Colours – What do the different colours actually look like?

We’re often asked ‘just how dark is the bronze polycarbonate colour?’

It can be quite hard to tell just off the photos, however hopefully the following information should help a little more!

If you’re really stuck, feel free to call us and you can come round and see for yourself. We can hold a sheet up to the sky and you can stand under it to see just how much light it blocks out. We can also send samples out first.

  • As a comparison, the clear sheets let 92% of light and 100% of heat through. The bronze sheets let 46% of light and 72% of heat through. So the bronze does block out 46% more light than the clear.
  • The bronze does let enough light through for you to read or work under during full daylight, however it does get noticeably darker once it gets cloudy or the sun starts going down.
  • If you’re putting sheets up on on, say, a deck or awning and there are windows below where the sheets are going, we would suggest using clear sheets. This is so they let the maximum amount of light through them and through the windows below them.
  • Note, both the bronze and clear block out 99.5% of harmful UV rays. This is because the UV protection is applied to the top side of the sheet, and has nothing to do with the colouring in the sheet.

We stock clear and bronze sheets from 2.4m up to 4.8m in our two stores. We can also get 5.4m, 6.0m and 7.2m in clear or bronze as a special order. These are for delivery only, we don’t bring them into our stores.

Grey or opal colours (which we can get as a special order)

We can also order grey or opal in any length as a special order – delivery only.

With regards to the four colours available, here is some more information:

Light transmission / Heat reduction:

  • Clear – 92% / 0%
  • Bronze – 46% / 28%
  • Grey – 24% / 39%
  • Opal – 56% / 59%

Below is a photo and a video showing all four colours:

  • Clear – pretty much 100% clear, you see a slight distortion through them but not much.
  • Bronze – blocks out just over 50% light but you can still see clouds, objects through it etc.
  • Grey – blocks out about 75% light, so darker than the bronze, and more grey rather than bronze/brown.
  • Opal – lets quite a lot of light through, you just can’t see through it. You’ll see shapes/shadows but won’t be able to make anything out.

  1. Hi, we are looking to replace our corflute conservatory roof on which the top layer has cracked and is letting dirt settle inside the channels. There are 7 sections (approx. 585mm x 2.4m long each) to be replaced and there are already aluminium channels there. Is it relatively easy to remove the existing sheets and install new ones ourselves? Could you please advise which accessories we may require? Our current roof also has rubber seals between the joinery and corflute (some have shrunk quite a lot). Do you recommend we use rubber seals once we replace it as well? Any help and advice is much appreciated. (I have a photo I can email through if it helps? Thanks so much, Rachael

    1. Hi Rachael, thanks for your enquiry 🙂 I’ve just replied by email as well.

      It shouldn’t be too difficult to replace the existing sheets yourselves. The aluminium channels may need to be taken off in order to get the new sheets in. If you’re going to use the aluminium channels again I would suggest replacing the rubber seals.

      We have a slightly different joining system which is made of polycarbonate, and has a top and bottom piece. The bottom piece gets screwed to the frame and then the sheets get put in this. The top piece of the joiner then gets clicked into the bottom piece tightly and that holds the Twinwall in place. It also means you don’t need rubber seals.

      But if you can use the existing aluminium (with new rubber seals) then that would save cost on getting new joiners.

      The other thing you’d need is sealer tape for the top edge of the Twinwall, and breathable tape for the bottom, before they’re installed.

      I hope that helps, feel free to let me know any other questions.

      Kind regards, Kurt.
