Radiated Heat and the benefit of
Ply-Foil Multilayer Reflective Insulation

Radiated heat is the heat energy transferred in the form of electromagnetic waves, primarily from the sun.  In warm climates especially like the Caribbean, managing radiated heat is crucial to maintain comfortable indoor temperatures and improve energy efficiency. Ply-Foil multilayer reflective insulation can offer significant benefits in this regard.

Radiated heat impacts buildings by 
Direct solar radiation
The sun's rays heat up the roof and walls of a building, and
Infrared radiation
Once these surfaces are heated, they re-radiate heat into the building’s interior.

Benefits of Ply-Foil
Ply-Foil is a type of reflective insulation that consists of multiple layers of reflective aluminium foil and polyethylene bubbles which act as insulation. Here are the key benefits of using Ply-Foil to combat radiated heat:

Reflectivity

Reflects Solar Radiation
Ply-Foil insulation can reflect up to 97% of radiant heat, significantly reducing the amount of heat that penetrates the building envelope.

Lower Heat Gain
By reflecting solar radiation away from the building, it helps maintain lower indoor temperatures, reducing the need for air conditioning.

Thermal Performance

Improves R-Value
The combination of reflective layers and insulating materials improves the overall thermal resistance (R-value) of the building, enhancing its energy efficiency.

Reduces Heat Transfer
The multilayer structure minimises the transfer of heat through conduction, convection, and radiation.

Moisture and Vapor Barrier

Prevents Moisture Accumulation
Ply-Foil insulation includes a built-in vapor barrier, preventing moisture buildup within walls and roofs, which can lead to mold and structural damage.

Maintains Insulation Effectiveness
By controlling moisture, it ensures that the insulating properties of the material are not compromised over time.

Lightweight and Easy Installation

Ease of Handling
Ply-Foil insulation is lightweight and flexible, making it easier to handle and install compared to traditional bulk insulation materials.

Quick Installation
It can be installed quickly using standard tools, reducing labour costs and construction time.
