How To Properly Seal Gaps In Walls, Doors, And Windows

By Jessica Roberts


Some homeowners and building administrators like to have their structures properly sealed in various spots where too much air carrying dirt with it can enter. This will save money, time, and effort spent on cleaning the place. There are many ways to do this using different materials or substances. Fiberglass is one of these. The most effective sealant, however, is provided by Spray Foam Insulation Companies NC.

The system totally insulates gaps and is a good air barrier in sealing gaps found on walls, floors, and ceilings. Some sometimes get unnoticed like those are in baseboards, electrical outlets, windows, and doors. This is sprayed as a liquid and expands as foam that will fill up every crack, crevice, and cavities. It is a petroleum derived substance called polyurethane plastic.

When this system is applied, it will provide a very protective barrier against invasive wind carrying with it moisture and dirt. This vapor will not be able to penetrate the blocking substance and cannot condense. Condensation is prone to molds and fungi that can cause material decay. This substance also is a very exceptional sound damper. Using this process will result in cost savings.

When we say insulation we do not mean the total sealing in its entirety, that would constitute a death chamber. All buildings need proper ventilation to retain good air quality inside and to reduce the chances of moisture turning into molds. Insulation therefore is what one can call a control system the prevents unwanted air in some areas.

Poor insulation actually accounts for forty percent of power wastage that is used in a household. That is according to some studies. This can be observed if you have an air conditioning unit and there are plenty of gaps in some walls, windows, and doors. That means your house is leaking and when it is leaking, you be spending more on power bills that will also make your pockets leak.

There are two types of this system. The first is called an open cell type. This is the most common form of spray insulator. These are very good at absorbing sound waves which will make a home very comfortable and quiet. These are mostly applied on walls and roofing undersides. A point five pound of this can expand a hundred times when applied.

The second foam type is known as close cell foam. Other usually identify it a rigid foam. This type has low vapor signature compared to the open type. This mostly is sprayed on structural components that are under the earth crust like cellars and basements. It can improve structural robustness because it really is dense and has a very strong compression property.

Soybeans and other plant derived foams are also available and have gained popularity as the world has become environmentally conscious. This type of foam is made of polyols from plants rather than from petroleum. Agricultural polyols have been in use for some time and are used to manufacture plastic furniture and other products. Some manufacturers only use a little of it and then boast that their product is green.

In selecting a foam sprayer, find one who is really very experienced. Do not settle for second best. It does not matter what type is used, an inexperienced applicator will leave behind a very messy job caused by over spraying and still leaving numerous gaps. The process is very technical that is why it is sometimes referred to as foam in place insulation.
