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 insulatlon 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.

Portland's O'Bryant Square Honored
The U.S. Department of Housing & Urban Development (HUD) has awarded O'Bryant Square and the Fountain for a Rose in Portland, Ore., an Honor Award for design excellence as part of the agency's national recognition of improvements to the urban environment. Accepting the award in ceremonies on November 10, 1976 were city official Robert Gordon and Donald W. Edmundson and R. Evan Kennedy of the Portland office of Daniel, Mann, Johnson & Mendenhall, who designed the park. The half-acre, landscaped oasis in downtown Portland is the focal point for the city's annual Rose Festival ceremonies and is in daily use as a popular meeting and pedestrian area.

The average family in 1953 had an income of $5,000 and paid 11.8% of family income in direct Federal, state and local taxes. By 1975, the average family had an income of $14,000 and paid 22.7% in taxes an increase of 92.4% in the portion of income going for taxes. In other words, taxes take twice as much of a family's income. The Chamber of Commerce of the United States says the net effect of these increased taxes has been to lower the standard of living because the government leaves taxpayers with less of their own money to take home and spend as they wish.
