Frequently Asked Questions

Does the grade of the pyrogenic silica affect the thermal performance?2023-02-09T14:33:28+00:00

Yes, the m2 per gramme influences the thermal performance, Siltherm produce their own pyrogenic silica and are able to produce grades of ultimate performance

Is microporous insulation more expensive than alternative light weight insulations?2023-01-13T04:29:34+00:00

Not necessarily, the introduction of microporous insulation can deliver the same value for the same cost of ownership.

How does microporous insulation compare to other light weight insulations at elevated temperatures above 600 deg C, does the thermal conductivity escalate in a similar way?2023-01-13T04:29:22+00:00

No, microporous insulation contains a form of “opacifier”, often a metal oxide, this acts as a reflector for radiant heat flow which results in a much lower thermal conductivity at temperatures above 600 deg C.

Are there any physical benefits, apart from reduced heat flow?2023-01-13T04:29:09+00:00

Yes, the introduction of microporous insulation can also allow you to reduce the weight of your system, or save space by making it thinner.

Can the advantage of lower thermal conductivity deliver benefits to my current insulation system?2023-01-13T04:28:53+00:00

Yes, the introduction of microporous insulation can allow you to reduce the heat flow through your system and lower the cold face significantly depending on the ambient temperature

Is it true that microporous insulation is up to four times more insulating than alternative light weight insulations such as calcium silicates and fibrous insulations2023-01-13T04:28:40+00:00

Yes, microporous insulation typically has a thermal conductivity of between 0.02 and 0.034 W/m-K , whereas light weight calcium silicates and fibrous insulations are between 0.07 and 0.20 W/m-K
