Baymont uses only sanitary high-grade gloss polyester gelcoat- reinforced with composite matrix. The finish- Baymont Sanitary White- is a proprietary color containing UV and mold inhibitors. The 3" legs are built into the design for stability; a ridge trim protects the Apron and eliminates shoe molding. Baymont does not use cardboard or other undesirable structural materials. Units are constructed of polyester resins and strand glass only. Bottoms are constructed of A-Grade 7/16 OSB for better adhesion and stronger foundation. Certifications: ANSI Z124.2
