Installing Home Insulation has been standard practice in all new homes as of January 2012 as per the new building legislation in South Africa. We are therefore all aware of the benefits of installing Roof Insulation. However, one of the areas that many people never consider is Underfloor Insulation.
In fact, the benefits of Underfloor Insulation are just as significant as the Ceiling Insulation. If your home excessively cold in winter and you have mold and condensation in the home. Therefore you will need Underfloor Insulation in the home.
As a direct result of installing Under Floor Insulation homeowners will have the benefit of a warmer home in winter. In Fact, wooden floors are especially vulnerable to moisture. As a result, Underfloor Insulation will create a vapor barrier thereby preventing moisture and condensation from entering the home.What Is Underfloor Insulation
In many of the older homes, there is a cavity space under the floor this cavity space has ventilation for breathing under the floor as well. In fact, on cold winter days, the airflow under the floor increases the potential for the home to be far colder.
The reason being these insulation materials have excellent insulation properties as well as soundproofing benefits.
Homes with raised floors and a cavity space below will have a draft under the floors. The wooden floor will always contract and expand in summer and winter.
As a result, the floors in winter become freezing cold and allow air to flow through into the home. Many homes end up with stained floors as well as gaps in the wooden floors as a result of the moisture and contraction and expansion.
Create a Vapor Barrier and Reduce Condensation
As a result of Underfloor Insulation, a vapor barrier will be created. Wooden floors are especially vulnerable to condensation and moisture. Therefore installing a layer of Underfloor Insulation will improve this situation substantially.
How Under Floor Insulation Is Fitted
Gain entry either from the side hatch or cutting a trap door from above on the wooden floors and refitting after the installation. In most homes, the Floor beams are between 300mm and 400mm apart.
The application is to cut the insulation slightly wider than the beams and fit with foil below. The foil creates a seal to restrict the cold air movement from below. The insulation stops the cold air from entering the home.
Wire strainers or foil stapled to the underfloor will hold the Under Floor Insulation in place.
Benefits of Underfloor Insulation
Improves Indoor temperature in winter as a result of Underfloor Insulation.
Reduces the potential for condensation substantially
Noise Reduction benefits are substantial
Reduce the musty smell in the home.
