Horticultural Uses of Perlite

Perlite is a staple in the gardening world, known for its lightweight and porous nature. This makes it excellent for improving soil aeration, drainage, and moisture retention. In gardening,

• Soil Aeration: Perlite particles create air pockets, allowing for better oxygen exchange.
• Moisture Retention: Helps in retaining the right amount of water for plants, preventing overwatering.
• Seed Starting and Rooting: Ideal medium due to its sterile and neutral pH.

Did you know? Perlite is an essential component in potting mixes and hydroponics, offering a perfect environment for plant growth.

Construction Applications

Lightweight and fire-resistant, perlite enhances building materials. In construction,

• Insulation Material: Acts as a lightweight aggregate in concrete, providing excellent insulation properties.
• Plaster and Mortar Additive: Increases fire resistance and decreases the weight of these materials.
• Soundproofing: Effective in acoustic insulation for walls and ceilings.
