Installing insulation in exterior walls did not use to be a priority.Saving energy was not so important and energy costs were less than today. In most cases, attic and basement wall insulation was enough,once there was proper drywall installation, especially in the basement, there wasnot much reason to improve or upgrade the existing insulation according to the building code – in the majority of these cases,and homes had absolutely no wall insulation.
Today, homeowners tendto cut their bills and reduce energy costs with installing better insulation in walls or in a such specific space like the basement with its excess of humidity, moisture and mildew, as a result, respiratory and other detrimental health problems have been identified again and again in our homes with the basement as its epicenter.
Many homeowners face with thebig issue – how to insulate a finished space without tearing it apart. In this case, the most popularmethod of the “drill-and-fill” makes the most sense. In residential homes where exterior walls feel cold, the “drill and fill” method is a cost-effective solution. With professionally installed insulation in walls, the long-term benefits are worth the investment.
“Drill-and-fill” is an innovative method of effective insulation of finished walls. It is perfect for both interior and exterior walls that have been finished with proper drywall installation. The biggest benefit of retrofit drill-and-fill is the possibility of its installation from the interior or the exterior walls of the home. After retrofitting these walls with new insulation, the home is much better insulated, heating bills are reduced,walls, ceilings, and floors are warmer in the winter and cooler in the summer. An insulation retrofit is simply an upgrading to ensure that “conditioned” air is kept within the home.
How does it work? Professional installers drill holes into existing drywall, targeting cavities that are behind the drywall. Then, loose fill cellulose insulation is blown into the drilled holes, filling the wall cavities with insulation between the wall studs. When the wall cavities are full, the drilled holes are patched, and additional drywall taping can be provided.Because loose fill insulation easily conforms to a given space, it does not disturb or disrupt any physical structure – like enclosed, pre-existing walls. This means that an insulation upgrade can be performed without the need to do a full-scale renovation. In fact, the drill-and-fill approach can be performed on drywall, plaster, stucco, brick, wood siding and even vinyl siding.
