Cellulose fibre Removal
Cellulose fibre removal has become quite difficult to remove as it gets older. As it has possibly absorbed more moisture in the winter months. As
well as rain, obviously being very fine shredded paper it will absorbs water. This sometimes makes it very difficult to vacuum that we need to take it out chunks.
- Unfortunately with cellulose fibre insulation is not that easy to detect a roof leak. As the cellulose fibre absorbs most of the water and it does not always show up in the ceiling immediately. In fact this can end up with the ceiling collapsing.
- When this has happened there are two problems one is that mould will develop on the ceiling and the insulation can become very hard as it dries.
- To remove old cellulose fibre insulation is quite difficult to remove at times. Especially when the wet cellulose fibre has dried it becomes very heavy and can fall apart as it is being removed.
- For this reason extreme caution must be used when removing old dry cellulose fibre
- We would generally vacuum the roof area first removing all the soft cellulose insulation and then pick up the hard chunks. As they cannot be vacuumed out of the roof.
- The cellulose fibre removal process would be changed to breaking the solid sections down and removing them in smaller pieces.
- Standard Roof Vacuum could not possibly do this top removal, heavy duty industrial machines are needed for this application.
Cellulose Fibre Removal in Roofs.
- Although cellulose fibre insulation is effective as insulation it has a few problems, wind moisture and rain.
- Some of the main reasons for cellulose fibre removal is the Cape Weather. So the Rain and moisture play a big part.
- Some roofs allow huge amounts of wind to blow through. And because cellulose is a loose fill DUST type insulation it can be blown around in the ceiling. And this is a common reason for cellulose fibre removal.
- Another reason for cellulose fibre removal is that as the product ages it loses some of its fire retardant properties. As they dissipate with time and this can become a fire risk.
- Damaged or cracked ceilings and were cornice peace’s have pulled away from the wall the dust falls down and cellulose fibre removal is then an option.
- Because Cellulose fibre is a fine dust like paper, in roofs that have a tendency to have leaks the leak is not easily detected as the paper absorbs the water and the insulation can become very heavy.
- Mould on the ceiling can be caused by cellulose absorbing water.
- In recent years cellulose installers have been installing tapered cones over down lights to stop the dust from blowing onto the down lights. This has become a big change is with all insulations a gap around the light are important so they can breathe. This becomes less of a fire risk.
- As we know some down lights can reach temperatures of 270 deg up to 320 deg. and should there be fine cellulose fibre dust on them this could become a fire hazard.
- Even the roll form insulations need to have a breathing hole over the down lights.
Do We Remove Other Insulation Types?
- We remove all insulation types as well as general dust and leaves.
- We remove old Aerolite and badly fitted insulation
- Old isotherm or badly fitted insulation is also removed.
- Roof Insulation also remove the old loose fill fibreglass insulation as it is also affected by wind in homes that have roofs that allow a lot of wind to blow through it has never been commonly used in South Africa.
