Blown in cellulose attic insulation. What do you think about it?

Answer 1

Many areas have banned Cellose insullation which is treated with a fire retardant (Borax solution). This was done because the fire retardant leaches out of the insullation (usually over a period of about 10 years) due to heat in the attic. Without the fire retardant is posses a potential fire hazzard.

Another problem with blown in insullation is it can block roof ventilation if it is not done properly. If you are in an area that has a lot of high windy days, the blown in insulation can drift like sand in a dessert.

Bat insulation tends to stay where they are laid. It is more costly to install properly. Again, care has to be taken not to block attic ventilation.

Do google and/or yahoo searches on insulation contractors. Look for complaints and resolutions; insurance coverage; properly licenced; registration of company (has it expired - some ltd and inc companies still after the charters have been voided for some reason).

When you have found at least 3 companies that you would consider hiring, have the come and give you a written estimate (many companies do not like giving written estimates).

The wriiten estimate should state the work to be done with costs, extras and costs, guarantee, financing terms.

Good Luck

Answer 2

I had both blown in insulation and bat insulation added to my attic.

The blown in (hired out to professional) was nice because it could get into all the areas that I couldn't crawl into myself. I installed the bat insulation wherever I could reach.

I do believe that the bat has more insulation value, but I don't know for sure.

Having insulation is better than having none.

Answer 3

Air in the insulation makes it work. Blown-in settles after a time and removes the air. It is better than nothing but is not as good as batt insulation.

First The best means you'll reason a mould moisture main issue is if in case you have a plastic seal duvet on best..... ----This can bounce your insulation ranking proper via the roof You simply placed a hurricane window in your ceiling-- .....to maintain the moisture within the insulation and should you do you have got to have respiring flaps within the plastic duvet to permit water in encase you do ever get a roof leak and to permit the moisture vent out keep in mind moisture fog consistently lays in no way floats.
