What are the load-bearing capabilities of PIUR Panels?

PIUR Panels load bearing capacity is superior to that of typical wood frame and comparable to bearing capacity of metal frame buildings. A typical 9 feet heigh and 4 feet wide PIUR Panel with 3.0" polystyrene core and 1.125” concrete shell on each side has been tested at a load of over 450,000 Ibs.

Why are PIUR Panels Green?

PIUR Panels' foam core is 70 to 100% re-ground foam, depending upon local manufacturer's capacity. The wire mesh is 40% recycled steel (autos, etc.) and the concrete skins are a minimum of 40% coal fly ash. The insulation (core) and

exterior concrete skin isolate the interior skin from the effects of the outdoor temperature, permitting a true thermal

flywheel behavior by the interior skin.

How do I purchase PIUR Panels?

Architects, designers and builders can purchase PIUR Panels from our network of PIUR Panel Certified Builders. If you do not see a certified builder in your area call our office at 818-252-1360 and ask for our sales department.

What is the fire rating on PIUR Panels?

PIUR Panels have reinforced concrete skins of a minimum thickness of 1” (25mm), which means that our panels will have a minimum 90-minute fire rating. In other words, PIUR Panels will resist 1800 degrees Fahrenheit for up to 90 minutes. The concrete skins can be thickened to increase this rating up to four hours.

Are PIUR Panels Waterproof?

PIUR Panels can be waterproofed. The most common methods are either with crystallizing additives in the mix such as

Xypex, Kryton, or surface treatments. The surface treatments range from membranes (elastomeric, rubber, etc.) to surface applied materials that result in a change in the concrete to create a waterproof skin.

What codes do PIUR Panels comply with?

PIUR Panels are designed in conformance with the American Concrete Institute ACI 318 standard. This means that designs employing PIUR Panels will comply with just about any building code, IBC, SBCC, BOCA, etc.

How are pests controlled in PIUR Panels?

None of the materials in PIUR Panels provide food for pests and vermin. Although the plastic EPS core can provide habitation and/or nesting material, because it is fully enveloped in concrete it is generally inaccessible to pests and vermin.

Can shotcrete or gunite be used to apply the concrete skins to PIUR Panels?

Dry-mix pneumatically placed concrete is the preferred method of applying concrete skins to our panels; however, the

concrete skins can also be applied by hand, machine plastering techniques, or shotcrete, wither wet-mix or dry-mix

(gunite).

How are electrical and plumbing installed in PIUR Panels?

PIUR Panels can have open space in the foam layer, which is ideal for passing electrical conductors and pipes in any

direction within the wall.

What is the insulation R-Value for PIUR Panels?

The "R" system is a method of calculating the resistance of building materials to the transmission of heat. Because PIUR Panels are heavier than wood frame and they can store and emit heat, for the same R-Value their

performance is superior to that of the wood frame construction. The R-Value of PIUR Panels is usually 25+ for

walls and 40+ for roofs.
