Insulating Glass Sealants
Smart hot melt sealants for insulating glass sealant
A suitable sealant can address these pain points. Based on hot melt butyl technology, our IG sealants provide:
- Improved overall sustainability due to low VOCs and reduced waste
- Extended product durability due to excellent barrier performance, slum resistance after application and low thermal conductivity
- Increased productivity due to automation opportunities and reduced production steps
- Increased design options due to compatibility with complex shapes
- Enhanced end-user comfort with strong thermal insulation
- Heightened operator safety due to low argon gas permeation, low moisture vapor transmission rates and no hazardous substances

Frequently Asked Questions
An Insulating Glass Unit (IGU) is an assembly consisting of (at least) two panes of glass, separated with a spacer bar and sealed in its outer perimeter to limit the penetration of moisture into the cavity and improve noble gas retention (if used). High-performance thermal insulated glass enhances the energy efficiency of windows by significantly reducing heat loss.
Insulated Glass Units (IGUs) are produced using manual or automated/robotic processing lines.
The spacer is positioned between the two panes of glass (using a PIB butyl primary sealant in case of rigid hollow spacer bars which have previously been filled with desiccant to absorb the remaining moisture trapped in the cavity), and the outer edge is then sealed with a secondary sealant.
In some cases, Argon gas is used to fill the insulated glass cavity before it is sealed to improve the IGU's thermal insulation performance further.
Bostik hotmelt IG sealants are:
- Fast: easy to use (no purging/no waste), and instant seal (no curing)
- Adaptative: manual or automatic application, works with all spacer technologies and windows shapes
- Durable: best moisture barrier and best gas retention, slump resistance after application
- Efficient: best thermal insulation properties
- Safe to use: no mixing/no chemical reaction
Safety expectations are taken into account at Bostik. We take great care to develop durable adhesives that comply with regulations, with safer materials, and at home. Bostik adhesives are odorless (vs. polysulfides) and don't contain hazardous substances such as isocyanates, heavy metals, or plasticizers.
Bostik offers specialized sealants for insulating glass that enhance thermal efficiency2. Their hot melt sealants help retain gas and create a "warm edge effect," improving insulation. These sealants also act as moisture barriers, prolonging the lifespan of insulated glass units. If you're looking for energy-efficient solutions, Bostik's insulating glass products might be worth exploring.
Insulated glass has several drawbacks to consider:
- High Initial Cost: It is more expensive than single-pane glass, though it can save money in the long run through energy efficiency.
- Sealant Issues: If the seal is compromised, moisture can enter, leading to fogging and reduced insulation performance.
- Limited Soundproofing: While it does reduce noise, it may not be as effective as specialized acoustic glass.
- Weight and Complexity: Insulated glass is heavier and requires careful installation, which can add to labor costs.
- Water Repellent: Helps rain, water, and condensation bead off the surface—great for car windshields and windows.
- Prevents Stains: Blocks hard water marks, soap scum, and mineral deposits, especially in bathrooms.
- UV Protection: Some sealants protect against sun damage and fading over time.
- Ease of Cleaning: Dust, fingerprints, and grime become easier to wipe away.
- Improves Visibility: By keeping glass clearer, especially in automotive or marine use.
