SECTION 2: KEY TECHNICAL SPECIFICATIONS The following detailed specifications define the construction, dimensions and performance of our UPVC casement window. All specifications are based on standard production settings and can be adjusted to meet the specific requirements of your project. Frame and Profile Construction: Our casement windows are manufactured using high-grade multi-chamber UPVC profiles with between three and seven internal chambers, depending on the selected profile system. The multi-chamber structure provides a series of air pockets that significantly improve thermal insulation by slowing the transfer of heat through the frame. We offer several profile systems including 58mm, 60mm, 70mm, 80mm and 88mm to suit different performance requirements and budget levels. The profiles are produced from a lead-free, calcium-zinc stabilized PVC compound that is durable, recyclable and safe for residential use. Glass and Glazing: The standard glazing configuration is double-glazed insulated glass units (IGUs) comprising two panes of glass separated by a sealed air gap. The gap is typically filled with air or, for enhanced performance, with argon gas which has lower thermal conductivity than air. We offer a wide selection of glass types including clear float glass, Low-E coated glass, tempered safety glass, laminated glass and tinted glass. The glass thickness can range from 4mm to 6mm per pane, and the air gap can be configured from 6mm to 20mm depending on your thermal and acoustic requirements. For projects requiring maximum insulation, triple glazing is also available. Profile Dimensions: The visible frame width varies by profile system, typically ranging from 58mm for standard residential applications to 88mm for high-performance commercial installations. The profile wall thickness is usually between 2.0mm and 3.0mm in critical areas to ensure structural rigidity. Internal steel reinforcement, made from galvanized steel, can be added to the profiles for projects in high wind load zones or where additional structural strength is required. Hardware and Fittings: Our casement windows are fitted with a multi-point locking system that secures the sash to the frame at multiple points along the perimeter. The locking mechanism is operated by a single ergonomic handle, providing enhanced security and a firm seal when closed. The windows are equipped with durable stainless steel friction hinges that allow smooth opening and hold the window at any desired position. All moving parts are precision-manufactured and corrosion-resistant to ensure long-term reliable operation. Sealing System: Each window features double or triple EPDM (ethylene propylene diene monomer) weather seals along the frame, sash and glass. These high-quality rubber seals provide an effective barrier against air, water and noise infiltration, contributing to the window's excellent airtightness and water tightness. The seals are designed to remain flexible over a wide temperature range, ensuring reliable performance in both hot and cold climates. Surface and Color Options: The standard surface finish is a bright, UV-stabilized white that resists fading and yellowing. For customers seeking a more distinctive appearance, we offer wood-grain lamination in a variety of finishes including oak, walnut, mahogany and teak. Custom RAL colors are also available to match specific architectural requirements. The smooth, non-porous surface is easy to clean and does not require painting or regular maintenance. Thermal Performance: The U-value of our casement windows ranges from approximately 1.1 W/m2K for standard double glazing to below 0.9 W/m2K for premium triple glazing with Low-E coatings and argon gas filling. This outstanding thermal performance helps maintain comfortable indoor temperatures, reduces energy consumption and lowers heating and cooling costs. Acoustic Performance: Depending on the glazing configuration, our casement windows can provide sound reduction of up to 35 to 40 decibels. The combination of double glazing, wide air gaps, acoustic laminated glass and dense profile chambers effectively dampens noise transmission, creating a quieter and more peaceful indoor environment. Water and Wind Resistance: Our casement windows are designed with integrated drainage channels and pressure-equalized construction to efficiently channel rainwater away from the frame. Combined with the high-quality EPDM seals, this design ensures excellent water tightness even during heavy rain and storms. The windows meet high wind resistance classes and are suitable for use in coastal areas and high-rise buildings. Size Range: Casement windows are manufactured to custom sizes to fit your specific openings. Standard production supports sizes from small 500mm x 500mm units to large windows exceeding 2000mm in width or height. For very large openings, we recommend mullion-transom combinations or multiple casement units to ensure structural integrity. SECTION 3: PRODUCT FEATURES Our UPVC casement window incorporates a comprehensive range of features that deliver exceptional performance and value.
