Attics are one of the biggest sources of air leaks in homes and, therefore, it’s essential that they are correctly insulated. But what are the right types of insulation? What is the best material?
Attic insulation is one of the most effective methods to reduce the penetration of extreme temperatures into the living space. The heat that falls on the shingles of the roof causes a serious rise in the temperature of the enclosed attic space. In turn, this transferred heat is apt to seep into the rest of the dwelling through unsealed cracks and holes. Similar it is with cold winter temperatures that force the shivering home dwellers to increase their use of the heating system to escape the biting cold. In either case, the result is increased energy and financial output.
Professionals can help with this—from the assessment of your current space to installation and final clean up—but it can help to know some information upfront.
> Blown-in cellulose is a highly effective, environmentally friendly insulation solution. Made from recycled newspaper and treated with borate for fire retardant, the even distribution of blown-in cellulose insulation makes for high-performance insulation that has come into increasing favor among green builders and building energy efficiency experts.
Thermal insulation, like fiberglass and cellulose, can be installed in the flooring, knee walls, etc. Radiant barrier/reflective insulation is installed under the roofline, to help your roof reflect, rather than absorb, heat from the sun and keep your home cooler and more comfortable. Radiant barriers are ideal for hot climates (like Florida and Southern California). Here in New York, blown-in/loose-fill and batt insulation are more effective.
The best type of insulation for the attic (and other areas of your home) mainly depends on where you live.
When attic insulation is installed correctly (and consists of the right materials and right amount), it can help:
- Maximize your home’s energy efficiency and reduce your utility bills
- Increase your home’s interior comfort levels
- Improve the efficiency of your HVAC system
- Contribute to a healthier environment
When it comes to energy efficiency, nobody’s home is a perfect 10 out of 10. There are always solutions for improving this and making your home more energy-efficient and comfortable all year long. One of the best solutions is installing insulation.
As you’re getting ready to insulate your home, one of your first questions will most likely be, “How much insulation do I need?” The amount of insulation your home needs primarily depends on two factors:
- The region you live in
- The area of your home that needs to be insulated
