How To Insulate An Existing Steel Building. I am located in wisconsin. Building was constructed with soffit and ridge vent.
The result will be a building that stays cooler in warmer months and warmer once the temperature drops. If you can open up some vent holes (covered in weldwire) at the bottom on the north (or less optimally east) side of the building and along the top (even better would be a cupola) you can take advantage of the stack effect to move the hot air up and out and replace it with slightly less hot air. Fiberglass is also one of the preferred materials for metal and steel buildings and homes.
How condensation is created condensation is created when warm air from inside your steel building comes into contact with a cold surface such as your roof or wall panels.
Building was constructed with soffit and ridge vent. Steel panels alone offer no protection from the outside temperature, meaning there is no natural barrier to heat and cold. *illustrations below interchangeable show options where the foil is facing in the building and where the white is facing in the building.
