EPS Insert Block.


EPS insert blocks are staples of masonry construction and form the basis of most construction methods in use today. Architectural blocks with high thermal performance are some of the most sought-after products for a variety of construction projects.

Forma Polystyrene Factory in Qatar produces EPS insert blocks that provide regular concrete blocks with thermal insulation and fire retardation. Take a look at how our insert blocks can upgrade your project.

Let’s Start with Ease of Handling

Expanded polystyrene, or EPS for short, is an incredibly light material. It’s mostly air, making it lighter than any other material that offers low thermal conductivity.


  • > Lightweight
  • > Ease of handling
  • > High thermal insulation properties
  • > Low thermal conductivity
  • > High compressive strength
  • > Low moisture and water absorption
  • > Fire retardant
  • > Environmentally friendly


  • > Concrete blocks insulation
  • > Shape moulded to the exact dimensions of concrete blocks

Lightweight EPS insert blocks are quite easy to handle and don’t add much to the weight of the block itself. Unlike many other insulation materials, EPS is both light and affordable, making it time-efficient and cost-effective.

Since they’re so easy to handle, EPS insert blocks have excellent installation efficiency and very low installation times. You won’t even notice they’re there, yet they’ll provide your masonry construction with increased energy efficiency that few other materials can match.

R-Value that Lasts

With an average R-value of 3.6 per inch, EPS has high thermal insulation properties and low thermal conductivity.

That’s not the best part about our EPS insert blocks, though. Their long-term R-value is almost identical to the insert block’s initial R-value.

Our team produces EPS insert blocks that retain their thermal performance throughout the years. It’s a sound investment into block insulation that will outlive all other materials.

Dimensions of Our EPS Insert Blocks

At Forma, we produce EPS insert blocks in all the standard shapes and block sizes. The dimensions of our blocks are 40cm x 20cm with thicknesses of either 6cm or 7.5cm.

We do block molding depending on the concrete block design. All you have to do is give us the specifications, and we’ll make some insert blocks for you to fill the block cavities.

High Compressive Strengths

Concrete blocks exert a great amount of pressure that normal insulation materials can’t withstand. EPS insert blocks, however, are far more resilient and boast high compressive strength.

Our EPS insert blocks won’t break under the immense pressure of concrete. They will stay in place and keep the building insulated and the energy costs to a minimum.

Fire Retardation

It’s extremely important for insulation material to be fire retardant. Otherwise, it poses a risk that can put the entire building in danger.

Most construction methods nowadays rely on fire-retardant insulation materials, and so should you. At Forma Polystyrene Factory, we produce fire-retardant EPS by adding a special chemical to raw materials that EPS insert blocks consist of.

Application of EPS Insert Blocks

The main application of EPS insert blocks is insulating regular concrete blocks. In doing so, you’re insulating your exterior wall as well. Block insulation is achieved by molding the shape to the exact dimensions of concrete blocks.

You can reduce the energy costs of a building using block insulation on its own, or as an added layer of thermal insulation. Moreover, installation efficiency is another strong suit of EPS insert blocks and an excellent reason to use them.

Get The Best Filler for Block Cavities

Low cost, fast installation times, and high-quality insulation are hallmarks of EPS insert blocks. High compressive strength and fireproofing only make them better, without even mentioning that EPS is environmentally friendly. Recycled content is far more sustainable.
