Adding a new layer of insulation on top of an existing one is possible, provided that the existing insulation is in good condition. The method of application, however, depends on the type of insulation that is already installed. For instance, block insulation, rolled insulation, and fiberglass or cellulose insulation with loose blown filler can be easily placed on top of the old insulation. This is a great way to keep your home warm in winter and cool in summer. It is important to note that the current insulation must be in good condition for this to work.
In most cases, you can add new insulation over the old one, unless the old insulation is damp, moldy, or vermiculite. If the old insulation is dry but seems to have been wet before, it is essential to find out the cause and fix the problem. The damp insulation must be removed or it may cause mold to form or rot the roof or roof beams. In general, a laminate or block insulation or a blown loose fill insulation (fiberglass or cellulose) can be installed on top of the old insulation. If you have an old insulator and want to add new material on top of it, it is important that the underlying insulator is not wet, damp or wet beforehand.
It's vital that a professional insulation technician inspects the current insulation before adding another layer. You may need insulation in the attic if you feel a stream of air coming out of the attic or if your heating bill is higher than it used to be. Unless you live in a house built specifically to save energy, you can probably save energy by hiring an Austin attic insulation contractor to improve the insulation of your attic. If your home's insulation has become wet or moldy, you should remove and replace it as soon as possible. Many people have some form of insulation in their attic, basement, or walls, but additional layers can help better insulate their homes. However, there are some circumstances in which it would be necessary to remove the existing insulation first, such as in the case of insulation contaminated by pests, water, or smoke. It is possible to reinforce the old insulation by simply placing a new layer on top of the existing installation.
However, there are some cases where you may need to remove the existing material and install new material (for example, if the existing insulation is old or damaged).
