Phenolic foam does not tend to have the same kind of temperature range as mineral wool, but that does not prevent it being used in the majority of heating and cooling applications. It is also becoming more commonly specified in the domestic sector, with ever increasing efficiency required for building regulations and a desire from home owners and self builders to think of the long term environmental impact of their home.
Of course, as well as its use as a pipe insulation Kingspan Kooltherm is also a leading name in building insulation boards. Phenolic is often regarded as the best material to use, usually a little more expensive but taking a longer term view it is more efficient that PIR. The building boards can be used in cavity walls, under floors and in ceilings and loft spaces. A lot will depend on budget but, as with the pipe insulation, using a more efficient product can also mean you use less space.
One key thing to consider when using a phenolic foam such as Kingspan Kooltherm is that it is more brittle than other types of insulation, so will not be as forgiving of damage as flexible foams or mineral wool. particularly with pipe insulation it will often be necessary to provide additional cladding to protect the material in areas that see a lot of foot fall. There are also a few "pre clad" phenolic foam systems around that provide external weather protection and some resistance to damage.
