Hi – I will hopefully be moving shortly to a 1960s house that will inevitably require some improvements. I was wondering if anyone had any data/insight on pipe lagging, and which types were best.
As an example at a major DIY catalogue (rhymes with dew-bricks) there are:
economy polyethylene foam – 13mm thick
premium poly foam – 25mm think
spiral wrap foil – claims to be equiv to 33mm polystyrene
My thinking was to use one of the foam types and then wrap in the foil wrap. Is this a viable method or do the foils have to be next to the pipe to reflect the radiant energy straight back.
Are there any other interesting methods/products that people have used? (e.g. is it worth using any spare bubble wrap from packaging to increase lagging of pipes outside the foam products?)
Thanks in advance,
Adrian
