5 Reasons Why Polyisocyanurate Rigid Foam Is The First Choice

Polyisocyanurate also known as PIR or polyiso is a thermostat

plastic that is produced as a foam and used for rigid thermal

insulation. It is a development of polyurethane except for the

fact that it has much stronger thermal resistance and comes

with a lot of r- value per inch thickness than any other kind of

insulation material available on the market.

There has been much talk about its popularity, and this article

will exactly highlight the key factors as to why it is the top

choice for constructors today. www.yitac.com.sg

Polyisocyanurate rigid board brags of thermal conductivity

of 0.022 W/mK that exceeds the common 0.023 W/mK

thermal performance of PIR insulation that is offered

generally. When a couple or more layers of polyiso boards

are used to offer specified insulation thickness for a roof,

thermal bridging is dramatically minimized. To create the

most energy efficient installation in a house, the joints of the

PIR board should be offset to allow creation or reduction of

thermal loss by configuring inside out.

All kinds of insulation material before installation must meet

certain fire safety standards. Amongst all available types of

foam plastics, PIR offers the highest  level of fire resistance

due to its special configuration of strong chemical bonds that

results in high temperature resistance  up to 360oF which is

more than twice the temperature resistance offered by other

insulation materials.  

Fire Performance

Moreover, PIR doesn’t melt or drip when exposed to flame but

forms a protective surface char enhancing its fire resistance

and thus preventing firefighters from any kind of health risks.

Polyisocyanurate FoamWhen multiple layers of polyisocyanurate foam are used

to meet ASHRAE r value needs in a commercial roof

specification, there exists an opportunity to prevent

moisture on the lower side of the roof membrane. The

double layer of PIR prevents condensation that may result

from the extreme temperature from the opposite side of

the layers. This extends the life of the membrane and

prevents any other kind of accumulation beneath the

membrane thus creating a better quality built up system.www.yitac.com.sg

Prolonged Membrane Sustenance

Since multilayering of polyiso offers stronger and more

rigid surface underneath the membrane, this results in

lesser chances of cracking and splitting of water proof

membranes. Cracking usually occurs due to excessive

roof movement or loading that can lead to leakage and

need for repair and replacement. With a layered

configuration of polyisocyanurate foam insulation, there

is significant reduction in roof movement and hence, this

is less likely to occur.

Pre-insulated ductwork is very lightweight and its weight

is ver less as compared to the galvanized sheet steel

ducting. It is installed in a single fix and the requirement

for the manual logic process is negated by it.

Pre Insulated Duct

Besides, it is also less expensive as it is light-weighted.

The lightweight appearance is helpful in cost savings for

the installer and contractor. It also consumes less

space. The ductwork does not need to be insulated.
