Duct Insulation

On Time Insulation is a specialist external duct insulation installer for HVAC systems. Our experienced staff have managed to supply and install of glasswool duct insulation of over 21,500m² on a single project. 

Quality is at the heart of what we do and is critically important when installing thermal duct insulation. Products include glasswool blanket, polyethylene sheet, and polyester blanket installed professionally, either pinned or banded into place. 

We can retro-fit internal duct insulation into place in new ducts or repair existing.  Non-fibrous solutions for ‘clean’ applications such as pharmaceutical manufacturing and operating theatres areas are all available. 

We are an installer of Trafalgar Fyrewrap duct insulation systems. Please see passive fire protection or contact us for more information.
