Solar Panel Cause of Fire at Webster Groves High School

No comments

WEBSTER GROVES • Firefighters quickly extinguished a fire Saturday on the roof of Webster Groves High School, officials said.

The fire broke out about 1:45 p.m. The cause has not yet been determined, but Webster Groves Battalion Chief Tom Yohe said it was “possible” the fire was sparked by one of the school’s solar panels.

Departments from around the area responded to the 2nd alarm call. The fire was contained within 15 minutes, Yohe said.

Officials said there may be some water damage to the school’s third-floor classrooms from fighting the fire. No firefighters were hurt, and any damage to the building was minor.

The school’s seniors graduated Friday, but Yohe said because access to the roof was difficult he “seriously doubted” the fire could have been started by students.  The school is expected to be open Monday.

Structural Insulating Sheathing

2 comments

Combines insulative and water-resistant barrier benefits with structural properties to offer an affordable method of bridging the thermal short-circuiting of a building’s frame. 

Exterior walls must provide multiple functions including  weather and air resistance, energy efficiency, and structure. Most commonly,  these functions are met with a combination of materials that are typically  individually installed.Structural insulating sheathing provides a  multi-function exterior wall sheathing product that is applied in a single  layer and provides additional continuous insulation, a weather- and air  infiltration-resistant barrier, and structural wall bracing. The product is a  marriage of two proven sheathing materials—foam sheathing (polyisocyanurate)  and structural laminated  fibrous board with a thermal resistance of R-3 for ½-inch thickness.

Structural insulating sheathing provides a structural method  of design for braced wall panel construction, and many additional benefits.  Using a single product simplifies wall construction and allows labor savings.  It can be installed using common construction tools and skills, and time is  saved since it eliminates the installation of a separate layer of building wrap  or felt paper for the weather-resistant barrier (WRB). Further, it reduces  handling and improves worker safety by replacing two installations with one of  a lighter panel weight.

Beginning  in 2006, the International Residential Code (IRC) will require a WRB over OSB  for code compliance when using most of the conventional exterior cladding  systems.

A special thanks to my good friend Paul Hasenmeier  from First Due Tackle for sending me these pictures of an apartment that was going up in his area to motive me to compile all the information I already had on Structural Insulating Sheathing and take it from my Green Building Construction Class and put it into a written post where all could read and share.

The only way to know this kind of energy efficient  construction is being built in your area is to get off the couch and go walk through these buildings as they are being built!
