Materials and thermal insulation in work rain suits
The real effectiveness of work rain suits lies in the structure of the textile base and in the assembly technologies. Garments designed for intensive construction use abandon lightweight plastics in favour of robust polyester substrates coated with polyvinyl chloride (PVC) or polyurethane (PU). This construction guarantees complete impermeability to liquids while maintaining high mechanical resistance to abrasion against scaffolding and brickwork. A decisive construction detail for certification is the absence of traditional needle stitching, which would create preferential paths for water to seep in by capillary action: professional garments use only heat-taped or high-frequency welded seams. The standard kit of waterproof jacket and trousers must also include adjustable cuffs, front closures protected by a double storm flap and shielded back vents. The latter are essential to reduce the condensation caused by physical exertion, allowing body vapour to escape without compromising waterproofing.
