    haha good point Grant - when you put it that way... it's also not more than something like an upright piano which I wouldn't worry about putting in there, I suppose.

    Macca I calc the weight per box as more like 15-22kg. 100 LPs at 150gm each... 100x150= 15,000gms or 15kgs.
    150 LPs per box would be approx 22kgs.

    22 Kgs full i.e weight of box and LPs? Then your fine as 3 of them in a square metre is only 66 kilo. If my maths was right.

    Grant has a point as in two big blokes stood in the same square metre could easily collapse the floor if it could only take 150KG.


    With the WW2 Tiger Tank the way to determine if the ground ahead could take it was for one crewman to get on the back of another and then he had to stand on one leg. If he didn't sink in then the ground was firm enough to take the vehicle. I don't think they compensated the crews for any resulting spinal injuries but then they had better things to worry about I suppose.

    Andy: I'm pretty hopeless at maths but the dimensions of the record storage unit are 48cm x 33cm and the footprint will be 4 of them in a row. Total weight estimated 225kg.

    I calculate the footprint to be 0.63m2. 225 divided by 0.63 gives a result of 357.1kg/m2 or more than double the modern spec! Or have I made an error in my maths? (quite possible)
    Based on Andy's data "Domestic properties are designed for 1.5kN/m2 which works out to be 153kg/m2.

    So work out the total weight of your lps and divide that number by the area the boxes occupy as a footprint plan on the floor and provided it does not exceed 153 then you need not worry."

    A box 48cm by 33cm should hold about 100 records each record will weigh about 200gm (vinyl & sleeve) so 5 records will be 1kg, therefore 100 records on one of your boxes will be 20kg.

    The floor area that each box takes up is 0.48m *0.33m which is 0.1584m2. So 6.31313131 boxes fit in a 1.0m2 of floor space, so the weight on the records occupying 1.0m2 will be around 6.313131 * 20kg = 126.262626kg. You need to add on the weight of 6 boxes.

    So if my calculations are correct and your joists/floor meet Andy's specifications you have around 25kg spare (some will be used up by the storage box weight), bear in mind some records may be 180gm vinyl, if you have lots of old 78's then they will be heavier.

    I think I have this correct, if not shout someone.

    fatties better not kiss in the upstairs of house or the earth will move only other thing to watch is that the floor wasnt originally a loft as joists are often not as thick. but they should have been replaced or strengthened if it had been

This is the supreme test. It is the glory of Lincoln that, having almost absolute power, he never abused it, except on the side of mercy".

They are afraid of words and thoughts: words spoken abroad, thoughts stirring at home -- all the more powerful because forbidden -- terrify them. A little mouse of thought appears in the room, and even the mightiest potentates are thrown into panic.”

    Loft joists are like matchsticks in my (1901) house. I daren't put anything up there.

    You might find this helpful https://www.ehow.co.uk/how_7485788_c...-capacity.html or get and engineer to work it out>. If the joists are less than 8 by 2 timbers then you definitely need to get it worked out to be safe, IMO.

    OK well I had a loose floorboard up to take a look underneath - the joists look pretty solid to me, they are 3x9 inches more or less I would say, and heavy timber. They run across the room at right angles to the proposed shelves, which would therefore be supported over several joists.

    They look exactly the same as the joists in the 1st floor bedroom floors, so not loft joists I would think.
