Hi All, I have been recommended, anecdotally, that UFH pipes laid in a biscuit screed / pug mix for my 1st floor (suspended) will be 'better' than aluminium spreader plates, however, and as an engineer, I'm much more comfortable when talking about numbers... I'm struggling to find heat output data for UFH pipes laid in a biscuit screed / pug mix. The only source I have found is a datasheet on Continal's website, but the variables are fixed at 55-60C flow temperature and 1tog of insulation above. Has anyone come across a data table (or calculator) that shows other heat outputs for between-joist pug mix for different variables? - I'm interested, particularly, in heat output values for 35C flow temperature with 1.5tog (which I believe is approximately equivalent to 15mm pine floorboards). Many thanks, Oz

Hi jamieled, Who did you go to for the airtight door and frame? Have you got any sketches / photos you could share? Many thanks, Oz
