Q: What are the advantages of ordering insulating strips in coils?
Lower shipping costs because the need for heavy wooden boxes is eliminated.
Reduced inventory and part numbers because pieces can be cut to exact lengths. Since the coils can be up to 1500 feet long, only one part number is needed.
Easier material handling due to the fact that the coils are only between 30 and 50 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.
Q: What are the profile limitations of coils?
Although any profile can be provided in straight lengths, only flat and offset profiles can be packaged in coils.
Q: What geometries can be extruded in glass reinforced polyamide?
Simple to complex geometries can be extruded using glass reinforced polyamide. We have hundreds of shapes available in our standard product catalog or we can create a custom shape to meet your needs.
Q: If I have aluminum extrusions with a slightly different pocket design, can I use Technoform Bautec articles?
It may be possible depending on the pocket design. Please contact Technoform Bautec for advice on your specific application.
These questions are frequently asked by our customers.
Q: How do I know if the strength of my design is adequate?
The AAMA TIR-A8 technical report outlines the method for analyzing both mechanical crimp-in-place systems using glass-reinforced polyamide and chemical poured-in-place systems that utilize polyurethane. The report includes a software program for performing the analysis and is available at www.aamanet.org.
Q: Should I use insulating strips with glue wire?
Typically, glue wire 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 insulating strips with or without glue wire to fit your 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 insulating strips made from glass-reinforced polyamide?
- Glass reinforced polyamide expands and contracts at a samilar rate to aluminum so there is no differential shrinkage between materials
- Since glass-reinforced polyamide is an engineered plastic, it transfers longitudinal (dead load) and transverse (wind load) shear.
- Glass-reinforced polyamide will withstand higher temperatures (above 170°F) 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.
- Even the most complex geometries can be provided with extremely small tolerances
- The assembly process is efficient and clean.
- Multifunctional profiles can hold gaskets, foam, and or have fins that break up large cavities improving overall thermal performance.
Q: Why is a two insulating strip design better than a single hollow strip design?
Two strips provide two times more shear strength than a single hollow. What’s more, two strips crimped in place allow the assembly to act as one strong, tubular shape.
Q: Where can I get the equipment needed for assembly?
