Structural Insulated Panels (SIPs) in Construction

While currently a rather small market, structural insulated panels, or SIPs, are forecast to gain popularity now through 2022. Therefore, it’s important industry professionals gain better understanding into this relatively new market.

Take a look at what they are, their benefits and the role sealants play in their installation.

What are SIPs?

SIPs are high performance building systems for both residential and commercial applications. Comprised of two outer substrates and a core in the middle, they are manufactured in controlled settings and can be used as panels in nearly any building design.

The outer substrates typically consist of the following materials:

  • Oriented strand board
  • Plywood
  • Steel
  • Aluminum
  • Glass fiber reinforced polyester

The core is commonly manufactured out of:

  • Expanded polystyrene
  • Polyurethane foam
  • Phenolic foam
  • Aluminum honeycomb

The insulated panels are then used in the following applications:

  • Garage and industrial doors
  • Walls for prefabricated houses
  • Suspended ceilings

Benefits of Using SIPs

Like prefabricated construction, they help reduce onsite construction time, cost and requirements. By being manufactured in a controlled environment ahead of time, it also leads to enhanced jobsite worker safety.

Additionally, by providing high levels of air tightness and insulation, these panels  improve energy efficiency and structural stability.

Sealants in SIPs

Sealants enable SIPs to offer high levels of energy efficiency. In addition to sealing the structure and protecting it from the elements, sealants provide an airtight envelope. To do this, sealants must:

  • Be flexible and resilient
  • Not crack or tear

Bostik manufactures smart sealants for a variety of construction applications. For more information on how our sealants improve construction projects overall, call 800-7-BOSTIK, or visit www.bostik.com.
