7 Cooling Tips for Metal Buildings in Summer Heat

Greenville is a hot place in the summer. It is important to consider the extreme heat when designing your metal building. This will drastically affect the building's interior temperature. The energy bill you will be paying as your HVAC system works harder, longer, and maintains temperatures at the desired level.

There are many things you can do to cool your metal building. We will discuss each method and its effectiveness in cooling your building. These tips will make you feel comfortable while improving your energy efficiency and the air quality.

Let's start by looking at some science concepts to understand how buildings can get so hot in the summer.


It is hot outside so buildings lose lots of air. Summer is hot and cooler. In addition, even though your building is losing cool, hot air will enter your home to replace the lost air. This is thermodynamics. This is thermodynamics in action. Heat seeks equilibrium continuously; heat moves towards cold until everything is at the same temperature.

Heat is persistent in finding a way to enter colder areas until there is neutralization. Listed below are the three main ways heat "moves" into your colder home:

Conduction Heat conducts heat from one side to the other. Direct contact results in heat transfer. Also, heat from your hot roof is transferred to your hot attic.

Convection When hot air rises and causes your attic to get hotter than the rest.

Radiation. When the scorching sun heats your roof or walls

Interiors can become uncomfortable when too much heat flows towards the cooler area.


Insulation doesn't just keep your building warm in winter. Insulation is also an effective way to cool older buildings. Insulation acts as a barrier to keep the outside heat from entering your home.

Insulating your home can reduce your cooling and heating costs by adding insulation. Attic space accounts for the majority of heat loss and heat gain. Attic insulation is therefore a must-have.

Talking to an expert is important because buildings have different insulation requirements depending on climate, building type, and usage. You should look for insulation that comes with a warranty of between 6 and 10 years. After the expiration of the insulation's warranty, it is important to replace or renovate insulation.

Home sealing

Consider your ideal temperature-resistant building like a thermostat. Your building should be sealed because thermostats are well-sealed. You should make your building seal-proof to prevent hot air from getting in. This greatly increases your building's energy efficiency and means your cooling system doesn't have as much to do.

Lucky for us, metal is not as porous as other types of building material, so it forms a tight seal that helps to mitigate energy loss.

Get Hot on Your Roof

Your roof is the most visible part of your house. Your roof not only absorbs the sun's rays but also collects internal heat air. Hot air rises. Roofs made of certain roofing materials can heat up as high as 200 F. You will still need to use energy to cool your metal building in Kinston NC if your roof is not properly maintained.

Modern metal roofs are efficient at reflecting heat and can help reduce cooling costs up to 25%. Metal roofs are much cooler than asphalt, wood tile, concrete shingles, and tile. Metal roofs with reflective coatings, which are lighter in color, can reflect more of the sun's UV radiations back into your building.

Roof mist cooling, also known as evaporation, is a cool and innovative way to lower the sun's impact on your roof. You get the benefits of cool roofs at a lower price, and your roof will last longer. The misting system sprays ultrafine mist onto your roofing. The sun's energy evaporates this mist. Cool air is created by the vaporized droplets of water. The cool air is then absorbed onto the roof and the hot air rises. This system is used primarily for commercial roofing but is slowly becoming part of residential use.
