Spray polyurethane foam has been proven to be the most efficient insulation system for both residential and commercial metal buildings. Spray foam insulation provides a continuous, uninterrupted thermal break that dramatically reduces and eliminates air leakage. Spray foam also prevents radiant heat from the sun from transmitting into the interior air space of your metal building, making even a non-air conditioned space much more comfortable during the summer months. In the winter, the space can be heated much more efficiently without the hassle of condensation drip, which often occurs with metal buildings. It is a long-lasting improvement that anyone can have added to their metal garage or work space.
