I'm doing a project on insulation, and I need to research one aspect of insulation (e.gwall/roof insulation)If you know anything, or if you can link me to a useful site, that would be great!
Your insulation is only as good as the care giving in installing itFiber glass is the middle child cost wise, but it is the one that gets installed wrong most oftenIf you have it installed or do it yourself, make sure that you follow installation rules or you are loosing effenciency on your utility billsOwens corning makes a good product, but try to get the type without the formaldehydeI know that Lowes sells the white, James Mansfield brand which is this typeI like it because it does not make me itchLess odor as wellBlown in insulation is the cheapest to install and also the messiest when you have a repairIf it gets wet or if you have unwanted furry guest,( it will become perfect litter and bedding for them ) it can be ruined or loose its r value quicklySpray foam will cost you more but it will save you more heating and cooling cost in the long runI remodeled a garage aptIt would have been 1100 for regular fiber glass and it cost almost 2000 for the spray foamSo almost double, but it was a small job, only 500 Square feet of floor spaceMy guy charged me 1.25 a sq ft for 2 x 4 walls and 1.75 a sq ft for 2 x 6 roofthese seemed to be good base line pricesMy average electric bill is 36 to 50 dollars for this unit now where before it ran as high as 135 dollars for coolingSo I made up the difference in cost in less than 18 monthsI recommend going with the spray foam, no bugs get in, no mold in the walls where you can not see it, water pipes are insulatedIt also keeps the noise level downCousin can play his music pretty loud without disturbing the neighborsLuck to youChris
best advice, go with a guy who will come in and do a spray foam insulationyou can do it yourself, but it's not recommendedit gives i belive an r30 value and is fire retardant if you don't want to pay for a spray foam guy: there is an insolation that is made of recyled blue jeansit's an r20 valuethe pink panther stuff will workbut it's not the best and you loose some heat out the wallsit will work and it's cheep hope this helps
R-16 insulation is what they normally use in construction you can double up on it also if needed to
wall insulation: Installing wall insulation requires a little forward planning as it can only be installed prior to the wall linings being applied, i.eat the time of construction, re cladding or re plasteringHowever, it is well worth the effort, as insulating external walls will save you approximately 15% on heating and cooling costsYou can also utilize wall batts in internal walls to help control and reduce the level of noise in your home to give you that added bit of peace and quiet-Materials: stable glass fibers bonded with thermo setting resinsLight in weight, strong and resilientEasy to handle.
