Why anywhere but Siberia is better not to three-chamber window?
IN recently become popular three-chamber windows. Who does not know the three glass in the cavity between which pumped an inert gas (argon), which does not give them promorznut.
BUT that's a big a difference between triple and double glazing
(Except for the price, of course)?
Do not be fooled and do not build illusions.
Nuance one: on the brochures you will see that the three-chambered package warmer dual chamber at 50%. But the small print will be assigned.
◘ Only at a temperature below -43 ° C.
◘ At a temperature of -36 ° C warmer than the three-chambered only 25%.
◘ At a temperature of -30 ° C warmer than it is only 12%.
And at - 25 ° C difference between the three and two cameras no. Going further ↓ ↓ ↓ ↓ ↓ ↓ ↓ ↓
Nuance two: which region you buy window?
If you live in Siberia and the Far EastWhere winter temperatures drop to -40 ° C and below, the three-chamber window - your salvation. Quite simply, in the winter the temperature reaches that threshold, when three cameras have a meaning.
If you are from The central part of Russia, from the North-West and especially from southern Russia (Hello, Kuban!), The two-chamber windows will be enough "for the eyes." Below -30 is almost never in the center of Russia (not that as a child, right?).
No sense to overpay easy.
