He insulated the house S = 56 m2, took a polynor on the basis of 5 cm per 180 m2, did according to the instructions, in the construction industry for more than 15 years, was interested in seeing advertising, had doubts and a choice in insulation, did not want to bother, itching from ursa and overpaying for ppu hiring from the side, now I regret that I made my choice in the direction of polynor. The first is the price, the second is the declared output of the insulation, the third is a marriage (out of the total number of 17 cylinders that I purchased, they were not printed in the gun), and the remaining gas is still a third of the foam. Fourth, this is not a uniform distribution of warming (maybe the hands grow in the wrong place, but when expanding there are gaps and places where the layer is less than 2 cm.) The maximum layer is 3 cm. In one pass. per 1 m2 from the bottle.
Result: there is no declared layer, overpayment for insulation (for PPU I would give 100r / m2 with a 1cm layer, that is, for the money spent for 3 cm of polynor, I would insulate 4-5cm of PPU, or 10cm of extruded polystyrene (so as not to itching) or with a basalt stove + hire workers for warming. There is no benefit, but there is no talk about saving at all. The heater is very combustible !!!, It breaks down in the sun like mounting foam, as stated on the site about the closed cell structure is a lie! (this one-component composition. maxim 30%.)
Regarding 17 defective cylinders: I wrote a complaint to the store for the customers, for the exchange, where I purchased it on 08/16/2016, 2 weeks later they called back and said that they had sent the marriage to the factory for inspection, this is at least 2 more weeks, it remained to insulate the attic, a month of time lost, still it’s not a fact that a month, it may be necessary to decide through consumer goods, according to the law, a claim for 10 working days can then be brought to court and you can put 3% of the amount for each day on the meter. the current house will not be completed from this, and the cold will come soon. that’s your own conclusion.
Minuses
Price, declared consumption, invented characteristics, marriage from the factory.
