Residential Insulating Glass

Enhance the quality and long-term performance of IG units with proven silicone

DOWSIL™ Brand insulating glass sealants, used in conjunction with a polyisobutylene (PIB) primary sealant, consistently outperform non-silicone sealants in areas critical to the long-term performance if IG units.

GAdvantages of IG units with DOWSIL™ silicone sealants

  • Excellent UV and weathering resistance
  • Superior long-term durability
  • Exceptional unprimed adhesion to most substrates
  • Unmatched service temperature range
  • Low shrinkage

Sealants designed to meet application and performance challenges

Dow offers a range of insulating glass sealant options, including one-part and fast-curing two-part neutral-cure sealants for use as secondary seals in:

  • Dual and triple IG units
  • Gas-filled IG units
  • IG units that incorporate specialty glass types
  • Environments where high heat or humidity is encountered
  • Cold climate environments
  • Heat mirror applications

Insulating glass sealants and adhesives with distinct advantages
