Two decades ana thousands of deaths
af;er asbestos insulation was found to be a
killer, recent hejlth siudies suggest th.,i
certain other insulation products, some
tunes used as s.bstitutes for astestos. may
also present a urg cancer threat.

Makers of the materials under scrutiny J all defend their produrls1 safety. And re
searchers such as Mr. Enierlmc believe liut niiis: currently used insulating prod ucts dun t appear to threaten homeowners
and are less toxic than asbestos. Because* of improved plant controls, some indepen dent scientists say. any danger to current plant workers may also be low.
Nonetheless, the specter of a health crisis even vaguely resembling ihp asi bestos disaster is sparking a furor in the insulation industry. Company scientjsis are ; scrambling for evidence to defuse Mr. Enlerline s findings; some insulation pro, ducers are building defenses against future damage claims: and the safety issue is at j the hear: of a battle between producers of | competing types of insulation

Use Is Growing
Such warnings come as insulation pro ducers increase fine-fiber oulput largely for products blown under pressure into
walls and-ceilings of homes and commer cial buidings. Use of fine fibers is growing because they provide greater insulation than larger-stzed fibers, and at lower cost, says William Sells, presidem of M.uiville's glass fiber division. '
The safety deoate is putting glass fiber producers on the defensive. At a tense twohnur meefir.g last month with Mr. Enter,'mo. he i!;h officials from Mam ilie. Owens Corning Fiberglas Corp. and CertninTeed Corp. challenged the scientist s methods ano facts. They said they hope to prove j '.hit workers' deaths front lung cancer aren't related to fiber exposure, dial they
