    Default Small or large bubbles for bubblewrap insulation

    I need to spot paint my masts whilst they are down, but the minimum temperature needs to be 15c. I am proposing building a heated moveable tent which I can slide along the mast as I paint it. The tent is really a small structure made of gash wood and I thought to maximise insulation, this could be covered in bubble wrap. I did not appreciate there were 2 sizes of bubbles in bubble wrap - big and small. My question is, should I go for the small bubbles or large bubbles to maximise insulation?

    The bigger the gap in double glazed windows the better. So looking at bubble-wrap as DG insulation, go for the bigger bubble.

    Surely min temp means for drying not just application, as soon as you move the tent the area will cool down,

    try to estimate the "double bubble" area. Looking as a bit of large bubble stuff here, my guess is that somewhat less than 50% of the area is actually bubble. The rest is single skin poly and that will not insulate very much at all.
    If I show you yours, will you show me mine?

    you can get foil bubble wrap used for insulating roofs, it comes on a roll 900mm wide, from B&Q etc

    If the tent is "really" small, you will probably only be raising the ambient temperature of the air inside the tent. The temperature of the mast itself (even the portion inside the tent) will probably remain cold, inhibiting the proper application and curing process.

    So he should pipe warm air through the mast while the paint is curing.
