Heat covers are specially designed to act as an insulator around your light fittings.
Heat covers are specially designed shrouds that help prevent the fading in colour, rusts, dents and chips.
Downlight LEDs generate heat which must be allowed to dissipate. Heat covers serve as a shield to effectively traps the heat and provide an airtight seal to reduce heat leakage and heat loss.
Glass behind light fittings and in the plastic boards of downlights allow warm air to escape so the effectiveness of downlight insulation is reduced.
Heat covers are essential for downlights. Heat covers stop heat from escaping by filling up the gaps between the plastic board and light fittings.The prime alternative of a fire hood is to slow or stop down the passage of fire through holes cut in the ceilings where the LED downlights sit. If your LED downlights already have a fire rating then fire hoods are not required. You shouldn't use a fire hood in the absence of a fire rating on your LED downlights. Fire hood installation requires disconnecting the wires and reconnecting and fitting the hood. This will cost you more, so it is recommended you get LED downlights that are fire rated.
Putting insulation over a downlight may be an issue when it comes to safety. It is essential to know the type of downlight that is involved.
Downlights are typically are halogen and LED or integrated LEDs.You can put insulation over some downlights, though it is not often recommended. Use a down light that has been tested and trusted from a reliable source.
