# Will a push out window or half slide window cool down a room faster?

• questionboy
In summary, the type of window that will cool a room down faster depends on the direction of wind and the angle of the hinged window. The hinged window may be better or worse than the slide window in terms of aerodynamics. When there is no wind, the hinged window may not be significantly different from the slide opener. Comparing the two when slightly open is difficult and would require a numerical degree of openness and an optimum angle for the hinged window. The only fair comparison would be when both windows are shut and have equal draught-proofing properties.

If you have a push out window the whole area is open but much of the wind is blocked depending on the angle. With a slide window you often have half the open area but you can get direct wind over 180 degree angle.

Which one will cool the room down faster under which circumstance? If there is no wind will the push out window let more hot air out. If there is moderate to high wind will the slider let the wind bring down the temperature?

It all depends upon the direction of the wind and the angle of the hinged window. It could be better or it could be worse. Aerodynamics is a complicated business.
I guess that with no wind, a hinged window wouldn't be very different from a slide opener.

But how would you compare the two , if you're comparing their performance when only slightly open - what numerical degree of 'openness' would you assign to each one? What angle would you have the hinged window - the optimum, each time? The only time you could do a fair comparison would be when both are shut and you could then compare the draught-proofing properties (glazing area and spec being equal).

## 1. Will a push out window or half slide window make a significant difference in cooling down a room?

Yes, both push out and half slide windows can make a noticeable difference in cooling down a room. However, the effectiveness of either option will depend on various factors such as the size of the window, the outside temperature, and the insulation of the room.

## 2. Is one type of window better for cooling down a room than the other?

It depends on the specific situation. In general, push out windows tend to have a larger opening, allowing for more air to flow into the room. On the other hand, half slide windows can be opened partially, which can help control the amount of air entering the room.

## 3. Will opening both types of windows at the same time cool down a room faster?

Yes, opening both types of windows can create a cross breeze, which can help cool down a room faster. However, it is important to note that the effectiveness of this method may vary depending on the layout and design of the room.

## 4. Are there any other factors that can affect the cooling speed of a room with these windows?

Yes, factors such as the direction of the wind, the size and placement of furniture in the room, and the type of curtains or blinds on the windows can all impact the cooling speed of a room with push out or half slide windows.

## 5. Will installing these windows alone be enough to cool down a room?

No, windows alone cannot effectively cool down a room. They can help with ventilation and air circulation, but to significantly cool down a room, other factors such as insulation, air conditioning, and shading must also be considered.
