R-Tech FF meets or exceeds the requirements of ASTM C578, Standard Specification for Rigid, Cellular Polystyrene Thermal Insulation. In addition, R-Tech FF has excellent dimensional stability, compressive strength and water resistant properties.

Nov 16, 2022 · Foam board insulation has around 3.5-5.5 R-value for every inch. However, these numbers may vary according to the variation of the original product being used. Keep on reading if you plan on learning a thing or two about foam board and the R-values of its different forms.

R-Foam foam solves the problem of drafty walls in poorly insulated homes. R-Foam is non-expanding injection foam that can be injected into walls of existing homes. It can be installed from the inside through the drywall or from the outside through the exterior siding or brick.

R-Tech Panels are an engineered rigid insulation consisting of a superior closed-cell, lightweight and resilient expanded polystyrene (EPS) with advanced polymeric laminate facers. R-Tech is available with factory-adhered metallic-reflective facers, white facers or a combination of the two.

Sep 22, 2021 · The R-value of foam board insulation varies on its type but can be as high as 8.0 in the case of polyisocyanurate. Outside of the foam board’s insulating qualities, you have to consider its price, ease of application, and durability as well.

Nov 17, 2023 · In real-world applications, R-value numbers tell you how thick, or how many layers, you need to install your insulation to achieve the proper rigid foam insulation R value required by code. Let’s say you’re installing polyiso on your walls and R-20 continuous insulation is required by code.

What to Expect: The R-value Calculator will guide you through selecting stud types, spacing, and insulation options—like XPS Foamular, Mineral Wool, Spray Foam, or Fiberglass—and provide a total wall R-value based on your inputs.

Nov 16, 2022 · The required spray foam insulation thickness is calculated by dividing the desired R-value with the R-value of the insulation. For eg: For an attic that requires R-21, the spray foam insulation thickness is 21/3.5 if open-cell spray foam is …

EPS R320 is an advanced expanded polystyrene (EPS) grade specially designed for applications requiring rapid molding and compliance with REACH regulations. This EPS grade is suitable for high-quality shape molding and is ideal for food-safe packaging and precise molded components.

Rigid insulation like rigid foam and foam boards have high R-values. That’s why materials like polyiso (polyisocyanurate) , EPS (expanded polystyrene) , and XPS ( extruded polystyrene) like Styrofoam make for such good insulation materials.
