Which Reynaers Systems Fit Your Project?
Reynaers systems can suit different residential goals depending on the architecture, opening size, operation, glazing, performance target, weather exposure, access requirements, and the way each space will be used.
High-Performance Homes
Reynaers’ MasterLine 8 is the strongest fit as it comes in three insulation levels, so it scales to match the exact performance target - no over- or under-building. It also provides the full envelope performance,not just thermal: a. strong water tightness (1200 Pa), b. airtightness (600Pa, with 80% air-loss reduction below class 4 max) and c. proper sound insulation. SlimWall 35 is the companion piece if the project also needs curtain walls or large glazed sections. Both systems are Passive House certified, so they pair well on a high performance build.
Passive House Projects
We recommend the same products as for the High Performance projects, M asterLine 8 for windows, MasterPatio for sliding doors and SlimWall 35 for curtain walls.
Design Led Homes
For design-led projects, Reynaers windows and doors are built to disappear into the architecture. SlimLine 38 gives you that ultra-slim, steel look window profile in three variants - Classic, ferro, or Cubic. HiFinity turns walls into near-endless glass, carrying panes up to 750kg without breaking the minimal line. And MasterPatio, a Red Dot Design Award winner, pairs seamlessly with MasterLine8 for floor-to-ceiling openings that match across the whole facade. Minimal sightlines, maximum statement.
Not Sure Which Reynaers System Fits Your Project?
Every project has different opening requirements, performance goals, architectural priorities, and glazing needs. E Windowtastic can help you narrow down the Reynaers options and identify the systems that make the most sense for your project.
Let’s Discuss Your Project →Our Glass Specification
Approach
The aluminium frame is only one part of the finished window or door. E Windowtastic considers the glazing configuration, glass type, solar heat gain, orientation, altitude, safety requirements, and project performance goals when developing the complete specification.
Glazing Matched to the Project
The appropriate glazing configuration depends on the selected AluProf system, opening size, thermal requirements, solar exposure, and project goals.
All Panes Tempered
E Windowtastic specifies tempered glass across all panes as part of its glazing approach.
Pre-Pressurized for Altitude
For higher-elevation projects, insulated glass is specified with altitude conditions in mind.
SHGC Matched to the Project
Solar heat gain is considered alongside orientation, the energy modeler, and the project’s performance goals.
Reynaers Windows & Doors FAQs
Which Reynaers system is the best fit for my project?
The best fit depends on the type and size of the opening, how you want it to operate, the project’s performance goals, exposure, glazing requirements, and architectural design.
What is the difference between SlimLine38 and MasterLine 8windows?
SlimLine38 and MasterLine 8windows?
SlimLine 38 resembles the minimal ultra-slim steel look and design. Master Line is the jack of all trades: Passive House certified with a slim sightline. Aluminum at its best.
Do all Reynaers projects use the same glass specification?
No. The glass specification should be selected around the individual project and opening. E Windowtastic typically uses triple-pane glazing, but factors such as climate, orientation, elevation, the energy model, safety requirements, solar heat gain, and how each opening is used can affect the final specification.
Why does E Windowtastic place so much importance on the glass?
Because the frame is only one part of the window. The glazing influences thermal comfort, solar heat gain, safety, sound, daylight, and how the opening responds to the project’s climate and elevation. Selecting the glass alongside the frame helps the complete window and door package align with the project’s performance goals.
Where can I find more detailed Reynaers technical information?
