Upgrade your existing windows! Experience the effects of "insulation, soundproofing, and security" with inner windows plus!
By adding another window, called an "inner window," to the indoor side of the existing sash window, you can upgrade your current window to an insulated, soundproof, and security window while keeping it as is. The air layer between the existing window and the newly installed inner window provides insulation. This reduces the heat exchange through the window, leading to lower heating and cooling costs. Additionally, the thermal conductivity is one-thousandth that of aluminum, which reduces uncomfortable condensation caused by the temperature difference between the outside air and the room temperature. 【Features】 ■ Add another window to the indoor side of the existing sash window ■ The air layer between the existing window and the newly installed inner window provides insulation ■ Reduces heat exchange through the window, lowering heating and cooling costs ■ CO2 emission reduction equivalent to 137 beech trees per year ■ Reduces uncomfortable condensation caused by the temperature difference between the outside air and the room temperature *For more details, please refer to the PDF document or feel free to contact us.
