AAP / McCUSKER-GILL GIVE CASWELL FIRESAFE® MASTERCLASS
For those who have not yet heard of this coup for our U.S. Licensed Manufacturing Partners Atlantic Air Products Mfg LLC and McCusker-Gill, along with Firesafe and the CASWELL FIRESAFE® brand…

AAP / McCusker-Gill secured this remarkable office & laboratories project – known as 74M – in the heart of the Middlesex bio-tech district in Boston, Massachusetts for CASWELL FIRESAFE® Fire Resisting Ductwork.
McCusker-Gill is the leading HVAC Sheet Metal Contractor in Boston and their President Kevin Gill Jr. was recently named SMACNA 2023 Contractor of the Year and commended for his drive to promote technological innovation. As you can imagine this is a huge honour in the USA and it is gaining a lot of media attention.
Their President, Kevin Gill Jnr – had some great things to say about CASWELL FIRESAFE® and the response from the industry both in the States and the UK has been terrific, as these samples from LinkedIn testify.
• Caswell offers a best-in-class fire-rated duct option…
• This Caswell Firesafe Fire Rated ductwork install in the penthouse of our project on Middlesex St. is a thing of beauty!
• This is the best fire-rated ductwork product in the marketplace (we’ve installed them all, and it’s not even close!)
• That is a work of art and should be in an art gallery

• Looks superb. Don’t put the ceiling in
