It is very prevalent in a lot of commercial buildings," Don Stefanchuk said in a recent interview, including industrial buildings, office buildings, arenas, community clubs, and hospitals. "It was the building insulation of choice back then. "To have it tested is not an expensive deal," he said. "At a maximum, it's about $500, and that's a cheap peace-of-mind investment." "A dozen times a year is a lot of times," Dave McNicholl said. "You have to remember, a lot of buildings don't have any (vermiculite insulation)."
ANSWER: While you appear to have an excellent grasp of the building-science aspects of insulation and air/vapour barrier installations in homes and crawl spaces, you have one improper statement that may be contributing to your confusion. Your false assertion is that SM insulation, or extruded polystyrene (XPS), is not an effective air/vapour barrier. This material is quite a good air/vapour barrier and is touted by the manufacturer as highly moisture-resistant. If properly sealed at the joints, it can often be installed without the need for polyethylene sheathing and offer adequate resistance to air and moisture intrusion. You may be thinking of expanded polystyrene, which is not an effective air/vapour barrier and requires use of poly for effective air and moisture control. The good ne...
Area rugs and carpets serve as sound insulators. Reshaping homes to combine big spaces, like the popular great room, have caused noise levels to go up. Rugs and carpets reduce the sound that bounces off walls and floors. Homes with hard surfaces, such as tile and wood floors where carpeting isn't used, benefit from the use of area rugs because wood floors amplify sound the most. Using a pad underneath is also a great idea. When building a home, make sure the plumber places extra insulation against pipes and traps to close up pathways for unwanted sound. An even better alternative is to fill the space with expanding foam to completely block noise pathways and stabilize pipes against any movement. Filling in around electrical junction boxes with the same foam helps keep homes warmer...
In his message to congress today, U.S. President Harry Truman proposed a new $11-billion foreign aid program to help allies bolster their economics and build armies against "grave peril" of Soviet aggression. FORTY YEARS AGO Recently, when both federal governments in Canada and the United States ordered mercury contaminated fish from the market place, officials of the Food and Drug Administration while minimizing the immediate dangers, did little to inform the North American public of the long-term effects of mercury.

MacDonnell says that recycled denim is a better thermal insulator than fibreglass with a slightly higher R-value per inch. It also acts as an effective acoustic barrier for use on interior walls. "For the project we're working on now, we're using it to insulate the mechanical room walls so the furnace and hot-water-tank noise doesn't transmit into the rest of the house. When you're putting it into the house, it's clean as far as what it's going to put into the air. As well, my crew guys don't have to protect themselves while they install it. They can wear shorts and a T-shirt. In fact, I have a sample I use in my office as a pillow if I ever get too tired." MacDonnell anticipates that the dollar gap between building green and the more conventional construction methods will continue to...

Home inspectors are trained to view houses as one large system, composed of many smaller, interconnected systems. A change in one or more of these smaller systems, whether they are structural, mechanical, or otherwise, will affect the overall performance of the house. In regard to your leakage and moisture issues, the energy efficiency upgrades completed have affected the exterior shell of the house, or building envelope. The reasoning behind this may be obvious with the new windows, which are much tighter than the old ones in reducing air leakage, but less so with the insulation and furnace. The added attic insulation also reduces air leakage through the top of the building envelope, into the attic. The least obvious of the three, in terms of reducing air loss, is the furnace. Newer hi...
Cutting open the exterior wall in your cottage to install the door has compromised the air barrier and possibly the vapour barrier, which is the likely cause of your problem. This was done by cutting through the exterior wall sheathing and building paper or Tyvek on the outside and the interior wall sheathing and poly air-vapour barrier, if present. To elaborate on this, we must explore the details involved in construction of a typical insulated exterior wall of a home. If we cut a cross-section through the exterior wall in your cottage, as was done to install the new door, we should find this typical form of construction, looking from the outside in: siding, building paper, exterior sheathing, fibreglass insulation between wood studs, polyethylene air-vapour barrier, interior panelling...
In June 2008, Pollock's Hardware was reborn due in a large part to the historic cooperative values that were embraced by our North End neighbourhood. Little did we know at the time that we would be starting up this unique community enterprise amidst one of the worst economic recessions of our times. On the first year anniversary of the re-opening of the store, which had closed after 85 years when the owners retired and a new owner could not be found, we are pleased to report that while global capitalism is unravelling, Pollock's Hardware Co-op is making record sales. No bailouts required here. Our community-owned hardware store on north Main Street is thriving. Another major feature of the co-operative approach adopted by Pollock's is to support local community enterprises through our s...

The water was at least five inches deep everywhere, and a foot or more in some places," said Ross Rumberg, owner of Rumor's Restaurant and Comedy Club. "Every wall in the building was touched -- all the drywall and insulation had to be ripped out, all the electrical had to be replaced, several pieces of technology were fried. It was really devastating. Rumberg said the club's loyal following might not notice many physical changes to the showroom, but there have been significant improvements to Rumor's' menu, food-service procedure and the thematic flow of each night's dinner-to-showtime transition.
[Sam Katz]'s green plan calls for new city buildings to meet international energy-efficiency standards. He also promised incentives for building owners to install "green rooftops" -- vegetation that acts as insulation and reduces the amount of water flowing into city sewers, while sucking up carbon dioxide. It's nice to see Sam Katz jump on the green bandwagon, but after two-and-a-half years of inaction, I'm skeptical," [Hasselriis] said. "I can't believe he actually used the word 'sustainable.'
