Base & Structure
A conservatory base is the foundation, dwarf wall and insulated floor build-up that carries the frames and separates the room from the ground.
Conservatory foundations are normally trench-fill concrete dug to a minimum depth of 600mm, and deeper where trees, made ground or drains are present.
Clay soils and mature trees in older Glasgow suburbs frequently push the depth beyond one metre.
A conservatory floor should be insulated with a minimum of 100mm rigid insulation, because an uninsulated slab loses heat continuously to the ground.
Drains within the footprint must be diverted or fitted with an approved access chamber before the base is poured.
