No other loosefill insulation measures up to its coverage, performance, and energy efficiency. PROPINK® L77 LooseFill Insulation leads the industry in thermal performance and yield.


“I like everything about ProPink® L77 Loosefill Insulation. It’s user friendly, easy on our equipment and problem free. It’s the best Fiberglass on the market. There’s no question we prefer it to all other loosefill products. Other manufacturer’s products are lower density, not as easy to use and you need more to get a R-value. I absolutely recommend others to use ProPink® L77 Loosefill Insulation!”
