Proper adhesion and sealing of insulating glass units (IGU) is a critical part of window and door durability and performance. Primary and secondary sealing of multiple pieces of glass locks out moisture and adds structural stability to insulated glass panels. An accurate desiccant application removes any moisture trapped in the gas space between the glass panes preventing condensation while improving insulating performance. Thermal transmittance or U-value is also reduced by spacers or lineals that utilize structural foam materials as part of the window frame construction process.
Consistent heat control to address ambient temperatures, viscosities and cure properties of a fast-bonding material or a two component (2K) sealant is a must for a consistent application. Graco equipment is designed and built to provide accurate, on-ratio mixing and a consistent flow rate of adhesive sealant materials to deliver superior sealing applications and provide highly structural thermal barriers.
