Insulating cement roof and walls?

Question

Sun hits directly on roof and front and back walls leaving the inside of house very hot. Is there a fairly quick fix to insulate against these conditions

Answer 1

To insulate the roof and the walls from heat or from cold, the best way it to put fiberglass on them in the inside and cover it with "plaster plate".
But in fact it all depends on what you already have on your walls and roof. You should give us more details. Fiberglass would be the best way for me, that's what I put in my own house.

Answer 2

Without details regarding what's between the roof and the ceiling below it, no matter if it's a one story or two story structure; QUICK FIX might be relative?

If for example,,,and I have to assume this, that some insulation exists in an attic, crawl space, etc. then certainly that should be checked for an "R" rating, and decide to add or change. Perhaps the "venting" type fixtures often installed are either absent of not strictly functional. Perhaps old time methods like attic exhaust fans might be employed? What is the structure of your roof to the point where under roof vents, soffit and facia exist?

Without knowing the substance of the structure, IE: Block, Frame, etc., you might try to determine if in fact the walls are insulated, and attempt change in that also.

A more natural fix, but certainly not QUICK would be to have trees blocking and shading where the Sun does strike the house.

Windows in the path of the Sun can be tinted, as they provide no, real insulating properties. Awnings over windows on the exterior might help in small measure.

I live in Central FL. and happen to very much enjoy Sun and heat, but certainly it can cause economic budgetary issues.

There are numerous ways you can attempt to block the Sun, or insulate the house, and all may be valid, even in conjunction with the others, but Quick is, as I said, relative to how much effort and money you have to put into the effort.

Went back to CEMENT in the Original. Is the ROOF cement as well? Is this in fact a "house" or apartment building? Is the "cement" "POURED" concrete panel construction, or is it "block"?

Answer 3

Paint it white first, the brighter the better especially the roof. Painting roof shingles is a good idea because the paint wears off before the shingles do. a painted shingle roof will last for ever if kept painted . Exterior latex paint will do the trick although you can get latex roof paint. Block of sunlight from any windows with shutters on the outside. Once the sunlight goes through the glass and is inside the house you own the heat
If you can figure out a way to keep the sunlit area wet, the evaporation will really cool the house. The trick is to keep the area wet,not dripping,using as little water as necessary to keep damp. You can always spray it with a hose once in awhile

Answer 4

Insulation unfortunately, insulates to keep the inside warm... if you put the insulation on the inside. If you put the insulation on the outside, it will keep the heat out.... having said that, the insulation will be a huge mess when it rains for the first time unless you use styrofoam panels.

I suggest you make the air inside the house move around. Ceiling fans, portable fans, whatever. If you move the air below the concrete, it won't heat to the same degree or nearly as fast. Move the air and move the heat.... leave a non-sunny window open for a cool source for the air movement to grab from.

Answer 5

paint roof white,use liquid nails to put up styrofoam panels inside on walls,styrofoam ceiling tiles up, then glue paneling on walls over panels.

Answer 6

Paint them all white.

Answer 7

you can paint it white to reflect the sun
