Education buildings require window solutions that support energy efficiency, occupant wellbeing and long-term reliability. SlimLine 38 HI+ provides a refined, steel-look aluminium window solution that helps architects and estates teams deliver comfortable, low-maintenance learning environments across both new-build and refurbishment projects.

The HI+ variant delivers the highest thermal performance within the SlimLine 38 range, making it suitable for projects where improved insulation, reduced heat loss and enhanced internal comfort are key considerations. With slim sightlines and a minimalist appearance, the system helps maximise natural daylight while maintaining strong performance levels.

Key benefits for education projects include:

• High-performance aluminium window system designed for energy-efficient buildings
• Enhanced thermal insulation with Uf values as low as 1.4 W/m²K and Uw values as low as 0.74 W/m²K depending on configuration*
• Slim steel-look profiles to maximise glazing and natural daylight
• Excellent acoustic performance up to 48 dB to support quieter learning environments*
• Strong air, water and wind resistance for reliable performance in demanding conditions
• Security options including PAS 24 and RC2 burglar resistance solutions*
• Durable aluminium construction suitable for busy education facilities
• Low-maintenance finishes supporting whole-life value
• Options including concealed hinges, concealed drainage and balustrade solutions for a clean architectural finish

SlimLine 38 HI+ is ideal for schools, colleges and universities looking to upgrade existing buildings or create modern, efficient learning spaces. Its combination of heritage-inspired slim framing and contemporary performance makes it particularly suited to refurbishment projects where appearance, comfort and compliance must work together.

Reynaers Aluminium supports education projects with technical expertise, specification guidance, BIM resources and performance information to help estates teams and design professionals deliver compliant, practical and future-ready solutions.

*Performance depends on size, profile combinations, glazing, hardware and infill choices. Contact Reynaers Aluminium for project-specific guidance.
