How to distinguish bridge cutting-off aluminium windows?

The raw materials between bridge cutting-off aluminium windows and non-bridge cutting-off aluminium window applied are the same profile, both use aluminium alloy profile with excellent sound isolation. The inspection result shows sound isolation effect between both windows could reach 80%, which means indoor noise could be reduced to 35DB if outdoor reaches 90DB when tightly close the window.

The so-called bridge cutting-off aluminium windows means aluminium profile on both sides with nylon heat isolated strip between profiles, which seems like bridge over the river, the function of heat resistant strip is to prevent heat from house and keep home warm. Non bridge cutting-off aluminium windows are featured by aluminium alloy profile without cutoffs, metal profile is of strong heat transmission, so its warm keeping and safety is less than bridge cutting-off aluminium windows, hence the price of bridge cutting-off aluminium windows is higher than non bridge cutting-off aluminium windows.

Bridge cutting-off aluminium windows are charactered by good air &water impermeability, excellent heat keeping performance, it also adopts double hollow glass and helps save heating and cooling charges to extently achieve energy saving feature.
