W.R. Meadows, a family-owned construction products manufacturer founded in 1926 and best known for its SEALTIGHT concrete and waterproofing lines, entered commercial roof restoration with the KNIGHTSHIELD silicone roofing system. The line pairs the FM-Approved KS-5100 high-solids 100% silicone field coating with walk-pad coating, flashing and self-leveling sealants, adhesion primer, and granules, installed by approved applicators as a fully warrantable system and sold through the company's national network of construction-product distributors.
