Problems solved by technology

When the ambient humidity is high, especially during the rainy season in the south, the wall will often appear "water hanging" phenomenon; when the wall insulation is not done well, resulting in a large temperature difference between indoor and outdoor, the water in the indoor air will be Condensation on the wall will cause the wall to be damp; the wall will be prone to mildew if it is wet for a long time
