For sash windows

RESPILON® Adjustable Screen is designed to fit every vertical or horizontal sash (single/double hung) window. Four modifications fit this range:

height (METRIC)width (METRIC)height (IMPERIAL)width (IMPERIAL)
26 cm 46–84 cm 10” 18–33”
38 cm 51–94 cm 15” 20–37”
50 cm 75–140 cm
60 cm 85–160 cm

Two screens = Better airflow

Smog is heavier during the winter season if you live in cold climate. When the RESPILON® Adjustable Screen is used during the summer season, there can be more demand for airflow. Airflow can be greatly increased, by placing two RESPILON® Adjustable Screens in windows situated opposite to each other. Thanks to the “chimney effect” your interior will always have plenty of fresh air while being effectively protected.

Independent test results TÜV SÜD

The chart to the right shows our RESPILON® Adjustable Screens test result from TÜV, an independent technical and testing agency in Europe showing our filtration efficiency. The upper table contains particle concentrations and the lower part of the table corresponds to the screens efficiency.

Why nano matters?

There are more ways to do a filtration media. Some producers use enectrostatically charged medium to artifficially improve filtration capabilities and airflow. This works great but for very limited time. It obviously discharges quite fast in outdoor aplication. On the other way nanomaterial is just so dense that it purely mechanically blocks what it shoud. Can't be discharged just slowly cloged (see maintanance). Nano is what matters, it makes the product really work and two outer layers serve as a protection and structural support.
