I found some additional details in English at this site http://www.mexico-insights.com/judysblog/post/Brick-Lakesidee28099s-Cornerstone-Part-7-The-Roof.aspx. I am now following the author on Twitter and FB! I’ll have more info on waterproofing the roof ASAP. I will also be contacting the Hempcrete Pros for their suggestions in incorporating their product into this system.
See the Youtube Video of how these Spanish Masons Waterproof the Catalan Style Roofs:
In my quest to promote affordable sustainable buildings has lead me to discover a new building product that provides high R-value for energy efficiency and has the strength of concrete. Hempcrete the new miracle building material! Since this will be my retirement home, I realize that to make my limited budget go as far as possible I will need to be:
Net Zero in Energy Consumption and Energy Production and at the same time being
affordable to build on a limited budget.
Most everyone is aware that Living Trees are needed in removing the Carbon Dioxide from the Air and if you have been to the local lumber yard lately the prices of lumber needed to build a traditional stick built home can be astronomical for the average budget and until insulation is added to the structure they are not energy efficient.
This Hemp Home design I’m working with eliminates a great percentage of Lumber needed in the building process and provides the insulation that will make heating and cooling this home easy and will be affordable! This is the best of both worlds.
This Hemp Home Design is all about Sustainability and will not sacrifice the Comfort Levels that I require.
Hemp Home Design 1
The above photo is a Catalan or Boveda Vault Style Roof. When I watched this You Tube Video of the Spanish Masons in action; I realized that this was the solution to building a roof and ceiling with little to no lumber and it will be energy efficient and save me money on utility costs! The Exterior water proofing layer has not been added to the design at this stage so that the viewer can the Masonry Work that comprises the Catalan Vault Style Roof System.
Hemp Home-Water Recycling-Water Collection System
The roof also will act as a Water Collection System that allows me to capture and store Rain Water for use in the Hemp Home. When a filter is added it can also act to provide the clean water needed for cooking, cleaning, and drinking.
The CAD drawing below is option 1 for the layout and design of the Hemp Home. My girl has already pointed out that I left out: Additional Bedrooms for Visitors and a Fireplace for heat- Luckily we’re in the design stage and not in the build stage of the Hemp Home. I’m sure this floor plan will change as we narrow down our needs and must haves.
Hemp Home Room List
2 Bedrooms- 1 Master Bedroom and 1 spare bedroom
1 1/2 Baths
Mechanical Room-Water Collection Point, HVAC Air Handler, Solar Inverter, Storage, Radiant Floor Heating
Dining Room / Living Room
Kitchen with Eat In counter
NOTE: These are not my final design plans stay tuned for additions and alterations to this Hemp Home Design as well as Build Notes on how and why I’ve chosen to build my future home with Hempcrete.
The fast growing Hemp Plant will enable me to Grow and Build a Hemp Home in 2 years!
My plans are to build this home in a rural setting where I can plant and grow a field of hemp to build this home. (If we decide to build in a City Setting I will purchase the Natural Hemp Fibers). While the Hemp is growing in the first year I will build the Stone – Rock Foundation for the home. After the Hemp field has grown, harvested, and prepped for building- I can then start building the walls of the home with a move in date in year 2!
If Hemp Building isn’t a solution to replacing the lumber needed for
building an energy efficient home I don’t know what is! Scotty
This type of Vaulted Roof Building is not new- Spanish Masons have been building these type of structures for years. See Mexico Insights:

I strongly urge everyone who is involved in remodeling, retrofitting, weatherizing, or any other construction related project with a StLouis Building review and practice these must do activities when working on the typical StLouis brick or masonry building.
Improper Building or Retrofitting Techniques could lead to: Respiratory Problems, Indoor Pollution, Combustion from Natural Gas Appliances, as well as the further deterioration of your brick building.
If you are reading this I’m going to assume that you aren’t a google bot or bing bot and wear clothes in your daily activities. You are an actual human being who wears clothes.
Besides the obvious fact we wear clothes to cover our nakedness.
We humans wear clothes for protection: protection for our bodies: from the heat, from the cold, from rain and snow-summed all up from the Elements.
We protect ourselves with clothes against the Climate and Elements we live in.
Just as you wear clothes to protect yourself from the elements the various parts of a properly constructed energy efficient building are there to protect it from the elements while keeping the inhabitants comfortable.
While it may sound complex in Nature it’s really rather simple in content when talking about a Building.
The simple comparison in how warm and dryan Insulated Wind Breaker is to aSimple T-Shirt.
The Windbreakerstops theCold Airfrom reaching your skin and the Insulationis the stuff that keeps the cold from creeping close to your body.
While a T Shirt lets in both Air and Cold thus failing to keep you warm and dry. (This is the Framing of your Building. )
A Sweatshirt will help seal out a little cold but not for long. (This is the Insulation in your Building. )
But when a Windbreaker is put on over the Sweatshirt and T-Shirt it is such relief to be warm- almost anything is tolerable when in a Cold Windy Environment. (This is the Air Barrier in your Building.)
Caps or Hats (The roof of your Building see upcoming post-seeking sponsors)
Shoes and boots (The Foundation / Basement of your Building see upcoming post-seeking sponsors)
Examples 1 thru 5 when applied to a Building is your Buildings Envelope or Outer Shell.
The buildings we live and work in need protection too. Just as you will add layers against the cold to stay warm in today’s extreme climate. Your Building needs the same protection against the Elements of Heat and Cold.
The best protection against the Elements cold and heat from entering your building is: Insulation.
Insulation is your Number One Sourcefor keeping your building’s energy consumption as low as possible while staying comfortable.
Insulation keeps the Heat and Cold from creeping in your Building.
While building Insulation comes in many forms it basically performs the basic action that I mentioned above when talking about wearing a sweatshirt.
Insulation is there to keep out the heat and cold that make life uncomfortable– (to include the uncomfortable feelingyou get when you pay your local monthly Gas and Electric utility bills- for the over priced services they provide your building.)
Just as the Windbreaker stops the Wind from interfering with your body. The Air Barrier does the same for your Home or Office. Normal construction techniques have various Air Barriers All of which are designed to eliminate and reduce the cold or warm air from entering and leaving your Building. This is the second most crucial step in protecting a building against the Elements of heat and cold.
So what is the T-shirt used in this examples place in a building. The T Shirt in this example is the Buildings Walls and Roof. See the bare wall in this photo of the Benton Rehab Project
while the crew and I were rehabbing this building in St Louis. This is the framing without layers of Insulation or Air Barrier. It’s obvious that these walls will not keep out any heat or cold. Just as a t-shirt performs.
The Air Barrier and Insulation coupled with a few other areas of your building is your Buildings Envelope.

Warm air leaking into your home during the summer and out of your home during the winter and can waste a lot of your energy dollars. One of the quickest dollar-saving tasks you can do is caulk, seal, and weatherstrip all seams, cracks, and openings to the outside. You can save on your heating and cooling bill by reducing the air leaks in your home.
Hint: Use Fire Rated: 5/8″Fire Rated Drywall or Sheetrock with Fire Proof Caulking to Create the Air Tight Seal
How Does the Air Escape?
Air infiltrates into and out of your home through every hole and crack. About one-third of this air infiltrates through openings in your ceilings, walls, and floors.
First, test your home for air tightness. On a windy day, carefully hold a lit incense stick or a smoke pen next to your windows, doors, electrical boxes, plumbing fixtures, electrical outlets, ceiling fixtures, attic hatches, and other locations where there is a possible air path to the outside. If the smoke stream travels horizontally, you have located an air leak that may need caulking, sealing, or weatherstripping.
Caulk and weatherstrip doors and windows that leak air.
Caulk and seal air leaks where plumbing, ducting, or electrical wiring penetrates through walls, floors, ceilings, and soffits over cabinets.
Install foam gaskets behind outlet and switch plates on walls.
Look for dirty spots in your insulation, which often indicate holes where air leaks into and out of your house. You can seal the holes with low-expansion spray foam made for this purpose.
Look for dirty spots on your ceiling paint and carpet, which may indicate air leaks at interior wall/ceiling joints and wall/floor joists. These joints can be caulked.
Install storm windows over single-pane windows or replace them with more efficient windows, such as double-pane. See Windows on page 18 for more information.
When the fireplace is not in use, keep the flue damper tightly closed. A chimney is designed specifically for smoke to escape, so until you close it, warm air escapes—24 hours a day!
For new construction, reduce exterior wall leaks by installing house wrap, taping the joints of exterior sheathing, and comprehensively caulking and sealing the exterior walls.
Use foam sealant around larger gaps around windows, baseboards, and other places where warm air may be leaking out.
Kitchen exhaust fan covers can keep air from leaking in when the exhaust fan is not in use. The covers typically attach via magnets for ease of replacement.
Replacing existing door bottoms and thresholds with ones that have pliable sealing gaskets is a great way to eliminate conditioned air leaking out from underneath the doors.
Fireplace flues are made from metal, and over time repeated heating and cooling can cause the metal to warp or break, creating a channel for hot or cold air loss. Inflatable chimney balloons are designed to fit beneath your fireplace flue during periods of non-use. They are made from several layers of durable plastic and can be removed easily and reused hundreds of times. Should you forget to remove the balloon before making a fire, the balloon will automatically deflate within seconds of coming into contact with heat.
Sources of Air Leaks in Your Home
Areas that leak air into and out of your home cost you lots of money. Check the areas listed below.
Water and furnace flues
Electrical outlets and switches
Plumbing and utility access

Heating and cooling account for 50 to 70% of the energy used in the average American home. Inadequate insulation and air leakage are leading causes of energy waste in most homes. Insulation:
saves money and our nation’s limited energy resources
makes your house more comfortable by helping to maintain a uniform temperature throughout the house, and
makes walls, ceilings, and floors warmer in the winter and cooler in the summer.
The amount of energy you conserve will depend on several factors: your local climate; the size, shape, and construction of your house; the living habits of your family; the type and efficiency of the heating and cooling systems; and the fuel you use.
Once the energy savings have paid for the installation cost, energy conserved is money saved -saving energy will be even more important as utility rates go up.
This fact sheet will help you to understand how insulation works, what different types of insulation are available, and how much insulation makes sense for your climate. There are many other things you can do to conserve energy in your home as well. The Department of Energy offers many web sites(http://ornl.gov/sci/roofs+walls/insulation/ins_07.html) to help you save energy by sealing air leaks, selecting more energy-efficient appliances, etc.
How Insulation Works
How Insulation Works
Heat flows naturally from a warmer to a cooler space. In winter, the heat moves directly from all heated living spaces to the outdoors and to adjacent unheated attics, garages, and basements – wherever there is a difference in temperature.
During the summer, heat moves from outdoors to the house interior.
To maintain comfort, the heat lost in winter must be replaced by your heating system and the heat gained in summer must be removed by your air conditioner. Insulating ceilings, walls, and floors decreases the heating or cooling needed by providing an effective resistance to the flow of heat.
Reflective insulation or Radiant Barriers works by reducing the amount of energy that travels in the form of radiation. Some forms of reflective insulation also divide a space up into small regions to reduce air movement, or convection, but not to the same extent as batts, blankets, loose-fill, and foam.
If you have the question: Why is my house so Cold? Why are the walls so cold? Why are the outer rooms of my house so cold? Where are these cold air drafts coming from? Why is it costing me so much to heat my house? Why is my Heating Bill so high? How do I lower my heating bills? What are the recommended ways to lower my heating bills?
Answer: I’ve designed this CAD Diagram to explain how hot & cold temperature seeps into a building and vice-versa
Example: a home with 2×4 walls with 0 (zero) insulation.
You can see by the blue areas how solid materials transfer the hot/cold temperature.
Standard Minimum Code Wall Framing consisting of
Siding on Exterior of Building
1/2 in Plywood or OSB Particle Board
2×4 Framing Member Wall Stud
1/2 in Drywall or Sheet Rock
The hot/cold temperature (Blue Areas in Diagram) on the Exterior of the Building is transferred to the Interior of the Building by Conduction. This works both
The simplest explanation I can use to demonstrate and explain this is too use this example: when you are using a Metal Cooking Utensil to stir a pot of chili. If the utensil is left in the pot of chilli for any length of time. The heat will eventually transfer up the utensil handle and will usually burn your hand or fingers. Heat and Cold enter a Building in the same way; unless, there is some form of Insulation or Thermal Break to prevent the conduction of energy.
[Clicking on the Diagrams will enlarge the Photos for easier viewing.]
Example 1. Adding Insulation on the exterior of the Building normally behind the exterior wall finish. This is normally used in conjunction with Insulation in the Wall Cavities.

Example 4- Creating a Thermal Break by Adding Wall Channels

The above illustrations are just a few examples of how to prevent Energy Loss in a Building by adding: Insulation, Providing a Thermal Break, and Creating Dead Air Space. Examples 1 and 4 are used mostly in Remodeling and Renovation Projects. With examples 2 and 3 are used mainly in new construction of Buildings. For detailed information, proven scientific facts, about how energy is transferred I suggest reading the Article at Wiki on Heat Transfer at: http://en.wikipedia.org/wiki/Heat_transfer.
