The exterior aluminum acts as a protective shield against UV, weather, and corrosion, extending window lifespan without frequent maintenance. The interior PVC ensures optimal thermal insulation, while the exterior aluminum provides a clean architectural finish and allows custom painting in any color to perfectly match your building's style.

The KF410 Home Soft is custom-manufactured to your exact opening dimensions. Installation takes place within the existing PVC-aluminum frame or wall, with foam sealing and anchor sealant to ensure continuous thermal insulation. We recommend professional measurement and installation by a certified Internorm specialist to guarantee optimal thermal and acoustic performance.

The interior PVC requires only periodic cleaning with water and mild soap, with no need for painting or additional treatment. The exterior aluminum is protected and requires no special maintenance, just occasional rinsing. Multi-point hardware should be checked annually, and light lubrication with neutral oil will ensure smooth operation and secure closure for decades.
