Thermomass

Thermomass is now a proud product brand of Leviat, uniting decades of pioneering concrete insulation technology with today's global leader in engineered construction accessories.

A 50-year History of Success

Thermomass systems create building envelopes that are safe, energy-efficient, and practically maintence-free - just a few of the many reasons why Thermomass has been used in thousands of precast, tilt-up, and cast-in-place projects around the world, from single-family homes to world-class stadiums.

Core Benefits

Learn why leading architects and engineers specify Thermomass systems for mission-critical structures worldwide.

Thermal Performance

Mitigates thermal bridging, delivering code-exceeding insulation capability for high-performance envelopes.

Durability and Longevity

Sandwich panels are built outlast traditional construction methods, protecting insulation - and your investment - for a lifetime of resilience.

Energy Savings and Sustainability

Significant reduction in HVAC operational costs and clear contributions toward LEED, BREEAM, and Passive House certifications.

Ease & Speed of Installation

Engineered connectors and precision-cut insulation streamline placement whether in the precaster's factory or on-site.

APPLICATIONS

THERMOMASS SYSTEMS ARE DESIGNED FOR THE WAY YOUR TEAM BUILDS

Suitable for virtually any project type, Tilt-Up construction provides a number of cost-saving benefits.

Insulated tilt-up construction is an economically efficient way of casting wall panels with the Thermomass insulation systems. Panels are produced on-site by using the building floor slab as the primary casting surface. This eliminates the cost of transporting panels to the site, plus it uses local materials and labor.

In tilt projects, the exterior layer of concrete is poured first and leveled. Then the pre-fabricated, pre-drilled insulation sheets are arranged on top of the plastic (unhardened) concrete according to the individual panel drawings. Thermomass connectors are inserted through the predrilled holes. After placing lifting devices, bracing inserts and required reinforcement, the structural wythe is poured.

Once cured, these panels are lifted into place to form the building envelope. The high strength of the Thermomass connectors hold the sandwiched layers of concrete and insulation secure during the entire process.

Precast panels are produced in a controlled factory environment and shipped to the job site.

Insulated precast concrete panels are cast into a specific shape at a location other than its in service position. The concrete is placed into a form, typically wood or steel, and cured before being stripped from the form, usually the following day. These components are then transported to the construction site for erection.

Thermomass systems have been used in precast wall panels since 1980, with the first uses being in agricultural and cold storage applications.

Insulated cast-in-place construction offers fire resistance, low maintenance costs and protection against above and below grade pest infestation.

When paired with Thermomass insulation, modern cast-in-place building techniques produce highly energy-efficient, load-bearing, insulated concrete walls. System CIP fiber-composite connectors and rigid insulation virtually eliminate the thermal bridges often found in other poured wall and vertical-cast methods.

In addition, Thermomass insulation can be placed into almost any forming system and can be used with or without form liners or brick forms. Local concrete contractors across the country have successfully implemented Thermomass insulation into foundations and poured-wall projects. Larger projects, including museums and churches, have also benefited from integral insulation from Thermomass.
