Calculating how many floor slabs for insualtion.

tcooley · 27-10-2021 1:17pm #1

Hi all, wondering can you help me here.

We are putting down the floor slabs soon (2 x 75mm slabs). I see I have to measure the perimeter area ratio? How would I do that? I haven't a clue. Is there any online calculator I can use to see how many full slabs I need?

Example: My front room is 4900 x 4500cm so would that be roughly 5 or 6 sheets?

Thanks,

You posted this earlier. How many threads do you need?

I put it in wrong section. My apologies.

Simple.

Multiply length by width.

Multiply slab length by width ( normally 2.4 m X 1.2 m = 2.88 sq m).

Divide floor area by 2.88 sq m and there's your answer.

"Divide floor area by 2.88 sq m and there's your answer."

there's half your answer.

In your example you would need 8 sheets for a single course or 16 for the two.

you might get away with 15 sheets.
