Benefits of an Insulated Commercial Garage Door
Insulated commercial garage doors help protect your facility, your products and your employees from extreme temperatures (unfortunately single-digit temperatures with below zero wind chills are commonplace in January).

When an insulated commercial garage door is closed, it helps keep temperatures comfortable inside your building. So even when the door is open, temperatures won’t fluctuate as bad as they would with a non-insulated door. Without insulation, the temperature inside your building won’t be able to recover as quickly when the garage door is open. Plus, a non-insulated door just can’t offer the same type of protection from the elements that an insulated one can.

Insulated commercial garage doors are also quieter. Many insulated commercial garage doors are built by sandwiching a polyurethane core between steel. These doors are tightly constructed to minimize gaps, which also reduces vibration and noise. If your employees are working by a commercial garage door, the quieter the noise, the better the work environment.

These benefits come from the increased R-Value of an insulated commercial garage door.

What’s R-Value?

R-value is a term typically used in the construction industry to rate the “effectiveness of insulation in stopping heat flow opposite of conductance.” The higher the R-value the greater the insulating properties of the commercial garage door.

Keep in mind, the R-value can fluctuate based on the methods of manufacturing, like the materials used. For example, one manufacturer may rate a commercial garage door at R-18, and another might rate a similar door at R-20. Both doors might offer the same level of insulation, but the R-factor differs due to how the door is made.

Varieties of Insulated Commercial Garage Doors

Overhead Door’s Thermacore commercial garage doors are designed with thermal breaks between internal and external skins, PVC thermal breaks and joint seals minimize air infiltration and provide one of the highest thermal efficiency ratings in the industry for specified applications.

Thermacore® Wind Load Insulated Sectional Steel Doors are engineered to withstand higher design pressure than our other Thermacore® models.

• Extra Heavy Duty Thermacore® Insulated Sectional Steel Doors feature one of the best overall air infiltration ratings in the industry – as well as a Class 26 sound transmission rating. They're ideal for heavy-duty applications where both thermal efficiency and sound suppression are desirable.
• Heavy Duty Thermacore® Insulated Sectional Steel Doors meet or exceed almost any thermally efficient application requirement. These heavy-duty doors fit a wide range of opening sizes and the spectrum of applications. The models available in the Heavy Duty line feature a thermal barrier that withstands extremely hot or cold climates along with some of the best overall air infiltration ratings in the industry.
• Medium Duty Thermacore® Insulated Sectional Steel Doors feature a ribbed, textured surface that offers both energy efficiency and attractiveness. This variety comes with wood-grain textured exteriors.
• Light Duty Thermacore® Insulated Sectional Steel Doors are well-built doors that provide a higher level of thermal protection than standard insulated doors. These doors are a good choice for projects where economy and energy efficiency are equally important.
