More thoughts on reusing plastic bottles, waxed cuboid cartons, metal cans & cardboard, for insulation & shrapnel protection

Following on from Previous experiments by Paul Ridley reusing plastic bottles, waxed cuboid cartons & cardboard over several years, mainly for packaging items & insulation, I have some more ideas.

A more urgent case for plastic reuse can be made with recent articles highlighting recycling problems, like The Big Plastic Count: Survey shows 'recycling doesn't work' 

  3 years ago, I experimented Making an Insulated Eco Brick by Filling Empty Plastic Bottles with Rolled Cardboard or Plastic & Evacuating Air (VIB))   

As the world has changed with major inflation, material shortages & european war. I believe it's time to revisit some of these ideas. Perhaps such ideas could be used in Ukraine to help protect from sharpnel while also insulating structures internally or externally from harsh winters.

I mentioned protection from projectiles on the blog post: Design method to reuse existing refugee camp tents and further insulate them from temperature / fire / projectiles at low cost

It has occurred to me that using water inside a can / bottle for thermal mass & projectile protection that has a squirt of expanding foam inside at either end to strengthen the structure & seal the water in.

Crumpled or shredded plastic /polysterene / cardboard  (see UBUNTU BLOX ) could also be used instead of water for impact 

 Fabric could be reused at either end & glued in place with the expanding foam for additional strength. I will update this blog with photos & progress shortly & welcome comments / related experiments

Evaluation of Aluminum Cans As A Thermal Insulator in Reinforced Concrete Slabs      March 2009  

"

The cost of any insulation material has the controlling rule for selection, the higher the cost,

the better the insulation and the higher the construction cost. In this study, AC was found to

meet the minimum cost requirements, since AC could be collected from Aluminum

Recycling Agencies, beside the minimal construction cost. AC may also be bought directly

from the factory for insulation use. The cost of AC is much lower than the cost of TB and the

PB

4. Conclusions:

The tested insulation materials were evaluated through models, AC showed a significant

results. Experiments also showed that the cans are a good thermal insulation material and can

withstand a considerable live and dead loads, in addition to the low construction cost and low

dead weight. From practical side of view, these cans could be packed using nylon sheets with

suitable dimensions (100x100cm or 50x50cm) for easy installation process beneath the

floor’s or ceiling’s tiles. As it was stated before that the AC recycling rate is decreasing, the

use of these cans is certainly will contribute in solving part of the environmental problems."

(PR Idea) - How about making a living fence or wall insulating panel into a bug hotel by using wood or plastic frame, containing plastic bottles or tins stuffed with cut twigs/ hay etc into,

 6 Large Rubble Bags of New Tanalised & Used Timber donated to Ellesmere Port Mens Sheds by Cabinz CIC / SAHBN  on 8-7-22

Woodwork to Wellness in Saltney was offered some as well, but they have no storage, so we are storing some wood until they have the room

 

Low Cost 2 Metre Long Composite Plastic & Fibreglass Off Cut Beams supplied to Connahs Quay Allotment for Raised Beds. Many available for £6 each in 7 colours- rot free & don't need painting.

Many available for £6 each from Saltney, contact cabinznet@gmail.com 

These are to replace rotting scaffolding boards. We can deliver locally at low cost or post larger quantites of 20+ on a pallet nationwide . 

We can supply screws and metal angle brackets to join corners at low cost

Cabinz have previously made  these panels into Green Houses  Cloche & Polytunnel Frames (Heavy duty grp fibreglass sheets available at £5 a metre)  Organic Chicken Coops  Rot Proof Shed Base & Frame

2 metre x 48mm Door edge strip (DES) Original off cut from a composite door factory, when a door blank is cut to size. Available with a colour on one side of red, dark blue, mid brown, dark brown, black, green, white.

They are similar to hardwood in weight, take screws / nails fine & do not split. They have a wood grain effect fibreglass strip either side, and moss will grow on them in time

 These beams are nailed together from smaller strips (2 are shown in the front of the picture and are available for £1 each (min. 6) ) and were part of our long term test & have already been outside for 3 years in the weather without any damage and moss grew on the outside edges.

D.I.G.R.S. (an idea by Paul Ridley to help reduce the current high energy cost and food inflation / supply issues)

 

DIVIDE- rooms with portable insulated panels, fabric or green walls to save energy & aid function 

INSULATE -walls, floors & ceilings inside. Outside use green walls of soil / water thermal mass

GROW - fruit & veg in pots inside & by outside walls for sustenance & mental / physical health

REUSE - materials to do this or use materials with recycled content to save money & resources

STORAGE in room dividers by adding insulation panels to back of  storage unit book shelves, and SECURITY SHUTTERS where insulated panels can be reused with loose pin hinges for windows to insulate and protect from rising crime

I encourage people to source preferably reusable materials locally where possible.

Cabinz cic and the Shelter and the Hardware  Bank Network (SAHBN) can supply low cost , high quality fixings such as screws, loose pin hinges & growing buckets to groups to facilitate this and possibly donate some limited amounts. As mentioned by me previously, I recommend DIY'ers exploring Hexayurt construction methods & designs

Plan to make a low cost hardware kit to allow low income groups to build locally sourced (preferably reused) panels to make foldable shelters like Hexayurts, or for childrens play dens, animals pens or room dividers to reduce heating costs and noise

 Plan to make a low cost hardware kit to allow low income groups to build locally sourced (preferably reused) panels to make shelters like Hexayurts, or childrens play dens, animal pens or room dividers to reduce heating costs and noise

  Following on from previous Experiments in Prototyping a 6' Hexayurt Shelter from  Metal Sided RIGID PIR Foam Sandwich Panels  this expands the idea to use  Loose Pin Hinges (Bzp 75mm -100mm)

 

on the corners joints instead of roof tek screws, so the hinge pins can be removed, and the shelter can be diassembled for storage / easy portability. Reusing panels for alternative uses such as window shutters for insulation / security could be explored. 

A profile / cover to seal the roof seams will have to be designed.

This panel joining system could also be used inside for other shelters such as childrens play dens, animals pens or room dividers to save heating energy, quickly stored away when unused 

An internal tensioned wire or threaded bar system to tighten structure may be required as loose pin hinge joints may need tightening. Perhaps this could be incorporated into a mezzanine in a hexayurt design 

A similar method has been used for 'removable pin split hinges as baseboard connectors'

Materials to experiment making panels for interior use:

If there is a budget:  

metal sided PIR sandwich panels (as in pic above) sips panels, mgo sips, 

recycled plastic panels (poss made by methods of www.preciousplastic.com

No budget: 

Used cardboard with edges taped to keep air inside for insulation, framed in Pallet wood, then painted using repaint project paint

Dissasemble used Furniture

We have been fortunate in aquiring several thousand of the hinges and brackets detailed below at very low cost, so we can beging to offer these hardware kits

75mm Loose Pin Hinges (100mm hinges also available)

 

 

 

Panel corners can strengthened with these Blooma Steel Fixing Clip 24mm Bracket 

 

or smaller panels can be joined together by using them in pairs fixed back to back 

 Panels from dissasembled furniture could be used like in link below and joined togethere with Blooma Steel Fixing Clip 24mm (pic above)
