Why my hall is so hot?

Shahir Ahmed | Posted in General Questions on

My house is double floor house.. our 2nd floor hall is soo hot but other rooms are quite cool.. the length of the hall is kind of less to rooftop
The sunlight hit the rooftop n makes our hall soo hot than outside temperature.
Is there any way tu cool down the hall without any reconstruction?

    Shahir,
    I'm not sure if you are talking about a hall (corridor) or the room in the photo, which looks like a living room to me.

    In any case, the usual way to slow down heat loss from a hot attic (or roof) to the interior of the home is with insulation.

    I'm not sure what you mean by your hope of solving the problem "without any reconstruction." Here are three possible ways to to improve the insulation of your ceiling:

    1. If there is an attic above the ceiling, you can add insulation (for example, cellulose insulation) to the attic floor.

    2. If you have no access to the space above the ceiling, you could add a layer of rigid foam insulation to the interior side of the ceiling, followed by new gypsum drywall.

    3. If you can afford the work, you can add one or more layers of thick rigid foam insulation above your roof sheathing, followed by a layer of plywood or OSB roof sheathing, and new roofing. This approach isn't cheap.

    Shahir,
    One other point: It's possible that this room already has adequate insulation, and that the cause of the high temperatures is solar heat gain through windows. In that case, some type of exterior shading device might help.

    It's also possible that there is a problem with your air conditioner, or a problem with the ducts that deliver cool air from your air handler to the room in the photo.
