ply

PLY is a computer file format known as the Polygon File Format or the Stanford Triangle Format. It was principally designed to store three-dimensional data from 3D scanners. The data storage format supports a relatively simple description of a single object as a list of nominally flat polygons. A variety of properties can be stored, including color and transparency, surface normals, texture coordinates and data confidence values. The format permits one to have different properties for the front and back of a polygon.
There are two versions of the file format, one in ASCII, the other in binary.

    Ufh And Ply

    So, i have a conservatory to tile with 200 x900 porc with wet ufh and 22mm ply on top. The ply is deflection free but i don't like tiling on it. Would ideally backer board it but worried about insulation properties. So, the plan is ditra. Is this the route you guys would go? cheers

    Ply Vs Osb

    Bin doin some reading after speaking to a builder I do some work for and it's got me thinking has anyone got any info on osb being used for overboard floors to fit ditra to as osb comes in tongue and groove so in theory the joints are much stronger than a ply join ?
