Icon Universal Inserts

Icon Universal Inserts

ICON Inserts are molded from expandable polystyrene. The design of the insert allows it to compress so it will fit the cores of all masonry units with just one size. Inserts are placed in the cores of the block at the block plant. By placing inserts in blocks, there is a significant improvement in the thermal efficiency of masonry walls.

Korfil Hi-R Masonry Wall System

Korfil Hi-R Masonry Wall System

The Hi-R Wall System is a specially designed concrete masonry unit and individually molded insulation insert. The block and the insulation are combined at the block manufacturing plant prior to delivery to the job site. The assembly provides a wall system capable of achieving higher thermal R-values than conventional masonry, with no effect on the structural integrity of masonry construction.

Hi-R-H Energy Efficient Wall System

Hi-R-H Energy Efficient Wall System

HI-R-H are pre-insulated fully grouted masonry wall systems that offer superior thermal performance. Double exposed single wythe masonry walls with durable architectural finishes for conditioned spaces in all Climate Zones. Hi-R-H half-high units are also available.

Why EPS?

EPS has high R-value retention, is fully recyclable, and is easily customizable. EPS is made without ozone-harming compounds or any kind of dye. It is available in a variety of compressive strengths and has superior bonding capabilities. Best of all, EPS will save you time and money. So the real question is: Why not EPS?

Shaping A More Sustainable World

Sustainability is one of our top priorities, both for our products themselves and for what our products make possible. Manufactured without ozone-damaging compounds, recyclable and endlessly reusable, EPS has a smaller carbon footprint and results in less pollution than the manufacturing of alternative materials. And EPS helps create a more sustainable world by making buildings more energy efficient, reducing greenhouse gas emissions, preventing product damage and waste, and reducing shipping fuel usage, just to name a few. We’re constantly working to find new ways to be good stewards of our customers’ visions and of our environment.
