How to do insulation for basement
It is important to insulate your basement properly in order to reduce the risk of leakages and mold growth, as well as reduce noise levels and energy bills. Homeowners are always ready to insulate the rooms they live in, but often overlook the basement. Lack of proper insulation leads to increased humidity levels, because the walls do not have enough sealing properties. If you wish to seal your basement and make it imperious to water, temperature fluctuations and avoid mold growth, you should use rigid foam insulation. This type of insulation offers a more effective air barrier than fiberglass, cellulose or cotton. You can use rigid foam to insulate both the interior and the exterior of foundation walls. An insulated basement reduces thermal bridging, raises the R-value of the house and improves air tightness.
The importance of installing vapor barriers
One of the biggest challenges when it comes to basement insulation is the fact that the walls of the basement are cold and have high excessive water vapor from leakages. The main sources of water vapors are the foundation walls and the concrete floor, so it becomes essential to install a vapor barrier and ensure the water vapors do not work their way through the concrete and walls. Concrete works just like a sponge and holds water for years. After years of accumulation, the water will penetrate the insulation and cause serious mold problems, not to mention that they will destroy the walls. Water vapor barriers will help reduce the risks of accumulations penetrating the walls.
Rigid foam insulation
A couple of years back, fiberglass was considered the best solution to insulation, but at the moment rigid foam insulation has taken the first spot. We live in a period when science offers more and more efficient solutions to problems helping the building industry to advance quickly. Rigid foam insulation is superior and represents a proper vapor barrier. Unlike fiberglass, which is easily penetrated by water and becomes the perfect environment for mold growth, rigid foam offers proper protection against mold growth.
Avoid basement insulation common mistakes
One of the most common mistakes when it comes to basement insulation is failure to install the insulation correctly. What is more, the work is covered in the end, so it might take years until you discover the problem. The results are terrible: severe mold and mildew problems as well as increased heating bills. It is important to understand that basement should not be insulated like you would a normal living space. Lack of light, cold walls and water vapors are natural occurrences in the basement, so using fiberglass to insulate the basement is the worst decision possible, as it would only help with mold and mildew growth. If you need to insulate your basement, you should use only experienced builders that understand the problem perfectly. A contractor that underestimates the role of vapor barriers and vapor transmission is not worth your time.
