Specifications
1. Product Overview
The PCW70 is a multi-chamber UPVC casement window system with a 70mm structural depth and a 6-chamber profile design, engineered for high-performance residential and commercial projects. It supports double and triple glazing, making it a strong performer in thermal insulation, soundproofing and hurricane impact resistance. This system is particularly popular in European markets, where tight energy codes and demanding acoustic requirements are the norm, and it is equally suited to commercial buildings and residential houses anywhere a quieter, more energy-efficient envelope is required. Colors, glass specifications, opening configurations and hardware are fully customizable.
2. Key Performance Advantages
2.1 Excellent Soundproofing
The 6-chamber profile works with the double or triple glazed unit and multi-layer gasket sealing to break the sound transmission path. Asymmetric glazing builds can be specified to target specific frequency ranges, making PCW70 well suited to buildings near roads, railways or commercial districts.
2.2 High Thermal Insulation
Six separate air chambers in the UPVC profile reduce convection within the frame, while gas-filled and Low-E glazing options cut radiant heat transfer. The result is a significantly lower overall U-value and reduced heating and cooling demand.
2.3 Hurricane Impact Resistance
The reinforced profile and correctly specified laminated glazing allow the system to withstand high wind pressure and wind-borne debris, which is why PCW70 is frequently specified for coastal and storm-prone regions as well as for hurricane impact window projects.
2.4 Structural Strength
The frame and sash chambers are reinforced with a 1.5mm (or customized) steel liner, giving the assembly the rigidity needed for larger sash sizes and higher floors without sagging or deflection.
2.5 Air and Water Tightness
Multi-layer EPDM sealing and a coordinated drainage path keep the assembly airtight and prevent water ingress during driving rain, while allowing any infiltrated water to drain outward.
2.6 Security
The multi-point locking system secures the sash at multiple points around the frame and engages the steel reinforcement, delivering a substantially higher level of security than single-point hardware.
2.7 Durability and Low Maintenance
UPVC resists rot, rust and corrosion and requires no painting. The profile’s co-extruded surface keeps its appearance under UV exposure with nothing more than occasional cleaning.
2.8 Versatile Ventilation and Insect Control
Fixed, swing out/in, tilt-turn and awning configurations can be combined within one elevation, and a retractable screen is available for insect protection while ventilating.

4. Processing & Customization Support
We provide comprehensive OEM/ODM services to meet specific project requirements:
Precision Fabrication: CNC cutting and fusion welding for clean, sealed corner joints, with steel reinforcement inserted before welding to preserve frame geometry.
Glass Build-Up: Double and triple glazed units with Low-E coatings, argon fill, warm-edge spacers and laminated or tempered panes as required.
Surface & Color: White, Black, Grey and Bronze as standard, plus customized colors and laminated film finishes for wood grain or solid tones.
Hardware Selection: Multi-point locking systems, handles and hinges from domestic or international brands to match the project specification.
Configuration: Fixed lights, transoms, mullions, tilt-turn and awning combinations built from the same 6-chamber profile family.
5. Installation & Maintenance Guidelines
Opening Inspection: Verify the opening is level, square, plumb and clear of debris, and confirm the structural fixing points before delivery of the frames.
Frame Fixing: Position packers at the specified intervals and anchor through the reinforced zones with expansion bolts; avoid fixing directly into an unreinforced chamber.
Foam Filling: Fill the perimeter gap with high-quality expanding foam for insulation and waterproofing, then trim flush after curing.
Waterproof Sealing: Seal the external perimeter with exterior-grade silicone and confirm that drainage slots and weep holes remain clear.
Glass Installation: Use correct setting blocks and glazing gaskets so the glass never contacts the profile or steel liner directly.
Sash Adjustment: Fine-tune hinges and multi-point lock cams after installation so the sash closes evenly and the gasket compresses uniformly around the full perimeter.
Film Removal: Remove protective films promptly after installation to avoid adhesive residue from sun exposure.
Regular Cleaning: Clean frames and tracks with a soft cloth and water; lubricate hardware annually. Avoid abrasive or solvent-based cleaners.
Avoid Impact: Protect glass edges and frame corners from mechanical impact throughout the remaining construction programme.
6. FAQ
Can the size be customized?
Yes. All PCW70 windows are custom-made to fit your specific rough openings.
What makes PCW70 different from PCW60?
PCW70 uses a 6-chamber, 70mm profile and supports triple glazing, giving markedly better thermal and acoustic performance.
Is it suitable for hurricane-prone areas?
Yes. With laminated impact glazing specified, the reinforced 6-chamber profile is designed to resist high wind pressure and wind-borne debris.
Does the color fade over time?
No. The co-extruded and laminated finishes are highly resistant to UV fading.
How long is the warranty?
We typically offer 5–10 years warranty on profiles and hardware, depending on the project requirements.
Do you provide export packaging?
Yes. We use protective corners, stretch wrap, and seaworthy wooden crates or pallets to ensure safe delivery.
