Insulated Metal Panels

Building in Energy Efficiency

The changing needs of the building industry are driving demand for construction materials that contribute to the energy efficiency of buildings, help reduce their carbon footprints, and meet more stringent fire performance regulations. Metal panels insulated with Dow VORATHERM™ polyisocyanurate and VORACOR™ polyurethane systems for insulated panels and boards bring excellent performance and light weight properties that can meet the most demanding industry requirements, improve longevity and increase energy efficiency.

Efficient, Fast and Reliable Conversion to PIR
While the growing influence of sustainable building initiatives emphasizes energy efficient construction materials, both national regulations and insurance companies have become more stringent regarding fire performance of insulation materials. In order to capture opportunities in this changing competitive climate, sandwich panel producers need to improve the fire performance of their products without affecting their thermal insulation performance.

Polyisocyanurate (PIR) rigid foam offers the best-in-class insulation performance of polyurethane (PUR), but with greatly enhance fire performance properties. Dow’s family of PIR products - VORATHERM™ polyisocyanurate - offers a wide index of fire-performance levels that be further customized to your specifications, allowing you to keep pace with changing market requirements.

Composite Building Panels with HFFR Core Layer Compounds Based on Elvaloy® AC

HFFR core compounds based on Elvaloy® AC acrylate copolymer can deliver superior flame retardancy and sound deadening in composite building panels.
Dow offers a complete system for halogen-free flame retardant (HFFR) composite panel core layers including Elvaloy® AC base polymer, a technology license that can help protect your innovation, and complete technical support to tailor the composition to specific requirements.

HFFR Core Layer Compounding Efficiency
Elvaloy® AC has excellent compatibility with low-cost fillers such as CaCO3, ground ATH and ground Mg(OH)2. Your resulting flame retardant, sound deadening core compounds can be highly cost competitive compared to other conventional HFFR technologies.
One of the ways to further assure proven performance of a filled compound is to use a proven coupling agent such as Fusabond® functionalized polyolefin.

PE-Aluminum Adhesive Choices with Bynel®
PE-aluminum adhesive performance is one of the most important requirements for aluminum composite building panels to remain attractive and trouble-free after installation. Because delaminations can be a particularly unsightly and costly repair issue, panel manufacturers must take great care to assure long-term adhesion between the panel core material and outer metal layers.

PE Aluminum Adhesive Placement Alternatives
Dow offers several specially developed grades of Bynel® adhesive resin for use in laminating building panels. Bynel® resins have been proven effective in a variety of adhesive placement methods (prior to or simultaneous with the aluminum lamination step):

  • Coextrusion with the polymer core;
  • Lamination with a pre-made film of Bynel®
  • Extrusion coating onto the polymer core layer.

The panel manufacturer's choice of adhesive placement technology typically dictates an ideal processing temperature to maximize panel adhesion without damaging color or surface appearance. Bynel® resins are offered in high-performance grades that can be tailored to each manufacturer's processing requirements.
