Uji Hujan Penghalang Uap NF30 | Tidak Ada Membran Luar Ruangan — Masih Kering?

Kategori: Kaset Jendela

Apa yang terjadi jika lapisan kedap air eksterior gagal? Kami melepas membran luar dan menguji NF30 saja. Jendela, sambungan, dinding — terkena hujan lebat selama 24+ jam. Sisi dalam ruangan: benar-benar kering. Nol kebocoran. Penghalang uap dalam ruangan NF30 menghasilkan kedap air yang andal — dengan atau tanpa cadangan luar ruangan. Pabrik langsung dari Zhuheng.
