Underlayment is a thin layer of material installed between the structural subfloor and the finished flooring in a building. An ideal underlayment material, such as gypcrete, should offer soundproofing capabilities, fire resistance, and a durable surface. These features promote comfort and safety in residential and commercial construction projects. Here are several different types of underlayments:
1. Gypcrete Underlayments
Gypcrete underlayments are self-leveling compounds made from gypsum, sand, and concrete. They set quickly to create a smooth finish and can be enhanced with moisture-resistant coatings for added durability. This lightweight material has soundproofing capabilities and is suitable for use in multi-story homes and apartment buildings. Gypsum concrete underlayments also have a durable, crack-resistant surface. They offer structural support, a seamless texture, and a fire-resistant layer, making them ideal for indoor use.
2. Cementitious Leveling Underlayments
Cementitious leveling underlayments (CLUs) have high adhesion strength, a smooth surface, and rapid setting abilities. These durable underlayments are easy for trained applicators to apply without troweling. The surface preparation for CLUs is straightforward, and the material may help dampen vibrations. This crack-resistant compound is a low-density option with high compressive strength, making it suitable for supporting heavy items like furniture and industrial equipment. CLUs can also be customized in thickness to address specific indoor or outdoor applications and eliminate concrete surface imperfections.
3. Radiant Heating Underlayments
Radiant heating underlayments are specifically designed for use with heated floor technology. These materials distribute heat evenly and are compatible with a variety of flooring types. Choose radiant heating underlayments that provide efficient heat transfer, thermal insulation, and support for underfloor heating systems. With a low-profile installation, these underlayments can also support hydronic heating. Key benefits include potentially reduced heating costs, minimal shrinkage, and the capability to securely support embedded heating cables or tubing.
4. Sound Control Mats
Sound control mats help with noise reduction and acoustic isolation. These underlayment mats reduce the effects of impact sounds and provide soundproofing for private spaces like bedrooms, home theaters, and offices. They are particularly effective in multi-story buildings, where footstep noise and other impact sounds can be disruptive. Sound control mats may be installed beneath flooring materials such as hardwood, laminate, vinyl, and tile, helping to absorb and dampen sound vibrations. The resilient material is ideal for heavy-duty performance and provides flexible applications ranging from residential to commercial spaces.
5. High-Strength Underlayments
High-strength underlayments are designed for heavy-duty applications and increased load-bearing capacity. These underlayments provide a strong base that reinforces concrete and helps prevent cracking. The high-performance formula offers high-quality impact resistance, creating a durable surface finish. These features make the material suitable for corrugated metal decking projects. The underlayment provides a smooth, stable, and load-bearing foundation for the final flooring system.
