DANBURY -- Danbury High School will get all new windows in its original building this summer as part of the city's energy efficiency plan for the facility.
The school's boilers were replaced last summer.
The school will be closed for the summer, and city officials are reviewing whether the whole Clapboard Ridge campus should be off limits during the work.
All the windows in the main building, which was built in 1965, will be replaced. That excludes the A and D wing and the new science wing.
"The caulking is hazardous matter and requires remediation," the city's construction manager, Dan Reisert, said Tuesday.
"The absolute rule is that no one under 18 can be in the building or within 75 feet of any work taking place, and that is close to the fields and tennis court."
He said there are a lot of windows to take out and replace, and several crews will be working simultaneously so they can be finished in eight weeks, before the start of the next school year.
"There will be trucks and equipment and lifts," he said. "It's a very intense job to have every window replaced in eight weeks."
Joe Martino, Danbury schools assistant finance director, said the city is running the project but district administrators would like the school grounds to remain open to the public.
"It's still being discussed," Reisert said, about summer use of the site.
The city has scheduled a meeting about the project for Thursday.
