For 5 Core Reasons
Developers Pick
Isotex
For 5 Core Reasons
You Save Money
Every hour saved on-site saves you more than time. With Isotex, builds move faster. No mortar. No delays waiting on multiple trades. No layers to add later. Just one system that locks in insulation, fire resistance, and seismic strength from day one. That means fewer surprises. Fewer invoices. And the confidence of a project that stays on schedule and on budget.
Your Build Gets Done Faster
When the structure goes up fast, everything else falls into place. Isotex blocks are dry-laid, lightweight, and simple to install — cutting structural build time dramatically.
No Need For Expert Labour
If you use Isotex you don't have to worry about finding specialised labour. Because any labourer can follow the easy 3-step process to dry laying Isotex blocks.
You Save On Materials
Why haul in pallets of different materials when Isotex does the job? The blocks handle insulation, fire resistance, and seismic safety all at once. No extra layers. No pallets of add-ons. Just one system, one delivery, and a whole lot less to manage.
It's Code Compliant
Isotex meets or exceeds all major building standards: CE Marked under EU Regulation 305/2011 ISO 9001 certified for quality management European Technical Assessment (ETA) approved MEC compliant for public and social construction Fire safety certified (REI 120 / REI 240) Anti-seismic tested and verified Thermal and acoustic standards met (ANIT, EN, CSI) Compatible with LEED, BREEAM, and ITACA protocols
It's Fire Resistant
Isotex provides maximum safety in fires. The data shows that Isotex buildings resist fire long enough to safely evacuate people in the building.
It Can Withstand Earthquakes
Italy is an area prone to earthquakes. But Isotex buildings have withstood major earthquakes without suffering any damage, not even a crack.
Makes It Easy To Meet NZEB Standards
The combination of Isotex blocks and floors allows the elimination of thermal and acoustic bridges. That gurantees superior energy performance and makes it possible to create buildings with the highest energy efficiency classifications: A4, NZEB, and ZEB
