Frequently Asked Questions
How much energy is lost through my ceiling?
A regular home loses up to 35% of its energy through the ceiling in winter and gains a similar amount in summer.
Aerolite has a range of thicknesses that will save energy and reduce your electricity costs, offering a payback in less than 2 years with continued savings thereafter.
How is the performance of the ceiling insulation measured?
All bulk insulation materials have a Thermal Resistance or R value which is a measure of their performance. The thermal resistance, R-value is the ability of the insulation to resist the transfer of energy in the form of heat and is the most important factor when selecting insulation. The higher the R-value the more effective the insulation.
The R-value should be visibly displayed on the packaging. When purchasing ceiling insulation, compare R-values and ensure that you are getting the best “R-value” for your money. Aerolite meets your R-value requirements with a range of thicknesses from
100mm to 135 mm according to the minimum stipulated requirements SANS 10400-XA
Why is it important that ceiling insulation is non-combustible?
In case of a fire you want to be sure that your insulation is not combustible so that it does not propagate fire or provide a source of fuel for the flames. Non-combustible insulation does not burn and will not add to a fire in any way, it will also not produce any toxic fumes or smoke which could be a significant danger when evacuating your home. Aerolite is non-combustible and does not burn.
What are the health implications of working with Aerolite?
Aerolite poses no health hazard, glasswool products are bio-soluble meaning they will dissolve in body fluid should they be ingested in any way. Glasswool is among the most widely tested and researched building materials in use today and has received an IARC Class 111 rating, by the World Health Organisation. This means glasswool is safer than many products in use today
including coffee, pickled vegetables, diesel and petrol among others.
Glasswool may however cause a mechanical itch (similar to that caused by grass). It is advisable to wear gloves when installing Aerolite. In the case of itching, wash the affected are with warm soapy water.
In summary, what do I need to know about ceiling insulation?
1. Know the R-value of the product that you are installing.
2. Ensure that the R value complies with the requirements of SANS 10400-XA.
3. Know the fire properties of the material.
Aerolite is a non-combustible thermal and acoustic ceiling insulation that will save energy and reduce your electricity bills keeping you warm in winter and cool in summer.
