The hot air roofing burner works with propane gas. It develops a hot airflow and it is used when open flames are not allowed or advisable. Thanks to the special vortex system of the burner, an air-gas combustion is created inside the steel head. This combustion produces a concentrated and powerful flame which gives a strong adjustable hot air flow, allowing for a quick heating of the material. This special torch is particularly suitable for the application of elastomeric (low-melting) membranes, for drying surfaces and also for speeding up the application of self-adhesive membranes (difficult to apply in cold and humid weather conditions).
