Block Fill Insulation 24# Bag
Ryolex is a high-performance, industrial-grade expanded perlite designed to provide superior thermal insulation and energy efficiency for a wide range of applications. Created by heating crushed perlite until it expands into lightweight "macroparticles" with a multi-cellular glass structure, this all-natural mineral is non-combustible, non-toxic, and non-carcinogenic. Its unique ability to flow easily into odd-shaped spaces makes it an ideal loose-fill solution for masonry and cinderblock walls—reducing heat transmission by 50% or more—as well as for chimney linings, under-slab insulation, and cryogenic environments. With a high fusion point of 2300°F and a chemically inert profile, Ryolex offers a sustainable, low-density insulation choice that significantly boosts R-values while ensuring long-term structural safety.

Concrete Calculation Disclaimer:
Calculations provided by this tool are for estimation purposes only. Actual yardage may vary due to site conditions, such as uneven subgrade or bulging forms. To ensure you have enough material, it's recommended to add an additional 1/4 to 1 cubic yard to the calculator results. Depending on the subgrade's levelness, larger pours of 20 yards or more may require up to 10% additional.
