High Performance Thermal Insulation Specialists In The Cape

WHY CONSIDER USING CELLULOSE FIBRE?

The combination of recycled paper and the aerated installation method creates an excellent snug fitting insulating layer, resulting in a more ambient temperature throughout the year as well as saving electricity, gas or wood consumption. Real live tests on identical buildings found that cellulose fibre was 36% more airtight and saved 26.4% more energy than fibreglass or blanket type insulation, as well as kept the building 4 degrees warmer during colder months.

TECHNICAL INFO

The new national building regulations (NBR) SANS 10400 – XA, require all new buildings and alterations to be insulated in order to save energy. (View Document Here)

With the extreme weather we are experiencing and rising energy costs, it makes sense to retrofit insulation on existing buildings. You will live in a better environment and the cost savings mean that the insulation will pay for itself.

Cellulose fibre has been approved by the SABS and fire tested SANS 428 and classified B/B1/2.

Eskom have completed studies on the different climate zones and a R-Value of 3.7 is recommended Down lights, fans and any heat source is protected by a galvanised sleeve.

*The R-value is a measure of the thermal resistance of a material. The R-value given is the total measurement of the roof assemble and insulation combined.

FREQUENTLY ASKED QUESTIONS

Click on the + below for all our answers

What does it cost?

Cellulose is the most economical insulation available.  The cost is dependent on the thickness of the cellulose, square meterage and the number of down light sleeves required.

How much energy will I save?

The City of Cape Town estimates up to 60% of your heating and cooling cost can be saved through insulation. (link to page) Ensure that you insulate your ceiling prior to installing air conditioning or heating as you might find that installation of air conditioners / heating is no longer required due to the efficacy of the cellulose fibre insulation.

How thick should it be?

The new building regulations recommend as a minimum “deemed to satisfy” thickness of between 100 to 135mm thick. This will give you an R-value of 3.7. (link to page)

How much does the temperature change?

The temperature will be a more ambient temperature. During summer months, the heat is prevented from penetrating the ceiling, keeping your home cool.  During winter months, the warmth is kept inside. A house where we installed insulation in Fish Hoek maintains a temperature of around 21 degrees through summer and winter due to the living room/kitchen design and ceiling insulation. The other rooms fluctuate more due to bigger windows.

How long does the installation take?

An average size house (110 square metres) takes approximately four hours. The whole installation process is quiet, quick and clean. The installation process is also owner supervised.

What if I have an air conditioner or fire place?

You will need to use them a lot less often and for  shorter periods. The required temperature is reached quicker and lasts longer once switched off. The effect is also spread further into the home.

Does it need maintenance?

No maintenance required.

I have old insulation that is not working?

Depending on the state of the insulation we can either remove it or spray over it. It is best to remove old fibreglass insulation as it breaks down and the fibres become toxic. We can top up Cellulose that was not installed to the new recommended thickness.

What if it gets wet?

Cellulose can handle small amounts of water as it will naturally dry out. Major leaks may need the insulation to be dried outside and then replaced. Generally all insulation materials trap water and need to be dried out.

I have a lot of wind in my roof?

Wind in the roof is a good thing as your roof needs to breath. Cellulose mats together and can handle a lot of wind. We can put netting if the wind is extreme.

What if there is a fire?

Test proved it is better to have Cellulose insulation as a fire retardant if you did have a fire. It will slow the fire down and may even help contain it. It also gets better with time.

What about allergies and is it safe?

Cellulose is non-allergenic and the fire retardant is also used in medicine.

Does it have a guarantee?

Cellulose comes with a lifetime guarantee as long as the insulation is not disturbed.

CUSTOMER FEEDBACK
Gordon Summerfield, Somerset West
Thought that I would give it a few weeks before getting back to you – thanks for a great job – we have noticed a good drop in in-house temperature, so I can confirm your product works. Thanks once again (it is no easy job in summer!) very glad we decided to do it and for your service.
Karla Peet, Gardens
I just wanted to say, I really “Love my insulation”… it has made my flat so perfectly temperate and so much more pleasant to be in. I don’t dread coming home anymore.
Brent Siebritz
We can definitely feel the difference this winter. Its definitely warmer inside compared to last year this time. Normally by now every evening we would sit in the lounge with a blanket but so far this year we haven''t needed to 🙂 . We haven't even had the heater on as of yet to be honest.  ~June 2020~
Grant Momple, Paarl
A quick note from a very satisfied customer out in Paarl. Your insulation works very well. Sometimes I cannot believe that I have not put on the aircon when I compare the cool temperature inside the house compared to outside. A product that I will certainly recommend to friends and colleagues!
Nevil Carrington, Fish Hoek
Our house now feels as it has a blanket over it – We are extremely happy!
Ricky Asher
Thank you very much for your outstanding service and work ethic. We have really enjoyed utilizing your services and will most certainly recommend your company to our friends and family. I have already informed our neighbour of this and the positive results from the installation. To give you some idea of the results: Our son's bedroom has averaged on 20-21 degrees since the installation (Up from +-17 degrees prior to that). Our house is much cosier and feels like a true home now (we don't freeze at night or early mornings) - the chill factor has gone! The noise level seems to be reduced, especially the sound of our alarm which rings out when armed / disarmed (I'd say a 50-60% decrease in this) - to the point that I need to be very quiet to hear that it turns on (which isn't a problem)  ~May 2019~
