Bradford WindMaster™ & WindMaster BAL Roof Ventilator
WindMaster is a wind-driven roof ventilator that helps exhaust air from roof spaces without using electricity. Made from lightweight aluminium, it reduces heat load and moisture in the roof cavity, helping to create a healthier home with no running costs.
