TYPE: FIBERGLASS DUAL DENSITY INSULATION
DESCRIPTION
Tuf-Skin dual-density fiber glass blankets are 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 provides effective thermal and acoustical control in air conditioning and heating equipment.
Advantage.
The porosity and inherent structure of the flame-attenuated glass fiber blankets are highly effective in
reducing thermal transfer.
Tuf-Skin readily withstand damage from mechanical abrasion during assembly and from air erosion in service.
