What is Rigid Foam Insulation and How is it Used?

!±8± What is Rigid Foam Insulation and How is it Used?

There are 3 types of rigid foam board insulation they are; polystyrene, polyisocyanurate and polyurethane. Each has uses they are better suited for than the others. I will talk about different type's uses and safety measures you should take when installing attic insulation. The first is polystyrene. This type of insulation uses deep heat and pressure to mold into shape. It is best used in walls and installing attic insulation. Although it is more expensive than the other two its characteristics makes it a lot stronger and more durable than the others. The second type of rigid foam insulation is bead board. It is made in such a way that bead expand to fit, producing a better insulated area. This type of insulation is often found in every day products.

Because of the bead spacing moisture is allowed to be absorbed. The third is polyisocyanurate and polyiso foam boards. Because of its strength and durability to withstand extreme temperatures it is ideal when installing attic insulation. It has a wonderful moisture barrier when it's applied with aluminum foil facing. There are some things that you need to know before using rigid foam insulation. First we will discuss flame retarder. This product takes a lot to ignite but once it does it will burn steady. It will also smolder for some time. Safety regulations require you to use flame resistant material like panel, dry wall, or gypsum wall board over the insulation.

It also deteriorates in direct sunlight so if you are installing attic insulation it needs protected with acrylic silicone, rubberized paint asphalt, roofing felt, or tar. Bugs like to make nests in the insulation so if you are insulating basement or floors it is wise to use insecticide treated insulation. Also by placing the insulation on the inside you will discourage bugs. Rigid foam insulation soaks in and traps moisture.

This could easily cause mold and wood damage. To prevent this you should use a vapor diffusion retarder especially when installing attic insulation. Of the three types of insulation; loose fill, batt and blanket and rigid foam board insulation this type has the cheapest initial start up cost. Although it can be used for many things, this product will be counter productive if installed wrong or safety precautions are not correctly taken. Before you begin installing attic insulation please read safety precautions carefully check with local building code regulations.

Solar Energy House - Warnings Regarding DIY Solar Panels

!±8± Solar Energy House - Warnings Regarding DIY Solar Panels

It you are keen to create your own Solar Energy House you may well have considered DIY solar panels. Well, while I applaud your desire to have a solar energy house, let me warn you that you will not save money by making your own solar panels. Lets look at why.

Cost of a DIY Solar Panel

Lets ignore the cost of your time. Here is a list of the materials required:
- Clear plexiglass or low iron solar glass 2ft x 4ft x 1/4in or more
- 3/4in 2ft x 4ft plywood panel
- Solar cell kit (eBay) 9, comprising:

- 50 Solar cells each 3in x 6in, 1.75w, pre-tabbed
- 10ft tabbing wire and 10ft bus wire,
- Flux pen and solder

- Peg board 2 panels 2ft x 2ft
- Clear silicone caulk/sealant
- Junction box
- Paint, stainless screws, wood for frame
- Diodes

Total cost 2. Take off for the 10 extra solar cells that are not required, gives a total of 2 for the materials to make a 60 watt solar panel. This works out at per watt.

Cost of Factory Made Panels
If you do a casual search on the Internet, most solar panels work out at - .50 per watt. But we ferreted around and found a 120watt panel for 8 retail, equivalent to .98 per watt. There are also a number of wholesalers willing to sell direct to the public, and minimum order quantities can be as low as two panels. We found a 225watt solar panel wholesale for 9 (min order 2 panels), equivalent to .44 per watt.

Warnings & Dangers of DIY Solar Panels
Also, if you are thinking about making your own solar panels to cut the cost of your solar energy house, please be aware of the following:
- In the US, you will NOT be allowed to connect your home made solar panels to the grid. If you want your solar energy house to be connected to the grid, you must use solar panels with UL certification. Many countries have similar regulations.
- Commercially manufactured solar panels come with 25 year performance guarantees. DIY solar panels have no guarantees and will probably last just a few years at best.
- With any home made solar panel there is a risk of fire from poor quality soldering. If your DIY solar panel ignited and resulted in fire damage to your house, your insurance company might be a little reluctant to pay out for a fire caused by a solar panel that did not have UL certification.
- And the final nail in the coffin of a home made solar energy house: in the US, home made solar panels will NOT qualify for the significant rebates and tax credits that are available.

If you want solar panels for your solar energy house and want a system that is safe, reliable, qualifies for rebates and will really cut your electricity bills, forget DIY. DIY can be a great introduction to understanding what it means to have a solar energy house, but it is not a viable alternative to factory made solar panels.

Make a Solar Panel as a Science or DIY Project
However, if you want to make your own solar panel as a science project, this can be fun, satisfying and very rewarding. On completion you will also have a solar panel you can show off to your friends and something you could use to provide light for a yard, shed or outbuilding.

If you want to make a solar panel as a science project, consider buying one of the "how too make solar panels" guides. Some of these are very good and do an excellent job of showing you (they have some very good videos) what to do, how to do it and when to do. Yes, a guide will add - to the cost, but that could be money very well spent, just don't fall for all the marketing hype!

Conclusion
If you want a solar energy home and to reduce your electricity bills, forget the DIY route. But, although you won't save money or reduce your electricity bill, making a solar panel as part of a science project should be very satisfying and educational. If you do not want to spend the - for one of the DIY solar panel guides, there is a lot of information on the Internet. I wish every success with your Solar Energy House.

Before you even start thinking about how you are going to build a solar panel you ought to first look over some solar energy advantages and disadvantages. Will you be taking advantage of having a solar power system, or will you be throwing away some of your time constructing one?

Advantages of Solar Power

Clean Electrical power

Since solar panels don't give off any greenhouse gases it is a very clean alternative energy source to making electricity. When you have the solar power system installed, usually on the roof of your house or on top of a business building.

Free to Use Energy

When you've got the investment of buying the equipment to build one, the price tag of having one run is practically free. And also the maintenance cost if pretty low too as well as the time, since there are no moving part involved.

Absolutely no Noise

Solar Panels are not like wind generator when it comes to producing noise. They have barely any. The only cause why they might have some sound is that they might have a tracking program were the panel turns to follow the sun to be more efficient in producing electrical power.

Endless Power source

The solar energy system uses the sun to make electrical energy, so it is basically immeasurable. The sun shines enough energy onto the earth every house to make the growth of the planet happen. And sunshine puts off move energy power than we will ever need to generate electrical power for house worldwide.

Disadvantages of Solar Energy Systems

Much is Dependent on the Weather Conditions

Solar Power systems need to be collecting the sun's energy to make electrical power, therefore the efficiency of energy production it greatly affected by what the weather conditions does. In addition, the system can only make energy if it is collecting energy from the sun, which also means that when it's dark out there will be no energy produced.

Low Cost DIY Solar Panels For Your Home

!±8± Low Cost DIY Solar Panels For Your Home

If you have decided that solar energy is the way forward then you should definitely consider DIY solar panels for your home.

When you come to look at actually installing solar power you are well aware of the benefits, but what can prove to be a stumbling block is the cost. For a full home installation the average 2007 cost in the USA was ,000 a little out of most people's leagues, I think you will agree.  

DIY solar panels can be built at a fraction of this cost, coming in at under 0 for the home build of a panel, sometimes even less than that if you follow some low cost rules. What's more they can be built with readily available tools and materials and if you get proper guidance they are something that can be done by people of all DIY abilities, some even with little DIY previous experience at all.

The key here though is going with a system that really does lay the instructions out in a step by step fashion and offers support if you have any questions.   With the savings that you will make on the installation and the ongoing savings you will make month on month on your power costs, solar panels really are something to consider in these times of economic and energy crises.

Once you have your won home based system of sustainable energy then concerns about rapidly rising electricity charges become a thing of the past. Investigate DIY solar panels for your home further and you will soon see that this is a viable solution to your energy needs.
