Although many types of insulation necessitate the services of a professional installer, there are several types that can be handled by the do-it-yourself homeowner.

Insulation Types Available to the Homeowner

While shopping for insulation you need to consider the needed thickness, the R-value of the insulation and the different forms of insulation that are available to you.

The types and nature of the spaces you intend to insulate will be one determination as to the type of insulation you eventually select.

For instance, in an overhead space such as rafters, you would not use a pour-in-place insulation. You could however use insulation boards, reflective based insulation products, blanket insulation or spray-foam.

Additionally, the least expensive method to fill enclosed spaces, such as a enclosed cavity wall would be with blown-in insulation, foam-in-place insulation or pneumatically placed insulation.

If You Layer Insulation Types Take Care Not To Compress Lower Layers:

You additionally can use different types of insulation together or in combination. For example, you can use batt or blanket insulation over rigid insulation, or vise-versa.

To prevent insulation compression during layering of the insulation, place lighter types on the top, with the heaviest layers on the bottom.

By locating a heavier insulation on top of a lighter insulation product, the layer beneath will loose some of its R-value due to the compression.

The best remedy for this situation is to place a lower density loose-fill insulation over the existing loose-fill insulation, or another insulation product such as blanket insulation

Insulation Types - Blanket Insulation - Cotton

Insulation Types - Blanket Insulation:

Blanket Type Insulation: Mineral fibers from fiberglass or rock wool are used to manufacture blanket insulation.

It is available in either batts or flexible rolls. Blankets or batts are available in widths suited for standard spacing's of wall studs and attic or floor joists.

When you encounter non-standard stud or joist spacing such as wall corners, areas adjacent to windows and doors, or obstructions such as electrical devices, pipes or wires, it is a simple matter to hand-cut the blanket insulation to size. You can choose whether you will make this a do-it-yourself project, or leave it up to the professionals.

Batts are available as either unfaced, or faced with a vapor retardant barrier. If you have areas where the insulation will be left exposed, in a unfinished basement for instance, you can purchase batts with a special flame-resistant facing.

Insulation Types - Blown-in Loose Fill

Loose-fill Insulation Types- Blown-In:

Blown-In Loose Fill Insulation: Blown-in, loose fill insulation applications include rock wool, fiberglass, or cellulose forms of fiber pellets or loose fibers. They are pneumatically blown-in to walls, most frequently by professional installers. This form of insulation is frequently installed in cavity walls.

This type of insulation is additionally a common choice for filling around obstructions, unfinished attic spaces, or irregular designed areas.

When used in new home construction, the fiberglass or cellulose fibers are often mixed together with an adhesive or foam prior to spraying, to make them resistant to settling.

I would much rather utilize a product with recycled content and stay away from the fiberglass fiber products unless you can get documented information that it qualifies as an eco-friendly product, by using recycled content or natural products. Fiberglas is a know carcinogen.

Insulation Types - Soy Foam

Insulation Types: Foamed In Place

Foamed-In-Place Insulation: Foam insulation products are most often applied by professional installers. The products are mixed, metered and installed with special equipment to spray them in position.

Polyurethane and polyisocyanurate foam insulation are produced in two forms: closed-cell and open-cell.

In general, open-celled foam allows water vapor to move through the material more easily than closed-cell foam.

Open-cell foams generally exhibit better R-values for a given thickness as compared to closed-cell foams.

Insulation Types - Rigid Board Insulation

Insulation Types: Rigid Board Insulation

Rigid Board Insulation: This insulation is generally manufactured from fibrous materials or plastic foams.

It is produced in board form and molded to be used as pipe coverings.

The advantages of these products are many, including they are able to provide a greater R-value where space is limited, and there are less heat loss paths to be concerned about.

Rigid board can also be faced with reflective foils that additionally reduces the heat flow when applied next to an air space.

The most common locations for rigid board insulation is on foundation walls, beneath roofing materials and as wall sheathing.

Insulation Types - Reflective Systems

Insulation Types: Reflective Insulation Systems

Reflective Insulation Products: Reflective insulation products are fabricated from aluminum foils with a variety of backings such as kraft paper, plastic film, polyethylene bubbles, or cardboard.

This type of insulation is most efficient in the decrease of downward heat flow. Reflective systems are generally placed between roof rafters, floor joists, or wall studs.

Insulation Types - Radiant Barrier Types

Insulation Types - Radiant Barriers:

Radiant Barriers: Radiant barrier insulations are most effective at the reduction of winter heat loss, and summer heat gain.

Wood products used during new construction can be faced with a foil-facing, which when facing downward toward an attic, or other space act as an integral part of the structure.

In your search for radiant barriers look for one with a low emittance of 0.1 or less and a high reflectance of 0.9 or better.

Just about all radiant barrier types of insulation are very eco-friendly. You can even be even more eco-friendly by selection of products with recycled content.
