Building for durability is building for the long term, and for the unforeseeable. We can work with your specifications to achieve your performance goals.

Q&A from the Experts

  • 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.

  • 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.

  • 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.

  • How does polyurethane improve durability?

    BASF's custom-formulated rigid foams and glass sphere syntactic foams offer lower K-factor insulation, which is critical to maintaining oil flow with longer, more complex pipelines in deeper ocean environments. BASF cast and spray elastomers also improve pipe corrosion and abrasion resistance. For deep water applications, BASF offers a unique glass sphere syntactic foam that is capable of withstanding deep sea ocean pressure and higher oil temperatures while offering very low K-factor.

  • What are the benefits of polyurethane adhesives for construction?

    BASF polyurethane adhesives provide exceptional bonding to a wide variety of substrates, over a significant range of temperatures. They help cut time, labor, construction and assembly costs. They work well with other BASF polyurethane chemistries and are available with the same industry-leading technical service support.

  • What formulas are available for construction?

    Wide-ranging one- and two-component formulas are available, based on physical property or processing needs. Adhesives can be made to a range of hardness, elasticity, water or chemical resistance, or wide temperature range performance. Formulations can react to create the strongest possible adhesion to wood, or to bond other substrates such as EPS, OSB or specific metals.

  • Are polyurethane adhesives for construction environmentally responsible?

    BASF offers adhesives that are 100% solids, containing no solvents or volatile organic compounds (VOCs).

  • How do I choose between Lupranate® M20FB and Lupranate® M20SB isocyanate woodbinders?

    A recent BASF fast binder study compared the two formulas using aspen at a face/core/face ratio of 25/50/25, platen temperature of 210 C and 1% wax emulsion for all panels. Test panels included 7/16" (2.5% PMDI dosage), 23/32" and 1" (both 4.5% PMDI dosage). The results showed that Lupranate M20FB reacts faster and gives stronger bonding. However, moisture content was found to be very important. FB with 4% MC was faster than SB, and FB with 6% MC improved performance.

  • What are the benefits of polyurethane elastomers for construction applications?

    Elastocast polyurethane elastomers have exceptional tensile, tear and elongation properties, which makes them an ideal solution for reinforcing building panels or metal construction of any kind. They're stable over wide ranging temperatures and can be made highly resilient to impact, abrasion, cutting or tearing. They also can be filled for additional physical properties and to lower system cost. Spray-applied elastomers are often used in composites to add strength, protection or aesthetics to other materials. Good elongation and anticorrosion properties make cast elastomers well-suited for pipe coatings. And formulations that require resilience and tear strength properties are ideal for molds and concrete stamps. You'll also find them being used on expansion joints in bridge construction, in rail applications for highway crossings and for rail spike adhesives.

  • Are polyurethane elastomers versatile?

    BASF elastomers can be molded to almost any size, shape and texture. This makes them well suited to producing everything from wristwatch straps to molds for simulated stone and outdoor decking to retail store mannequins.
