Styrobar Plus
High quality closed cell rigid foam insulation, with a heat laminated clear film that adds durability, performance and value.
STYROBAR is a high quality, closed cell, rigid foam insulation made from Expanded Poly Styrene (EPS). STYROBAR PLUS is the same high quality rigid foam insulation with the added value of a heat laminated clear film which greatly enhances our product’s durability, performance and value.
Four grades are available, from Type 1 through Type 3, so the panel can be matched to the load and the R-value the assembly actually needs — from cladding under siding through to shallow foundations and grade beams.
- Heat laminated clear film for added durability and performance
- Four grades from 10 PSI to 40 PSI compressive strength
- R-3.75 to R-4.2 per inch depending on grade
- Works above grade, at the perimeter and below slabs
- Custom lengths to 16′ in 1/4″ thickness increments
- Fan Fold and Rolled formats for continuous coverage

More than 4′×8′ sheets
Styrobar Plus is available in more than just 4′×8′ sheets of up to 5″ thick. It can be ordered in sheet lengths of up to 16′ long, in 1/4″ thickness increments. It is also available in:
Fan Fold
Fan Fold Poly Pro is a continuous sheet that is 4′ tall, 3/8″ to 3″ thick and 50′ long. It is then fan folded back and forth into 25 sheets of 4′ by 2′, making a continuous 200 sq ft piece.
Rolled
Rolled Poly Pro is a 4′ wide roll of laminated insulation, available in 3/8″ to 5/8″ thicknesses and 70′ to 75′ long depending on thickness, making each roll a continuous 280 to 300 sq ft piece.
