Hi All,
Installing Insulation boards
I have got the 6mm Deltaboards, so firstly I was going to sweep the floor clean, then clean the floor with a sponge, wait until it's dry then paint the entire area with heatflex, once dry I was then going to lay the boards in a brick fashion, I was going to use 15 25mm screws on 35mm washers per board at 300mm differences to fix the boards down, once fixed I was then going to use some special thermal tape to tape the joints, and put a light skim of tile adhesive over the joints as per 3-falls picture on page 2.
Are there any problems with my plan so far?
I understand that I need to leave a 5mm gap all around the edges for expansion/movement is that correct? and because I will be looking to put the SLC ontop, would it be wise to purchase and install the spongy foam spacers all around the room for this purpose? because I'm worried that when I pour the SLC out, especially around the bifold doors that it will just go into the tracks if I don't protect it...
