Perfect Fit® Roof Blinds: What Happened, and What Now

If you’re searching for Perfect Fit® roof blinds for your conservatory, the answer has changed. The roof version isn’t made any more.

Here’s what happened, what we fit on a conservatory roof instead, and why we don’t recommend Perfect Fit® on your windows either.

The Perfect Fit® system is best known for uPVC windows and doors. A slim frame clips into the window, and the blind sits inside it, so nothing is drilled.

There was also a roof version, sold as Perfect Fit International. It was a pleated blind built into its own frame, which clipped into the shaped bars of a conservatory roof.

Why You Can’t Buy One Now

Perfect Fit International was made by Stevens (Scotland) Ltd in Brechin. In October 2024, The Courier reported that Stevens would end production in December 2024 and cease trading on 31 December 2024.

We’ve looked for anyone else making a Perfect Fit® roof blind today, and we can’t find one. Louvolite, who own the Perfect Fit® name, now describe it for uPVC windows and doors only. You’ll still see “roof windows” listed loosely by some online retailers, but none of them offers a shaped blind for each panel of a conservatory roof.

So if a company quotes you for Perfect Fit® roof blinds, it’s worth asking exactly what they’re supplying.

What We Fit on a Conservatory Roof Instead

We fit honeycomb roof blinds, with each blind made to the shape of its own roof panel. Rectangles, triangles, sloped tops and the arrowhead at the centre of a Victorian roof are all made individually, and each blind is held taut by fine cords so it stays flat at any pitch.

Roof blinds can be motorised, but most are worked by hand with an extending pole. Unlike the blinds on your side windows, a roof blind doesn’t usually need to move every day.

What makes the biggest difference is how they’re fitted.

Some companies measure the conservatory and make the blinds to what they believe the sizes are. We don’t. Once the order is placed, we come out and fit a mounting profile all the way around the roof, top and bottom. That gives the blinds a true, solid surface to fix to, and we measure every blind off the profile once it’s up.

It means an extra visit, and it takes a little longer, because the blinds can’t be ordered until the profile is in place. Once the profile is up and measured, the blinds take around 10 to 12 weeks to make, and then we come back to fit them. In our experience it’s the most accurate way to fit a conservatory roof.

Why We Only Use Translucent Fabrics on a Roof

A conservatory roof takes the full force of the sun. If a blind traps that heat against the glass, it puts the glass under stress. So on a roof we only use translucent fabrics, Duette® Unicasa and Elan, which soften the daylight rather than shut it out.

We also leave a small gap between each blind and its neighbour, so warm air can escape at the top. Where a panel tapers to a point, the blind stops a little short of it and leaves a small triangle of open glass. That’s normal, and it’s part of fitting a roof blind properly.

What About Perfect Fit® on Windows and Doors?

Perfect Fit® blinds for vertical glass are still made, and they’re in our range. But we don’t recommend them, for exactly the same reason we don’t recommend Perfect Fit® shutters.

To hold the frame in place, brackets are forced in between the rubber glazing gasket and the glass itself. That gasket is part of the seal that keeps your sealed unit dry.

Most glazing warranties exclude problems caused by anything fitted to the window afterwards. If a sealed unit mists up a few years later, brackets sitting in the gasket are an easy thing for a window company to point at, whether or not they caused it.

If you want a blind that fits to the glass without drilling, we’d point you towards TruFit. It bonds to the face of the glass on slim profiles, so nothing goes behind the gasket and the sealed unit is never touched. It also moves with the sash, so it suits tilt and turn windows.

The Short Version

The Perfect Fit® conservatory roof blind (Perfect Fit International) is no longer made. Its maker, Stevens (Scotland), ceased trading at the end of 2024.
We fit honeycomb roof blinds made to the shape of each panel, fixed to a mounting profile and measured off it.
On a roof we only use translucent fabrics, with gaps left for warm air to escape.
Perfect Fit® for windows is in our range, but we don’t recommend it, because its brackets are forced between the gasket and the glass.
For no-drill blinds on vertical glass, TruFit bonds to the face of the glass instead.

Frequently asked questions

Are Perfect Fit® roof blinds still available? No. The roof version, Perfect Fit International, was made by Stevens (Scotland) in Brechin, which ceased trading on 31 December 2024. We haven’t been able to find anyone making a Perfect Fit® roof blind since, and Louvolite now describes Perfect Fit® for windows and doors only.

What is the best alternative to Perfect Fit® roof blinds for a conservatory? Honeycomb roof blinds made to the shape of each roof panel, held taut by fine cords. We fit them to a mounting profile around the roof and measure each blind off the profile, which gives a very accurate result on Victorian and other shaped roofs.

Can you put room darkening blinds on a conservatory roof? We don’t recommend it. A roof blind that traps heat against the glass puts the glass under stress, so we only use translucent fabrics on a roof and leave gaps for warm air to escape.

Do Perfect Fit® blinds affect my window warranty? It depends on your window manufacturer’s terms, so check them first. Perfect Fit® brackets are forced between the glazing gasket and the glass, and most glazing warranties exclude problems caused by anything fitted to the window afterwards.

How long do conservatory roof blinds take? There are two visits. We fit the mounting profile first, at a date that depends on the diary, and measure every blind off it. From there the blinds take around 10 to 12 weeks to make, and then we come back to fit them.
