Building Insulation

Foam board and building insulation

With changing needs in the building industry, today’s construction materials are called on to deliver:

  • Greater energy efficiency
  • Reduced environmental impact
  • Compliance with stringent regulations, such as fire performance

Polyurethane Systems

For insulated panels and boards, we offer polyurethane systems that are lightweight, increase energy efficiency, improve longevity, and meet the most demanding industry requirements.

Surfactants for PUR/PIR

For polyurethane (PUR) and polyisocyanurate (PIR) foam insulation systems, our high-performance surfactants boost energy efficiency. Typical applications include:

  • Foam core laminate
  • Pour-in-place insulation
  • Spray insulation polyol blends

Compatible with polyester and polyether polyol formulations, the surfactants simplify the mixing of polyols and blowing agents, maintain the blowing agents in the emulsion or solution, and provide excellent emulsion stability.

When formulated and processed properly, systems with these surfactants can achieve higher foam yield and higher compressive strength. The surfactants meet the requisite building and fire performance tests, making them ideal when fire resistance is needed.

Acrylic Alternatives

Thermosetting resins from Dow can be used as an alternative to traditional formaldehyde-based resins for binding mineral fibers in the production of insulation blanket products that go into building insulation systems and specialty insulation.
