Crawl Space Insulation
Tips on Crawl Space Insulation Installation
Crawl space insulation is basically installed to keep your home warmer especially during winter. When you effectively to do so, you will in turn be able to save money on heating expenses. While installing this type of insulation is not difficult, you should first study the proper way of doing to be efficient.
Where to Install Crawl Space Insulation
You can install crawl space insulation in two different ways. One, you can install it on the exterior walls of your space. Alternatively, you can also do it on the crawl space ceiling under the flooring of your home. One important aspect to consider is whether your space is ventilated as only unventilated crawl spaces should be insulated.
In most instances, it is advised that you install crawl space insulation on the exterior walls. And the recommended material for this type of installation is fiberglass batt. When doing this kind of installation it’s essential that the insulation is fitted from the top to the ground to a few feet under. To fasten the insulation, you need to get a wood strip and attach it to wall. And then you can simply attach the insulation to the wood strip that is attached to the wall. Of course, you could simply just staple the insulation at the top of the wooded strip and allow it to drape into the whole area. However, your crawl space is susceptive to mildew and molds. That is why you need to put a vapor barrier when you install the insulation into the exterior walls too. This will help block the moisture that’s trying to seep into your crawl space. This is important as exterior walls should only be insulated if you are sure it will remain dry year in and year out. This type of insulation should also be done in areas that are not ventilated to the outside. If there is ventilation, the vents should be blocked.
Alternatively, crawl space insulation is installed under the floor when the place is ventilated. If you are following this option, make sure that you also insulate the water pipes and ducts. Otherwise, your water pipes and ducts could burst come winter. For this installation you can use unfaced batt or you can also use fiberglass that has a foiled vapor barrier if moisture is a concern. If you use reflective materials, they can also be more effective in keeping the floor warmer especially during winter.
Other Factors to Consider
Another factor to be considered is the climate in your area. Insulation products are generally rated according their efficiency in terms of flow resistance and the rating is usually indicated by an R value. Depending of your geographical location, there would be an R value of crawl space insulation minimum requirement. Of course, it would be better to install beyond the minimum requirement for a more efficient insulation if the budget allows.
Of course, building codes need to be considered as well as the direction your home faces too. If you are not sure about the building codes, it would be safer to consult your local building office or a contractor to ensure that you are installing the most appropriate crawl space insulation.
