I have been in the field of structural passive fire protection /air sealing and the thermal Insulation industry since the early 70s, far longer than most companies have existed. Since it’s a relatively new field to be added to the construction industry since the mid 90′s we hold a great deal of knowledge in all matters appertaining to the above trades.Should you wish to know more of my extensive history within the industry you can listen on "Fire & Smoke Control: Our Background" at https://fireandsmokecontrol.buzzsprout.com/1591372/8347079 or simply ask!
