Attics are a very important area of the house to be well insulated. Without proper attic insulation, heat will be constantly escaping your home and your energy bills will be expensive. Insulation for older homes is critical in Northeast areas like Baltimore, Maryland, where a lot of heat or cold air can escape from or into the attic.
Attics can be insulated with a variety of products:
Loosefill Blown Fiberglass / Cellulous: great for retro-fitting existing houses. This insulation is simply installed by blowing the new material overtop of the existing insulation in order to achieve the recommended R-Value.
