Insu­la­tion for Mis­souri home

Insu­la­tion in any house of Mis­souri is very impor­tant part of the heat­ing and cool­ing sys­tems of the house. It helps in increas­ing the value and com­fort of your house along with decreas­ing your cost on the fuel.

Any house which is well insu­lated will have lower costs on fuel bills due to heat­ing and cool­ing of the house than the same house which is with­out insu­la­tion. You will con­sid­er­ably find 50% decre­ment in your elec­tric bills once under­go­ing the insulation.

Amount of Insulation

The impor­tant deci­sion to be taken before insu­lat­ing the house is to deter­mine the amount of insu­la­tion required to be added in the house. The sav­ings from the fuel and the cost of insu­la­tion both opti­mizes each other. Some of the min­i­mum R-Values required for Mis­souri home insu­la­tion based on the weather of Mis­souri are as follows:

For ceil­ings R = 30,

For exte­rior walls R = 20,

For floors R = 13 and

For Unheated crawl spaces over floors R = 20

 

R-Value

R-Value is noth­ing but a sim­ple mea­sure of the resis­tance of insu­la­tion against flow of heat from the house. If the insu­la­tion has higher R-Value, than it will have a bet­ter effect on the atmos­phere inside the house. The R-Value of a mate­r­ial is addi­tive in nature. Two inches of any insu­la­tion will have the twice R-Value than the same mate­r­ial hav­ing R-Value when it is one inch thicker. Also in any sec­tion of the struc­ture of the house the R-Values of all the mate­ri­als can be added up to get the total R-Value of the insulation.

Years ago there used to be only two kinds of insu­la­tion avail­able in Mis­souri mar­ket namely the min­eral wool insu­la­tion and the fiber glass insu­la­tion. Both these mate­ri­als had a kind of sim­i­lar prop­er­ties and from that time onwards it became a prac­tice to con­sider the insu­la­tion in terms of their thick­ness. But now lots of insu­la­tion mate­ri­als are avail­able in the mar­ket with each hav­ing its own char­ac­ter­is­tics. Hence the only way to com­pare them now is through their R-Values. At the time of pur­chase of some insu­lat­ing mate­r­ial con­sider its cost on the basis of per dol­lar insu­lated material.

Insu­la­tion is to be added where you want to stop the flow of heat. Obvi­ously these places would be the exte­rior walls and the ceil­ing which is just below the attic. Also the walls between the heated and unheated rooms are also to be insu­lated such as the garage or base­ment or the store rooms in the house.

At older times when the energy costs were afford­able and the sup­ply was also plenty at that time the insu­la­tion of floor was not required strongly. Also this used to keep the base­ments warmer and com­fort­able. If you still use the base­ment fre­quently, you do not need to insu­late the floors. But if you use it rarely, it would be bet­ter to heat them up when required.

The tem­per­a­ture of the earth beneath the floor also retains some tem­per­a­ture of around 55 F. hence floor does not loose more amount of heat. Mostly the loss of heat from the floors is due to the foun­da­tion wall of the house of the cold mud near the foun­da­tion wall just out­side the house. If you have the plans of heat­ing and cool­ing the base­ment too than the masonry wall in the base­ment also needs to be well insulated.

A well insu­lated home may some times be blamed to have mois­ture prob­lems where as the real prob­lem is the poor con­struct­ing mate­ri­als used by the contractors.
