What is Fiberglass Insulation?

What is Fiberglass Insulation?

Fiberglass insulation is thermal insulation made from fine glass fibers. The glass fibers are created by melting silica sand and other materials, then spinning them into thin strands. These strands are often bound together with a resin and formed into batts, rolls, or loose-fill insulation.

Why is Fiberglass Laminated?

Why is Fiberglass Laminated?

It is primarily laminated to enhance moisture resistance and structural integrity. In addition, it improves thermal performance and energy efficiency in buildings.

What is R-Value?

R-value shows how well a material blocks heat. The higher the R-value, the better the insulation. Thicker layers of insulation provide greater resistance to heat transfer by keeping heat in during winter and out during summer.

R-Values: R - 8 ( 2.75") | R - 10 ( 3") | R - 11 (3.5") | R - 13 (4") |

R -19 (6") | R -25 (8") | R - 30 ( 9" )

What R-Value Should I Choose?

What R-Value Should I Choose?

Different regions require different R-values based on climate. Warmer areas need less insulation than colder climates. If you're adding insulation to an existing structure, consider the current R-value. If you're aiming for specific energy savings or to meet green building standards, choose a higher R-value. Higher R-values often come with increased costs.

Fire Performance

Our insulations have a Class A/Class 1 Fire Ratings.

NAIMA

This independent test, conducted by Home Innovations, ensures top-quality performance. By laminating the facing to the fiberglass, it maintains its integrity and achieves the specified R-value upon unrolling. While some manufacturers rely on in-house testing, NAIMA 202-96 fiberglass guarantees the R-value you expect, delivering consistent, reliable performance every time.
