Whether you are building a new home or renovating your current home, you need to know the difference between batt and blown in insulation for your attic. Both insulation systems come with certain negative and positive aspects, and this guide will help you determine which type of insulation works best for you.
Batt insulation is the type of insulation that comes in large fiberglass rolls. Although it is possible to create a very efficient seal with batts, it takes a great deal of patience and precision to make sure that all the seams are insulated. It typically takes much longer to create an airtight seal with batts than with the blown-in alternative. If sealed properly, however, batt insulation actually has the potential to create higher R-Values, meaning that heat transfer will be less than with blown-in insulation.
Blown in insulation, first and foremost, will typically need to be installed by a professional, so if you are hoping to put in the insulation by yourself, blown in insulation may not be the best option for you. On the other hand, blown in insulation generally creates a more efficient seal and will produce good results after a relatively quick installation period.
