How Heat Flows Through Walls With And Without Insulation?


Fiberglass Or Glasswool:-

Fiberglass or glasswool is an insulation material made out of fibers of glass that are carefully arranged with the use of a binder in a texture that is similar to wool. It is produced from mineral fibers. Glasswool is formed through molten glass at an extremely high temperature of about 1450 degrees celcius. Fibers are spun from the melted glass. Glasswool insulation is kind of a loose filled material that is blown into walls, attics, roofs or floors. With the help of an active binder, the glasswool material is sprayed underside of the structures.

Fiberglass Insulation is made in such a way that it is compressible and it’s fibres are bonded together with high temperature binders. Thus it has thermal as well as acoustic properties. It is produced in rolls as they have different thermal or mechanical characteristics

In the process of production of glasswool, air pockets are trapped between the glass. Which results in the high properties of insulation provided by it. Since gases have poor thermal conductivity, they are trapped and make good insulation materials. That’s why glasswool insulation for roof is an ideal choice.

Glasswool is thin, light and a very warm insulation material. With a patented barrier technology, glasswool allows efficient insulation. It has properties of maximum heat retention. Glasswool is a hot insulation material made up of substances that make it the most breathable material and also makes it soundproof. It has exceptional qualities of durability and efficiency and can be easily used in mattresses or blankets making them last for a very long time. Glasswool has a number of uses ranging from insulation for roofs/walls, duvets, blankets as well as sleeping bags.


Rockwool lrb mattresses are made of rockwool which is a fibrous material formed through the process of drawing or spinning molten rock materials such as ceramics or slag. It’s conducts heat very well and make excellent insulators or absorbers of sound.

How heat flows through walls with and  without insulation?

In a wall that has no insulation, the outermost wall absorbs all the radiant heat coming from the sun and transfers it to the internal areas of home through the help of a plasterboard.

In a wall with insulation, the loss and gain of heat is much reduced. When the external walls are insulated, it means that the hot air loses all it’s energy as it circulates in the air cavity. Whatever amount of heat is left is later absorbed, all of it depends on the resistance value of the material of insulator that is installed. Only a small amount of heat passes through to keep your homes warm. In winter, this situation is reversed and cold air. It is kept outside through the same mechanism keeping your homes warm from within.

The benefits of insulation are many as they decrease electricity bills and provide natural thermal comfort. They also provide acoustic comfort as they are soundproof materials which do not let any unwanted noise transfer to the house. Insulation also provides fire protection as it is made up of non-combustible materials. Insulations helps create a healthy home with adequate insulation and better air quality. It does not allow moisture to get trapped between the walls. That’s why insulation is important for every each and every home.
