Sliding garden doors contain one or more panels that move sideways. The proportion of fixed and moving panels determines the clear opening. Overall frame width is therefore different from the access available in everyday use.
How this term relates to your project
Compare configurations by operation, usable access and the connection between internal floor and terrace. Identify moving sections and their direction. Include furniture, curtains and shading in the selection. Threshold detailing must coordinate levels and drainage; a photograph of an apparently level transition provides little technical information.
Specify glazing, profiles, colour and surrounding finishes in the quotation. When reviewing performance data, establish whether it describes the complete selected assembly. Maintenance information and access to moving components also belong in the choice, rather than considering only the appearance of the doors when closed or their largest advertised external dimension.
