Plaster with Cellulose

It would depend on where you are. In the US, I believe it is not widely accepted.

"As of 2007, papercrete lacks approval from the International Code Council. This limits its range of use within the city limits of most incorporated United States cities where building codes apply. It is not used as a load-bearing wall where building codes apply. However, its strength in model structures has been proven, and homes and small commercial buildings are being constructed. There is little or no evidence of its long-term durability at present."

Never seen it used as plaster...it is not waterproof or fireproof and needs to be coated...

Usually formed into bricks...

Makes good Fred Flintstone houses...

Good day.

The main goal of the "paper-plaster" is to decrease the Heat coming from outdoor; as in many other places, in Mexico there are a lot of poor people living in tremendous warm locations (95 °F).... in fact, here in the Center Nation the weather temperature has increased for the last 2 years.

NOT BRICKS AT ALL....I understand do not fulfill with structural requirements.

Mexico have not "Legal" requirements...limitations...restrictions for plaster.

We were study waterproof, anti-bacteria, water repellent... and still feasable.

Will like to apply this plaster up above the roof (outside) and inside wall plaster west side.

I will apreciate your opinion.

Styrofoam is the best insulation....

I am afraid styrofoam is toooo much expensive

It's free...

An endless supply.....just chop it up for your concrete mix....

The cheapest way to cool a small building is to use a double roof with an airgap....

Even using shade fabric...

Next would be an evaporative cooling device of which there are endless designs but basically requires air movement, porous media and water...

If you have a reliable wind you can even make it a passive system...

Thank you SolarEagle for your suggestion.

We have analized so many options concluding that Mexican people are not good with ANY engine operation participating in the process... beside it's more expensive.

Which technical / scientific unconvinient you find with Cellulose-Plaster ? Please

...."not good with ANY engine operation "...

Oh I don't know about that, they seem to handle a lawn mower quite well...

...ok most of them do...

It just seems like a lot of effort for very little gain...

<...it's more expensive...>

What a great way to kill a viable option.

It would be wiser to wait until all the options are available and their first order of cost-benefit analysis is in place before one chooses the "least worst" one to turn into a project.

Good day.

It's a great subject now when in west part of USA & Canada the temperature rised over 45°C.

We already resolved the "Fire problem", the "Fungus problem", "Outdoor deleterious",.. it's cheap to get access the poor people.

I still would like to now your technical oppinion to use Cellulose-Sand-Clay-Cement Mix as Plaster ???

Here in Austriathis plaster was used to cover foam isolation on building in order to achieve a fire retarding layer - but some material achieving this properties are easily washed out by rain. And it was found that this material will destroy all "green" around the building!

Have you looked at or considered straw bale construction? It is a modified post and beam type of construction, with some vertical strengthening members and straw bales stacked and plastered on their surfaces. Many structures have been built in the USA using this method, and some have been around for 40+ years.

Another building method uses a "thermal chimney" above the center of a room in a fairly dry climate zone that has wide temperature swings from day to night. The chimney is open to the outside at its top and the room at its bottom, and is made of masonry 8-12 inches (20-30 cm) thick. After sunset, the chimney is warm, so it draws air out of the room because the air in the chimney is warmed from the masonry and rises, drawing outside air into the room from other openings. By morning, the chimney has cooled but the room has also. During the day warm air around the edges of the room rises up to the chimney but is cooled by the comparatively cold masonry and then drops back into the center of the room, while the sunlight is also warming the masonry. This process repeats each day, has no fans or mechanical parts (is entirely passive), and needs virtually no maintenance. This method has been used for well over 100 years in parts of the Middle-East (Iraq, Iran, areas of India, etc.) It may work for your area.

Share your location and we may be able to give more appropriate suggestions.
