Y109 Series Hurricane Impact Casement Windows

German WEHAG Hardware with 99% Antibacterial Protection

The Y109 uses German WEHAG handles available in silver, black, and gold to match different interior styles. Each handle surface carries a silver-ion coating tested to eliminate up to 99% of bacteria on contact, reducing germ transfer at the most-touched point of the window. The WEHAG hinges support up to 50 kg per sash, keeping large casement aluminum windows stable and smooth through years of daily operation.

Three-Way Sealing and Triple Insulated Strips for Energy Efficiency

This casement window uses a three-way sealing structure to block air and water infiltration at the frame-to-sash junction. Three independent insulated strips break the thermal bridge between indoor and outdoor environments, cutting heat transfer in both hot and cold seasons. Together, these layers give the Y109 the airtightness, watertightness, and wind-pressure resistance required of hurricane impact casement windows.

Hidden Anti-Backflow Drainage

System

The Y109 eliminates visible drain holes on the exterior frame through a concealed internal drainage channel. Water exits vertically downward, using gravity to maintain flow direction even under high wind pressure. This anti-backflow design prevents rain from being pushed back into the frame during storms — a common failure point in standard casement windows for homes in coastal areas.

Flush Frame Design on Both Interior and Exterior

When closed, the Y109 sash and frame sit on the same plane on both the inside and outside surfaces. No part of the sash protrudes beyond the frame edge. This flush alignment produces clean, straight lines across the entire window, giving the installation a modern and minimal appearance that suits contemporary home architecture.

Built-In Corner Protectors and Anti-Theft Flyscreen

Protective caps cover every sharp corner on the sash to reduce the risk of cuts or bumps during daily use, a detail relevant in homes with children. The integrated security mesh screen uses a tamper-resistant frame that allows full airflow while forming a physical barrier against forced entry, adding a layer of protection without blocking ventilation.

Removable Child-Safety Protection

Bar

A built-in window guard bar prevents children from falling through an open sash during ventilation. The bar locks in place under normal conditions and meets child-safety protection standards. When full access is needed — for glass cleaning, an unobstructed view, or emergency exit — the bar detaches without tools and reinstalls in seconds.

Thermal Insulation — Grade 6 (U-value ≈ 2.0 W/m²·K)

The multi-chamber thermal break structure with insulating strips limits heat transfer to 2.0 W/m²·K. As energy efficient casement windows, the Y109 Series lowers heating and cooling costs compared to single-pane or non-broken-bridge alternatives.

Wind Resistance — Grade 9 (5 kPa)

The frame withstands 5,000 Pascals of pressure — equal to Category 4 hurricane force. Reinforced aluminum profiles prevent structural deformation. This grade meets building codes in Florida, Texas, and other hurricane-prone coastal regions.

Water Tightness — Grade 6 (700 Pa)

These casement aluminum windows prevent water entry under 700 Pascals of wind-driven rain. A hidden anti-backflow drainage channel routes water out before it reaches the interior seal, preventing frame corrosion and mold growth.

Air Tightness — Grade 8 (1.2 m³/m·h)

Air leakage measures just 1.2 cubic meters per meter per hour. The triple-seal system blocks dust, pollen, and temperature exchange at the sash-to-frame junction. This casement window insulation rating reduces strain on HVAC systems across seasons.

Sound Insulation — Grade 4 (35 dB)

The Y109 reduces exterior noise by 35 decibels. A 70 dB urban street drops to library-level quiet indoors. Casement windows for homes near highways or airports benefit from this sealed frame and laminated glass assembly.

Apartment

Apartments in hurricane zones face two risks: wind pressure on upper floors and air leakage between units. The Y109 Series hurricane impact casement windows use laminated glass and reinforced aluminum frames to pass ASTM E1886/E1996 large missile impact tests. The sealed casement design stops air transfer between floors, reducing HVAC load by limiting infiltration. Building owners meet Florida Building Code requirements while lowering shared energy costs per unit.

Home Office

Remote workers need a quiet, temperature-stable room to stay productive. The Y109 Series casement windows for homes use a multi-point locking system that compresses weatherstripping at every contact point. This blocks outside noise and stops air drafts around the frame. During storm season, the impact-rated laminated glass protects equipment from wind-borne debris. One window handles sound control, climate control, and storm protection together.

Hotel

Coastal hotels must protect guests during hurricanes and control room-by-room energy costs year-round. The Y109 Series hurricane impact casement windows meet High-Velocity Hurricane Zone (HVHZ) codes without adding shutters or plywood prep time. The casement aluminum windows use thermally broken frames to reduce heat transfer through the metal. Hotel operators cut per-room cooling costs and eliminate the labor cost of seasonal storm preparation.

Office Building

Commercial office buildings require windows that meet life-safety codes and support HVAC efficiency across large floor plates. The Y109 Series casement aluminum windows resist impact from wind-borne debris at speeds tested per Miami-Dade County protocols. The tight casement seal reduces unconditioned air entry, helping central systems maintain set temperatures with less output. Facility teams gain a single window system that addresses code compliance, occupant safety, and long-term energy performance in one installation.

Outdoor

Sunrooms, enclosed patios, and screened porches sit exposed to weather on three or more sides. The Y109 Series hurricane impact casement windows convert these spaces into sealed, code-compliant rooms. Each window opens fully for cross-ventilation on calm days and locks against wind loads during storms. The energy efficient casement windows maintain usable indoor temperature in these spaces without requiring a dedicated HVAC system for most climates.

Residential building

Multi-family residential buildings need uniform storm protection from ground floor to roofline. The Y109 Series casement windows for homes deliver the same impact rating and air infiltration performance on every floor. Property managers stock one frame type and one glass specification for all replacements. Consistent casement window insulation across units helps the building meet energy code benchmarks like IECC 2021 without unit-by-unit customization.

Exterior

Building exteriors must resist both direct impact and sustained wind pressure without frame failure. The Y109 Series casement aluminum windows use heavy-wall aluminum extrusions that maintain structural shape under design wind loads up to 180 mph. The narrow frame profile preserves the facade design intent while meeting hurricane glazing requirements. Architects specify one product to solve both the structural performance and the visual design challenge on exposed elevations.

Villa

Villas often feature oversized window openings that increase wind load exposure. The Y109 Series hurricane impact casement windows span wide openings while maintaining full impact and pressure ratings. Thermally broken aluminum frames reduce solar heat gain through the frame itself. Homeowners with large glass areas achieve measurable energy savings on cooling costs. The result: unobstructed views, verified storm resistance, and lower monthly utility bills in one tested window system.
