The cut foam - survey techniques

Features foam

foam - a sound- and heat-insulating material consisting of 98% of the air that is enclosed in a huge number of microscopic cells of expanded polystyrene.The widespread use of the foam due to the following properties:

• low thermal conductivity;
• not hygroscopic (moisture-resistant);
• durable and lightweight;
• durable;
• non-toxic;
• resistant to rotting;
• not digested by animals.

Polystyrene is a versatile material, so is used for thermal insulation of buildings, both outside and inside, for sound insulation with noise and shock loads, for thermal insulation such volumes as refrigerators, insulated vans and freezers, for packaging and other fields.

variety of methods - start with a more affordable

In order to insulate the walls, ceiling or something else, often have to cut large sheets of insulation.The question then arises: than cut foam ?This becomes a problem because the foam crumbles and breaks easily.Cutting foam in the home can be done in several ways, evaluate their variety.

You can cut off part of wallpapering a knife .Use a cutter for foam - cheap, silent, fast and affordable.The advantage of this method is the minimum amount of waste.The sharper the knife, the quicker and better is the material is cut.Therefore it is better to use a new sharp blade.

Note thicker than the foam, the less even can get cutting position.But this method has a drawback -. Such a knife can cut the foam thickness not exceeding 5 cm If you have a jigsaw, cutting is an ugly and uneven, debris will also be a lot.

Before you cut the foam, will have to take a longer nail file, then it will be possible to cut sheets with thickness up to 10 cm without much effort. Working with p Manual discharge saw wood - is the most common way to cut foam.You do not need any specific knowledge.

to cut the workpiece in the usual knife, it must be well sharpened.Then it needs to be heated and then we can cut.Advantages of this method - the edge melts and is clean, does not fray, minimum waste.

Exotic options cutting foam

can try to cut the foam a hot nichrome wire .To build such a device for cutting foam need wire coil and a transformer.The table should be placed at an angle of 20-60 degrees.Across the table you need to pull the wire.On the one hand rigidly fix the end and on the other - by a spring.

to both ends of the wire need to connect the wires from the transformer, which is incorporated into the grid.The following is the current file and put the insulation sheet on the desk on the wire.Due to the tilt table sheets will be fed by sliding under the influence of its own weight.

to work you need to become a bit of a red wire, but in no case may burn too much.Then the cut can turn out badly wide.When heated Nichrome wire becomes longer, so the spring should be strong.With it you can adjust the length.

Try to cut material grinder . cutting foam with your hands can also be performed using grinders and disc for metal.Use should be the thinnest disk.This method is not very convenient, especially from Bulgarian to the noise and dust will be flying in all directions.

foam can carve soldering .Using it, you can quickly and efficiently cut insulation.The end of the soldering iron is necessary to flatten with a hammer.Then, it is worn on the special part made of a metal cap blade and a fountain pen, which is fixed on the end.Then, a soldering iron is heated and can be cut sheets.

In addition, you can make not only the clean cut, but figured, that is to cut parts of various shapes.

The choice of what is best to cut the foam, depends only on your wishes.Each of these methods has the right to exist, and how best to use depends on the master.
