DESCRIPTION
®
Tuf-Skin dual-density fiberglass insulation is the most widely-used insulation for HVAC equipment applications. The
combination of high-density skin and low-density core provides high acoustical values in the high and low frequency
ranges normally encountered in HVAC equipment.
®
Application. Tuf-Skin
Advantage. The porosity and inherent structure of the flame-attenuated glass fiber blankets are highly effective in
reducing thermal transfer.
®
Tuf-Skin readily withstands damage from mechanical abrasion during assembly and from air erosion in service.
