What is Insulation R-Value

The principle at the base of the efficiency of the thermal insulation is that the thermal energy, or the heat, will move from the warmer to the colder areas, until an equal temperature is reached in both areas. A well-insulated separator between these two areas will slow this process down, reducing the amount of heating required for your building.  The type of insulation and how to use it must be chosen in such a way as to obtain the lowest value of the thermal transfer.

The value R is a common term when it comes to insulation and we will try to explain it in relation to the other coefficients.

There is the K value, which indicates the heat conducting capacity of a material, the Lambda (λ) value, which represents the thermal conductivity, the U value, which refers to heat transfer heat loss through a certain construction element (roof, wall or floor). When we add insulation, we want a material that loses a small amount of heat, so we will look for a lower U value. The thermal transfer is given by the R values ​​of each element of the building.

R value refers to thermal resistance - the ability of a material having a certain thickness to withstand heat transfer. So, when choosing insulation material, you should be interested in something with a high R value. Therefore, while K value refers exclusively to the material, R value refers to both the material and its thickness.

Safety conscious Pensacola roofing contractors will stop work if rain starts and so should you if you have decided to do some roof work on your own.

How to Inspect Your Roof After a Storm

Image
Storms may happen in any season and require a roof inspection, to make sure the bad weather did not cause damage. Water infiltration under the roof indicates that somewhere the roof is damaged. However, not all leaks are as obvious as you may think, as wet stains that appear on the ceiling are not necessarily exactly below the roof area that allowed the infiltration. The roof will need to be checked both inside and out. Depending on the type of roof, verify if there are displaced covering materials, cracks or uncovered spaces. In addition, check the gutters and downspouts; they must not have loose, deformed or cracked elements. The area under the eaves must also be in good shape, with no visible damage. Last but not least, pay close attention to checking the areas around skylights or dormer windows, chimneys, roof vents, solar panels mounted on roofs, satellite dishes etc., as they are generally the most vulnerable and favor most water infiltration. If you have an old roof that ha...
