What are the benefits of using cellulose fibre for roof insulation?

Cellulose fibre insulation, especially when combined with the aerated installation method, provides an outstanding snug fit. This ensures an ambient temperature year-round. Made from recycled paper and inorganic salts, it’s both non-allergenic and non-toxic, enhancing the health of your living space by preventing mold buildup.

How much should I expect to pay for roof insulation in the Cape?

The average cost for roof insulation in CT is between R60 to R90 per square meter. However, prices can vary based on the size of your roof due to minimum costs associated with insulation projects. For a precise quotation, it’s best to provide specific details or measurements.

Are there specific guidelines or regulations for insulating roofs?

Yes, according to the new national building regulations (NBR) SANS 10400 – XA, all new constructions and modifications need to be insulated to conserve energy. Although this rule mainly applies to new structures, it underscores the importance of insulation for all homes.

Can I install cellulose fibre if I have existing, older insulation?

Depending on the condition of your current insulation, we might be able to spray over it or it may require removal. It’s advisable to remove deteriorating fibreglass insulation because it can break down and release toxic fibers. For cellulose that wasn’t installed to the latest recommended thickness, we can easily top it up.

What would happen if there was a fire if I use cellulose fibre?

Cellulose insulation acts as a fire retardant. In case of a fire, it slows down its spread and might even help contain it. Its effectiveness as a fire retardant even improves over time, making it a safe choice for homes.

How does cellulose fibre insulation impact my energy costs?

Cellulose fibre insulation installations are around 36% more airtight, saving about 26.4% more energy compared to alternatives. The City of Cape Town also estimates that up to 60% of heating and cooling costs can be saved through insulation. Ultimately, this means you’ll spend less on heating and cooling, translating to savings on your energy bills.

What is the lifespan of cellulose fibre is there a guarantee?

Cellulose fibre insulation offers a lifetime guarantee as long as your roof and ceiling remain undisturbed and intact. Though it might need occasional maintenance, replacements are generally unnecessary. If needed, we can top up the insulation without completely redoing it.

How effective is cellulose insulation in regulating temperature?

Cellulose insulation helps maintain a comfortable, ambient temperature. In summers, it prevents excessive heat from entering through the ceiling, and during winters, it retains warmth inside. For instance, a house we worked on in Fish Hoek maintains roughly a 21°C temperature year-round due to the effective insulation combined with optimal room design.

How does cellulose fibre respond to moisture and the wind?

How does cellulose affect my air conditioners or fireplaces?

With effective insulation like cellulose fibre, the need for heating or cooling appliances decreases significantly. The desired temperature is achieved more quickly and retained longer, so you’ll find yourself using such appliances less frequently and for shorter durations.
