Materials collected so far

Hi guys

Here are the bottles I've collected so far. I should be getting more from a Bowls Club.

I've also got some timber I pulled off our garage wall that we can use to frame up the wall ready for setting the mud wall in.

Insulation through filling/painting of bottles 

A sustainable aspect of the bottle wall is the way it facilitates insulation. This is created through the use of the glass bottles.

On their own they hold few properties of insulation, however through filling the bottles with a dark liquid or material, the wall is allowed to function as a thermal mass. A saturated solution of salt and water (where no more salt will dissolve) increases the amount of heat each bottle can retain as salt raises the boiling point of water.

A further step in amplifying the wall’s ability to insulate is to paint each bottle with black enamel on one side, while painting the other side white. The black side facilitates sunlight absorption, while the white inhibits heat transmission. Both methods reinforce the notion of darker objects absorbing more heat (light).

The bottles then act as a ‘heat sink’. A heat sink can be typically linked to electronic systems, where a component is used as a passive heat exchanger, cooling the device by dissipating heat into its surrounding environment. This process is not limited to electronics however, as filled/painted bottles allow parts of the wall to absorb solar radiation during the day and radiate it back during night. This allows the bottle wall to lessen the effect of 24 hour cyclical temperature swings.

This is a great use of a recycled glass bottle wall
