Perlite
Filled Cavities
Conserve Energy.
Heat transmission can be reduced by 50% or more when silicone treated perlite loose fill insulation is poured into the hollow cores of concrete block or cavity type masonry walls. In fact, cavity walls of face brick and tile show a 63% reduction! But that's not all. Silicone treated perlite loose fill insulation is water repellent-indefinitely.
Specs call for a concrete block wall?
Perlite loose fill insulation can help too! By filling the core holes with perlite loose fill insulation your fire rating will be doubled to 4 hours and your "U" factor improved by 54%. And you don't have to worry about permanence. Silicone treated perlite is inorganic and rot, vermin and termite proof. And it's non-combustible with its fusion point of 2300°F.
Even a veneer wall of brick and concrete block can show a 52% improvement in insulating value when filled with loose fill perlite. Don't worry about settling - silicone treated perlite supports its own weight in the wall without settling and it's easy to handle too! Thanks to its countless glass-like cells it's light-weight and easily poured. It's quick-it's inexpensive and it's permanent-the perfect material for insulating masonry walls.

SCOPE OF DUTY TO BARGAIN
continued from page 17
that a new collective bargaining contract being negotiated include a provision, which had been in previous contracts, requiring that disputes involving new contract terms be arbitrate.
6) Products to be manufactured.
7) Requiring a strike-vote by employees before a strike is called.
8) General business practices.
9) Selection of negotiators.
10) Insistence on a contract clause outlining the union's liability in the event of a violation of a no-strike pledge.
11) Union matters-
(a) Composition of the employees' shop committee.
(b) A requirement that a contract be ratified by secret employee ballot and a clause providing that contract would become void whenever more than 50% of employees dropped the checkoff.
(c) A condition requiring that the union first organize the industry before the employer bargains.
(d) A requirement that the union give membership withdrawal cards to employees transferred out of the unit and that shop stewards be chosen from among senior employees.
12) A demand for a withdrawal of unfair labor practice charges.
13) A union's insistence upon bargaining for a unit larger than is covered by its certification.
14) Demands that the union permit the employer to use the union label or that the international union, not just the local, sign a contract.
Determining whether a particular item is a voluntary subject for bargaining is quite confusing, and it is suggested that if a question arises as to whether a subject is required to be bargained for an up-to-date legal opinion be obtained. The labor law is rapidly changing with the Labor Board continuously modifying the classification of mandatory versus voluntary subjects of bargaining. If management declines to bargain over a subject which is mandatory rather than voluntary, then the union will have grounds for filing an unfair labor practice charge with the NLRB.
