I get asked this question quite often: Does the screen come with a black back? Well, a lot of screens do, so why would people be asking this question?

 

Well, they have been “told” a black back is better, because it doesn’t let any light come through. A lot of companies don’t even bother to explain why that would be better, so let me tell you why it’s better to have no light come through the fabric.

 

How light through the back of the fabric will impact your projected image

 

The best possible home theater experience is achieved when there’s no light that can interfere with the light coming from your projector. So, light coming through the back interferes with the images, because it makes the image look washed out. That means that the colours aren’t as deep and vivid.

So your goal is to have no light coming through the back of the fabric.

 

Why a black back doesn’t solve the problem.

 

As we have seen above, the issue is not the colour of the back, but the amount of light that comes through. Some companies have cleverly marketed the black finish on the reverse side of the projection fabric as the black back that lets now light through.

 

However a very thin piece of fabric – even with a black back - can let light through. And – the right piece of fabric with 2 white sides can block out any light.

Which brings us to the question: what does have an impact on the light coming through the screen?

 

Opacity and why this is more important than the black back

 

The answer for the issue is the term opacity. When the opacity of a material is 100%, it lets through all of the light. When the opacity is 0%, it blocks out all the light.

So what we are really looking for is a material that’s 0% opaque. Because this material would black out all the light that’s not coming from the projector.  Regardless of the colour of its back.

 

No projection screen manufacturer gives opacity values, so now what?

 

How to choose the right fabric, without the right information

 

Luckily, there is a way, but it will involve some work. Failing the right info, you have to do your own research. There are 2 ways:

  1. Call your potential supplier and ask for a guarantee. They should know if the material is 0% opaque and if not, they have to find out for you.
  2. Ask your supplier a fabric sample. Take a bright torch and hold the fabric against it. If no light comes through, you should be fine. Be careful not to use a light source that becomes very hot. The material might melt!

So when you go shopping for your projection screen, you know now what to look for and how to test the material. Have fun.

Wood is a good item to be used at home. Not only that it can be used as a functional material at home but it is also good because of how it looks in your home. However, it is not right to just select any wood and use it for your project. Here are the following ways on how the properties of the woods that you can use at home so you will know the right wood for your project.

Oak is among the most popular woods chosen by people for their home improvement projects, Oak beams and oak flooring adds beauty to a project. The reason for this is that they are available in varying colours and are extremely durable for many types of projects. Cedar is another popular choice of wood for many projects. This type of wood is available from some timber suppliers, its not that expensive yet can give a durable finish to an outdoor project.

Maple is also a popular wood that people use these days. The primary reasons are its color and toughness. This will help ensure that people will have a beautiful project that will last for a very long time.

Cherry is a wood that becomes more attractive with time. Its color becomes darker as it age and gives items that it is made out of an antique finish and transforms it into an elegant piece of work no matter how old it is. Walnut is also a very attractive wood, but is slightly more durable than cherry as well as being aesthetically pleasing.

Pine wood is among the most common woods since it is cheap and a quick growing bountiful source. Aside from this, it is a softwood and does not have as much strength as the tighter grained oak. You can repaint all woods but for woods that are going to be repainted then Pine, Spruce and Poplar is a wood that you can use as it can easily absorb paint. This wood is also very easy to cut and produce many variations of furniture though due to it being a softer wood the joints tend to wear. Poplar is another type of wood that has the same paint absorption properties. These woods are also very light weight and cheaper compared to other types of wood. They are also readily available to most stores.

If you want your furniture to have carvings worked into it, a good option for this is Basswood. This is a type of hardwood and because of its grain structure it is preferred by many carvers and even wood art experts. This type of wood is well regarded by craftsmen when it comes to carving wood.

Now that you know these types of wood to be used at home, you now know the types of wood that will fit your project and even your price preference. And by checking on different stores, you will find the right ones that will give you your choice of wood at the price that you can afford.

Using Oak Beams in a property adds a character feature to a building. In the area that i live the Dorset builders around me have a tendency to work in oak, many working it while it is still green and maleable.
