Air Handling Unit / Silencer System Insulation

In addition to having excellent thermal and sound properties, our stone wool insulation for air handling units has a key advantage over other insulation types: It can be indefinitely recycled.

Through the Power of &, ROCKWOOL Core Solutions cover practically all air handling unit (AHU) applications, such as air conditioning insulation, make-up air units, rooftop units, terminal units etc. Whatever application you need, we can tailor it exactly to your needs and propose specialised facings for our stone wool insulation. 

Stone wool is typically classified as a non-combustible material 1 & 2, which means it has minimal or zero contribution to the spread of fire. Stone wool insulation will not ignite when exposed to flames and can prevent fire from spreading to other materials. By limiting fire spread, stone wool also contributes in assuring the safe escape of buildings’ occupants and first responders’ intervention.

No, stone wool does not contain flame retardants. Although there are many types of flame retardants, research has shown that some of the chemicals can have a negative impact on health and environment. Stone wool is naturally fire resistant, which is why our products do not contain any flame retardants. 

Stone wool’s thermal performance compares well versus other insulation products. Stone wool might have a slightly higher thickness than some other materials in order to reach the same R-value. The most important aspect, however, is that its thermal performance does not decrease over time. The R-value of stone wool insulation will remain stable over the lifetime of the building.

The unique thing about stone wool is that its mechanical performance can be designed to fit different types of applications. High compressive strength can only be an advantage in certain types of constructions whilst in others it can lead to poor fit-ability.
