Rental properties. The tenant of a property is the occupier and is responsible for paying the water charges. Landlords can provide the names of their tenants in order to prove that they are not the occupier, and Irish Water will then contact the tenants.
Radiant barrier. Radiant barrier is a radiant heat reflective insulation material. Radiant barriers (also known as reflective insulation) are a type of thermal (heat) insulations that inhibits heat transfer by thermal radiation.
Dust accumulation on the reflective surface will reduce its reflective capability. The radiant barrier should be installed in a manner to minimize dust accumulation on the reflective surface. When the sun heats a roof, it's primarily the sun's radiant energy that makes the roof hot.
