A conservatory is the room people stop using. It is too hot from May to August, too cold from November to February, and too bright to watch anything on a screen in between. Blinds are the usual fix, but which blinds, and where you put them, changes the result completely. This guide covers what makes a conservatory different from a normal room, which fabric solves heat rather than glare, how blinds are fitted to uPVC without drilling, and what is worth motorising.
Why a conservatory is not just a room with big windows
A conservatory has almost no insulated surface. Walls, ceiling and doors are nearly all glass, so it gains heat faster than any other room in the house in summer and loses it faster than any other room in winter. That single fact drives every decision below: the fabric you choose, where the blinds go, and how they are fixed.
Roof blinds or side blinds: which problem are you solving?
Side blinds fix glare and privacy. Roof blinds fix temperature. If the complaint is that you cannot see a television screen, or that the neighbours can see in after dark, side blinds alone are enough. If the complaint is that the room is unusable in July, side blinds will disappoint you, because the sun is coming in overhead and no amount of fabric at eye level changes that.
A cellular blind has a honeycomb structure that traps a layer of still air against the glass, which slows heat moving in either direction. In a conservatory roof that works twice over: it holds warmth in through a Northern Irish winter and slows solar gain in summer. Reflective-backed versions push more of the sun back out before it turns into heat inside the room. Roof blinds run in side channels so they hold position on the slope rather than sagging away from the glass.
Perfect Fit blinds sit in a slim frame that clips into the gasket between the glass and the uPVC. The blind is held flush to the pane, so it moves with the door when it opens and there is nothing swinging into the frame. For conservatory doors and opening side vents that is usually the only sensible answer, and it is why Perfect Fit is so common in glazed rooms.
The honest answer on heat
No internal blind stops solar heat as effectively as blocking the sun before it reaches the glass. Once sunlight is through the pane it has already become heat inside the room, and the blind is working uphill from there. That is worth knowing before you spend money: an internal reflective cellular roof blind is the strongest practical option for most conservatories, but if the room faces due south and bakes, external shading over the glass will always out-perform it. Our guide to thermal ratings for cellular blinds explains how the insulation figures are actually measured.
- Doing the sides first is a common mistake. It is the cheaper half of the job and the half that changes the temperature least. If budget is staged, be clear which problem each stage solves.
- A roof lantern in a flat-roofed extension is a different job again, because the glass is closer to horizontal than sloped. Those are handled case by case at survey.
- Roof windows set into a tiled roof are not conservatory roofs. If that is what you have, see the roof window and VELUX blinds guide instead.

Not every blind belongs in a glazed room. These are the formats that hold up to the heat, the light and the moisture, and what each one is actually for.
Honeycomb or pleated fabric that concertinas up. The strongest internal choice for temperature, in filtering, dim-out or blackout finishes, and the standard answer for roof panels.
Best for heatA framed blind that clips into the glazing gasket. No drilling, no swinging, and it travels with the door. Available as roller, pleated or Venetian inside the frame.
Best for doorsLouvres that rotate and draw back, so a wide glazed elevation can be opened up completely. Still the most practical option for long runs and patio doors.
Best for wide spansSlats that tilt to cut glare while keeping the view. Aluminium copes with condensation and wipes clean, which makes it the safer choice near a conservatory door or a kitchen corner.
Best for damp cornersSimple, slim and available in solar-reflective fabrics that cut glare without closing the room off. A good side-panel choice where a full dress-up is not wanted.
Best for simplicityRemote, app or timer control, powered by battery, mains or solar. The obvious answer for roof panels and for opening several blinds at once.
Best for roof panelsMatch the blind to the actual complaint
People usually arrive at a showroom with one specific frustration rather than a shopping list. This is the shortest route from the complaint to the right specification.
| The problem | Where it needs treating | What usually works |
|---|---|---|
| Too hot in summer | Roof first, then sides | Reflective-backed pleated or cellular |
| Too cold in winter | Roof and all glazed sides | Cellular, closed at dusk |
| Glare on screens | Sides facing the sun | Solar-reflective roller or Venetian |
| Overlooked after dark | Sides and doors | Dim-out or blackout, Perfect Fit on doors |
| Doors that catch the blind | Opening panels only | Perfect Fit or clip fit framed blinds |
| Condensation on the glass | Coldest panels, usually low and north-facing | Aluminium Venetian or a wipeable fabric |
| Cannot reach the roof | Roof panels | Motorised, grouped on one remote |
Most conservatories end up with more than one specification: cellular in the roof, something simpler at the sides, and a framed blind on the doors. That is normal and it is how the room is quoted.
Measuring, fitting and living with them
A conservatory is measured as one job rather than as a set of separate windows, because the roof panels, the side panels and the doors all have to work together and share a colour and fabric family.
Keeping them clean
Conservatory blinds pick up more dust and more moisture than blinds anywhere else in the house. Most need only a regular dusting or a light vacuum with a brush attachment, then spot cleaning with a barely damp cloth. Pleated and cellular fabrics should not be soaked, because water sitting inside the honeycomb can leave a mark that does not come out. Aluminium Venetian slats tolerate a damp wipe well, which is exactly why they earn their place in the humid corners.
Older conservatory blinds fail in predictable ways: fabric that has faded on the sun-facing side, roof blinds that no longer hold position because the tension has gone, and clip fit frames that have loosened. None of that means the room has to be redone from scratch, and a replacement can usually be built to the existing openings even where the original supplier is long gone.
