What is the main purpose of thermal insulation?
The primary purpose of thermal insulation is to minimise heat flow, whether it’s preventing heat from escaping a heated space (such as a building during winter) or preventing heat from entering a cooled space (such as a building during summer). With time, your insulation settles and loses its thermal resistance or R-Value depending on the material. This reduces the efficiency of your insulation and may result in inflated energy expenses.R10 insulation provides significantly better thermal resistance than R5 insulation. This means it is more effective at keeping heat in during the winter and out during the summer, which can lead to greater energy savings.Injection foam and spray foam typically offer high R-values, making them excellent choices for homes in hot climates. However, it’s important to consult with an insulation professional to determine the best R-value for your specific location and home design.Typical R-values range from R13 to R60, although some products may offer higher or lower values. The higher the R-value, the better the insulating power of that material. R-values are based on the thickness and density of the material.
What is the highest thermal insulation material?
Out of all types of insulation, aerogel has the highest R-value per inch of thickness, meaning less material is required to do a better job of preventing heat transfer into or out of a building. Solarcore® utilizes the thermal advantages of Aerogel – the NASA licensed material used to insulate spacecraft in the -450° F vacuum of space.
What is the lifespan of thermal insulation?
Cellulose insulation: Made from recycled paper, cellulose insulation has a comparable lifespan to fiberglass insulation, lasting 30-40 years. Spray foam insulation: Spray foam offers excellent thermal resistance and air sealing properties. With proper installation and maintenance, it can last between 40-80 years. Polyurethane “Spray” Foam: 80+ years Polyurethane foam (spray foam) insulation can last a lifetime with proper maintenance. The material withstands major variations in temperature and moisture, with the more dense, closed-cell form having a slight edge in effectiveness and durability.
