Tru-R Insulation for Construction.
In the construction industry, Tru-R is among the most versatile, energy efficient, and cost effective insulators available, delivering extremely high, stable R-values. Depend on Tru-R to do the job—practically any job—from the ground up: perimeter foundation and underslab insulation, wall sheathing, EIFS insulation, roof insulation, concrete insulation/void filler, and ICF insulation.

Molded Polystyrene Insulation
Stands up to the elements, yet it’s good for the environment.
Cost effective thermal design is among the highest priorities in construction. Tru-R insulation products are available in a range of densities necessary to provide energy efficiency, structural integrity, and cost effectiveness. They’re proven to lower energy costs, saving both money and precious resources.
Thermal Performance.
Cost effective thermal design is among the highest priorities in construction.Thermal resistance (R-value) of an insulation assembly is the determining factor in thermal performance. Tru-R provides optimum cost value when compared to other rigid insulations of the same R-value design.
Strength Characteristics.
Tru-R insulation products are available in a range of densities necessary to provide both structural integrity and cost effectiveness. Other rigid insulation products fail to provide this design flexibility due to limited density availability, and therefore cost more.
Construction Applications

Architectural Shapes
Tru-R gives you control over the design of your project. You determine the shape and specs of the components you need, then Thermal Foams works with you to custom fabricate your design by hot wire cutting with computer aided design (CAD).

Cavity Wall
Tru-R is a cost-effective, durable, and energy efficient solution for cavity wall applications. It is an ideal material to stop energy loss in brick faced residential and commercial masonry and framed walls.

Concrete Applications
Tru-R for poured-in place and precast concrete systems reduce the requirement for concrete and overall weight. Tru-R can been used as: concrete sandwich panel cores, block-outs/knock-outs, void fillers, custom pattern forms, and more.

Crawl Space
Tru-R can been used as: concrete sandwich panel cores, block-outs/knock-outs, void fillers, custom pattern forms, and more. Tru-R is a cost-effective, durable, and energy efficient solution for interior crawl space wall applications.
Exterior Sheathing
Tru-R has superior moisture resistance, breathability, and stable R-value to protect your insulation integrity. It is an ideal material to stop energy loss through framing members.
Perimeter & Under-Slab
Tru-R with borate is a cost-effective, durable, and energy efficient solution for below grade insulation applications. It is an ideal material to stop energy loss at the foundation or slab. Tru-R with borate is a proven material with built in protection against the destructive force of termites.
Protection Boards
Tru-R Protection Boards are economical, light weight and easy to install over foundation walls that have been damp-proofed or water-proofed with coatings/membranes. Installed prior to backfilling, Tru-R Protection Boards provide impact puncture protection for foundation wall coatings/membranes from rocks and potential construction debris in backfill soil. Protection is also provided against crushed stone/gravel used in many foundation drainage designs. In cold regions, Tru-R Protection Boards bond-break the soil from the foundation wall and as insulation reduces potential damage of freeze thaw cycling.
Radiant Floor Boards
Tru-R is a cost-effective, durable, and energy efficient solution for insulation applications. It is an ideal material to stop energy loss. Tru-R Radiant Floor Boards for use in radiant floor systems are provided in two configurations:
4’ x 4’ boards with 3” on center slots for fast installation of PEX tubing in hydronic radiant systems
4’ x 8’ flat sheets for use in electric radiant systems
Nailbase
Tru-R Nailbase consists of Exposure I rated Oriented Strand Board (OSB) and UL Classified Tru-R rigid insulation. It is an ideal insulation and nailable surface for structural roof decks and walls. Stability and traffic resistance make Tru-R Nailbase perfect for both residential/commercial roof decks and walls.
Nailstrip
Tru-R Nailstrip consists of factory installed furring strips and UL Classified Tru-R rigid insulation. It is an ideal insulation and nailable surface when applied over structurally sound walls such as poured concrete, concrete block, brick, wood and streel framing. Stability makes Foam-Control Nailstrip perfect for both residential and commercial wall applications.
Tru-R Roofing
Tru-R Roof Insulations offer versatility for use in virtually all Roofing Membrane Systems. Tru-R can by supplied as flat board stock, tapered, unfaced, or with factory applied facings or coverboards.
In the roofing industry, Tru-R Roof Insulations are among the most versatile, energy efficient, and cost effective insulators available, delivering extremely high, stable R-values. Depend on Tru-R to do the job as flat stock or tapered with labor-saving factory or field applied face laminates. Tru-R is ideal for use in fully adhered, mechanically fastened, or ballasted TPO, PVC, EPDM, and other single ply membranes as well as modified bitumen and built-up roofing.
