FAQ

I added a screened room to my mobile home. I also have vinyl windows. in the summer the sun beats down on the home almost all day Someone told me I could have insulation installed in the roof panels, and that i may even be able to do it myself. Right now it's impossible to enjoy my patio between 1-5pm because it so hot you can't breath. I'm in the Pasco, FL area - 34667Appreciate any help you can give

Yes. Usually the insulation goes on the topside. You will need to measure the panels (mine are 4 feet wide). I also added a 6 inch valance at the end that acts as a gutter. Works great! Port St. Lucie area, neighbor.

Our roof tile is installed on top of galvanized iron sheets. We do not have any toher form of insulation. The roof tile or tegula is quite thick.

Absolutely. You will find in the summer that your tiles will heat up from the sun and will stay hot even after dark (the steel sheets don't exactly help either). Your energy bills will go down about 60% in the summer and 20% in the winter by just installing a cheap fiberglass filling. A good example of how these tiles are effecting you house would be a stoneware cup. Pour hot water into it and place it in the microwave until it boils. Feel that the side are very hot, too hot to hold (this represents the sun heating up the tiles). Now pour out that cup and fill it with cold water (which would represent AC in your home). In about 2 or three minutes, place your finger in the stoneware cup. The water will be warm. The tiles do the same thing. The absorb and distribute heat into your home during the warm months, and will rob your home of it's heat during the winter and cool months. Just by placing insulation in your home, you stop that unwanted heat exchange with your home and the outside world.

What is the difference between roof and loft insulations?

Potentially that the roof itself is insulated on the underside. A loft insulation could be that the base or floor of the loft/ attic is insulated. Otherwise, I'm not sure.

I know you're not supposed to directly insulate the roof due to the roof getting super heated in the summer, but my walk-in (actually, more like "crawl in") attic is very hot in the summer and very cold in the winter. Is there anything I can do to improve efficiency? I can't help but think I'm wasting a lot of energy just to keep my roof lasting a little longer.

You can avoid the condensation problem by simply leaving a minimum 2'' gap between the roof and the insulation. You need to fix battens on to the rafters ( at least 2'' from the tiles ) and then fix blanket or rigid insulation tight between them. The battens will maintain the air space. You then need to fix a vapour barrier over the whole thing and finish with plasterboard. No small job to do it properly ! ps you need to check the condition of the roof before you start and fix any loose tiles etc Alternatively, turn the heating up and wear a thicker sweater.

I am really confused about this science stuff! Sustainability is terrible xP

i'm designing a house it quite is a retangle on the 1st floor with an L shape on the 2d and installation into that L i choose to have a greenhouse related. My plan is to apply 2x10 or 2x12s for my floor joist that way i can insulate the ceiling of the room it is under that and the two partitions that are related to the greenhouse. no longer a lot to learn any warmth from it,yet to have plant life. If i choose to get any image voltaic benefit illl in simple terms open the door to the domicile

I do not have extra space on the roof. Roof also tapers to drains at one end of building.

the R values, i am not sure. that white stuff is NOT Styrofoam. it is a cheap imitation. Real Styrofoam is made by DuPont, is usually a light blue, with a plastic seal coat on both sides. that thin plastic seal coat doubles the R value. what really does the insulation, is trapped air. air is actually a poor conductor of heat. the foam is actually little bubbles of air. dead air that is, air that cannot circulate and move. it works similarly to the way a down vest or coat works, it fluffs up and holds the air pockets out within a confining structure, thus retaining heat. the rigid stuff will last much longer, i can tell you that much. the white foam stuff deteriorates quickly. buy cheap, get cheap, is the general rule. you may wind up only having to do it again in a few years.

Best roofing insulation to keep warm in the winter?

The best insulation that you will find is R15 fiberglass that is installed inside the attic between the roofing rafters. It's twice as thick as R12 which goes behind wall paneling. If you're talking about roofing shingles, they don't really act as insulation but architect shingles last the longest.

please help..

Both fiberglass and asphalt products are harmful to your health. Stick to brands like Raamat, Secondskin, and Dynamat.
