Refractory Windows' three breakthroughs in fire resistance

1. SS304 stainless steel fireproof strips have been added to the opening part;

2. Three "interpenetration fireproof expansion strips" card slots been added to the opening part;

3. Abandoned the traditional "fire grouting" process. The "nano fireproof sticks" are used for filling. Enhanced thermal insulation and reduced sash deadweight;

The application of these three technologies, together with corresponding fireproof materials and measures, which effectively guarantees the national standard of Fireproof > 1 hour for "G72 refractory window".
