WHAT IT DOES
The smog tint cuts UV and tempers glare. Per KZM, five stars on UV blocking vs two for clear TPU panels — interior stays comfortable in afternoon sun.
Smog TPU dims the view from outside. Per KZM, four stars on privacy vs one for clear TPU. Inner panel restores full privacy at night.
Same open-zipper standard as the T-250 shelter and vestibule. Replace the fabric door with this panel in seconds — no tools, no re-pitch.
An internal panel zips over the window from inside. Daylight by day, full privacy by night — without packing up the entire door.
SMOG TPU VS CLEAR TPU
Per KZM's published comparison ratings.
UV BLOCKING
Per KZM's chart, smog TPU rates five stars on UV blocking versus two stars for clear TPU. Less fade on fabrics and gear inside the shelter.
PRIVACY
Smog tint limits the outside-in view. Per KZM, privacy rates four stars versus one for clear TPU — and the included inner panel handles night-time fully.
YELLOWING
Clear TPU yellows visibly over time. Per KZM's rating, smog TPU sees less colour shift — four stars vs one — so it stays looking right for longer.

FREQUENTLY ASKED
On the T-250 Air Shelter (K251T3T28) front or rear door, OR on the T-250 Vestibule (K251T3T30) wall panels. Same open-zipper standard on both — zip the fabric door out, zip this panel in.
No — this panel is cut to the T-250 module zipper standard only. For the Albion line, see the matching Kazmi AON Albion TPU Window (Smog) — K251T3T27.
Per KZM's comparison ratings: better UV blocking (five vs two stars), better privacy from outside (four vs one), better yellowing resistance (four vs one), and reduced interior glare and heat.
KZM discloses that during persistent or heavy rain, mesh-mount TPU zippers may see minor seepage at the zipper seam — not a defect, but expected behaviour. Most weather is fine.
All TPU yellows somewhat over years — KZM discloses this is inherent to the material. Smog TPU yellows less than clear and disguises remaining shift better thanks to the dark tint.
KZM notes TPU stiffens at very low temperatures. Handle the panel gently below roughly -10 °C / 14 °F — avoid sharp creases when cold to prevent stress whitening.
An inner panel zips over the window from inside the shelter — full privacy at night while keeping the daylight benefit during the day. No tear-down needed.
FROM THE CURATOR
"A lot of TPU-window add-ons on the market are clear plastic that yellows in two seasons and reads cheap. KZM's smog tint solves both — UV protection plus a colour that hides the inevitable material shift. The fact that the panel fits both the shelter and the vestibule is the practical part: one accessory, two installation paths. Buyers who already own the T-250 setup add this for the daylight cabin look; we restock it because the swap-in-seconds workflow actually delivers on the promise."
