Wital Prestige Therm Light PVC Window System

Wital Prestige Therm Light PVC Window System

The Wital Prestige Therm Light PVC Window System is a six-chamber profile system with an 80 mm construction depth and a 113 mm frame-and-sash assembly. Wital presents the combined profile as a slim visible arrangement intended to leave more of the opening for glass. The profile supports glazing up to 51 mm thick, so the fabricator can select a compatible unit for the desired window build. Therm Light’s MD build adds a central seal, while a supplementary gasket in the sash glazing chamber provides another sealing detail. The system also uses internal profile chambers for ventilation and drainage of rainwater, along with calcium-zinc stabilizers in the PVC formulation. For appearance, Wital lists four profile-core colors—white, brown, caramel and anthracite—and 38 laminated foil types. The core color and foil finish provide different ways to coordinate the frame with the building exterior or interior. Wital states Uf of 1.0 W/(m²K) for the frame-and-sash profile combination. Separately, the manufacturer gives Uw of 0.72 W/(m²K) for a reference window measuring 1230 × 1480 mm with Ug 0.5 W/(m²K); this is a complete-window sample value and not the profile Uf. Therm Light technical materials include both AD and MD profile sections, with the central seal documented as an MD build option. The system’s depth, glazing capacity, seal details and surface palette describe a versatile base for contemporary PVC window designs.

Therm Light profile, seals, and finish options

The central seal is an available MD arrangement within the Therm Light profile family; the manufacturer catalogue also documents AD sections. That choice sits alongside the system’s shared six-chamber geometry, 80 mm depth and glazing support up to 51 mm. The added gasket in the glazing chamber complements the profile’s sealing layout, while internal chambers are designed to ventilate the profile and drain rainwater. These are construction features of the system, with the final profile arrangement determined by the selected build. The 113 mm frame-and-sash assembly gives the profile a compact combined face dimension, a detail Wital associates with allowing a larger glazed area. The profile’s thermal data distinguishes the frame-and-sash Uf value of 1.0 W/(m²K) from the reference window Uw value. Manufacturer system figures and reference values depend on the selected glass, dimensions, profile variant, reinforcement, hardware and fabrication. Surface design is another defining choice: four colored cores and 38 foil types allow the fabricator to coordinate the visible frame with the project palette. With its deep profile, narrow combined frame-and-sash measurement, supplementary gasket and adaptable finish options, Therm Light brings both construction detail and appearance flexibility to a PVC window design.
