Tawpna
Insulating glass unit-ah chuan secondary seal hi background material a ni lo-chu chu structural stability system a ni a, chu chuan long-term performance a tichiang a ni.
Silicone sealant hi a siam dik a, IGU siamnaah dik taka dah a nih chuan, tunlai architectural glazing atana pawimawh tak, elasticity, durability, leh weather resistance balance a pe a ni.
Procurement team leh IGU siamtute tan chuan key takeaway chu a awlsam hle:
Sealant i thlan mai mai a ni lo.
Glass unit siam chhuah apiang hun rei tak-reliability i thlang a ni.
A chhan chu IGU pakhatin factory a chhuahsan a, building façade a luh veleh a hlawhchham chu material issue a ni tawh lo-system-wide cost a lo ni ta a ni.
