Each area is done independently because each requires a different formula.
Metal building roof rigid insulation.
Slab edge insulation is mandatory with heated slabs as required by the title 24 energy standards.
This foam can be used on either the outside or the inside of the sheathing.
Whenever the temperature between outside and i1nside your house is different the heat transfer is always there.
The cladding s attachment is then thermally isolated from the building s light gauge structure.
See the title 24 residential compliance manual for details.
Rigid board made from fiberglass would be the best option for roofs and basements as the high insulation rating allows it to insulate the home better than say loose fill or batt and blanket.
Other thickness are available.
The best material for use with metal roof insulation is in the form of foam batting.
Metals are great material as a heat conductor.
The following is a short explanation of the most basic insulation systems for metal buildings.
Insofast continuous insulation bridges across the structural framing members reducing thermal bridging even at the recessed screw attachment points.
Below is how you would determine how much insulation is needed for a 60x80x16 metal building.
They are listed in the order of ease of installation.
The insulation installs over the purlins.
60 60 80 80 280.
This is the standard 3 inch r 10 4 inch r 13 and 6 inch r 19.
Extending sheet metal flashing below grade choosing an insulation product that has a hard durable surface on one side or by other suitable means.
In fact metal roof insulation will help your home from mainly two common yet stressing things such as loss of heat and condensation.
Computing how much insulation you will need involves calculating both the perimeter wall and the roof areas separately.
So when the temperature is dropping down then water will condense on the metal panel.
This is different from the normal roll up type of insulation as it comes in panels rather than paper covered fiberglass.

It consists of open and closed cell types.
Spray foam insulation fills all the possible gaps and holes.
