Understanding the Basics of House Insulation

As a homeowner, you need to consider a careful house insulation strategy. This should ensure effective ventilation and air sealing that improve the energy efficiency of your home. This, therefore, reduces the utility bills. Understand as well that there are many different kinds of insulation. Choose one for a home remodeling or new home project.

Actually, there are three essential elements that need to be implemented in the strategy. These include the type of material for insulation, location to where it is installed, and the amount needed.

Talk to a reputable builder if you will have a new home built. These specific elements will need to be included leading to a good insulation strategy. You can even more expect an efficient and comfortable home.

The Type of Insulation Material to Use

As per the material type to use, it will depend much on the climate zone and the home design. In the exterior walls, fiberglass batt is more likely advised to be used. This is indeed a good insulator as it resists the fire. This is also made from loosely matted fibers.

For your attic, a blown-in dry cellulose material is also effectively used. This is made from shredded and recycled newspaper. This has already been treated with a chemical to be fire-resistant.

In the foundation walls, a rigid fiberglass may seem a good option. This starts from the sheathing of the wall down to the bottom of the foundation wall. Concerning your slab, a rather rigid foam board is preferred. This will need to begin above the slab and 2-feet blow underneath the slab.

House insulation helps keep the soil that surrounds the slab warmer. This will keep the slab even warmer. Just consult a builder if your home still falls in the planning stage. This will be effective for you to know the right strategy to insulate your home.

Always consider insulation in the floor of an attic, in the wall between the living space and the garage, and the exterior walls. These are among the areas that really need to be prioritized.

House Insulation As A Defense Against Heat or Cold Loss

You now have known it now that house insulation is a defense against heat or cool loss. The heat passes through the roof, floor, and wall to almost about forty-five percent. For example in the summer season, the heat enters the walls and roof affecting your cooling needs.

Building codes now require insulation. This is especially true when it comes to the basement that serves as a living space. Control the moisture in these spaces although it can become a real challenge. If the basement is left not insulated, it may give away to mildew, mold, and any other issues.

Materials that can be affected by moisture like the cellulose and fiberglass batts need not be used on basement insulation. In any of these areas, basement, or just the wall, consult a professional. That is the only way that you ensure comfortable and healthy conditions.

A Well Insulated House

Having a good house insulation is not only a great way to live toward a greener ideal, but to also save yourself some money on heating and cooling bills. Increasing the thermal insulation in an existing home doesn’t have to be difficult, and the financial payoff can be substantial in the long run. It is more cost-effective to add house insulation during construction than to retrofit it after the house is finished. To properly insulate a new home, you’ll need to know where to insulate and the recommended R-values for each of those areas. Use a tool to determine where you need to insulate and the recommended R-values based on your climate, type of heating and cooling system, etc. Once you know where you need to insulate and the recommended R-values, review our information on the types of insulation to help you decide what type to use and where. Before you insulate a new home, you also need to properly air seal it and consider moisture control. When remodeling, one of the best and fastest ways to insulate is using blown-in insulation. Blown-in insulation, when installed with the dense pack technique, will offer superior air sealing. It can be installed easily, reducing the amount of preparation needed. If you’re remodeling and your wall cavities will be open, look into two-part spray foam or wet spray cellulose insulation. If you are building a new home, then there are many alternatives to choose from, including structural insulated panels, insulating concrete forms, and insulated concrete blocks. All of these materials are considered insulating materials as they are manufactured with the purpose of increasing R values on a building. If you’re building a traditional framed house, consider using advanced wall framing techniques. These techniques improve the whole-wall R-value by reducing thermal bridging and maximizing the insulated wall area.

In most climates, you will save money and energy when you build a new home or addition if you install a combination of cavity insulation and insulated sheathing. Reduce exterior wall leaks by taping the joints of exterior sheathing and caulking and sealing exterior walls. Cavity fibrous or cellulose insulation can be installed at levels up to R-15 in a 2 inch x 4 inch wall and up to R-21 in a 2 inch x 6 inch wall. R-values can be higher for foam insulation and other advanced insulation systems.

Three critical elements of house insulation strategy are:

1.    The type of insulation material to be use

2.    Where it is installed to be installed

3.    And how much is needed

If there is no upcoming work being done on the home, you will want to consider which season is best for installation. Although, if you are in a cold climate some people wait until winter, hoping that prices will become lower, the cost of insulation actually remains fairly constant throughout the year. The best option is to choose an installation time that will increase energy cost savings. If you're having a new home built, be sure to talk to your builder about these elements so that you can be assured the house insulation strategy will contribute to a comfortable, efficient home.

House Insulation – Differences in Insulating Materials

House insulation is a necessity if they are constructed in cold countries or in places where there are extremes in heat and cold climates during the year. With the extremes in climate conditions, people cannot live in their houses in comfort, whether in heat or cold conditions.

However, people are creative enough to fight off these extreme weather conditions by way of insulation. For these houses, the insulation must be in between floors (basements and crawl spaces), between ceilings and unheated attics and inside all the exterior walls of the house.

With less than adequate insulation, the heating (or cooling) energy escapes through the walls, the ceilings and any place where heat can seep in or out. To keep the energy in, and keeping the heating costs down, the house would need to have the proper insulating material to wrap it up.

Insulation

Insulation needs are usually governed by R-values, in the materials and in the projects. The R-value of a material is the heat that passes through. Higher R-value means the insulating qualities of the material is also higher.

Insulation materials are available in blankets, batts and loose-fill. These materials that are usually available to users have their own R-values. However, each of these materials has its own unique qualities different from the others.

They also have different qualities in terms of ease of installation, flammability, and others that are over and above their R-values.

Here are some of the popular ones in use these days and the things to consider when choosing them for your insulating work in your house.

Fiberglass

This is usually the number one choice among the materials these days. They usually come in batts, in rolls and in pellets used in loose fill applications. Some of its advantages are that it is relatively inexpensive, easy to install, and is fire resistant.

It can have a better material for a good vapor barrier and it is available in an unfaced variation. Some of its downsides include the fact that it can be itchy and that it develops an odor when dampened.

Rock wool

This one offers almost identical qualities of fiberglass. It has nearly the same quality ass fiberglass, including its cost and its R-value. It can also be itchy, although it does not develop a smell when dampened.

There is a third new material that has almost the same qualities as these two and it is called earthwool. It is new in the market and people have to test it to check its favorable reviews.

Cellulose

Cellulose is also fire resistant like fiberglass and rockwool. However, its R-value is higher and it does not irritate skin like the two popular materials

It comes in rolls, batts, and loose-fill. It has a fine consistency which permits its being blown-in during installations through small openings or access holes.

Urethane

Urethane is mostly known as a foam-in type of insulation material, but it is very effective when installed properly. It has a very high R-value and it is also fire resistant. For acoustic use, it also has excellent sound-absorbing qualities.

For house insulation, the market has an excellent set of choices.

House Insulation - Best Options

House insulation has always been a necessity in colder places of the world all because of the extreme nature of the climate in both hot and cold weather. This is also triggered by the fact that maintaining comfortable temperatures inside the house can be expensive, not to mention that it is an ongoing yearly energy expense.

The expenses on insulating your residence can be considered an investment knowing that it is quite hefty. The consolation is that it is a one-time expense compared to the yearly payment to keep your house in comfort.

Areas  

For some consolation, there are only a handful of places that need to be insulated in your house. Obvious examples would be the attics and the walls.

With proper insulation, the ROI on your investment would be definitely raised. The reason is that the insulation on the critical parts of your house raises its total value. 

More places

The other areas that need insulation would be your ceilings with unheated spaces, the basement walls, the floors above the vented crawl spaces, the cathedral ceilings, and the floors over unheated garages and porches.

It is also wise to include insulating such areas like the knee walls and the in-between interior walls (like the bathroom). The goal is to envelop the entire house in insulating materials.

Sampler

One example of proper insulation would be the use of fiberglass. This material can keep your house cool during the summer months and keep it warm in winter.

The technology is simply that the insulation resists the flow of heat from one place to the other. As an energy form, heat moves out of the house in winter (looking for the cool places) and flows inside during summer (which is unwanted at the time).

Added advantage

There is an additional advantage in the use of fiberglass as insulating material. It keeps out the heat while at the same time it works as a sound absorber. Installed in walls and ceilings, the material can reduce (noticeably) the transmission of unnecessary sound.

This is an advantage these days as the surrounding environment in most places is getting unnecessarily noisier. Some house owners have separate sound proofing installations on their houses.

Types

The required insulation is defined in terms of the R value. This is the resistance value of a material to heat passing through it. The higher the R-value, the greater is the material’s insulating qualities.

However, choosing the insulation material strictly on its high R-value is not entirely correct. R-values of insulation for specific houses also depend on the local climate and existing building codes. You need to familiarize on their properties.

There are also other options with regards to these insulation materials for your house as there are varieties.  You can pick out fiberglass, mineral wool, cellulose, foam or cotton.

Options on materials

There are many varieties of insulation materials that you can use – fiberglass, mineral wool, cellulose, foam and cotton. (A manufacturer has just added a new mineral wool, earthwool in its line-up.)

Choosing the materials for your house insulation needs to include such factors as thermal grades (R-value), lifetime performance, fire safety, moisture among others.
