How to make sure your ceiling insulation really works

Because Aerolite is such an effective thermal barrier, it excludes heat gain in summer and retains heat within a building in winter. Heat flows naturally from a warmer to a cooler space. In winter the heat will move from all un-insulated areas to the outdoors and adjacent attics, basements etc. In summer the heat moves from outdoors to the interior.


In order for you to maximizing the efficiency of your newly installed Aerolite ceiling insulation, together with the understanding of thermal behaviour in winter and in summer, here are a few things to consider making sure that Aerolite works for you :


During cold or windy weather, too much air may enter the house. Make sure that there are no draughts in your home, seal off your windows and doors preventing cold air entering your home. In summer, open doors and windows before the sun appears allowing cool air into the house.


In winter, close your curtains when it gets dark and open during the day to allow warm air into your house.

In summer, close the curtains during the day preventing heat entering your home.


In cold areas, cut down trees that prevents the sun providing natural heat into your home.


Ensure ventilation points are not block with insulation, which includes eaves gaps and air bricks at gable ends. Proper ceiling ventilation will prevent any condensation build up and rotting of roof structure.


Because Aerolite is made of fibreglass it will absorb water. Prevent any contact with water as it will affect the insulation properties.


Turn the geyser temperature down to 60 degrees Celsius once you have installed the geyser wrap and pipe insulation.
