What is MasterLine 8 HI Reynaers?MasterLine 8 HI Reynaers is a premium-class aluminium window system by Belgian manufacturer Reynaers Aluminium. It is designed for projects with high demands on thermal insulation, sound insulation and architectural aesthetics. The abbreviation HI stands for High Insulation — improved thermal performance compared to the standard range.
-
How does MasterLine 8 HI differ from the standard MasterLine 8?The HI version features improved thermal inserts and optimised profile geometry, achieving a lower frame heat transfer coefficient of Uf 1.3 W/m²K. This enables a high level of energy efficiency and compliance with strict building regulations.
-
What are the thermal insulation values of MasterLine 8 HI Reynaers?The frame heat transfer coefficient Uf is 1.3 W/m²K. With a glazing unit of Ug 0.6 W/m²K and a warm-edge spacer, the window Uw coefficient reaches 0.89 W/m²K. This meets the requirements of modern energy-efficient construction.
-
Is the MasterLine 8 HI system suitable for passive houses?Yes, combined with a high-performance glazing unit and correct installation with a thermal break, the system can be used in passive construction. Consultation with a specialist is recommended to meet the requirements of a specific passive standard.
-
What are the maximum possible construction sizes?The MasterLine 8 HI system supports large-format constructions. The maximum sash weight is up to 300 kg. Exact permissible dimensions depend on the construction type, hardware and glazing unit used. Logi24 will calculate specifications for your specific project.
-
What glazing units can be used with MasterLine 8 HI?The system supports dry glazing, silicone glazing, internal and external glazing, as well as structural silicone glazing (SSG). The glazing rebate height is 27 mm, allowing a wide range of glazing units — from standard to high-performance triple glazing.
-
How durable are Reynaers aluminium windows?The MasterLine 8 HI system has been tested to 20,000 opening/closing cycles (Class 3 per EN 12400). The aluminium profile is resistant to corrosion, deformation and UV radiation. With proper maintenance, the service life of the constructions is 40–50 years and more.
-
What colours and coatings are available for MasterLine 8 HI?Available options include RAL painting in any colour from the RAL catalogue, anodising, matt and textured coatings, as well as a dual-colour finish — with different colours inside and outside. This provides complete freedom in creating the architectural appearance of a building.
-
Is the system suitable for commercial buildings?Yes, MasterLine 8 HI Reynaers is widely used in office buildings, hotels, shopping centres and other commercial facilities. The system supports large-format constructions, integration with facade systems and provides burglar resistance class RC2–RC3.
-
What is the service life of the MasterLine 8 HI Reynaers system?With proper use and periodic maintenance, Reynaers aluminium constructions last 40–50 years and more. Aluminium does not rot, does not rust and does not lose its shape even under significant daily and seasonal temperature fluctuations.
MasterLine 8 HI Reynaers is a premium-class aluminium window system developed by Belgian manufacturer Reynaers Aluminium specifically for projects with high demands on energy efficiency, aesthetics and durability. The HI (High Insulation) index denotes high thermal insulation: the frame heat transfer coefficient Uf is 1.3 W/m²K, and with the correct choice of glazing unit, the whole window Uw coefficient reaches 0.89 W/m²K. This makes the system relevant for both modern residential construction and commercial buildings.
One of the key features of MasterLine 8 HI Reynaers is its minimalist design with narrow visible profile lines. The minimum visible width of the frame–sash assembly for inward opening is just 97 mm. This maximises the glazed area, provides abundant natural light and creates a modern architectural facade appearance. The 77 mm frame installation depth provides a balance between thermal insulation properties and visual elegance.
Thermal insulation is not the only advantage of the system. MasterLine 8 HI provides sound insulation Rw up to 46 dB, which effectively protects against external noise in an urban environment. Air permeability Class 4 (600 Pa) and water tightness E900 (900 Pa) guarantee comfort and protection against bad weather. Wind load Class C5 (2000 Pa) makes the system suitable for high-rise and coastal buildings.
Security is a critical aspect for residential and commercial buildings. MasterLine 8 HI Reynaers supports hardware of burglar resistance classes RC2 and RC3, and also complies with the British standard PAS 24. Impact resistance Class I5/E5 provides protection against accidental impacts. The system has been tested to 20,000 opening/closing cycles, confirming its durability under intensive use.
Premium-class MasterLine 8 HI aluminium windows are used in a wide range of buildings: modern private homes and villas, energy-efficient apartment buildings, office buildings, hotels, shopping centres and cultural institutions. The system supports fixed, casement, tilt-and-turn and mullion constructions, as well as solutions for panoramic, ribbon and corner glazing.
MasterLine 8 HI Reynaers panoramic aluminium windows can be finished in any RAL catalogue colour, anodised, or coated with a matt or textured finish. A dual-colour finish with different colours inside and outside is available. The aluminium profile is UV-resistant and retains its colour throughout its service life without the need for repainting.
An important advantage of the system is the wide range of glazing options. MasterLine 8 HI supports dry glazing, silicone glazing, internal and external glazing, as well as structural silicone glazing (SSG), which provides a perfectly smooth facade appearance without visible hardware.
Thermally broken MasterLine 8 HI Reynaers aluminium windows are the optimal choice for projects where thermal insulation, durability, security and modern architecture are important. Logi24 offers supply, professional installation and warranty support across Europe.
