Level to Obtain Higher Priority Rankings
Right now, public agencies tend to under-rate the importance of our product and, as a result, assign to brick producers relatively low priority rankings for energy consumption. Thus when it becomes necessary to reduce energy consumption as it already has in many areas brick producers are among the first to suffer. We are trying to change this situation. There are other things that can and should be done and all of them will be done faster and better if they have the active support of the entire masonry industry.
Brick producers believe that the masonry industry is inter-dependent to an unusual degree. A problem in one area-such as a shortage of labor, or brick, or gas-affects all areas of the industry.
If we act on a belief in our inter-dependence, we not only can solve present problems, but also we can grow and prosper together.
Massachusetts Bricklaying Contest
Paul Prunier of Worcester, an apprentice representing Local No. 6 of Worcester, was the first place winner in the 24th annual apprentice bricklaying contest sponsored by the Massachusetts State Conference of the BM & PIU in Framingham, June 2. Presenting the award is Jack Kratz, president of the Mason Contractors Association of Massachusetts. Thomas F. Murphy, president of the international union, and Charles Velardo, MCAA vice president, are shown greeting the apprentices and interested spectators.
Twenty-two apprentices from locals throughout the Commonwealth competed in the four-hour program judged on accomplishment, skill and aesthetic values. A cooperating sponsor of the event was the Massachusetts Masonry Institute, Boston.
The Perlite Way to Fill a Cavity
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.
