Lightweight Melamine Foam Pipe Insulation

Our lightest pipe insulation, it's often used on overhead pipe or long runs to avoid overloading supports.

Slit Tubes

Ready to fit over straight pipe sections. Just pull open the insulation, snap it around your pipe, and seal it closed with the adhesive strip.

Sealants—Close gaps, seams, joints, and punctures in your insulation.

Insulation Tapes—Wrap around pipe insulation for a tighter seal.

Clean Room Lightweight Melamine Foam Pipe Insulation

Limit contaminants in clean rooms and sanitary environments. The jacket on this insulation meets ISO Class 5 and Fed. Spec. Class 100 clean room standards, so it won’t shed particles. It’s also washable, making this insulation good for stainless steel process piping and clean steam distribution systems that undergo frequent cleaning. In addition, the lightweight melamine won’t overload supports on overhead piping and long runs.

Slit Tubes

Ready to fit over straight pipe sections. Just pull open the insulation, snap it around your pipe, and seal it closed with the adhesive strip.

Sealants—Close gaps, seams, joints, and punctures in your insulation.

Insulation Tapes—Wrap around pipe insulation for a tighter seal.
