The Kana Perfect Fit Pleated Blind is a made-to-measure pleated blind sold by So Easy Blinds in 7 colours, clipping into UPVC double-glazed windows without drilling or screws. Prices start from £120.93. The defining feature here is the Perfect Fit frame: rather than fixing brackets to a wall or window reveal, the blind grips the rubber gasket on the window's inner bead, leaving the UPVC unmarked when you remove it.

Who it suits

The no-drill installation makes the Kana a natural choice for renters who cannot put holes in window frames, or for anyone reluctant to fix into new UPVC. Because the frame sits flush within the glass, the result is unusually neat - there is no visible bracket hardware, and the pleated fabric stacks cleanly when raised.

As a pleated blind, the fabric folds into a concertina as it rises rather than rolling onto a tube. That means the stack at the top is shallow and tidy, which suits smaller windows where a fat roller stack would eat into the light opening. Pleated fabric also handles awkward or narrow recess depths well, since the mechanism is slim.

The Kana is not listed with a blackout opacity rating, so you should check with So Easy Blinds before ordering it for a bedroom where full darkness is the priority. For living rooms, home offices, and any room where you want privacy and light reduction without complete blackout - such as a bathroom or kitchen with UPVC windows - the pleated format is a practical fit. The Perfect Fit frame is only compatible with UPVC windows that carry a suitable rubber gasket seal; it does not work on wooden or aluminium frames.

The colours

7 colours available

The seven finishes cover a range from neutral to distinctly bold. Perla White and Obsidian Black sit at opposite ends of the tone scale and are the most room-agnostic choices - white for maximising reflected light, black for a graphic contrast against white UPVC. Chocolate and Terra offer warmer mid-tones in brown and rust-adjacent territory, which tend to read as earthy and unobtrusive in natural light.

The remaining three finishes move into cooler or more characterful territory: Navy Blue is a deep, traditional navy, while Amethyst and Merlot introduce purple and wine tones that are less common in the pleated blind market. Those bolder options suit rooms where the blind is a deliberate accent rather than background dressing. With seven finishes the palette is compact but well-spread across warm, cool, dark, and light.

Starting at £120.93, the Kana sits in the mid-range tier for Perfect Fit pleated blinds. As with all made-to-measure products, the final price depends on your exact width and drop - larger windows cost proportionally more. The pricing grid above shows what the range costs across common window sizes so you can compare against your own measurements before ordering.

How it compares

Against a standard inside-recess pleated blind, the Kana's Perfect Fit frame costs a little more because of the clip-in mechanism, but it removes the need to measure recess depth for bracket clearance and requires no tools. If your windows are not UPVC or lack the appropriate rubber seal, a conventionally fitted pleated blind would be the alternative path - and likely cheaper.

For bedroom use where true blackout is the goal, a blackout roller blind with a closer-to-edge Perfect Fit frame or side channels would generally outperform a pleated fabric on light control. The Kana is better placed where a tidy, drill-free installation and modest light reduction are the brief rather than maximum darkness. Cellular or honeycomb blinds in a Perfect Fit format would offer better thermal insulation if that is the priority, though the colour palette options in that category are typically narrower.

Fitting and operation

The Perfect Fit frame is designed to be fitted without tools: the outer frame clips onto the rubber seal around the window's double-glazed unit, and the blind assembly then slots into that frame. Removal leaves no marks on the UPVC. One practical note - the frame is sized to your window, so accurate measurement of the glass unit (not the outer frame or recess) is important. So Easy Blinds will provide measuring guidance at the point of order; follow it carefully, because the clip-in fit depends on an exact match.
