Four (4) Threshold Options

All folding door configurations are available with four (4) different thresholds; High Performance, Double Weather Seal, Low Threshold and Flat Bottom. With a step-up, the High Performance sill offers superior air, wind and water resistance. The Double Weather Seal balances good air, wind and water tightness with a decreased threshold and is well suited for renovation projects. A Low Threshold option offers a rise of only 11/16” with a partly recessed design. Finally the Flat Bottom design is intended for interior applications or areas with significant roof coverage, allowing for easy passage and maximum convenience in high traffic areas

Opening Configurations

SINGLE MAN DOOR FOR EASY PASSAGE. With 22 different opening configuration options to choose from, the perfect door is just awaiting your approval. Choose the number of door leaves based on the opening size and decide if you want them to open inward or outward. Assess whether you want them to open all on one side or split with doors panels on each side of the opening. Lastly, an optional door locking principle allows the first leaf to be used as an entrance door without affecting the folding capacity of the system.
