The opening movement is a useful starting point when comparing glass doors. Look at the room with the doors open and closed, then consider the view, furniture, everyday access and the space available outside.
Sliding and lift-and-slide doors
Sliding panels travel sideways along tracks. A lift-and-slide system uses a lifting action before the panel slides. The arrangement of moving and fixed panels determines the opening that is available; ask to see the proposed configuration on a drawing.
Compare where the panels sit when open, how the handle operates and the route through the opening. See our sliding doors and windows page for the GlasSpace approach.
Folding doors
Folding doors have connected panels that fold together as they open. Their parked position needs space beside the opening. Check the proposed opening direction and how the folded panels relate to chairs, planting and walkways.
Hinged doors and French doors
A hinged door swings from one side. French doors use a pair of opening leaves. Draw the swing of each leaf on the room plan rather than judging the arrangement only from a front elevation.
Pivot doors
A pivot door rotates around a pivot axis rather than conventional side hinges. Its movement can occupy space on both sides of the opening. Ask the supplier to show the swing and usable passage width for the particular design.
Appearance and performance are separate questions
Frame width and panel divisions influence the view. They do not, on their own, tell you how a complete door system will perform. Compare the specification of the actual proposal, including glazing, weather performance, security, thresholds and maintenance.
Bring your priorities to a conversation with GlasSpace: which door will you use most often, where will furniture go, and what should the room feel like when everything is closed? These questions help turn a preferred appearance into a practical brief.
