I prefer to cleanse my body th natural wayS I need foods that are high in fibers.
That the attic gets hot on a sunny summer day is to be expectedNo matter how good the insulation, it just slows the heat transferit can't stop itJust ventilate that attic in the summer months, and possibly re-balance the air flow on your AC system(Get a 'Pro, - not a DIY thing.)
more insulation won't helpyou need to get the hot air out of the atticyou need to install an attic fandownstairs is always going to be cooler,heat risesyour ac is not going to cool your atticyou need to ventilate your attic space.
you have to understand the r-value is from the insulation down and not up, If your insulating the rafter areas , then you have a air balance problem , not enough btu's for you air space look into your unit for its coverage.
First of all a 3° differential between upstairs and downstairs isn't badThat is as long as you only have one a/c unitIf you have separate units for the two locations then it isn't so great 12° differential from outside to the attic isn't bad enough to worry a lot about ventilation in the atticAn R-value of 30 IF in fact it is that high is respectable and adding to it won't make a huge difference If you have one a/c unit try closing some vents downstairs and make sure all vents are open upstairsMake sure blinds are closed upstairsIf you have two a/c units it is possible the upstairs unit is undersized or needs service.
