ProPink L77 Pink Loosefill

Leave it to Owens Corning, the pioneer of fiberglass, to create a new fiber, loosefill product and manufacturing process that is so efficient and versatile, it is revolutionizing the industry. 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!”

Use as part of the ProPink® Complete™ System. • Less time = more money: ProPink® L77 Loosefill saves you time and money. It’s also designed for easy install with nearly any blowing machine and can reduce blow time.
