Ideal For
Custom homes with aggressive energy targets, Passive House and near-zero-energy builds, and architect-specified residential projects where thermal performance and slim aluminum aesthetics both matter.
Consider an Alternative When
If your budget is tight and you don't need passive-house-level performance, look at the Aluprof MB-79N - similar frame depth, strong thermal values, and significantly lower cost. If you want the absolute best insulation Reynaers offers, step up to the MasterLine 10.
