We can avoid heat waves indoors, especially in air-conditioned rooms, but is the sealing effect of your door sweep installation inside or outside really enough? Can it really block the heat waves from entering outdoors?

Aoqun teaches you how to choose a door sweep installation inside or outside with good sealing effect to block heat waves and enjoy a comfortable environment:

1. Choose a brush that is dense and uniform in thickness, with a moderate opening angle, no cross filaments (local cross skew), no light leakage, and no obvious gaps in the filament.

2. Select a brush that does not deform. It will not roll or fork during the long-term opening and closing friction process to ensure the air tightness and integrity of the door brush. Aoqun door sweep installation inside or outside will not deform after 1 million times of high-speed friction.

3. Choose a brush with neat filaments, no leakage at the top of the peak, no unevenness, and different lengths, which can prevent the airflow from flowing into or out of the "gap" of the door sweep installation inside or outside. Aoqun helps customers save 36,000 kWh of electricity every year.

A door sweep installation inside or outside with the above characteristics is a good sealing effect, and it is the door sweep that you need to perfectly block heat waves and cold currents in the hot summer and cold.
