About Washington, DC Insulation Companies

Proper insulation can turn a noisy, drafty home into a comfortable, energy-efficient refuge from the harsh weather. In a well-insulated house, the heating and air conditioning system needs relatively little energy to maintain a comfortable temperature—leaving you with a more quiet system, a smaller carbon footprint, lower bills, and a cozier home. 

There are many types of insulation available to choose from. Fiberglass insulation, which comes in blankets of material or a loose fill form, is the most common type of insulation on the market. Cellulose insulation is made from flame-retardant material mixed with paper and is particularly suited to upgrading older homes. Open-cell and closed-cell spray foams will help insulate your home while keeping it tightly sealed and protecting it from water and mold.

Many homes, especially those built before 1980, are not adequately insulated. Some simply need more insulation, while others were originally insulated with material that allows thermal energy to pass through it too easily. If you live in an older building and frequently deal with unexpectedly high energy bills, an insulation update can help improve your home’s energy efficiency. Call a Best Pick insulation contractor to determine the best place to add new insulation in your home.
