour.
• Handy for material protection, such as covering sand or aggregate stockpiles, insulation of job-site storage, or covering equipment during cold or wet weather.
• Appropriate for residential, commercial or industrial flatwork where controlling curing conditions helps ensure quality and durability of the concrete.
