There’s a good reason why spray foam insulation (SPF) is one of the most commonly-used insulating materials in the US today. As a spray-on liquid, it is easy to control and apply, especially on tiny, hard-to-reach corners. It is lightweight, which means an SPF-insulated roof doesn’t put additional strain on a commercial building’s foundations. It also helps make them more energy efficient.
A & L Foam Insulation, Inc. has been using spray foam insulation as our choice material for our roof insulation services for more than two decades. Hence, we can attest to its effectiveness, not just at keeping indoor temperatures comfortable but also in helping commercial buildings conserve energy.
SPF foam spreads and solidifies immediately after spraying. In the hands of an experienced SPF contractor, the spray foam insulation will form a continuous barrier with no gaps or spaces. The seamless insulation functions in two ways:
Air Sealing Barrier
Air leaks from entrances and exits are one of the culprits of energy inefficiency in commercial buildings, especially in malls and establishments with high foot traffic. Additionally, roof intersections, crawlspaces, and ventilation ducts allow air to pass in and out of the building. These leaks, along with other factors (i.e., cavernous spaces, a high volume of people present at any given time, etc.), cause central heating and air conditioning systems to consume more energy to reach the ideal indoor temperature during winter and summer.
As SPF leaves no cracks uncovered, it is an effective air sealing barrier for commercial buildings.
Heat Transfer Resistance
SPF has an R-value of 6 for its closed-cell variant. This is a high score that indicates its effectiveness at resisting heat transfer. In other words, SPF is an effective barrier against the heat of the sun in summer. It also functions inversely in winter: It prevents indoor-generated heat from escaping through the roof.
To sum it up: spray foam maintains the temperatures established through the central AC or heater. This attribute makes it a great indoor temperature regulator for commercial buildings regardless of the season.
Ideal Insulation for Metal Roofs
Spray foam insulation works for most types of roofs and structures. It is especially effective for metal roof systems, which are susceptible to damage when moisture pools due to condensation.
Condensation forms when the air that’s warmed by the day rises and comes in contact with the roof, which is cooler at night. If this happens frequently, the resulting moisture can lead to rusting and mold growth. Insulating metal roofs with SPF prevents this. The layer of foam serves as a barrier that prevents condensation from pooling into the roof system.
Bear in mind, too, that metal is a conductor of heat. In summer, warehouses with metal roofs can be as hot as a furnace without proper insulation. SPF, with its high R-value, can block out outdoor heat. The air conditioning system won’t have to work double time to maintain a comfortable temperature inside. Electricity consumption could go down, which should be good for business.
With SPF aiding HVAC systems in regulating indoor temperature, commercial structures get to save more on electricity and utility maintenance bills.
The National Institute of Standards and Technology (NIST) estimates that sealing air leaks generates savings on gas and electricity. Retail buildings can save up to 98 percent and 18 percent on gas and electricity, respectively; office buildings can save up to 77 percent and 33 percent, respectively. Whole Building Web Design Guild, a program of the National Institute of Building Sciences, says it’s possible to cut energy costs in commercial buildings by 40-70% through high-performance HVAC systems and building features that help improve indoor environmental quality.
