With metal buildings, insulation does two main things.
It stabilizes the structure's interior temperature, and prevents moisture from entering or collecting via condensation.
It is critical to insulate your metal building, because metal is a much better heat conductor than wood.
If you don't insulate your metal building, it won't be able to retain heat in the winter, and the summer months will be unbearably hot.
When the temperatures vary a lot from inside to outside, condensation forms.
That moisture will allow unhealthy mildew and mold to grow, and that will be particularly harmful to people with allergies.
WIthout proper building maintenance practices, the moisture will also cause rust and erosion, the last thing you want in your metal building.
In traditional timber buildings, insulation is installed between the stud.
In metal buildings, insulation is typically installed over the framing to provide continuous coverage.
That prevents any transfer of energy and/or moisture between the framing and the exterior roof and wall panels.
There are several different types of insulation used for metal buildings.
The costs and benefits will vary between them, so it's important to do your research before deciding what the best option is for your metal building.
In the article below we will discuss the different types of insulation available and how they work.
