Borel Centrifugal Glass Wool Roll Felt
Other Products
The slender fibers within Bole'er centrifugal glass wool roll felt effectively partition air, impeding its flow and thereby restricting air convection, which constitutes the insulation principle of the roll felt. It is widely used for interior wall insulation in steel structure buildings, roof thermal insulation, and duct insulation for central air conditioning systems.
