When choosing a home, people tend to focus on location, design, and price.
However, "insulation performance" greatly influences comfort after you start living there.

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."
