Fascinating Silicone™ Economics – Window Manufacturing

A silicone hot melt sealant allows fabricators to manufacture stronger and better-sealed windows in less time and at lower cost.

Hot melt silicone technology makes stronger windows ... FASTER!

As residential and commercial construction reaches record levels in many parts of the world, window and door manufacturers of all sizes are looking for new glazing technologies that will help them keep pace with demand.

A silicone hot melt sealant allows fabricators to manufacture stronger and better-sealed windows and doors, while reducing the time and cost associated with window and door manufacturing by as much as 33 percent.

Window glazing (affixing the window glass to the sash) is usually accomplished with adhesive tape or liquid sealants.

Using glazing tapes does not require expensive equipment, and adhesion is immediate, so windows can be quickly passed along to the next stage in the glazing process. But the quality and consistency of the application depends on the skill of the applicator, and time-consuming rework is sometimes required.

Liquid sealants can be applied with automated equipment and offer superior long-term sealing performance, but they can squeeze out when the glass is pressed into the frame, adding an extra cleanup step. More importantly, the windows are occasionally put on hold while the sealant cures, which takes added time and space.

Manufacturers who use the new hot melt silicone sealant get the best of both techniques – the immediate hold of a glazing tape combined with the superior quality and consistency of a wet sealant – without the squeeze-out and hold-time drawbacks. Windows can go from one processing step to the next without delays, and can be shipped as fast as they can be made.

These features reduce production time and the need for costly warehousing space while providing a uniform, continuous sealant barrier to the outside elements.
