1. Generally, there are two kinds of kitchen windows: casement window and sliding window. Sliding windows are more suitable for kitchen windows, especially larger windows. The sliding window does not occupy space, and many things can be placed in front of the window, which will not affect the use of the countertop in front of the window. 2. The advantage of the casement window outward is that it will not affect the use of the faucet in the sink. If the casement window opens inward, it will hit the faucet and affect the use of the countertop inside. If the kitchen sink is installed in front of the window sill, pay attention to the position of the faucet when making the casement window. 3. The kitchen window should be decided according to the layout design of the kitchen cabinet. If the window is large, try to use a sliding window. A good way is to push and pull the window up and down. 4. If the window is relatively small and it is necessary to use a casement window, just open it outwards. If the floor is not high, you can install a guardrail outside to prevent the window from falling and hitting people and cars. 5. If there is a pool in front of the window sill, consider the height of the faucet. It should be noted that if the window opens to the left, the faucet should be installed on the right, avoiding the window sash. On the contrary, if the faucet is on the left, the sash should be turned to the right. You can also make a dead window at the bottom to avoid the faucet.
