SUBSCRIBE to This Old House: http://bit.ly/SubscribeThisOldHouse Tom showed Kevin 3 types of insulation: Spray foam, fiberglass and blown-in cellulose. Insulation specialists can be contracted to install spray foam and blown cellulose. Fiberglass insulation can be found at the local home center. Cost: Varies by Insulation Choice and Application Skill Level: Moderate to Professional Steps: Fiberglass insulation is sold by wall thickness and that should be adhered to so the insulation doesn’t get compressed and lose effectiveness., Open cell spray foam has the same R-factor as fiberglass, but it goes around any penetrations and acts as an air infiltration barrier., Closed cell spray foam has a higher R-factor per inch, but it is more expensive., When retrofitting, cellulose, made from recycled newspaper, can be dense packed into the stud bays.
