Materials:
- adhesive
- velcro-type fixing system
- a thin sheet of aluminum or a thin wooden board
Instructions:
If you want to insulate your house from the inside and save energy, follow these instructions:
- Cut the aluminum sheets or wooden boards with the desired shapes and size. They can be all the same or in different shapes to create original combinations.
- Depending on the final design, cut the corks with different sizes, so that some are longer than others, or just in the same size.
- Glue the corks to aluminum or wood, both vertically and horizontally, combining the different sizes.
- Glue the aluminum or wood base (with the corks previously attached) to the wall with the help of the velcro system.
From now on, you no longer have an excuse for not opening a bottle of wine….Or two!
I HAVE YEARS OF CORKS FROM WHEN I WORKED . I SAW THE PIC OF CORKS BEHIND GLASS I THINK ITS THE IDEA I HAVE BEEN LOOKING FOR ! CAN THEY BE USED INSIDE WALLS TOO?
Thank you for your comment! It’s fantastic that you already have a collection of corks – they’re a great material for DIY projects like this.
Regarding your question about using corks inside walls for insulation, it’s worth noting that corks work best when air gaps between them are minimised. Otherwise, the insulation may not be as effective due to thermal bridging, which can lead to uneven thermal performance.
For optimal thermal insulation, corks are often ground into granules or smaller pieces to create a more homogeneous layer. There’s an inspiring initiative in Valencia called Recycled Cork that collects cork stoppers, grinds them, and repurposes them specifically for insulation and other uses. You can even check their website to find collection points if you’re interested in contributing your corks: https://recycledcork.com/.
If you’re considering using whole corks, you might also explore creative applications, such as placing them behind glass, as you mentioned, to create a decorative yet partially insulating layer. However, for full-scale wall insulation, crushed cork might be more efficient.
Best of luck with your project! Feel free to share how it turns out – we’d love to see it!
