Wind Resistance

STP cares about all the details and structures, that’s how we created the most carefree aluminum windows user experience for you.
Reverse S-hook design, with thick and deep hook groove, this design makes the sashes have great stability, allows the window frames move with wind pressure in synchronization. The thick mid handlebar, strong and tough structure, increases wind resistance. As for the small air inlet created by synchronized wind pressure movement, will be protected by two-wings gaskets, prevent wind pressure from invasion and undermine the window structure.

Heedful deep glass ditch design
By the special deep glass ditch design, increase the glass inflection that window frame can take, make sure the glass maintain stable with frames even under heavy winds, greatly increase wind resistance.
