During the summer months, Acoustisorb, when laid horizontally as a ceiling or over purlin will reduce the downward heat flow entering by trapping the heat in the fibre. It works the same in winter by preventing the heat from leaving a building. The product retards heat flow, or slows down heat flow through the product. An important factor is thermal lag. Thermal lag means that after approximately 72 hours the heat on the one side of the product will be the same on the other. Therefore it is important to adequately ventilate the building as it will improve the performance of the product! With regards to the acoustic properties, owing to the density of the board and fibre and the softness of the material, any sound waves that approach the products behave in this manner:
|Thickness||Density||Width (M)||Length (M)||R-Value|
|25 mm||50 kg/m³||1.2 m||20 m||0.74|
|35 mm||50 kg/m³||1.2 m||10 m||1.48|
|50 mm||50 kg/m³||1.2 m||10 m||1.48|
Yes, 70% of your heat entering a building comes through the roof, and during the winter months, more than 60% of your heat loss is through your roof.
Residential applications: it assists with preventing rain, wind and hail noise from entering through the roof sheets. It also prevents noise from passing between rooms. It can also prevent noise through wooden floors.
Schools, Community Centers, Restaurants, Airports: It is very important to prevent noise passing through the roof, as the noise will affect the teaching etc. The sound that is generated in the buildings needs to be absorbed to ensure that the space is comfortable, if this is not the case you get people that will not concentrate, headaches can develop etc.
If not, why not?
If yes, what type?
Foil is not enough in isolation, it should really only be used as a vapour barrier, although it does add slightly to insulation of the building.
Thermal values of foils are only measured in R-Values. The test requires a 25mm air gap on either side of the foil. When a foil is installed on site, using a standard over purlin installation, there is no air gap and therefore the insulation value is negligible. If a foil is fixed to the rafters, below the purlins, to allow for the air gap, you will still require a vapour barrier, it will therefore be more effective to use a fiber or insulated ceiling board.
Prevents heat from entering and leaving the building, thereby moderating (keep constant) temperatures in the building. Saves Electricity, NERSA has approved the following increase in April each year, 2010 24,8%, 2011 25,8% and 2011 25,9%.
Depending on which insulation product you use, it will pay for itself between one to eight years i.e. insulated ceilings, take off the cost off normal installed ceilings and you are left with a small portion to pay off on energy savings.
It is cheaper to install insulation when constructing the building than doing it afterwards, as our products can be used as skimmed ceilings or you can use insulated bricks.
Good insulation adds a minor percentage to the building cost.
Insulation saves energy by moderating temperature in your building, which saves money on heating and cooling costs.
Makes life more pleasant and bearable.
Enables better concentration and focus.
Insulation reduces condensation in buildings, which makes them more pleasant and healthy.
Insulation products save the environment by saving energy and therefore carbon and oil.
If you are using Green products, it saves natural resources as the product is manufactured from recycled materials.
The green star rating also encompasses energy efficiency, manufacture area, if the product can easily be recycled, gases etc.
