Construction perlite

For construction — light, warm, safe.

In construction, perlite is valued for its light weight, durability, and excellent insulating properties. Expanded perlite is used as a lightweight aggregate in building mixes, plasters, insulation systems, and specialized construction products where reduced structural weight and improved energy efficiency are essential.

In construction, perlite is valued for its light weight, durability, and excellent insulating properties. Expanded perlite is used as a lightweight aggregate in building mixes, plasters, insulation systems, and specialized construction products where reduced structural weight and improved energy efficiency are essential.

Due to its porous structure, perlite enhances thermal and acoustic insulation while maintaining stable technical properties. It is non-combustible, moisture-resistant, rot-proof, and does not promote microbial growth — making it ideal for long-lasting construction solutions.

Perlite is used in both new construction and renovation. It can be integrated into dry mixes, lightweight concretes, plasters, floor fills, and thermal insulation structures. Its low density reduces structural loads — particularly important in modern, energy-efficient buildings.

Our construction-grade perlite is produced and tested under strict quality standards. We offer different fractions tailored to various construction technologies and manufacturing processes.

Where it's used

What is construction perlite used for?

Lightweight, non-combustible and insulating — construction perlite replaces heavy aggregates and makes buildings warmer, quieter and safer. From ready-mix plants to renovating an old house, the most common uses:

🧱 Lightweight concrete

As an aggregate it cuts the weight of concrete and screeds while adding thermal insulation — ideal for floors, roof decks and precast elements.

🪵 Insulating plaster & render

Warm, breathable cement or gypsum plasters that insulate walls and resist fire.

🏠 Loose-fill insulation

Poured dry into masonry block cavities, wall gaps, floors and lofts — it flows and fills every void.

🔥 Fireproofing

Non-combustible (A1) — used in sprays and boards to protect steel beams, columns and partitions.

🧊 Floor & roof screeds

Lightweight levelling fills that reduce structural load and improve insulation.

🔇 Acoustic insulation

Its porous structure absorbs sound in walls, floors and ceilings.

🏭 High-temperature & refractory

Chimney and flue fills, ovens and kilns — stable up to high temperatures.

🧰 Dry mortars & mixes

A standard aggregate in factory plasters, adhesives, renders and repair mortars.

🏡 Renovation & old buildings

Light, breathable insulation that suits heritage and timber-frame walls without overloading them.
