There are three types of rigid foam board insulation.
Rigid polyisocyanurate insulation panel for walls.
Thermal performance is rated at r6 6 5 per inch but don t count on that if your winters are cold for the reasons we re about to explain.
It is used sometimes on commercial buildings for roof and wall panel insulation where it is typically sandwiched between light gauge metal.
Extruded polystyrene and polyisocyanurate unfaced or foil faced.
Pir polyiso or iso is a thermoset plastic product typically produced as a foam and used as rigid thermal insulation panel most often with aluminum foil facing.
It is less water absorbing than eps or polyiso and is used more often below grade applications under slabs foundation walls or basement walls.
One thing to note.
Product overview r matte plus 3 thermasheath 3 is rigid foam plastic thermal insulation board composed of environmentally sound closed cell polyisocyanurate foam bonded to a durable white matte non glare aluminum facer and a reflective reinforced aluminum facer.
Piping fittings valves curved side segments and many others.
Wall and ceiling overview.
By blocking thermal bridging a polyiso continuous insulation system increases the overall thermal performance of a wall assembly and a building.
Building doctors offers rigid and spray foam insulation panels for your home or business.
Has an r value of 6 5 6 8.
For more than 35 years rmax has been creating insulation solutions based on the latest building science.
Polyiso has the abnormal behavior of performing worse as the temperature gets colder.
This makes it ideal for the attic as the foil helps your home reflect rather than absorb the sun s energy creating a much cooler.
Our full line of high quality polyiso based wall and specialty insulation products for commercial residential and industrial applications deliver maximum r values and minimum environmental impact with efficiency in installation cost and design.
A polyiso continuous insulation system keeps energy and heat loss to a minimum increasing the building s energy efficiency and leading to lower monthly operating costs.
Polyisocyanurate rigid board insulation typically comes with reflective foil facing on both sides.
Ht 450 polyisocyanurate insulation ht 450 is a rigid closed cellular 2 5 nominal density polyisocyanurate that is manufactured in buns for fabrication into a variety of shapes and sizes that include but are not limited to.
The cost lies between eps and polyiso.
