FAQ
Folding Windows Frequently Asked Questions
Essential guidance for commercial contractors, architects, and importers selecting factory-direct custom aluminium folding windows.
What opening styles are available for KARON aluminium folding windows?
We manufacture multi-panel side-folding bi-fold windows (folding to left, right, or both sides) and vertical up-folding windows (gas-strut motorized or manual flip-up counter windows) in thermal break and non-thermal break profiles.
What thermal break insulation technology do you use?
Our thermal break folding window profiles incorporate high-density Polyamide PA66 insulation strips. Combined with double or triple Low-E argon-filled glass, they effectively block heat transmission and minimize cooling energy consumption.
Can folding windows be produced according to custom architectural drawings?
Yes. Every order placed with Karon Window & Door Co., Ltd. is custom engineered based on your project schedule, CAD drawings, wind pressure ratings, glass specifications, and surface powder coat colors.
How do you ensure weatherproofing and water resistance on large openings?
Our systems use continuous EPDM sealing gaskets, interlocking sash profiles, concealed drainage channels, and heavy-duty compression locks to maintain air and water tightness under severe storm conditions.
