ANNOUNCING SUPER-FELT

. . the new lohns-Manville Rock Wool Batt

'ZA revolutionary new process, developed by Johns-Manville, produces a rock wool of long fibres. Scientifically felted, these long fibres result in a much stronger and. lighter-weight batt, with greater uniformity and rigidity throughout. Longfibre Saper-Felt sets a new high standard in home insulation.

Stper-Felt is so firmly felted it will not break down, even with rough handling. Improved handle-ability reduces cost of installation. Batts fit snugly between frarning members with less time and labor.

The same size package now contains lO batts instead of 8! This means 256 fewer packages to handle 25ft more material per truckload. Get the full story of this new development.
