Rockwool Insulation Properties

2011-10-21T01:55:00.000-07:00

I suppose that you have at least once heard about Rockwool. I would be surprised if you haven’t as this is the number one insulation company on the market. It has many years of success behind its back and keeps improving its products. There are many properties of the insulation produced by Rockwool and in this article, we will pay attention to the most important ones.
Rockwool is mainly preferred by marine, offshore and industrial buildings. However, more and more households have set their eye on their products. The main properties that make this brand so popular are: sound proof, fire resistance, water and moisture repellent etc. Those are amongst the most important features of this insulation. No wonder so many people prefer it for their homes. And if installed properly, Rockwool insulation has a long life. No more drafts and cold feet, no more worries that the kids might set your house on fire and no more sleepless nights because the neighbors are having a party. I will make you familiar with some stories of people that have discovered Rockwool insulation and which of the properties they prefer the best.

Gardening with rockwool plugs

2011-10-21T01:51:00.000-07:00

Rockwool
We placed rockwool at the end of the list because this is one of the most common choice among hydroponics gardeners due to its versatility and ease of use.
Originally, rockwool was invented for use as home and building insulation. The first hydroponic gardeners that realize the usefulness of this substance were those living in Denmark; since then, it has become commercially available for use in hydroponics in two forms: rockwool cubes and rockwool cubes. The manufacturing process is similar to that of cotton candy; once stone and sand has reached the melting point, the fibers are spun into many different sizes and shapes.
The Advantages of Rockwool As a Growing Medium
rockwool cubes come in sizes up to 36″ by 12″ by 3″ and can easily be cut into the desired shape. It is extremely porous, able to hold tremendous amounts of air and water – so should your water pump fail for any reason, whether by shutting down or providing too much water, the roots of your plants will be safe long enough for you to take corrective action.
If you prefer, you can purchase rockwool plugs as well. These are small granules that stick together quite well, so messes are avoided.
Precautions
All hydroponic supplies have their advantages as well as their drawbacks, and rockwool is no exception. It is not especially environmentally friendly; being made of rock, it does not bio-degrade, therefore care must be used in its disposal. It can also present a health hazard if improperly handled; rockwool dust in the lungs can cause silicosis. It’s important to wear a face mask with approved HEPA filter when working with rockwool.
Finally, rockwool as a very high pH level; therefore, you’ll need to amend it with some kind of acidic substance and monitor pH levels on a regular basis.
As far as growing mediums are concerned however, rockwool’s light weight and ease of use make it a fine choice for use in hydroponics. Take sensible precautions, and it can be one of the best growing mediums around.

Anne Harvester has a great deal of experience with indoor gardening. Hydroponic gardening is the way of the future. Known to some as “soil less gardening”, hydroponics are proven to grow plants 20-30% faster than their soil grown counterparts.

Excellent glass wool blanket

2011-10-11T05:23:00.000-07:00

Owing to glass wool's good performance, e.g., thin and long inner fiber, low thermal conductivity, it can stop air flowing and heat transforming. Meanwhile, it can quickly reduce the transportation of sound to make effects of insulation and sound absorption. Centrifugal glass wool is divided into glass wool boards and glass wool blanket.
It was the best material used for the insulation and sound absorption of steel structures. It mainly includes bare blanket with foil-clad covered. They are widely used in industrial plants, warehouse, public facilities, exhibition centre’s, shopping centers, cold shores and a variety of indoor playgrounds, sports grounds and other buildings.
Glass wool board is processed by putting the thermosetting binder into the glass wool, by pressing and heating, and then, by curing. They are used for insulation, ventilation and adjustment of air-conditioner in commercial industry and residential constructions. Meanwhile, they have effect of energy-saving insulation, sound-controlling and improving the indoor air quality.

Glass Wool Insulation

2011-05-26T23:39:00.000-07:00

What is glass wool?

Glass wool is an insulating material made from fiberglass, arranged into a texture

similar to wool.

Glass wool is produced in rolls, boards and pipes, with different thermal and

mechanical properties.

Manufacturing process

A process similar to baking a cake, the glass wool is “cooked” at high

temperatures matching perfectly the shape of the header and the evacuated tubes.

After the fusion of a mixture of natural sand and recycled glass at 1,450 C, the

glass that is produced is converted into fibers. Under the mechanical strength of

centrifugal the product is obtained by a binder that “cements” the fibers together.

This fiber mat is then heated to around 200 C to give it strength and stability. The

final stage involves cutting the wool and packing it in rolls, boards or pipes under very

high pressure in order to easy transport and storage.

Uses

Glass wool is used to thermal insulation, cold insulation, sound absorbing and fire

resistance for building and construction industry.

It can be a loose fill material, blown into attics, or, together with an active binder

sprayed on structures that can be used to insulation of cavity walls, steel structures,

ceilings, roofs, curtain walls as well as airconditioning ducts. It is also used to insulate

piping and for soundproofing.

Gootren glass wool features

Grade A non-flammable.

Weak alkaline (PH7.5-8.0) with centrifugal technology don’t lead to rust of steel.

Superior moisture resistance with < 0.2% moisture absorption.

Good rebound even fold.

High tear strength yet readily cut with a sharp blade.
