## Is Your Home Okay with Summer Heat and Winter Cold Problems?
When choosing a home, people tend to focus on location, design, and price.
However, "insulation performance" greatly influences comfort after you start living there.
In recent years, severe summer heat and winter cold have continued, increasing reliance on air conditioners.
Consequently, many people are concerned about the burden of utility costs.
Therefore, in collaboration with Cuore Home Co., Ltd., we conducted a survey targeting 400 men and women nationwide who answered in a preliminary survey that they "currently live in a detached house they own" regarding "Housing Insulation Performance and Indoor Comfort."
