The insulation of clothes are often measures in the unit "Clo", where
CLO = 0 Corresponds to a naked person
CLO = 1 Corresponds to the insulating value of clothing needed to maintain a person in comfort sitting at rest in a room at 70° with air movement of 0.1 m/s and humidity of less than 50%
When it comes to cold weather PPE, you’ll see many manufacturers offering temperature ratings or guarantees on insulated winter safety gear. Trusting a universal temperature rating isn’t a good idea. There are too many outside factors that can affect a worker’s ability to combat cold weather.
At HexArmor®, we rely on science.
To measure thermal properties, the C-L-O, or CLO rating system has been the standard for decades. The CLO scale is used to measure the warmth levels of various materials, including thermal protection like Thinsulate™.
3M™ Thinsulate™ Insulation is warm yet lightweight, powerful yet thin. It helps trap and holds body heat, while allowing moisture to escape. The extremely fine microfibers in Thinsulate insulation help trap air and block body radiant heat loss, making it an efficient insulator. The high warmth-to-thickness ratio of this insulation enables garment designs with less bulk and enhanced freedom of movement.
C40 Thinsulate® is a high-activity liner designed to perform well on hands frequently in motion. It offers an exceptional level of protection again the cold elements for most of the United States, except in most extreme conditions. C40 is ultra-thin, stopping hands from sweating or overheating.
C100 Thinsulate® performs well in slightly colder conditions where more warmth is needed for those who are working in lower temperatures, depending on the activity level on the job. It’s rapidly becoming the choice for harsher conditions, such as those found in parts of Canada, North Dakota, and Alaska.
Workers’ warm breath and body heat contrast with the cold climate, causing safety glasses to fog up in an instant. This results in workers having to take their glasses off to see, subjecting them to potential hazards and compliance issues.
Chemically engineered to NOT wash off, HexArmor’s TruShield®2F and TruShield®2SF offer permanent anti-fog coatings on the inside and outside of the lenses that are four-times thicker than the competition to protect against moderate to heavy fogging on the job.
