Spray-Application of Aluminum Coating over Rust-Primed and Sealed Metal Roof in La Grange MD

Featured Project – Thermcraft Thermal Equipment, Winston Salem NC, White Elastomeric Coating System

Like many industrial facilities, the Thermcraft facility in Winston Salem NC is part air-conditioned in their office and part non-air-conditioned in their back warehouse. Their facility was riddled with persistent widespread leaking, around fasteners, ridge cap seams, field horizontal seams, wall rake seams, and around penetrations. There was one seam transition where they had tried repeatedly to seal but had been unsuccessful due to using the wrong materials and methods. They were also interested in reducing interior temperatures for worker comfort and reducing air conditioning related energy costs in the front office section.  Read More
