Both are the same thickness of 80 mm wide, (aluminum wood is 6 +2 cm, 6cm wood 2cm aluminum; broken bridge aluminum thickness of the whole 8cm) compared to the insulation effect is definitely a good combination of aluminum and wood, then the noise The
Plastic insulation effect is better than other profiles, the price is more expensive.
Aluminum and broken bridge is just the window frame, sound insulation or depends on the soundproof glass, and sealed Kazakhstan. It is better to seal the plastic
Because the sound of metal is stronger than non-metallic, steel is non-metallic. In addition, the aluminum alloy, broken bridge production process to the combination of stitching, and the hardness and gap larger, the overall sealing is not strong, affecting the sound insulation effect, steel production is about 260 degrees high temperature hot melt welding, air tightness Better, and steel frame multi-cavity structure, sound insulation is more superior.
Sound insulation windows with aluminum and broken bridge just look higher grade, the price is also more expensive.
