Frequently Asked Questions

What are aluminum spacer bars used for?

Aluminum spacer bars maintain the gap between glass panes in double or triple glazing units, provide structural support, and house desiccant to prevent condensation.

What is a warm edge spacer bar?

A warm edge spacer uses low-conductivity materials (like stainless steel and plastic) to reduce heat transfer at the edge of the glass, improving thermal efficiency.

Can I customize the color of the butyl sealant?

Yes, we offer customized color options for butyl sealants to match your design requirements.

Do you offer samples?

Yes, sample orders are available upon request. Contact us via the official website for details.
