Introducing the enhanced aïr 400SS Plus Aluminium Minimal Frame Sliding Door

If you already specify or install our sliding doors, you’ll be pleased to know we’ve made them even better.

The enhanced aïr 400SS Plus Aluminium Minimal Frame Sliding Door introduces improved thermal performance, an optional upstand for a seamless finished floor detail and quick-glaze beads to help speed up installation, while retaining the premium looks and proven performance you’ve come to expect.

Whether you’re working on a contemporary new build, renovation project or luxury extension, the latest enhancements have been designed to help you meet evolving Building Regulations while making specification and installation even more straightforward.

Here’s everything you need to know about the latest enhancements and what they mean for your projects.

Improved thermal performance

As Building Regulations continue to develop, thermal performance remains a key consideration when specifying aluminium glazing.

Our aïr 400SS Plus Aluminium Minimal Frame Sliding door features upgraded polyamide thermal breaks, helping the system achieve even better U-values. The system can achieve:

• U-values of 1.4 W/m²K using a 1.0 W/m²K double glazed unit
• U-values of 1.2 W/m²K using a 0.7 W/m²K triple glazed unit

These enhanced thermal properties help you specify with confidence while supporting compliance with the latest performance standards. They also provide homeowners with improved energy efficiency, helping create comfortable living spaces and potentially reducing energy consumption over the lifetime of the property.

Achieve a seamless finished floor detail

To provide even greater design flexibility, we’ve introduced an optional upstand for both 2-track and 3-track frames. This allows the finished floor level to meet the top of the outer frame, creating a cleaner, more seamless flush finish.

It’s an ideal solution for contemporary homes where uninterrupted transitions and premium detailing are an important part of the overall design.

Simpler installation

We’ve also introduced a quick-glaze pre-gasketed bead for 28mm glazed units, helping make installation quicker and more efficient.

It’s a simple enhancement that can help reduce installation time while maintaining the high-quality finish expected from our aïr range.

By making glazing quicker and more straightforward, installers can complete projects more efficiently while maintaining the exceptional build quality and attention to detail that define every Everglade Windows’ aluminium sliding door.

A straightforward transition

Although we’ve enhanced the system, we’ve deliberately kept the transition as easy as possible.

The aïr 400SS Plus retains:

• Ultra-slim 20mm and 35mm interlocking sightlines for less frame and more glass
• Configurations of up to six panels, with maximum panel sizes of 2m x 2.5m
• High-performance weather seals and impressive wind resistance
• Smooth, easy-glide operation with sash weights up to 250kg

This means you can continue specifying and installing with confidence, while benefiting from improved thermal performance and enhanced installation features.
