We’re super excited to introduce our new all-purpose 4 cubic foot plastic bag design, for non-Horticulture product grades. Its black and grey design will make it easier to tell the industrial and construction grade products from our soil amendment grades which still feature the traditional two-tone blue logo and color scheme.

These bags are formed on our state-of-the-art Premier Tech form-fill-and-seal bagging machine, and stretch-hooder, for superior moisture protection.

We’re starting out bagging just our Fine HD lightweight aggregate at this time. Eventually we’ll add other grades. The design is flexible so we can opt to fill different grades using this same package and print the grade on the outside at filling time.

We can also private label for your brand on our equipment. Call us or email [email protected] for a quote on your next project.

Perlite lightweight aggregate is useful for making lightweight insulating concrete, fire resistant building products, minimizing weight, insulating, slab-on-grade insulation, foam free environmentally-friendly construction, passive house construction, refractory bricks and cement mixes, and so much more!

❄️🌡️ Perlite: The Key to Efficient Cryogenic & Low-Temperature Insulation 🌡️❄️

Did you know expanded perlite is an essential material for insulating cryogenic and low-temperature storage tanks? It’s the ideal solution for keeping extremely cold fluids like hydrogen and helium at the right temperature. ❄️

Perlite's unique physical properties make it perfect for use in:

- Cryogenic storage tanks (for temperatures below -150°F / -100°C) 🧊
- Cold boxes, shipping containers, and food processing 🥶
- Double-walled vessels and pipes requiring specialized insulation
- When used in non-evacuated systems, perlite fills the annular space between double-walled vessels, keeping cold temperatures inside and reducing heat transfer. Plus, for larger installations, perlite expansion plants create the insulation on-site, ensuring maximum efficiency.

From super cold fluids to low-temperature storage, perlite is the go-to material for critical insulation. 🌍💡
