STANDARD THRESHOLD
Our standard 55mm threshold provides a full weather break, helping to keep your home warm and dry no matter the conditions outside. It’s the recommended choice for all external bifolding door installations.

Our 20mm Low Threshold offers a sleek, seamless transition between spaces. While it provides less weather protection, it’s ideal for reducing trip hazards—making it a great option for families with small children or individuals with mobility needs.
