WHAT IS POLYISOCYANURATE?

• It is said to be also polyiso which is a
  thermoset plastic that can be produced as a foam
  and they are used as rigid thermal insulation.
  The materials that are used in it are in the
  proportion of methylene diphenyl disocyanate
  which is higher, and they are polyester-derived.

HOW IT GET MANUFACTURED?

• The reaction between the MDI and polyol usually
  takes place at higher temperatures which were
  compared with the reaction temperature which are
  generally used for the manufacturing of PUR. At
  the temperature and in the presence of specific
  catalysts, MDI will first to react with itself,
  and then it will produce the stiff, ring molecule
  and it is a reactive intermediate polymer.

BENEFITS
Keeping the outside air away
Help in blocking the pollen, dust particles and
other contaminants
Lowering the energy use and cost
Used in both interior and exterior due to the
good design and function
Before you go for the Polyisocyanurate Rigid
Board, you need to see these things.

USES OF POLYISOCYANURATE
Used as rigid thermal insulation, and it acts as
thermal conductivity
Used for fabrication of the pre-insulated duct
heating, air conditioning systems, and
ventilation.
Used in roofing insulation and vertical walls

What Is

• Displacement Ventilation
• It is a system in which the concept of
  displacement ventilations and the air which is
  supplied is at a low temperature when it comes
  about the air. This air is said to be supplied at
  floor level, and it is directed to the occupied
  zone.

• Designing of
• VENTILATION
• When DV is applied, the ventilation rate and the
  cooling load density was ensured so that the
  cooling requirements will be aligned with the
  supply of the air systems ability which will
  offset the gain of heat. These temperature based
  design can be used to match the supply
  temperature along with the current load in the
  space.

ADVANTAGES

• It provides the better air quality which is
  mixed-flow systems.
• It got low supply velocity at its diffusers which
  means it will be a low-pressure drop.
• It can use less ductwork.
• When you are going for the Displacement
  Ventilation, you need to know about the things
  that are important.
