# Fiberglass Insulation

## Thermal conductivity of fiberglass insulation - temperature and k-values.

Fiberglass is made of molten glass spun into micro fibers and is one of the most common types of insulation used.

Fiberglass thermal conductivity vs. temperature are indicated in the charts below:

• T(oC) = 5/9[T(oF) - 32]
• 1 W/(m K) = 6.935 (Btu in)/(h ft² °F)
