High-Performance Window, Door and Glazing Solutions for Residential, Hotel and Commercial Projects
uPVC Aluminium Window Door Systems Europe solutions from WTBCompany are developed for residential, hotel, apartment, villa and commercial projects requiring reliable window, door and insulated glazing systems.
WTBCompany supplies uPVC, aluminium and insulated glass window and door systems for European construction and renovation projects, with project-specific configurations selected according to architectural design, thermal insulation targets, acoustic requirements, climate conditions and opening dimensions.
Our solutions include high-insulation uPVC window systems, aluminium windows and doors, entrance doors, balcony doors, tilt-and-turn windows, sliding systems, large glazed openings, double-glazed insulated glass and triple-glazed insulated glass configurations.
For European projects, window performance must be evaluated as a complete system. The final performance is influenced not only by the profile itself, but also by the frame construction, glazing unit, spacer system, seals, hardware, dimensions and installation conditions. For this reason, WTBCompany evaluates each project according to the required technical specification rather than offering a single standard profile solution.
Depending on the project requirements, different profile depths, chamber configurations, glazing thicknesses, opening systems, colors, finishes and hardware options can be coordinated to create the most suitable solution for the building envelope.
WTBCompany supports projects across Germany, the Netherlands and other European markets with coordinated technical evaluation, custom production, glazing configuration, hardware selection, export packing and international delivery.
Our project-based approach is suitable for both new developments and renovation projects, where energy efficiency, durability, architectural appearance and long-term performance are critical to the overall building design.

Double and Triple Insulated Glass Systems for European Projects
WTBCompany supplies double-glazed and triple-glazed insulated glass configurations for uPVC and aluminium window and door systems intended for European residential, hotel, apartment and commercial projects.
The glazing package is not selected only by the number of glass panes. For European projects, the complete window and door system is evaluated according to the required performance values, including thermal insulation, air permeability, watertightness, resistance to wind load, acoustic performance, solar control and safety requirements where applicable.
European window and external pedestrian door performance is commonly evaluated under EN 14351-1, while insulating glass units are covered by the EN 1279 series. The EN 1279 framework includes product requirements, long-term moisture penetration, gas leakage, gas concentration tolerances and factory production control for insulating glass units. Triple-glazed units are also covered within this framework.
Depending on the project specification, glazing solutions can be configured with:
- Double-glazed insulated glass units
- Triple-glazed insulated glass units
- Low-E coated glass
- Argon-filled cavities
- Warm-edge spacer systems
- Laminated safety glass
- Tempered safety glass
- Acoustic glass combinations
- Solar-control glass
- Different glass thicknesses
- Project-specific cavity widths
- Performance-oriented glazing combinations
The final glass build-up is selected together with the profile system, spacer, seals, frame dimensions and hardware in order to meet the required project performance.
For energy-efficient buildings, it is particularly important to distinguish between Ug and Uw values.
Ug refers to the thermal transmittance of the insulating glass unit itself.
Uw refers to the thermal transmittance of the complete window, including the glazing, frame and edge effects. Under EN 14351-1, Uw is the relevant declared thermal value for the complete window.
This means that a low Ug value alone does not guarantee that the complete window will achieve the required Uw target. The complete system must therefore be evaluated together.
WTBCompany can coordinate glazing configurations according to the technical requirements of the destination country, architect, consultant, project specification or energy-efficiency target. Where higher thermal performance is required, suitable triple-glazed configurations, Low-E coatings, gas-filled cavities and improved spacer systems can be evaluated together with the selected uPVC or aluminium frame.
Double & Triple Insulated Glass Configurations
Insulated glass units can be configured according to the thermal, acoustic, safety and environmental performance required by the project and destination market.
Glass Unit Thermal Value
Thermal transmittance of the insulated glass unit itself.
Complete Window Thermal Value
Overall thermal performance of the complete window including frame, glazing and edge effects.
