    Bonding a warm flat roof

    Thank you for the info. Regarding the Insofast, you'll see that I've started a separate thread trying to find out the difference between the two. Regarding the EDPM, I will indeed be having a 12mm external plywood on top of the TD4126. There is still a part of me that thinks I should...

    Warm Roof Insulation - I'm SO SO confused

    Question about 1:3:6 ratio mix concrete

    Thank you. It isn't going to be the finished floor. There will be a screed on top of it. The plans show that I need 100mm of ST2 which I believe is 1:3:6 I'm only going by what the plans state. Are the plans wrong???
