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.

"The adjacent shopping area was articulated in the same spirit, and its structures were accomplished in the same materials to provide a background for the Bay View building as well as a group of structures acting in unison. These include a variety of stores Walgreen, Pic-A-Dilly Dress Shop, Sweet Tooth Candy Shoppe, Radio Shack, and others.
A "flying" roof design, inclined walls and arches express themselves gently, gracefully and effectively in the Bay View Federal Savings Building configuration. Earth-toned, tan brick lend a feeling of warmth and hospitality to the structure.
A large and easily accessible parking area fronts all the stores in the center." The dry-press giant brick used for the Bay View building are actually "thru-the-wall" or brick-block units, 8" x 4" x 16" in size. They were specifically selected by the architect for color, color permanence and waterproof qualities. The structural walls are completely grouted and reinforced. The mortar used is a natural color. The roof is constructed of flat concrete tile units, 4" x 4" x 16".
Construction was completed at a fast rate with a recorded June, 1973 starting date. Completion was accomplished for a November 15th opening. Arcihtect Al-Yassin credits much of this to the mason contractor, Milo Masonry. "They were easy to work with, and even more important, they worked on the building with a genuine sense of accomplishment," the architect commented.
The MCAA Workmen's Compensation and General Insurance Plan offers a positive approach to loss control. To help keep premium costs low and dividends high, CNA's national loss control and industrial hygiene services are available from more than 150 loss prevention engineers to all MCAA members who join the program.
Members of a hunting party were asked to bring only male hounds. One member, however, was down to his last hound, a female, and out of courtesy was permitted to include her. The pack was off in a flash. In seconds they were completely out of sight. The confused hunters stopped to question a farmer in a nearby field. "Did you see any hounds go by here?" "Yep," he said. "And it was the first time I ever saw a fox runnin' fifth!"
