After, steel posts and wall girts cleaned and painted. Then new metal building insulation was installed, increased R-value, new look.  Clean!  Houston, TX

Interior insulation retrofit

In the two pictures below you will see an interior insulation retrofit. In cases where more that 4" of insulation is required this can be accomplished from the inside of the building.  In this case the old insulation was cut-out.  Nylon banding was installed to hold the insulation in place and 8" of new insulation with new white vinyl facing was installed.

This picture is before the insulation was cut out.

View from inside the building, insulation change-out / replacement, side by side. The new insulation is so bright its hard to capture a good picture.

The two photos above are from the same project.  We picked up the roof panels, replaced the insulation, then re-installed the insulation.  New insulation is so bright and reflective it makes taking a photo quite a challenge. Lapeer, MI  August 2016.

Metal building insulation renovation replacement.  

The metal building insulation can be replaced either by removing the outside wall panels or from the interior.  If, due to the configuration of interior elements, the insulation is difficult to access the exterior approach may be necessary.  We have completed many retro insulation projects.  

If insulation is added by peeling back the panels and installing the insulation you will achieve the same look as if had been completed during original construction. 

There are many facing options available.  Based on your needs you can select a facing strong enough to withstand a hockey puck, a soccer ball, to a basic reinforced facing.  There are also different color options, but the options are  limited.  The R-value you are able to achieve is based on your needs.  

While changing your insulation this is a great time to paint your frame.

 

How will adding insulation to a metal building affect the internal temperature?

For the past 20 years, we have looked for some independent company to provide us with data on this subject.  A utility, federal or state tests, a building manufacturer or insulation company.  The best we have come up is 10 to 15 degrees.  That is the number our insulation manufacturer provides us with.  Thats based on a 3" thickness.

It is typically one of the first questions we are asked when someone is interested in renovating a building to add insulation, what will be the affect be?  The problem we have encountered is there doesn't seem to be any broad or specific independent information.  We have contacted utilities, and metal building manufacturers.  They all say you will see a temperature drop in the summer, and a more comfortable environment in the winter, without any specifics.  What the insulation does is create a radiant heat barrier keeping the hot air out of the building by not allowing the heat to radiate in.  During the heat of the summer the surface of the roof panels can get as hot as 140 degrees.  Leather gloves and thick soles in boots are required to work on roofs during the heat of the summer.  By keeping out the radiant heat, the internal heat from the building has more space to occupy in the roof. 

Roof vents and turbines are also helpful.  These devices can provide information about how fast the air in a building can be exhausted.  Their benefit is they are quiet, and free.

The feedback we get varies because of the physical differences of the buildings, also many buildings have A/C installed as part of the renovation process.   The other factors that affect the results are the height of the building, the ground level ventilation, if the walls are insulated.

Based on our experiences, and the feedback from our insulation company, expect a drop in temperature of 10 to 15 degrees during a hot summer day.  I know the workers in a newly insulated building always appreciate the environment after we have completed a insulation renovation.

Another benefit is to minimize the effect of electrolysis that is occurring between the roof panels and the purlins by installing the insulation between them.
