The Center-Vent Slider Windows are three-track external screen thermal-break sliding windows with a 93 mm system wall occupation, suitable for Southeast Asia, Australia, coastal residences, villa kitchens, bedrooms, balconies, dormitories, and rental apartments.
- External screen sash slides independently with a maximum recommended width of about 1300 mm and uses 304 stainless steel safety mesh for mosquito, corrosion, and impact resistance.
- One-piece outer frame reduces splicing seams.
- DERCHI provides one-stop service from product consultation, scheme design, order production to delivery, with products having passed NFRC, AS2047, CE, CSA, and ISO9001 certifications.
Product Details
WT-93 is a three-track external screen thermal-break sliding window under the E2T new system, using a 6063-T5 thermal-break aluminum profile with PA66 thermal break strips and a continuous thermal break at frame, sash and track. Three independent tracks carry glass sashes and an external protective screen sash separately, so the screen sash does not occupy the glass sliding channel; the three-track structure places the screen sash on the outdoor side, keeping the indoor side for glass sash and handle operation. Glass sashes run on customized silent pulleys with stainless steel load-bearing components, and the track cooperates with upper anti-swing and anti-theft limit blocks to control sash jumping and lifting. The one-piece outer frame reduces splicing seams, and the track uses height difference and chambered drainage.
WT-93 is available in three-sash three-track or six-sash three-track combinations, with extended configurations including left-right fixed center opening, top light, bottom fixed and large-area combination windows. Adjustable items include fixed glass ratio, mullion position, glass type, mesh density, locks, drainage cover color and edge wrapping. For developers, the WT-93 value is integrating the screen into the system track rather than post-installed external hanging; for dealers, the 93 mm system depth, 1.8 mm profile and three-track safety mesh form a clearer upgrade gradient than ordinary two-track light windows. Product data can list finished width/height, three or six sash, opening direction, fixed area, glass construction, mesh type, color, handle and lock, edge wrapping and installation method by window number.
Product Features
WT-93 is a three-track external screen thermal-break sliding window under the E2T new system, corresponding to the Center-Vent Slider Windows title — identifies the system tier for specification matching.
Three independent tracks carry glass sashes and external screen sash separately; the screen sash does not occupy the glass sliding channel, so screen protection does not reduce glass openable area compared to two-track windows.
System wall occupation is 93 mm with indoor and outdoor main visible face about 43 mm — wall cavity and reveal dimensions are confirmed before ordering.
Profile is 6063-T5 thermal-break aluminum with outer frame and opening sash main wall thickness of 1.8 mm — profile grade and wall thickness are matched to structural and wind-load requirements.
PA66 thermal break strips measure about 24 mm (outer frame), 32 mm (fixed frame) and 15 mm (sash), forming a continuous thermal break at frame, sash and track — thermal-break continuity is confirmed for insulation-sensitive projects.
External screen uses 304 stainless steel safety mesh for mosquito resistance, corrosion resistance and impact resistance — mesh grade is selected for coastal or pet-occupied sites.
External screen sash slides independently with maximum recommended width about 1300 mm and is removable for cleaning — screen panel width is sized within the recommended limit.
Screen mesh bending adds only about 18 mm width with no height increase — reveal width is planned without additional vertical clearance.
Track cooperates with upper anti-swing and anti-theft limit blocks; hardware includes Moor bar lock, upper anti-theft block, universal transmission and limit accessories — security hardware level is specified for low-rise or ground-floor units.
Track uses height difference and chambered drainage; first drainage position is about 200 mm from side frame with staggered inner and outer holes and zinc alloy drainage covers — drainage configuration is selected for rain-exposed elevations.
Sliding overlap area uses siliconized weatherstrip — seal type is specified for air-tightness requirements.
Adjustable items include fixed glass ratio, mullion position, glass type, mesh density, locks, drainage cover color and edge wrapping, defined per window number in project data — configuration variables are set per opening.
Simulated performance grades: thermal insulation 5, sound insulation 3, water tightness 4, air tightness 6, wind pressure resistance 9 — grades are compared against project performance thresholds.

Single glass active sash range: width 350–1100 mm, height 500–1600 mm.
Single fixed glass maximum area: about 6 m².
Screen sash maximum recommended width: about 1300 mm.
Hardware Accessories
Standard hardware includes Moor bar lock, upper anti-theft block, and universal transmission and limit accessories.
Upper anti-swing limit blocks and anti-theft limit blocks cooperate with the track to control sash jumping and lifting.
Customized silent pulleys and stainless steel load-bearing components are used in the sliding system.
Zinc alloy drainage covers are fitted to the track's height-difference and chambered drainage design.
Optional key locks and limiters can be added for low-rise residences, balconies, and pet families.
Three-track structure places screen sash on the outdoor side, keeping the indoor side for glass sash and handle operation.
