    The new “Rockassist” calculation program now online

    27th April 2015

    Many insulation installers and engineers used and appreciated the previous version of Rockassist, the thermotechnical calculation program from ROCKWOOL Technical Insulation, for determining the dimensioning and configuration of technical insulation. The immediately available new online version of the program (available for laptop, tablet and smartphone) offers many additional functions and the right calculation method for any need. “That’s why we’re quite sure that there will now be another big jump in the number of Rockassist users,” says David Riddell, National Sales Manager of ROCKWOOL Technical Insulation.


    The new, intuitive “QuickCheck” mode provides a quick overview of the technical insulation material needed. This makes it ideal for use in consultation meetings at the counter or construction site. Once a few parameters have been entered, such as the shape of the object, the operating temperature of the medium and permissible surface temperature, the “QuickCheck” provides a recommendation on type of insulation and insulation thickness within seconds. The program factors data into the calculation such as ambient temperature, wind speed and the type of cladding with a common applicable value in practice.


    Precisely tailored to any project

    If the “DetailedCalculation” method is preferred, then the specific parameters of a structure are entered manually. The technical insulation will then be configured precisely for the application situation in question. “This takes of course more time to prepare and enter, but it has the advantage that it calculates optimised insulation based on your individual specifications and insulation thickness and minimises heat loss,” explains David Riddell. The “DetailedCalculation” and five other calculation options which the new version of Rockassist offers are aimed at experienced engineers and insulation installers who have already dealt with the program. “We offer training sessions on request for the new version of Rockassist free of charge for anyone who’s uncertain. This is a great opportunity for beginners to learn how to make the best use of the program. Those who attend the training sessions will learn the ropes of all Rockassist functions, and we also provide information on the latest findings on engineering complex insulation projects.”


    Online calculation

    Rockassist is purely web-based, so it does not require any memory space on your own computer, is available everywhere online and can be used free of charge. It can be accessed with the latest version of Mozilla Firefox, Safari or Internet Explorer 8.0 and used on your laptop, tablet and smartphone. The results determined with the program provide a comprehensive overview of insulation thickness, surface temperature, heat losses, savings and CO2 emission reduction. All of the results are provided in PDF form and can be forwarded directly to the customer. In addition to that, Rockassist’s calculation results are displayed in both numerical tabular form as well as graphically in a curve.


    For an impressive presentation

    The curve clearly illustrates the correlation between insulation thickness, surface temperature and heat loss and can convince customers of the better solution. “For example: In many cases, very low insulation thicknesses of just 80 mm will suffice to meet the surface temperature requirement of < 60 °C specified in accident prevention regulations. But the curve also shows the surface temperatures and especially the reduced heat losses at high insulation thicknesses. This means that a potential customer can tell at a glance that 120 mm thick insulation can sharply reduce heat losses in comparison with an 80 mm solution at only a slightly higher cost. This is important information when it comes to calculating cost effectiveness,” is David Riddell convinced.


    The latest version of Rockassist can now be found online at For the moment Rockassist is available in English and German language. Anyone interested can set up their own user account free of charge in just a few minutes and start making their own calculations right away.
