Product Information
Are you looking for an effective under-slab insulation and vapor barrier solution for your construction project? Insul-Tarp is a popular choice, designed to provide both thermal and moisture protection. Insul-Tarp is a multi-layer blanket insulation made from cross-woven polyethylene, high-density closed-cell foam, high-density polyethylene bubble layer, and two reflective aluminum layers. This combination of materials provides consistent thermal and moisture protection.
Pros:
Energy Efficiency: Insul-Tarp provides a thermal break and moisture barrier between the slab and grade, increasing energy efficiency. When used in radiant heated slab applications, it redirects heat back into the slab, reducing energy loss and improving overall system performance.
Mold and Degradation Prevention: Insul-Tarp controls water vapor migration, reducing condensation and the risk of mold growth beneath the slab. This contributes to a healthier indoor environment and helps maintain the integrity of the building structure over time.
Easy Installation: Insul-Tarp is easy to install, with the black outer layer facing down and appropriate tape used for sealing. Its flexibility allows for fitting around pipes, support columns, and irregular or curved slab edges.
Wide Range of Applications: Insul-Tarp is suitable for both residential and commercial projects, and can be used in various climate conditions, including cold climates. It can also be combined with other insulation materials if additional thermal protection is needed or required by local building codes.
Cons:
Care Required During Installation: While Insul-Tarp is designed to be puncture-resistant, care must be taken during installation to avoid damaging the material. Installers should avoid driving stakes through it, provide additional protection in high-traffic areas, and repair any punctures or holes with appropriate tape.
