{"product_id":"block-fill-insulation-24-bag","title":"Block Fill Insulation 24# Bag","description":"\u003cp\u003eRyolex 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.\u003c\/p\u003e","brand":"Jones \u0026 Sons","offers":[{"title":"24# Bag \/ Washington","offer_id":47521847279865,"sku":"BFI.01","price":18.66,"currency_code":"USD","in_stock":true},{"title":"24# Bag \/ Bloomfield","offer_id":47521847312633,"sku":"BFI.05","price":18.66,"currency_code":"USD","in_stock":true},{"title":"24# Bag \/ Terre Haute","offer_id":47521847345401,"sku":"BFI.07","price":18.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0786\/2507\/9545\/files\/BlockFillInsulation.jpg?v=1779380054","url":"https:\/\/jonesandsons.com\/products\/block-fill-insulation-24-bag","provider":"Jones \u0026 Sons","version":"1.0","type":"link"}
