Introduction

To create the Thermal Curtain, we have chosen materials with the following properties:

-Limits incoming draughts

Inert, non-toxic, tear-proof material.

-Thermal insulation.

-Good aesthetic level.

-economic.

The milk carton contains these materials:

  • Polyethylene: (Plastic)
    • can catch fire at 260°C
    • Non-toxic and tear-proof
    • chemically inert material (does not react in any chemical or biological way)
  • Aluminium:
    • thermal insulation.
  • Cardboard and plastic limit wind currents; fewer pores than fabric.

What's more, milk cartons are economical and we recycle.

Fabric has been added for aesthetic appeal and to improve heat retention.

Matériaux

  • Milk bricks (you need more than 5 bricks to make an average curtain).
  • Fabric (more usable clothes...).


Outils

  • Thread and needle or sewing machine.
  • scissors and stapler
  • tape

Étape 1 - Preparation of Milk carton

  • Clean the remaining milk cartons thoroughly.
  • Flatten the bricks so that there are no creases.
  • Cut the brick as shown in the photo.
  • Remove the outer layer of the brick so that a little cardboard remains (be careful not to tear the brick).



Étape 2 - Grouping together the different cartons

  • Attach the different cartons (using scotch tape).
  • Staple any parts that don't fit properly.




Étape 3 - Adding fabric

You can add clothes to be thrown away or torn fabrics.

  • For aesthetics, you can add a decorative fabric to wrap the bricks and also to increase efficiency.




Étape 4 - Addition of wire for closure

  • To finish, pass a thread over the curtain to close and open it.
  • Use the thread to make a knot on one side and pull on the other to close.
