Insulation tips

 Check the your attic, if the insulation is compressed, or the ceiling joist are not covered with insulation you may be wasting money.
Compressed Insulation
Insulation that is compressed will not provide its full rated R-value. The overall R-value of a wall or ceiling will be somewhat different from the R-value of the insulation itself because some heat flows around the insulation through the studs and joists. If denser, heavier insulation is installed on top of lighter insulation in an attic floor area, the overall value may be different.  If R-19 batt insulation that is sized for 6¼ inches is stuffed inside a 5½-inch wall cavity, the effectiveness is decreased.
It’s important that the insulation is properly installed to achieve the maximum R-value.
If the insulation is installed in a wall with electrical wires or plumbing pipes, the fiberglass batt insulation may be compressed.
The amount of insulation (or R-value) that is recommended by building standards will depend on the local climate and the particular location of the insulation in the house.
Thermal Bridging
Insulation in between studs in a wall does not restrict the heat flow through those studs. This heat flow is called “thermal bridging.” The overall R-value of that wall may be different from the R-value of the insulation itself. 
It is recommended that the insulation installed in an attic covers the tops of the attic floor joists.  And it is also recommended that insulation sheathing be installed on stud walls. Wood studs can transfer energy through the wall assembly. Metal studs can transfer energy much better than wood studs can. As a result, the metal wall’s overall R-value can be as low as half of the insulation’s R-value.
