Steel buildings use steel for the support structure as well as for exterior cladding. Steel construction has numerous benefits over buildings erected using other materials, but metal being a very good heat conductor and a material that is sensitive to corrosion, it is essential to use properly calculated, well-chosen and professionally installed insulation to be able to benefit from the desired energy-efficiency, functionality and comfort during the usage of your steel buildings. For ease of construction, look to a manufacturer that offers steel building kits ready to order.
The insulation plays a double role in any type of building: it stabilizes the interior temperature and it prevents the penetration of moisture. Here is how to choose your insulation material:
Technical Parameters to Look for When Choosing the Insulation Material
Insulation materials come with performance information and ratings – the R-value indicates thermal resistance, the U-value indicates thermal performance and permeance indicates the performance of the material when it comes allowing moisture to flow through. What you need is high R and U values and low permeance,
Insulation Type
There are many different types of insulation used in steel buildings, here are the most popular ones:
- loose fill that is blown into the space between the steel sheets provides superior insulation, but is quite expensive.
- blankets made from rock wool or mineral fibers.
- spray foam – applied in the form of liquid into the walls.
- fiberglass – another type that comes in the form of blankets. It is efficient and inexpensive.
- insulated panels – the most expensive type, but very quick and easy to install and very efficient, too.
