If your home tends to be uncomfortable during seasonal extremes, a poorly-insulated attic may be part of the problem. In today’s post, local roof repair and installation company Berry Roofing & Solar shares important things you should know before adding attic insulation.
The Energy Envelope
To understand how attic insulation works, let us first discuss what the energy envelope is. The energy envelope is an enclosure that consists of the roofing system (which includes the attic), the exterior walls, and the fenestrations installed on them: windows, skylights, and entry doors. One thing these components have in common is insulation.
An energy envelope, when properly insulated, slows down thermal transfer. This results in heat retention during winter and resistance to heat infiltration during summer, which results in consistent indoor temperatures, comfortable indoor spaces, and energy savings.
Why Is Attic Insulation So Important?
Residential and commercial roofing systems are constantly exposed to sunlight. Without insulation, solar heat would radiate indoors, resulting in uncomfortably warm indoor spaces. The air conditioning system would then increase its output, leading to high energy bills. A properly insulated attic helps keep the heat outside the energy envelope. During the cold season, it also helps keep indoor heating requirements at minimal levels.
Important Considerations for Attic Insulation
Before you start looking up attic insulation contractors, there are a few things you need to consider:
Insulate Both the Roof and Attic Floor — An unfinished attic either has an insulated floor or roof. Having insulation on both not only doubles the amount of protection against radiant heat, it also makes it easier to have your attic converted as a home addition.
Not All Insulation Products Are the Same — Ask your insulation contractor about the insulation products that they offer. Compare how much R-value (heat resistance) a particular insulation product adds to the roof compared to the others. Ideally, you should find the product that has a good balance between cost, insulation, and long-term performance.
Roofing Issues Must Be Addressed First — You won’t get to reap the full benefits of an insulated roof if it has fundamental problems like leaks or issues with its structural integrity. Your roofing contractor may need to perform repairs to your roof before they can apply new insulation.
