Why This System

This means tighter seal tolerances and frame geometry intended for thermal expansion across a wider temperature range than Tokyo-centric products.

Field Notes

“See the Sankyo Tateyama guide for full context on cold-climate cleaning protocols for this product family. Sankyo Alumi and TOSTEM sash products at a residential level are cleaned using the same core protocol - the difference is the cold-climate pre-rinse step that matters more on Sankyo Alumi's Japan Sea coast exposure.”
