Flat Roof Insulation

Many homes have Flat Roof sections where there is no access via the trap door. These Flat Roof sections are often braai rooms or additions to an existing roof. Some homes are built with ceiling and roof pitch very flat. This usually means the house has no Roof Insulation. This will make the home very hot in summer and very cold in winter. Having Flat Roof Insulation Installed in these homes makes a huge difference in the heat flow into the house.

When installing Insulation for Flat Roofs or homes without trap doors, we will remove Roof Tiles or Sheeting depending on the application.

Flat Roof Insulation Installers

Our Flat Roof Insulation Installers are all well trained and have extensive Roofing experience. When lifting roof sections to install Roof Insulation products, it is important to use qualified installers.

Lifting roof sheets is the easy part. However, the sealing of the roof is critical after this has taken place. Therefore, in all applications where we lift roof sheeting, we replace all roof nails and washers with new pins and washers.

We then seal the roof after the application.

Flat Roof Insulation for Braai Rooms

All Braai rooms are sweltering because the ceiling and roof are a mere 150mm to 250mm apart. This means that the heat pulled through from the tiles is compressed into a small roof cavity rather than the traditional large roof space. Thus, to build the perfect Braai room and insulate at the same time.

In fact, the ceiling in these rooms can only be described as underfloor heating in summer when you most certainly do not want this. We have, in fact, measured ceiling temperatures of up to 60 degrees C. This is radiant heat. However, it is above your head in summer when you most certainly don’t want or need this heat.

Once this space has been insulated with SANS compliant Roof Insulation the temperature difference is very significant. When the same reading is calculated for the ceiling temperature, there will be a drop of up to 25 degrees C in the ceiling temperature.

This, in turn, will equate to a very nice 4 to 10-degree drop in temperature in these rooms, In summer and a significant improvement in winter with or without the fireplace being activated.

In the Western Cape, many homes have indoor braai rooms. In fact, this is more prevalent in this region than anywhere in the country.

The assumption is that the wind factor in the Cape regions makes a braai room a great option. For example, out of the wind in summer and out of the rain in winter.

In most homes with braai rooms, they become the most occupied room in the home. This is because these rooms are like the family room in most households.

Flat Roof Insulation For Homes

Many homes countrywide have roof and ceilings that are a mere 150mm to 225mm deep. This makes insulating the homes rather difficult as there is no access via the trap door into the roof space.

In these applications, all of the roof or part of the roof will need to be lifted. With sheeting roofs, we will often only have to lift every alternative sheet to feed the insulation into the roof space.

As mentioned below, the only Flat Roof Insulation that we install is the Aerolite 135mm or the Isotherm 145mm. These Insulation products have great R-value and fire rating for these applications.
