Two-Part uPVC Window

The Two-Part uPVC Window is the most practical and versatile window solution for kitchens, utility rooms, and any room where a compact, efficient window is required. One panel is fixed for maximum light, while the second is a fully functioning tilt-and-turn sash that gives you complete control over ventilation without compromising the security or weather performance of the window. At Dublin Blinds, we take precise measurements at your home and manage the complete supply and installation process, ensuring every window fits perfectly and performs exactly as it should from the first day.

Features & Benefits

• Tilt-and-Turn Opening System: The opening sash tilts inward from the top for secure background ventilation – safe on upper floors, rain-proof, and impossible to push fully open from outside. Turn the handle further and the sash swings fully inward like a door, giving complete access to both faces of the glass for effortless internal cleaning
• Energy-Saving Glazing: Double-glazed unit with energy-saving low-emissivity glass as standard, significantly reducing heat loss and improving your home’s thermal performance
• Multi-Chamber Profiles: Available across our S400, S500, S700, and V90 profile range – choose the chamber depth and thermal specification that suits your home and budget
• Made to Measure: Every window is manufactured to the exact millimetre measurements taken at your home during your free survey – no adaptors, no filler strips, perfect fit every time
• Zero Maintenance Frames: uPVC profiles will never rot, warp, crack, or require painting. An occasional wipe with warm soapy water is all that is needed to keep the frames pristine
• Grey Sealing Gaskets: Durable grey gaskets visually maximise the glass area and maintain a clean, consistent appearance that does not discolour over years of use
• Quality Hardware: Multi-point locking hardware with tilt-and-turn mechanism, available in chrome or similar finishes

Profile Systems Explained

Choosing the right profile system is the most important decision when ordering your new windows. The profile determines the thermal performance, structural strength, and long-term durability of the frame. Our two-part window is available in four specifications:

• S400 – 4-Chamber (58mm): Budget-friendly profile for outbuildings, garages, utility rooms, and applications where cost is the primary consideration. Solid improvement over single-glazed or aluminium alternatives
• S500 – 5-Chamber European (60mm): Mid-range European-manufactured profile. Recommended for apartments and private houses where good thermal performance is required at an accessible price point
• S700 – 6-Chamber (70mm): The most popular residential choice. Thermal resistance of 0.85 m²°C/W meets all standard building regulation requirements and delivers real energy savings in Irish conditions. Excellent cost-to-performance ratio
• V90 – Class A German (90mm): The premium specification. Six-chamber German Class A profile with a 90mm frame depth for maximum thermal insulation. The right choice for BER A-rated homes and homeowners who want the highest performance available
