Ceiling Insulation – Aerolite and Isotherm

Ceiling insulation like aerolite and isotherm become the heat flow barrier between your roof tiles and ceiling and prevents heat from passing through, keeping you cooler in summer and warmer in winter. Homes that have been well designed and insulated with insulation that meets the requirements, will give you year round comfort and will cut the cost of heating and cooling your home by nearly half which in turn reduces greenhouse gas emissions.

Climatic conditions will also influence the appropriate level and thickness needed to be installed. You will need to establish if you are trying to keep the heat in, out or both. Ceiling insulations are effective against daily temperature change as well as seasonal.

Another important factor is design technique. If ceiling insulation is installed in a place that does not have any shading or curtains thick enough to block out morning and afternoon sun, you could get a reverse effect, heat that comes in through the windows or doors can get trapped inside and create an oven effect.

Moisture problems like condensation can be eliminate by installing reflective ceiling insulation and can help assist with weather proofing your home or office. Aerolite and Isotherm ceiling insulation also have excellent sound absorption properties and is good for soundproofing a room or office. It is best to get ceiling insulation installed during construction, the new building regulations state all new homes must be insulated and achieve a curtain R-value in order to be compliant.

Ceilings, floors and roofs have a small thermal resistance on their own but not enough to be compliant with the sans 10400-xa building laws

Different climatic zones require different R-values needed to be achieved in order to be compliant with sans 10400-xa building laws

When choosing the right ceiling insulation, there are two main categories to choose from – reflective or bulk insulation. In order to get even a greater insulating affect, reflective and bulk insulations are often combined. Examples of combined insulation would be factorylite which is aerolite combined with a reflective insulation or is foil which is isotherm combined with a reflective insulation. The R-value of the product determines the products ability to resist heat flow. The higher the R-value, the better insulating affect you will get out of the product.

Bulk Insulation

Bulk insulation is excellent for resisting convected and conducted heat. Heat is trapped in pockets within the insulations structure. Thermal resistance works the same way, and it make no difference which way the heat flows through it. Bulk insulation and reflective insulation are the two types of insulations currently on the market. The Leading bulks insulations are think pink aerolite which is a glasswool product and isotherm ceiling insulation which is a polyester material. Bulk insulation comes with an R-value which differs according to which thickness of insulation you require.
