Product Details
The DERCHI smart aluminium window is an aluminum casement window built with a 1.8mm profile thickness and 118mm frame width, incorporating a DERCHI insulation strip within the aluminum profile. The sash operates through outward opening or awning action, supported by a 13-inch flat open friction hinge independently developed by DERCHI for stable outward sash operation. Glazing uses double tempered glass with argon gas fill in a 5mm+27A+5mm configuration separated by a PVDF aluminum strip. Hardware comprises a WEHAG handle and WEHAG hinge, paired with a black six-point lock carrying an invention patent and a WEHAG lock point and lock seat system. The production process spans surface treatment, profile processing and cutting, glass cutting and aluminum strip installation, opening panel installation, frame and casing assembly, troubleshooting and sealing, and packing. DERCHI supplies the complete window system including profile, hardware, accessories, glass, and finished products ready for installation.
Procurement teams should confirm the glass configuration, color finish, opening layout, and package option before ordering, because these selections determine both thermal performance and project lead time. The window system carries NFRC, CE, AS2047, CSA, and ISO9001 authorizations, with delivery running 25-35 days after deposit and drawing confirmation and a 10-year quality warranty covering frame colorfastness and hardware operation under correct use. Buyers should verify that the chosen glass configuration and argon fill satisfy project energy-code requirements and request size-specific thermal calculations where energy compliance is critical.
Product Features
- The WY-118L window features an outward opening and awning configuration. Select this opening way for installations where inward swing is obstructed by interior fixtures.
- The WEHAG handle is available in black, silver, and antique bronze finishes. Choose these finishes to match hardware to interior design palettes.
- The system includes a six-point locking mechanism with an invention patent. Specify this lock for projects requiring enhanced security.
- The window uses a 13-inch flat open friction hinge. Choose this hinge for stable outward sash operation on larger openings.
- The glazing consists of double tempered glass with argon gas and a PVDF aluminum strip. Select this glazing for thermal and acoustic performance.
- The window achieves a U-factor of 0.23 and an SHGC of 0.20. Specify these metrics for energy code compliance in heating-dominated climates.
- The sound insulation rating is 35 dB. Choose this rating for acoustic comfort in urban environments.

Basic Parameters
| Performance Dimension | Product Value | Meaning & Test Evidence to Request |
|---|---|---|
| Thermal Insulation | U-factor 0.23; SHGC 0.20; Standard DERCHI insulation strip | Compare thermal ratings using the declared U-factor, test method, specimen configuration, and project boundary conditions. Request the thermal test or simulation report along with the declared product configuration (NFRC / ISO 10077-2). |
| Wind Pressure Resistance | 5 kPa | Review wind resistance against the specified test pressure, specimen size, anchorage method, and acceptance criteria. Ask for the wind-pressure test report and verify that the tested specimen and installation conditions match the project (ASTM E06.51 / FGIA NAFS / ISO 6613). |
| Water Tightness | 700 Pa | Assess water tightness by checking the test pressure, spray exposure, specimen configuration, and leakage criteria. Obtain the water-penetration test report and confirm the tested pressure and assembly configuration (ASTM E06.51 / FGIA NAFS / ISO 6613). |
| Air Tightness | 1.2 m³/(m·h) | Evaluate air tightness against the pressure differential, specimen area, reporting units, and tested configuration. Request the air-leakage test report and verify its pressure and specimen configuration (ASTM E06.51 / FGIA NAFS / ISO 6613). |
| Sound Insulation | 35 dB | Compare acoustic ratings using the stated laboratory method, specimen construction, glazing type, and reported metric. Ask for the acoustic test report and confirm that the tested construction matches the proposed configuration (ISO 10140-1 / ASTM E90). |
