Types of Attic Insulation

Keeping your home warm in cold climate is not always the easiest thing to do. One because it involves installation of a premium quality heating system and second because an unfinished attic can fail all the heating arrangements.

Thus it is significant to give proper insulation to your attic so that you can prevent significant charges on your electricity bill this season.

For all those who don’t know what insulation is, it is a material that transfers heat from one side to other! So if you don’t want to spend your winters wearing bulky sweaters then here is something for you!

Batt & Blanket Insulation:

Packed in the form of rolls, this type of insulation is done using rock wool, cotton and fiberglass. The layers can be added to this type of insulation to achieve the highest level of insulation. Those attics which have very few obstructions or penetrations can go with this type of insulation.

It is completely DIY activity and inexpensive mode of insulating attic. Rockwool is fire resistant while cotton is repellent to certain insects while fibres can irritate lungs and skin and thus you may choose the one to block airflow depending upon the requirement and budget.

Loose-Fill insulation:

As the name suggests, loose fill insulation is to fill up those nooks and crannies which are hard to access. Fiberglass or cellulose can be used in this type of insulation. It is blown into relevant corners using special equipments so that they are absorbed properly.

It is perfect for irregularly shaped areas and is heavier type of insulation which makes it very effective in low temperatures. It is best for ceilings, walls and floors too as it fill the gaps and joints.

Structured Insulated Panels:

They are generally used in new construction. Structured Insulated panels also known as SIPs are made up of lightweight foam which is placed in between unfinished walls and ceilings.

Polystyrene and polyisocyanurate are two types of SIPs which have highest R-value per inch and have built-in moisture barrier to provide perfect insulation. They are treated with insecticides before application so that pests and insects should not tunnel through them. They provide superior and uniform insulation compared to any other type of insulation.

Reflective System:

In this type of insulation foils, plastic film, cardboard or polyethylene bubbles are installed facing an enclosed air space. They don’t let the inside heat to travel outside and act as barrier for the code outside air. You can install it all by yourself and when the direction of heat transfer is downwards or upwards, radiation sheets help in spreading the overall heat uniformly.

Rigid Fibrous:

This type of insulation is done using mineral wool and fiberglass as they can withstand high temperatures. It traps air and thus makes them useful in cool climates. It is basically used for ducts in unconditioned spaces as it provides a strong reflection. They bar any outside wind to step in and don’t let the heat inside the house escape from the open spots in attic.
