A building depends on its boilers to keep the residents comfortable in the winter months. Unfortunately, the boiler room was not designed properly to deal with the heat generated by the boilers.
The boilers would get the mechanical room so hot that it would trigger a safety switch and shut off the boilers. The heating contractor had to come several times to bring the system back up at considerable expense. The owner wanted to replace the old insulation with a higher efficiency type while keeping the room cool and avoiding having the safety protocols tripping the boilers.
The old insulation surrounding the boilers was removed and closed cell spray foam insulation was applied. The challenge was getting in the tight areas to apply the spray foam. Some of the sensitive mechanical equipment needed to be protected from overspray and job coordination with the HVAC contractor was required. In the end, the boilers became more energy efficient and the room became a more comfortable space in which to work.
“In the beginning I was ready to replace the old insulation with new insulation from a reputable supplier. The new foam insulation was cheaper in the end and was much more energy efficient. The boiler room now only gets to about 70 degrees in the winter months where it used to get up to 120 degrees! I am impressed of the insulating benefits of closed cell spray foam insulation.”
