Typically, glue coil is used only when profiles are powder coated after assembly. Tests have shown that some shear strength is lost when non-glue coil profiles are exposed to extreme heat during the baking of powder paint (360® - 390®F). That's why we provide Thermal Strips with or without glue coil to fit the manufacturers needs.
Q | Is the bond between polyamide and the aluminum water-tight?
Yes. As long as the three-step assembly process is properly followed, the bond will be water-tight. Please remember that glue coil is not required to provide a water-tight joint when profiles are properly assembled.
Q | What are the advantages of using thermal strips made from glass-reinforced polyamide?
- Glass reinforced polyamide expands and contracts at the same rate as aluminum so there is no differential shrinkage between materials
- Since glass-reinforced polyamide is an engineered plastic, it transfers longitudinal (deadload) and transverse (windload) shear.
- Glass-reinforced polyamide will withstand higher temperatures that cause many thermal plastics to lose strength in the field.
- Glass-reinforced polyamide is resistant to the vast array of chemicals typically used in the production and cleaning process.
- With a track record going back nearly 30 years, glass-reinforced polyamide is the most proven material used for thermal break throughout the world.
Two thermal strips provide two times more shear strength than a single hollow. What's more, two thermal strips crimped in place allow the assembly to act as one strong, tubular shape.
Q | Where can I get the equipment needed for assembly?There are several thermal break assembly equipment manufacturers. Click here to see the list.
Q | What are the advantages of ordering insulating struts in coils rather than straights?- Lower shipping costs because the need for heavy wooden boxes or steel stillages is eliminated. Plus, there are no containers to return.
- Reduced inventory and part numbers because pieces can be cut to exact lengths. Since the coils can be up to 500 meters long, only one part number is needed.
- Easier material handling due to the fact that the coils are only about 30 lbs. This means one person can handle a coil versus the two people needed to handle straight lengths that can exceed 20 feet.
- Less waste is produced since the coils can be cut to precise lengths.
Although any profile can be provided in straight lengths, only flat and offset profiles can be packaged in coils.
Q | If I have aluminum extrusions with a slightly different pocket design, can I use Technoform articles?It depends on the pocket design. Please contact Technoform for advice on your specific application.
