2 years back I bought a trek 1200 bike at a garage sale and I would like to know the year and price?

Trek1200 aluminum (trek 6061t6 heat treated alcoa aluminum) (CR-MO Chrome molybdenum fork tubing) (shimano 105)


it is discouragedcompressing insulation lowers its effectivenessit is meant to stay fluffy with the air around ityou can buy a higher R-value in the same thickness thoughspray foam insulation is best, but expensiveblown in cellulose is next bestlastly fiberglass batsa bat is what they call one piece of roll insulation.
Sounds a lot like my old TrekIt was a black 1200 aluminum with 105 components I bought it 2 years old in 90 for $300At that time they were selling new for about $600In 88 and 89 they were equipped with 105 components1988 it came in Black and in Blue1989 it was available in Black and in WhiteThe 1987 model came with Sun Tour components and in 1990 they switched to RXSo in summary: 88-89, retail $600 new.
In hollow wall construction the insulation is provided by airThat's about as good an insulator as you can get unless you use a vacuum (impractical)However, there will be convection currents in the air gap that conduct heat acrossThe insulation material e.gfoam or fibreglass batt stops the air movingIf you squash more insulation material into the space you might actually make the situation worse as the glass itself is a better conductor than airIf you have a house with 6 studs then you can use 6 thick insulation which will be better than 4 with 4 studsIn an attic you can just lay thicker insulation on top of the joists to get better performanceIn practice most heat is lost through windows, or when someone opens an external door if the house is not designed with foyersThere's also some lost by conduction through studsSo there's a limit as to how much point there is in insulating the wall gaps.
There is a vapor barrier on the back of the insulation you can add extra insulation put one up then remove the barrier and squeeze it in It is easier to by the insulation in a higher r scale thats the thickness rateing and the heat/cooling efficency rateingPut in a higher r scale i put the highest r in my walls and its cool in the summer and warmer in the winter
How approximately leaving the put in insulation devoid of masking with drywall for long? The confronted insulation is compressedDoes the put in insulation strengthen outwards over the years? If it does strengthen, does that reason a venture? might that's okay to end all insulations and after few weeks end drywall?
