Questions about

Fencing and Decks

 

How does polyurethane foam help fencing and decking last longer?

High-density polyurethane foams used for these applications offer a low H2O absorption rate and moisture-resistance (water absorption rate under 1% by volume) that does not attract mold, fungus, rot or insects. And because it is designed for low maintenance, BASF high density foam can take varying temperatures and climates and maintain appearance.

 

How is polyurethane fencing and decking made?

High-density foams like Elastopor® feature a custom formulation that allows them to be foamed and molded in place—to any shape or design—and then be painted or laminated.

 

Is there any danger of Volatile Organic Compounds (VOCs) in car interiors when using polyurethane foam?

Elastoskin systems and Elastoflex PUR foams boast lowest-in-class volatile organic compound (VOC) emissions—much lower than 100ppm—in any formulation, customized to your specifications.

Questions about

SIPs and IMPs

 

What is the difference between a SIP and an IMP?

A structural insulated panel (SIP) includes a core of insulation sandwiched between two structural skins--usually made of wood or OSB. An insulated metal panel includes a core of insulation sandwiched between two diffusion-resistant metal skins. SIPs tend to be best suited for roof and wall elements in residential or light commercial construction, while IMPs are usually found in larger commercial and industrial construction and specialty applications such as cold storage facilities. IMPs are also sometimes used for residential construction in extremely cold climates.

 

How are SIPs made?

Panels begin life in the factory. CAD drawings of the structure to be built are converted to shop drawings, which are then plugged directly into computer numerical control (CNC) fabrication machines or are used to measure and cut the panels by hand.

Special channels (chases) are cut into the foam to allow for the electrical wiring, and the insulation core is recessed around the edges to accept the connection splines or dimensional lumber used during construction.

 

Do SIPs come in standard sizes?

Standard panels are available in 4’ x 8’ or 8’ x 24’ configurations. Thicknesses typically range from 4.5” to 12.25” but custom sizes and thicknesses are also available. Once manufactured, the panels are shipped directly to the construction site for fast and easy installation.

 

I am considering adding polyurethane foam SIPs to my product offering, can you help me figure out what equipment I need?

BASF offers AUTOFROTH® SL dispensing equipment for polyurethane foam SIPs, with a low capital investment and proven field performance at hundreds of locations across North America. To learn more about getting started with polyurethane SIPs, please contact us.

 

Can SPF roofing reduce thermal bridging?

Because it is seamless and monolithic, SPF roofing provides a single layer of continuous insulation. Because it does not require fasteners, it helps reduce thermal bridging, which in turn improves energy efficiency.

Questions about

Spray-Applied Polyurethane Foam (SPF)

 

What is the difference between open-cell and closed-cell SPF?

There are three major differences. First, BASF uses the versatility of chemistry to offer a closed-cell content of greater than 90 percent for all of its roofing and air barrier formulations, and open-cell foams commonly used as insulation systems have approximately 60 percent open-cell content. Second, closed-cell foam offers an R-value of over 6.0 per inch and open cell offers between 3.0 and 3.9 per inch. Third, closed-cell foam is virtually impermeable to air, while most open-cell foams do not offer the air leakage performance required to qualify as an air barrier. However, open-cell foam is less expensive, and offers better sound absorption.

 

What are the differences between roofing foams, wall foams and sealant foams?

Polyurethane foams are either single- or plural-component products engineered on the molecular level for a specific purpose and application. Roofing foams tend to offer higher compressive strengths and smoother surfaces, while wall foams tend to offer faster reaction rates, higher yield and superior insulation R-values. Sealant foams can be similar in content to wall foams, and are either single-component or plural-component sealants in cans for smaller cracks and finer applications.

 

Are SPF roofs sustainable?

Yes. There are many factors that contribute to the sustainability of SPF roofing systems. First, no tear-off of the existing roof is required in 98% of re-roofing applications, which diverts thousands of tons of waste from landfill. Second, they are extremely durable, offering industry-leading resistance to severe weather including wind uplift and impact from airborne debris. Third, they offer an extremely long life expectancy of 20 years or more, and are renewable indefinitely with simple recoats. And fourth, they make a significant contribution to building energy efficiency. One Texas A&M study showed the university was able to pay for the cost of their new SPF roofs in 4.5 years though energy savings! And when they are combined with reflective coatings, SPF roofing systems also help combat urban heat island effect and reduce smog.

 

Does SPF qualify as an air barrier?

WALLTITE® insulating air barrier system has pass the ASTM E 2357 Air Leakage of Air Barrier Assemblies test and is approved by the Air Barrier Association of America (ABAA). WALLTITE also meets air barrier requirements of the Commercial Energy Codes of Massachusetts, Wisconsin and Michigan. In Canada, WALLTITE technologies have also passed the stringent Canadian Construction Materials Centre (CCMC) requirements for Insulation, Air Barrier Material and Air Barrier System.

 

What is the air permeance rating of closed-cell SPF?

Two-component, closed-cell spray-applied polyurethane foam (SPF) air barriers offer an air permeance rating of 0.000025 l/s.m2 @ 75 Pa (at 0.5-inch thickness), combined with an R-value of 6.7 per inch. A single application gives you air barrier, vapor barrier and insulation in one system.

 

Is SPF roofing durable?

High-quality, well-installed ELASTOSPRAY® SPF roofing systems offer a 20-year life expectancy, and are renewable almost indefinitely with simple recoats. They also offer industry-leading resistance to wind uplift and severe hail, making them among the most durable systems available on the market.

Is SPF roofing an affordable option for retrofits?

Yes, in fact, SPF roofing is the lowest cost re-roofing option in 98% of retrofit projects, because it can be applied to the existing substrate almost every time. That means reduced labor, and with tons of waste being diverted from landfill, disposal fees – and the cost to the environment – are both greatly reduced.

Can SPF roofing help my project gain LEED® points?

ELASTOSPRAY®’s performance can contribute to many LEED® points, especially in the energy categories. In fact, we used ELASTOSPRAY on BASF’s new North American headquarters building, which achieved LEED double platinum!
