SitaTrendy Insulated Rainwater Outlets

SitaTrendy rainwater outlets are a robust polyurethane cast construction providing thermal insulation from the surrounding structure which prevents the build-up of condensation to the underside. Units are either factory sealed to a 495 x 495mm connection flange for direct compatibility with Radmat waterproofing systems or provided with a clamping-ring arrangement for mechanical connection to the surround waterproofing system. For cold-applied liquid waterproofing systems the membrane is bonded directly onto the polyurethane outlet body.
