We achieve a comfortable indoor environment that is less affected by outside temperatures.
"Inplus" is a resin-made inner window that has excellent insulation properties, with a thermal conductivity of about 1/1000 compared to aluminum. The air layer created between the existing window and the inner window makes it difficult for indoor heat to escape outside, demonstrating its insulation effect. A home with improved insulation is more efficient for heating and cooling, making it economical. *Please feel free to contact us for more details.*
