I have a 1995 Ford ExplorerI keep getting two different answers from the webSome say it uses R12, which they don't sell anymore, others say it uses R134a which you can buy and recharge yourselfIf it's R134a, I would like to know where the spot is to refill it if anyone knows, but I really just need to know which type of Freon it uses.
If you have clear access to your rafters, the best insulation possible (after installing your vent baffles) is sprayed on foamI didn't say polyurethane foam on purpose, as there is now a soy based foam available with exactly the same working and thermal characteristics as the petro-poly goop, with none of crude oilBut i digressSprayed on foam has the advantage of not only thermal insulation but it also seals everything that it comes in contact with, thus stopping any air movement, something that no fiberglass or extruded polyurethane could ever doIndustry experts are still debating this but, it looks like 1 inch of sprayed on foam (with it sealing qualities) does as much, if not more, than 3 1/2 inches of fiberglass and, foam will never sag or absorb moisture like glass doesFill your rafter spaces and gloat to the neighbors when your bills come in:)
The new metal roofs offer both the durability and the insulationMetal roofs come in many shades and are made to reflect the heat away from the houseThe insulation in these roofs are often the highest R factor.
It uses 134A and the valves have round plastic caps on them and they are usually located on the aluminum discharge and suction lines coming out of and into the compressor.
No matter what material you use for the actual roofing, make sure you have a Radiant Barrier installed at the same timeThere are several different ways this can be achieved, your roofing contractor can (and should) advise you on the best method for your home.
I am going to convert my loft, so was researching this subject as wellI once saw on TV (I think on Renovation program) how they make insulation from sredded paper - this was a very inexpensive and very efficient way of doing itAlso they said that the best insulation is the one made from sheeps' woolYou can buy this from major DIY storesHave a look at the links below
