Sonarol Perfectherm PVC Window

Sonarol Perfectherm PVC Window

The Sonarol Perfectherm PVC Window uses a Class A, six-chamber PVC-U profile with a non-flush sash. The sash sits offset from the frame rather than sharing one flat exterior plane, giving the window a defined layered profile when viewed from outside. Sonarol specifies an 80 mm frame and an 80 mm sash depth. Narrow rebates around the glass create a slimmer visible border and leave more of the glazing area in view, balancing the substantial profile depth with a more open-looking window face. The system accommodates insulating glass units up to 48 mm thick; Sonarol lists Ug 0.5 W/(m²·K) for a glass package reference. Ug describes the glazing unit, not the complete window. Middle gaskets are fitted in the frame and sash, adding a sealing line within the profile construction. Together, the multi-chamber section, non-flush sash, and gasket arrangement define the specific character of Perfectherm rather than a generic PVC profile. The profile geometry also provides the framework for the glass, hardware, and surface treatment selected for the finished window. Its narrow rebate detail is particularly useful when the design calls for a larger apparent glass area within a full-depth PVC frame.

Profile, Sealing, and Hardware Details

Sonarol lists MACO MULTI-MATIC hardware for Perfectherm, together with an anti-wind latch, anti-burglary hooks, and a sash lifter with protection against an incorrect handle position. The anti-wind latch and anti-burglary hooks add named locking components, while the sash lifter helps prevent operation with an incorrect handle position. The manufacturer's accessory categories include glass, handles, air inlets, and glass dividers, giving the broader range both functional and decorative choices. Perfectherm profile cores are listed in white, brown, anthracite, and caramel. Surface options include white, anthracite, wood-grain decors, and other colors, so the visible foil can be coordinated with the room or exterior palette. A matching core and surface treatment can keep the profile edge visually consistent, while a contrasting finish can make the window a more defined element in the facade. Manufacturer reference choices and values depend on the selected profile, glazing, hardware, dimensions, and assembly. The combination of Class A six-chamber profiles, middle gaskets, MACO hardware, and a non-flush sash makes Perfectherm a specifically equipped PVC window design. Glass and finish choices can then be aligned with the building's appearance while retaining the system's documented construction features.
