INSULATION
​
Insulation performs two functions in a roofing assembly. The obvious use is its role in reducing the heating and cooling loads on the structure. But did you know insulation plays an equally critical structural role in supporting the roofing membrane? The second and certainly every bit as important use is its function as a substrate to support the roofing membrane. In an inverted membrane assembly, the insulation is a substrate for the ballast and a protection layer for the membrane. So with so many products on the market, how do you choose the right one? There are numerous roofing insulation products on the market and as with all material products, the various insulations have their advantages and disadvantages.
​
​
The insulating value of a material is measured in terms of its"R" or"RSI" value R
being a value in imperial measurement and RSI being its metric equivalent. RSI or R
-value is a measure of a materials ability to restrict the transmission of heat and is stated
relative to the thickness of the material
The second property of insulation, its role as a substrate, is much harder to quantify
This property has many components and unfortunately for some insulation
manufacturers, the true ability of their product to perform in the role only becomes evident after several years of service. Insulation must be mechanically stable to prevent
curling and shrinking and must be strong enough to support traffic loads
insulation Properties
The properties that insulation should possess, especially if it is to be used in an exposed
membrane, warm deck roofing system are:
-
High resistance to heat flow -to reduce heat losses from the building(high"R
-
use)
-
Dimensional stability -to minimize volumetric change due to variations in temperature and moisture content. Lightweight- to minimize dead loads(loads due to the weight of structure). Shear strength -to resist deformation.
-
Impact resistance -to provide a stiff support for the membrane and resistance against indentation or puncturing
-
Durability- especially with regard to moisture(wetting and drying) and thermal cycling
-
Fire resistance-to meet Building Code requirements
-
Chemical stability -to minimize future problems with curing
-
Compatibility with other materials used in the roofing assembly
-
Surface smoothness- to provide a satisfactory surface for application of the membrane.
-
Compressive strength- to resist traffic.
