Having your home insulated, with ceiling insulation that meets the Building Code of South Africa guidelines, will increase indoor comfort. Moreover, high electricity bills can be reduced by up to 45% in residential and commercial buildings. These savings are massive.
BEST CEILING INSULATION PRODUCTS
There are a few products in South Africa that stand out above the rest. These are SABS tested and approved materials and they hold the best R-values available. They all comply with climatic zones requirements. Below is a list of these recommended products:
CLIMATIC ZONE REQUIREMENTS
When installing the ceiling insulation, your climatic zone plays an important role in the thickness of the material that is recommended for installation. Different ceiling insulation requirements are set for each area. For a price get hold of your local installers in Johannesburg and Pretoria for ceiling insulation prices.
RECOMMENDED CEILING INSULATION R-VALUE
Ceiling Insulation materials should be selected based on R-value and density. The higher the R-value, the better the product will perform. The climatic zones requirement is a minimum and can be exceeded if need be.
HOW DOES HEAT TRANSFER WORK?
Heat transfer happens when there are two objects next to each other. If one of the objects is warmer than the other, the cooler object will eventually start to warm up as well through the process known as heat transfer. Moreover, there are 3 types of heat transfer:
This is the flow of energy (in the form of heat) from one object to another. Furthermore, the transfer of heat will stop when both objects are at the same temperature. High-quality polyester or fibreglass materials prevent heat transfer. Stopping heat from entering as well as exiting.
BENEFITS OF CEILING INSULATION PRODUCTS
Heat loss can still occur in an insulated home. Sealing up any drafts and gaps and cracks around doors and windows can make a huge difference. Additionally, double glazed windows should be installed for maximum heat loss prevention.
There are many benefits of ceiling insulation materials installed in residential, commercial and industrial properties. Below is a list of the most common advantages:
- Comfort control. The most obvious benefits of ceiling insulation are keeping your home comfortable throughout the year. Moreover, keeps the temperature consistent.
- Improves energy efficiency. The heat generated indoors rises but does not pass through the product. Furthermore, rooms indoors tend to warm up fast and stay warm for longer. Additionally, in summer, the heat that enters your roof void doesn’t pass through the material and into the house.
- By increasing the insulation in a home, less energy will be used to heat and cool the interior. In turn, reducing the amount of power used to keep it at a comfortable temperature.
- Pay up to 45% less on heating and cooling bills. Additionally, saving you money. Moreover, it can pay itself off in 2 – 3 years and has continued savings thereafter.
- Reduction in moisture problems. By insulating your home properly, the moisture problem may be solved.
HOW TO INSTALL CEILING INSULATION MATERIALS
Depending on the age of the insulation and how it’s been installed, you might need a top-up layer. In most cases, homes are actually under-insulated.
When installing the ceiling insulation products, they must fit snugly between the joists. Additionally, no gaps must be left. 100% coverage needs to be achieved for the highest thermal and acoustic results. It’s advised to use ceiling insulation installers in Johannesburg and Pretoria for best results.
Plasterboard alone has a small R-value of 0.2. Although, not enough for temperature control. Once the new material has been installed, it will boost the R-value to the level of your chosen product
IS MY CURRENT INSULATION EFFECTIVE?
By topping up or adding more material to the existing layer, it will boost your total R-value. Additionally, increasing thermal and acoustic performance. Even the smallest gaps can cause a massive decrease in performance of up to 50%.
Depending on whether you are a handy person, you might consider doing a DIY installation. In most cases, it’s best to let the professional insulation installers handle the installation.
Consider the following:
To insulate effectively, you need to make sure you cover all the areas in the roof. Remember, leaving gaps will reduce ceiling insulation thermal performance. Areas to insulate include:
- Under Roofing Materials – Sisalation Radiant barrier
- Directly on The Ceiling – Bulk insulation products
- Outdoor patios should also be insulated properly.
Furthermore, this will prevent heat build-up that could potentially heat the house up.
CORRECTLY INSULATING YOUR WALLS
Furthermore, appropriate wall insulation will result in a much more comfortable home. Homeowners often underestimate the radiant, conducted and convected heat that penetrates the walls. Insulation must be installed in the following areas:
- within cavities spaces
- snugly within stud frames
- outside of stud frames
- inside or outside of solid walls
