MasterLine 10

Reynaers' best-insulated aluminum window platform.

Application Example

Overview

What makes the MasterLine 10
stand out.

MasterLine 10 pushes the boundaries of what aluminum windows can achieve. XPS foam insulation (0.029 W/mK) and polyamide thermal separation deliver a frame Uf of 0.94-0.99 W/m2K - the best in any Reynaers system. Four design variants (Functional, Hidden Vent, Deco, Renaissance), with the Hidden Vent achieving an 87 mm sightline where operable windows look identical to fixed panes from outside. Passive House component certification must be checked for the selected variant, glazing, size and applicable certificate.

✓

Ideal For

Ultra-low-energy residential builds, Passive House and LEED-certified projects, and high-end architect-driven homes where you need the absolute best thermal performance from an aluminum frame.

↔

Consider an Alternative When

If your energy targets are met by a 0.16 U-factor, the MasterLine 8 gives you the same Reynaers quality at a lower price. For a more budget-friendly option at similar performance, consider the Aluprof MB-86 SI+.

Provider certification describes eligible components, not every finished assembly. Confirm the actual window variant and certificate; a MasterLine 10 door certificate does not establish window certification.
