Why Green Attic Insulation Is Essential During Summer

While it's widely known that insulation keeps the house warm during winter, its role in maintaining coolness during summer is often overlooked.

‍

We typically envision home insulation as a protective layer against the cold, akin to a snug winter coat for our houses. While this analogy holds true to some extent, insulation performs differently in summer. Just as wearing a heavy winter jacket in hot weather would cause discomfort, insulation within homes helps repel the heat of summer, ensuring interiors remain pleasantly cool.

How Insulation Works

Home insulation absorbs heat produced by heating systems during winter and prevents the infiltration of hot air from the attic, where temperatures often soar during summer days. This enables more efficient operation of air conditioning systems, leading to reduced energy consumption and lower utility bills.

Heat travels through three primary mechanisms: conduction, convection, and radiation. Insulation traps heat by countering these processes:

Conduction involves the transfer of heat through materials, such as the transmission of body heat through a down jacket. Similarly, during summer, heat infiltrates homes as sunlight heats the roof, gradually raising indoor temperatures.

Convection entails heat transfer through air movement. Many insulation types incorporate air pockets to trap and contain heat.

Radiation refers to the emission of heat from a source, such as radiators or wood stoves. Insulation inhibits the penetration of external heat sources into the home.

Where Should Insulation Be Installed?

Ideally, homes should be insulated from top to bottom, encompassing attics, walls, ceilings, floors, crawl spaces, basements, and areas around ducts and piping. Proper insulation prevents outdoor heat from seeping in, maintaining a comfortable indoor temperature. Without adequate insulation, homes can become uncomfortably warm as heat infiltrates through various entry points, disrupting the internal climate balance.

Selecting the Right Insulation for Summer

Consulting a professional can help homeowners choose the most suitable insulation type based on their specific needs and home characteristics.
