Custom glazing for windows, doors, and large glass panels
The right glazing for insulation and living comfort
Glass determines a large part of the insulation, natural light, safety, and daily comfort of your windows. Therefore, VINCK does not automatically choose the same glazing for an entire home, but tailors the glass construction to the facade, room, orientation, and application. For new windows and doors, we view the profile, glass, dimensions, and installation as a single unit, for both Reynaers aluminium windows and PVC windows . For instance, a street-facing facade may require more attention regarding sound insulation and privacy, while on a sunny garden side, insulation, solar heat, and large glass surfaces become more important. Those undertaking energy-efficient renovations will also read how new windows and the right glazing can contribute to better energy performance and your EPC score .
Double glazing, triple glazing and high-efficiency glass
High-efficiency glass forms the basis of modern energy-efficient windows. Double glazing consists of two glass panes with an insulating cavity, while triple glazing adds an extra glass pane and a second cavity. Triple glazing can offer a lower Ug value and therefore stronger thermal insulation, but it is not automatically the best solution for every home or window. Glass weight, window dimensions, profile choice, orientation, solar transmittance, and the insulation level of the home must be assessed together. This overall glass construction is particularly important for very large glass surfaces and Hi-Finity sliding windows . Therefore, in our advice, we consider not only how many glass panes are needed, but above all which glazing offers maximum comfort .

Safety glass, laminated glass and glass for low windows
Safety glass receives extra attention for doors, low windows, large glass panels, and locations where there is a risk of impact or falling through. Laminated safety glass consists of glass panes with strong intermediate layers that help hold glass shards together in the event of breakage. The required composition depends on the position, dimensions, height, application, and safety risk. This is particularly important for large aluminium sliding windows , glass doors, and window surfaces that start close to the floor. In the case of glass balustrades , too, glass must be viewed as a technical safety element and not merely as a transparent infill. You can find more background information in our advice on when and for what purposes laminated glass is required .
Acoustic and solar control glazing
Those living near a busy road, railway line, or other noise source can improve their living comfort with a customized acoustic glass construction. In this regard, not only double or triple glazing is important, but also the combination of different glass thicknesses, laminated layers, and the performance of the entire window. On south- and west-facing facades, solar heat plays a greater role. Solar control glazing can help limit the amount of heat entering through large glass surfaces, but it must remain in balance with natural daylight and the view. For large windows, we therefore combine glass with efficient external sun shading and screens where necessary. Large sliding windows, in particular, require a careful balance between light, insulation, acoustics, and solar load; we delve deeper into this in our article on aluminium sliding windows for new construction and renovation .

Glazing for sliding windows, verandas, and glass facades
The larger the glass surface area, the more important a technically sound glass selection becomes. For wide sliding windows, custom-made conservatories , and aluminium glass facades , glass weight, thermal insulation, solar load, safety, and usage together determine the suitable composition. Privacy can also be incorporated using frosted, translucent, or other customized glass types without losing excessive daylight. Because VINCK produces aluminium exterior joinery in its own workshop in Sint-Niklaas , the profile, glass weight, dimensions, and technical execution can be coordinated right from the preparation stage. In this way, glazing does not become a separate component, but an integral part of windows, sliding windows, conservatories, and facade constructions.
Which glazing suits your home best?
Are you unsure whether to choose double or triple glazing, do you want more sound comfort, less solar heat, or do you need to know where safety glass is required? VINCK assesses every home and glazing unit individually and tailors insulation, safety, acoustics, sun protection, and appearance to your wishes and the technical possibilities of the project.
