Common questions

Are these certified for IECC compliance?
Yes on the certified configurations. NFRC ratings cover IECC energy code in every US state that adopts it. CSA A440-22 #80224506 is on file for cold-climate zones 5-8.
Can I get Energy Star eligibility?
The bifold configuration is US Energy Star registered (FXC-M-3, valid through 2029-07-20). Energy Star eligibility on the rest of the line depends on climate zone and configuration; we confirm at quote.
What about HVHZ jurisdictions?
The hurricane impact line covers Florida HVHZ counties. See coastal Florida for the dedicated HVHZ posture.
What lead time on a new-construction order?
Lead time on a configured order is in the 13 to 18 week range from purchase order to delivery. Pricing is locked from PO to delivery in writing, which matters on long build cycles where dealer-supplied product can re-price mid-project.
