Having a well-insulated attic is essential for keeping your home comfortable and energy efficient all year round. Fiberglass insulation usually needs to be replaced every 15 to 20 years, as it can easily become dirty, wet, moldy, and ineffective if there is a roof leak or water damage of any kind. Sealing and insulating your home can save you up to 10% on your annual energy bills and, at the same time, improve your home comfort in winter and summer. In general, it's a good idea to check your attic insulation every 5 to 10 years to ensure it's in good condition.
If you have four feet of insulation stacked all over the attic, this could affect how efficiently the attic can circulate air. If you have attic insulation with an R value of 38 and you still want your home to be more energy efficient, consider installing a radiant barrier instead. To avoid gaps and create a continuous thermal barrier, spray foam should only be installed when there is no other insulation. The first step is to inspect the attic and confirm that you need more insulation and, probably, some airtight sealing. If so, most people feel that the best way to get good results is to find a trained insulation contractor to do the work for you.
We provide high-quality insulation materials and ensure that, if you have faulty insulation, it is quickly replaced and properly installed. When used in an attic, fiberglass block insulation can help keep the attic cooler in summer and warmer in winter. Attic insulation is crucial both to keep your home comfortable all year round and to ensure that it is energy efficient. Attics are difficult to insulate because they tend to be irregularly shaped and have many nooks and crannies.
This comprehensive assessment will provide you with practical information about where your insulation may be failing and what difference a new or modernized insulation can make. Upon completion of the work, the contractor must provide you with documentation showing how much insulation has been added and what the new R-value of insulation is for your attic. If you want to get the best result with your new attic insulation, focus your attention on how it's installed. One thing to keep in mind about sealed or unventilated attics is that they lack the protection against heat buildup offered by ventilated attics for tiled roofs.
