In New York City, Mark Z. Jacobson, a professor of civil and environmental engineering at Stanford University, has been doing a study on white rooftops for apartment buildings to see if the color change from black would have any kind of affect on keeping the buildings cooler and more efficient. Their findings have been very eye opening. So much that the city is embarking on a push to change as many roof tops as possible to white. The change could have enough of an effect on the downtown area, that it would actually reduce the “heat island effect” that makes the city 5-7 degrees warmer than the actual temperature at night in the summer. In 2011, on the hottest day of the summer, a white rooftop measured 43 degrees cooler than a black roof. That is huge and no doubt will reduce energy consumption for the building.
Branson was just one of many areas hit by devastating storms just yesterday. The tourist town of Branson was hit by a tornado with winds of up to 130 mph that was reportedly 400 yards wide and on the ground for 22 miles. Miraculously there were no fatalities and only 33 injuries from the storm that hit around 1:00 a.m. March 1st. The town and its businesses are working feverishly to get things up and running if possible, by March 12th, which is the beginning of spring break for the area. There will be some businesses that will have no chance of opening anywhere near that date, as they sustained heavy damage and will need months to make repairs or rebuild.
You hear it all the time when window shopping. The windows you are looking at will typically say that they are “gas filled” windows to conserve energy and increase thermal value. So what kind of gas do they use anyway in these windows? Is it dangerous? Here are the facts for you to be a consumer in the know.
There are two common types of gas that are used in windows. Argon and Krypton. Both gases are called inert gases, meaning they do not react readily with other substances. These gases have a higher resistance to heat flow, then air. The gases are sealed between the panes to decrease a windows U-Factor, or the rate at which the window conducts non-solar heat flow. Argon gas is inexpensive, non toxic, non reactive and odorless. Krypton is more expensive and has better thermal performance.
There you have it. A crash course on window gases!
Designed by Franklin Long & Frederick Kees, and built in 1885, the Lumber Exchange building was billed as one of the country’s first “fireproof” buildings . It is the oldest high rise building in Minneapolis and outside of New York City is the oldest building with twelve or more floors. The building you see now was built in three different stages. The original building was tall and narrow, later a wing was added and later still 2 stories were added to the top. Some call it ugly and others realize that it is a significant part of architectural history, and for that, it is beautiful in its own right.
When insulating your attic you will need to choose from Batt or roll insulation, and loose fill insulation. So what are the differences between the two? We thought we would spell it out for you so you have a general knowledge of the differences. Contact us to talk about your situation.
Batt or Roll Insulation – The more common type of insulation that comes in the form of a roll that consists of flexible fibers, usually fiberglass. You also can find rolls made from minerals, wool, plastic and natural fibers, such as cotton or sheep’s wool.
Rolls are available in widths of standard spacing of wall studs, and attic or floor joists.They are available with or without facings. Manufacturers often attach a facing to act as a vapor or air barrier. Rolls with special flame-resistant facing are available where the insulation will be left exposed. A facing also helps with fastening during installation. However, it’s recommended that you use unfaced rolls if you’re reinsulating over existing insulation.
Loose Fill Insulation – Loose-fill insulation consists of small particles of fiber, foam, or other material. These particles form an insulation material that conforms to any size or type of space. The ability to conform makes loose-fill insulation well suited for retrofits and for situations where it’s difficult to install other types of insulation.
Most material used for loose-fill insulation include cellulose, fiberglass, and mineral wool. These materials are made using recycled materials. Cellulose is primarily made from recycled newsprint. Most fiberglass contains 20%–30% recycled glass. Mineral wool is usually produced from 75% post-industrial recycled content.
Last year demonstrated how closed loop recycling can and does work in the real world. GM removed and replaced 475,000 square feet of roof at its Customer Care and Aftersale building in Lansing Michigan. Approximately 1,000,000 feet of recycled roof membrane was replaced and all the old roofing was shipped off to be recycled into roofing material once again and in the end, diverted about 120 tons of material away from landfills. The new roof is white and reflects the suns rays, thus reducing the heat flow and saving on Air Conditioning costs. GM currently has 74 plants that do not send any waste to landfills.
Did you know that you can own a piece of the teflon that was the Metrodome roof, before it collapsed in 2010? Yes, believe it or not people are paying about $10 and up for a piece of the roof that collapsed in that December snow storm of 2010. There are a few different variations that you can get too. Such as a Joe Mauer plaque with his #7 cut out of the roof teflon, mounted next to his baseball card on wood backing. How about a Authentic Teflon printed Vikings football with purple printing on it, or a 1987 “Domer Hanky” cut out of the teflon roof? In all there looks to be about 27 different pieces that you can pick up in all price ranges. Hmmm, maybe for a good gag, you should send a piece of the roof over to that buddy of yours who can’t stand the dome. LOL!
When hiring a roofing contractor, you will want to make sure that whoever you are hiring knows the codes for your city, and abides by them, before replacing your roof. Getting in trouble with the city inspector is the last thing that you want to have happen. Here are some of the codes that your contractor should know.
- How they need to deal with existing roof layers.
- Underlayment codes
- Flashing requirements
- Type and length of fasteners to use for code.
- Attic ventilation
- Permits & Inspections required
Hiring a well qualified roofing contractor will save you headaches down the road.
Two rookie roofers are up roofing a home. The first rookie pulls out a nail and then hammers it into the roof. Then he pulls out another nail, looks at it, then throws it over his shoulder. Rookie #2 eventually saw what Rookie #1 was doing, watched him a while and then said, “Why do you keep throwing out every other nail?” Rookie #1 replied, “Because their points are on the wrong end.” Rookie #2 then said, “You airhead, those nails are for the other side of the roof!”
