Regulate, Moderate, Insulate – Safeguard Your Metal Building with Proper Insulation

Almost everyone knows that insulation moderates interior temperatures in a steel building. It keeps warm air inside during cold winter months and prevents heat from penetrating your structure in the summer. But for a steel building, it’s even more important. Insulation creates a barrier in the roof system and walls that prevents condensation – more than an annoyance, condensation can compromise the look, lifespan, and stability of your steel building.

In many areas, local building codes require that your steel building be insulated. Buildings without heat or air conditioning can usually pass inspections without insulation, but for just about every other kind of steel building, some kind of insulation is going to be required.

Choosing the right kind of insulation is important – several factors are involved:

  • Your region’s climate
  • Your skill at application of the insulation
  • The use of the building
  • Of course, budget!

The experienced team at Great Western can help you make the right insulation choice.
