2 Rolls of Renshade Reflective Foil 340mm x 5m $25 (Was $39ea) + Shipping ($0 Preston VIC C&C) @ The ecoMaster Store


With summer just around the corner, I started looking for a product to block radiant heat from entering my room while still allowing some light in.

After some research, I found this product called "Renshade", a thin sheet of perforated foil that claims to offer most of the advantages of external shading but none of the drawbacks:

  • Renshade is perforated aluminium foil, cut to the size of your windows and fixed to the inside glass by Velcro spots.
  • Renshade keeps heat out - radiant heat flow is reduced by 85% while re-radiating only 3%.
  • Renshade reduces solar glare substantially but allows a far more gentle light into your home, protecting your furniture from premature fading.
  • Renshade allows views outside while ensuring internal privacy. But beware, at night, the opposite occurs, so an internal blind would be useful.
  • Renshade reduces the need for and expense of air conditioning.
  • In most cases, natural evening ventilation and ceiling fans should be enough to keep temperatures at a comfortable level.
  • Renshade is easy to install and easy to take down once summer is over. Just roll it up and store carefully until next summer.
  • Designed and manufactured in Australia.

No idea how good the product actually is, and was happy to try it out at $50.00 for 2 rolls, but was even happier when I noticed at check-out that the second roll was free!
They also offer free pick up from Preston (Vic) Tuesdays and Fridays from 8:00AM to 3:00PM

*Edit: just to clarify, it's 340mm x 5m, so depending on the area you need covering, you will likely be sticking several strips (instead of 1 continuous piece) to cover the entire window

    I have the same product, it costs 50 cents and is called tin foil.

      Do you also have a keen interest in hydroponics and stolen electricity?

  • Used ordinary 30cm wide aluminium foil from supermarket to cover most of 320mm wide x 2400 high fixed amber glass windows.

    They were a "feature" in my parent's mid-70's home. Facing North they were just an unnecessary heater in QLD climate. And looked terribly dated.
    As the room had plenty of light, blocking the orange light was not a problem & significantly reduced the heat entering the room. Barely visible from outside through the coloured glass.

    Installed about 20 years ago. Still in use. A very cost effective solution where blocking light entry was not a problem.

    Would guess this should be an effective solution where light is also needed.

      that's why this product is going on sale in Victoria! not many Victorian need it…

        not many Victorian need it??

        It gets far hotter in Vic, just lower humidity.
        This will also keep heat in in Winter, stopping loss through glass - lowering heating bills! So would be good to leave down while sun provides heat in day, & put up at night. (Few need that up North!)

    I know foil can reflect radiant heat, but I still wanted to have some visibility through the window, so foil wouldn't work.

    I've also tried:
    * reflective window film - left awful streaks of silver residue on the window on removal and was not great at keeping out the heat
    * frosted window film - didn't leave any marks, but didn't help with keeping out the heat and I couldn't see anything out the window

    I'm reluctant to get double glazing due to the high costs, so I'm really hoping Renshade would do the trick.

      Could get a similar effect at low cost by putting aluminium foil on window (BluTack works), leaving gaps to allow some light & views. Could be creative with it.

      Multix Alfoil 30cm X 10m are $3, against this $25 for similar amount on 2-4-1 special.

      • hmm.. l can't believe I never even considered leaving gaps between sheets of tin foil XD
        the 2 rolls of Renshade I ordered will only be enough to cover 1 room anyway, so I might try your suggestion in the second room and see how they compare.

        Thanks for the feedback!

        • It's worth a try for $3.

          Leaving a gap at the top (& maybe bottom) of the window will allow good light in & if the window is shaded on the outside - little heat. Also good for privacy.

          Am at the house now, looking at maintenance & upgrades. Might consider replacing the useless fixed amber glass - with insulated metal louvers. Am planting shading shrubs outside. Wouldn't have thought about it until your post.
          Still, the foil works & is much cheaper!

        • I'd suggest using foil and to let the light in, pickup meditation and get one of those "bed of nails" thing. Win win I'd say!

      • If you want to do several windows/ patio doors, try Aldi's Goliath foil- 150m x 30cm for $12.99 (on sale from 27th October)

    • This stuff is really effective. Bit ghetto but it works well and get surprising amount of visibility.

  • Is there a interstate delivery option I'm missing or us it local pickup only?

    • They do interstate delivery as well, you can check the shipping estimates at the bottom of the page in your cart

      • Thanks totally missed that.

  • What's the light reflection like on the other side though, especially if you have close neighbours - are you going to blind them?

    My laundry gets HOT in summer because I have a large sliding glass door (summer sun hits it directly) so I'm trying to work out how to reduce the heat… was thinking of tinting them :)

  • Ceramic tint i herd is good at reflecting heat…
    Might be costly though

    I used Renshade for a few years at a place with a few west facing windows. Have moved since but kept the used material - if anyone in Brisbane wants to take some/all of it to test it out for free, shoot me a message. Pick up from near Westfield Garden City.

    • Thanks quop, arranged to pick up & try the product.

  • +1

    This stuff is great. Surprising amount of vision through as well.

  • thanks, bought a pair.

  • Has someone tried to use aluminum foil and then poke thousands/millions of holes with needle?

    • I guess they didn't let you play with sharp objects in kindie!
      Used for making Christmas decorations out of paper & foil. Lit with candle or other light. Very Pretty.

  • Installed Renshade on West facing kitchen window.
    Removed as it made the room & house so dark.
