Safety First – Man Killed by Falling Tape Measure

Posted on by

A New Jersey man delivering sheet rock to a construction site was killed Monday when a tape measure fell fifty stories and hit him on the head.

The 1-pound tape measure became dislodged from the belt of a worker on the 50th floor and struck construction equipment about 10 to 15 feet from the ground. It then ricocheted and struck a 58 year old man in the head. The man was not wearing his hard hat at the time, and unfortunately lost his life shortly after the accident occurred.

Being on a construction site can be extremely dangerous, and you never know when some freak accident can occur and potentially cause severe damage or even result in death. Please take extra precautions next time you are working on or even near a construction site.

Wet Materials

Wet material should be removed from a job site. You never want to use wet material when working with a roofing system. Wet materials in roofing systems can seriously affect its performance. Wet materials can also promote the growth of mold.

When insulation gets wet it even loses its R-value. Wet insulation should never be used. Some components like metal can be dried out without causing permanent damage to the material. Just make sure the metal are not rusted or corroded before installing them.

 

Roof Break-ins and Protection

Posted on by

I’ve been reading more and more about people breaking into buildings through the roof. Which I’m sure a lot of business owners are more concerned about the damage done to the roof, than the actual items they stole or at least attempted to steal.

I just read about police arresting two teenagers after the roof of a mall was cut in an apparent failed attempt to steal some sneakers. Investigators say two teens were captured at the scene. A third youth escaped while trying to flee via the roof. More than a dozen pairs of shoes were abandoned atop the roof.

The teens are facing burglary and evading arrest charges. The mall was forced to close down early that day, and now will have to fix the roof. These little burglaries are costing companies a lot of headaches and money.

Some Companies have bulked up Security

Some companies have taking it to the extreme to prevent these types of roof break-ins. A Miami business has chosen to house a dog on the roof of their building for property security.

 The company claimed that they have been burglarized three times and the presence of dogs seems to be the only way to keep thieves at bay. Animal activist are burning up about the dog living in these types of conditions. Which is very understanding, anyone that has been on top of a roof during the hot summer months would understand. I’m not writing this to decide who is right or wrong, personally I just think it is a very interesting story.

Types of Roof Insulation

Posted on by

The most common or found in low-slope membrane roof systems in North America:

RIGID ROOF INSULATION

Cellular glass

Expanded Polystyrene (EPS)

Extruded Polystyrene (XPS)

Fibrous glass

Gypsum board

Mineral fiber

Perlite board

Polyiso

Wood fiberboard

Composite board

 Reduce Thermal Bridging

Mechanically fastners are good conduits for thermal bridging. With two or more layers of insulation, the potential for thermal bridging at fastners in the first layer is mitigated.

 Reduce Thermal Loss

A minimum of two layers reduces the thermal loss that occurs through the joints between single layer insulation boards.

Increase Thermal Performance

With double layer insulation roof systems, it is preferable that only the bottom layer of insulation be mechanically fastened that are appropriate for mechanical attachment.
