AlphaGyp Floor Underlayment

AlphaGyp Floor Underlayment is a high-strength, gypsum-based floor underlayment designed for multifamily, hospitality, commercial, and mixed-use construction. Installed as a pumpable underlayment system, AlphaGyp provides a smooth, durable surface that readily accepts a wide range of finished floor coverings while helping improve sound control and fire-resistance performance.

Engineered for use over wood-frame and concrete floor assemblies, AlphaGyp creates a flat substrate that supports efficient installation and long-term flooring performance. The system is commonly specified in apartments, condominiums, hotels, student housing, senior living communities, office buildings, and other projects where sound attenuation, fire ratings, and floor flatness are critical.

AlphaGyp is compatible with numerous UL listed floor-ceiling assemblies and can be used over radiant heating systems in accordance with project specifications. Installed by trained applicators, it delivers reliable performance, predictable results, and a strong foundation for today’s demanding construction projects.
