Benefits of Metal Building Insulation

Our metal building insulation helps with:

  • Condensation Control: Condensation occurs in steel buildings when warmer moist air comes in contact with cold surfaces such as framing members, windows and other accessories, or the colder region within the insulation envelope (if moisture has penetrated the vapor retarder). A good facing with a low perm rating is critical in controlling moisture migration in the building envelope, which is why we use Lamtec vapor retarders in our lamination process.
  • Attractive Installed Appearance: Our extensive vapor retarder product offerings ensure an attractive finished interior appearance in metal building roofs and walls.
  • Cost Savings: Our insulation products help control the indoor temperature, leading to energy efficiency and cost savings for building owners’ energy bills.
  • Sound Abatement: Metal building insulation reduces noise transfer from inside and outside of the building, providing superior noise control.
