[edit] About

It's winter, it's snowy and it's cold. We are using the heating a lot. We checked the gas meter. At an expected price point of 0.38 euros, it seems that (current state - previous state) * price => (22868 - 21640) * 0.38 = 466.64 euros, on the 4th of December. That is a lot!

The plan is to cut costs by investing in isolation. Obvious problems seem to be the roof-windows leaking heat, windows leaking heat, poor adaptability to heat one room and let the other one stay cold.

[edit] Possibilities

Please add any suggestions you can think of below. Remember: the point is to cut cost. Not to end up with the most fancy isolation system in the western hemisphere.

[edit] PU-foam (selected)

Can be used to close all open-air gaps for the roof windows

Pros:

• Easy to install

Cons:

• Messy
• Chemical
• With lots of cans, becomes pricey

Price:

• about 10 euros per can, we will need around 6

Status:

• ongoing

[edit] Door between two rooms (selected)

Should help us only heating one room and letting the other one stay cold.

Pros:

• We have already a door (thx Kurt)

Cons:

• Takes some work to install it
• Still need some wood and plugs to install it properly

Price:

•  ?

Status:

• Door installed
• Temporary bubblewrap above
• Locks down air movement well

[edit] Transparent plates

Buy see trough plates that are thick enough to trap some air (like double sided glass), and use them as a second layer to provide insulation.

Pros:

• Will probably very effective
• Lets sunlight in during day time

Cons:

• Might be a bit more expensive
• How to close the sides of the plates to prevent draft

Price:

•  ?

[edit] "Theater" cloth

Get cloth just like the black one we already have in the back and seal off all roof windows.

Pros:

• Will probably work reasonably
• Will be cheap if we can get it for free
• Easy to install and to seal

Cons:

• We might not be able to get it for free to by
• Might not work as well as we would like

Price:

•  ?

[edit] Progression

[edit] Plan

1. Get PU-foam
2. Get door installed

[edit] Action points:

• 4th December, at 14:00, gathering at the space to go shopping for PU foam and door pieces in Ledeberg =>
  • foam acquired
  • door installed
  • temporary door cover at top with bubble wrap

• 5th December, at 12:30: foaming
  • foaming done partially
  • not enough foam

• 6th December, at 20:00: new cans, continue foaming
  • new foam available, 4 cans left
  • all non-movable sides are foamed
  • some foam is cut already
  • door lock installed and half a door handle
  • todo: cutting and movable parts
  • todo: door lock needs to be replaced by other one (directionality) once we have full door handle
  • todo: door cover at top with beams

• 8th December, at 20:00: movable parts (requires roof access) and cutting excess foam
  • too tired, not done

• when?/todo: movable parts (requires roof access) and cutting excess foam
