  • What is fiberglass insulation? Fiberglass insulation consists of extremely fine glass fibers, sand and is the type of insulation found in most homes. It is commonly used in two different types of insulation – blanket which is batts and rolls, and loose fill. Fiberglass can be placed in unfinished walls, floors and ceilings. It is fitted between studs, joists, and beams.
  • Fiberglass as an insulator slows the spread of heat, cold, and sound in structures. The material does this by trapping pockets of air, keeping rooms warm in the winter and cooler in the summer.
  • An often overlooked feature of fiberglass insulation is that it is eco-friendly, which is particularly important if you are worried about your carbon footprint. It is made out of sand and recycled glass, both of which are renewable resources.
  • Fiberglass insulation is also non-combustible, non-absorbent and non-corrosive. It will not hold water, so you never have to worry about moisture issues as a result of this type of insulation.
  • Fiberglass insulation is cost-effective but also gives you year-round comfort. You and your family will be warm and toasty in the winter and cool and comfortable in the summer thanks to fiberglass.
  • The type of fiberglass insulation we install is mold and mildew resistant. So you will not have to worry that your new fiberglass insulation is retaining moisture.
  • Fiberglass insulation is also budget-friendly. You still get many of the same perks as other types of insulation, but fiberglass is one of the least expensive options on the market today.
