Choose the roof, the wall or the floor and enter its dimensions (openings are deducted for a wall). PRAXAO works out the area to insulate, the number of panels to buy with the waste, the volume of insulation, the fixings, the adhesive for a wall and the vapour barrier with its overlaps. Panel size, thickness, fixings, adhesive, overlap and waste are starting values to replace with the maker’s data. The tool counts quantities: it does not give a thermal resistance or a U-value.
Choose the type of work, then enter the dimensions.

Area to insulate: 27.60 m² · Panels to buy: 42 · Area covered by the panels: 30.24 m² · Insulation volume: 1.380 m³ · Fixings: 166 · Adhesive: 110.40 kg · Vapour barrier, with overlaps: 30.36 m²
The tool does not choose it. The thickness a project needs depends on the climate, the construction and the regulations: it comes from a thermal study and the maker’s data.
The area to insulate is increased by the waste, divided by the area of one panel and rounded up to a whole panel.
No. Whether one is needed, and on which side, depends on the construction and the climate. Untick the option when it is not part of your build-up.
Area, panels with waste, fixings, adhesive and vapour barrier: the method to order thermal insulation, with an example.
Slope area, tiles or sheets, battens, purlins, rafters and ridge of a gable or hip roof, from the building size and the pitch.
Plasterboard sheets, studs, track, furring channels and screws for a partition wall or a suspended ceiling.
Plasterboard or lay-in tiles, furring or grid, hangers, screws and jointing compound of a suspended ceiling, from the room size.
