I have built a new home. 2″ extruded under slab right up to the eaves. Hydronic in the slab and 6 future runs. Over sized the boiler. Wife is now cold on main floor due to cathedral ceilings. Am considering gypcrete on main floor before finish work is completed. QUESTION?? Is gypcrete the only “surfacing” solution to crete mass and embed water pipes? Will look at tile in kitchen, halls and bathroom with separate zones for each room, kids rooms in carpet. Installation procedures, installation tips and specifications for this product welcome so I can control the job. Thanks…..Kayne in Edmonton Alberta, Canada
