doug,
im looking to talk to alltec about their heating system, as i know they are interested in the mats aswell.
the dessicants are good casue they create a grreat dry atmosphere, above the mat, and then the mat targets the air.
weve been using polythene but sometimes u get a failure, and i dont like that.
i'll email u a pic if you wish ?
for us the mats adds another tool to our range of services, and if we can get an in with a couple of the loss adjusters that we work for then i will be a happy chappy.
at the moment looks as if we have enough drying work throu till february, and then options on the reinstatement, so all looks good.
the only time we use refigerants now, is on the self pump out units to condense the moisture, if we havent got a convenient external venting point.
regards
martin
