+What is Insulation?
Insulation creates a thermal barrier that resists the transmission of heat. In the case of your home this will probably be made up of a thick layer of bulk insulation. By creating this thermal barrier, the well insulated home will be able to minimise the effects of temperature swings externally, and maintain a more comfortable, moderate temperature without excessive use of heating and cooling systems.
+How is the insulation done?
There are two methods of insulating a roof, the first way is normally in a tiled roof, lifting the roof tiles and entering via the roof, this allows light and fresh air for the operators to insulate consistently. The second way is normally done in the event of a corrugated iron roof, the operators will make use of the trapdoor as an entry point and insulate from there.
+How long will it take?
This can vary depending on the size of the area to be insulated, the type of roof and the number of Downlighter covers installed. Your operator will be able to give you a more accurate time depending on your individual home.
+Can i Insulate Sections of my home?
Yes you can, individual rooms can be insulated, however there will still be heat gain/loss in the rooms adjacent and as such may not give you the full benefits of insulation. This is a good option for families expecting a new member and would like to make sure of their little one has a comfortable room in which to sleep.
+What about downlighters?
Downlighters create excessive heat, and with insulation on top of them can cause them to overheat and burnout. For this reason, Covers are installed wherever downlighters are situated. Covers are still required even when Installing LED downlighters. LED downlighters can not only reduce the risk of burning out, but can also help with heat and will help with energy saving.
+How do the different materials differ?
Each type of insulation has its own pros and cons, be it loose fill or Rolled insulation, its R-Value and thickness required and whether or not it is rodent repellent, price etc. Your Operator will help you choose the best insulation for your needs.
+What is the “R-Value”?
The R-value of a material is its resistance to heat flow and is an indication of its ability to insulate. It is used as a standard way of telling how good a material will insulate. The higher the R-value, the more effective the insulation.
+What is SANS 10400-XA?
- SANS 10400-XA is the National Building Regulations (NBR) states that all new buildings and building extensions are required to comply with energy saving requirements.
- Roof assemblies are required to meet a minimum total thermal resistance
(R-value) as specified for the various climatic zones. This can be achieved by installing thermal insulation.
+How much do i need to insulate?
This will change from area to area and also within those areas depending on your location. TIASA (Thermal Insulation Association of Southern Africa) has a “deemed to satisfy” list of insulation types and its required minimum thickness for each region of South Africa.
+Are there extra benefits to insulating my home?
There are a host of additional benefits to insulation than just the thermal properties. Depending on which insulation used these can range from, acoustic insulation, rodent repellent, energy efficiency, etc
