Resin Frame FIX Window "PX Series"

What is a Brest Pair? It is a "breathing" double-glazed glass that connects the hollow layer (the layer of dry air between the glass panes) with the outside air, adjusting the air pressure inside the hollow layer and the outside air. The "Brest Pair" adjusts the air pressure inside the hollow layer and the outside air by attaching "Swiss Spacer Air" to the resin spacer of the double-glazed glass, preventing potential glass breakage caused by the expansion of the hollow layer and reducing distortion of reflected images. Additionally, the hollow layer repeatedly expands and contracts due to temperature changes around the double-glazed glass (day-night temperature differences and indoor-outdoor temperature differences), which may lead to the deterioration of the sealing material. The "Brest Pair" suppresses expansion and contraction due to temperature changes, maintaining the functionality and quality of the double-glazed glass over the long term. For more details, please refer to the double-glazed glass catalog or the special page on our official website. *Applicable to: Hi Pair, Sx Pair, Heating Pair There is no problem incorporating it into our PW-type resin fixed windows and FZU-type stainless steel fixed windows.
