When installed in accordance with instructions, so that compression is controlled, the product provides specified thermal performance. Operating costs are controlled due to reduction of heat loss or gain through sheet metal duct walls.
Product is easy to cut to fit flat, curved or irregular side surfaces for a neat, thermally effective insulation.
Dhumal provides a variety of specifications for customers. Users can choose different density and surface according to their own needs.
There are several factors which impact condensation control: environment temperature, vapor barriers, operation temperature, width and thermal conductivity of insulation.
Dhumal offers all kinds of solutions for different regulations or standards. To make it more energy-efficient, please contact our sales department.
