Stair Layouts
JELD-WEN manufactures all staircases to order in almost any
design, size or specification. However, to help plan your flight, our
20 most popular layouts are listed on the following pages together
with the critical dimensions relevant to each design including the
trimming dimension necessary to obtain headroom clearance.
Our specialist stairs team is always on hand to offer help and
advice on any aspect of design, construction or Part ‘K’ of the
Building Regulations. You can contact them on 01664 484613
