Finnfoam is a diverse and reliable thermal insulation, which maintains its insulation characteristics even in demanding conditions. Finnfoam Baton Rouge Louisiana. Its special characteristic is a fully homogenous and closed-cell structure, which guaranteed excellent and solid insulation characteristics. Finnfoam brings also a new type of ease, speed and quality to the building. The structure does not need a separate vapor barrier or wind protection sheeting. Therefore, several work phases can be completed with one installation. Finnfoam Baton Rouge Louisiana.
Strength properties
Short- and long-term compression strength ratings must be reported for all thermal insulation materials used in inverted roof structures and ground frost insulation and slab-on-ground base insulation applications as the materials used in these applications are subjected to considerable loads and stress during their lifetime.
Performing a long-term compression test (creep test) for the operational life of 50 years takes 608 days. For this reason, a quicker short-term compression strength test is commonly used in the industry. Finnfoam Baton Rouge Louisiana. Short-term compression strength is determined by compressing the material by 10% in relation to its original thickness over a duration of a few seconds, or by applying continuous compression until a fracture occurs. The test may also be used to determine a property that is much more important: the long-term compression strength (creep) of the material. Finnfoam Baton Rouge Louisiana.
Structures must always be designed and dimensioned in accordance with the long-term compression strength (creep) of the material, which indicates how much the material compacts at specific loads. Finnfoam Baton Rouge Louisiana.The long-term compression strength of Finnfoam F-300, for example, is reported as CC(2/1.5/50)130, which means 130 kPa, or approximately 13 tonnes per m². It also indicates that, at maximum load, the Finnfoam F300 compacts by no more than 1.5% over a duration of 50 years. Finnfoam Baton Rouge Louisiana.
Short-term compression strengths are only reported for reference and must not be used as dimensioning values. Instead, long-term compression strength must be used, as this value indicates the maximum long-term load the material can bear.
Finnfoam is a highly versatile, multi-purpose thermal insulation material. Standard Finnfoam insulation boards are suitable for numerous applications and purposes from ground frost insulation to foundations, sub-floors, roofs, walls, additional thermal insulation purposes and many other applications.
Finnfoam is a reliable and versatile thermal insulation system that retains its properties even in very demanding conditions. Finnfoam Baton Rouge Louisiana.

The U-value, calculated from the thermal conduction properties of the materials, rarely tells the whole story of a structure’s insulation capacity. Finnfoam Baton Rouge Louisiana.The structural air leak value (n50) also affects the structure’s insulation capability considerably. The tighter the structure, the better it’s thermal insulation capacity. Finnfoam’s cell structure is completely homogenous and sealed. Finnfoam Baton Rouge Louisiana. The U-value does not address internal convection occurring within the structure, which increases as temperature difference grows. Finnfoam is not subject to internal convection, however. Finnfoam Baton Rouge Louisiana.
Finnfoam’s thermal insulation capacity is almost completely independent of the conditions of use. The completely homogenous and closed cell structure retains the clean air used as a cell gas very efficiently. Its thermal conductivity (λ10) is 0.026 W/(m K).
Airflow does not weaken the material’s insulation capacity. This is why it can also be used as wind protection. Finnfoam Baton Rouge Louisiana.Finnfoam’s heat conductivity (λ10) is 0.029–0.034 (W/(m K), depending on the board type. Finnfoam Baton Rouge Louisiana.As the material is impermeable to water, it also retains its insulation characteristics in humid conditions. Finnfoam Baton Rouge Louisiana. This is a very important property for ground frost insulation materials.
Structures insulated with Finnfoam require no separate wind protection. For reasons of moisture management and elimination, however, Finnfoam cannot be used as a wind protection sheet in, for example, insulation wool walls. Finnfoam Baton Rouge Louisiana.
As Finnfoam’s cell gas is air, its insulation capability does not deteriorate over time. As the heat conductivity of air decreases as the temperature falls, Finnfoam’s insulation capacity increases in cold conditions and the best insulation capacity are reached at very low temperatures. The temperature value used as the dimensioning specification for ground frost insulation is -5°C. At this temperature, Finnfoam’s insulation capability is already increased. As water does not permeate Finnfoam, the material’s thermal conductivity value used for dimensioning purposes, according to the present CE and European standard specifications, is even better when exposed to humidity (0.034 or 0.036, compared with 0.035 or 0.037 for dry applications). In dry applications, the thermal conductivity value used for dimensioning is usually equal to the declared lambda value. As Finnfoam is also airproof, air flows do not have a negative impact on the material and, as the cell gas is air, no deterioration of thermal conductivity occurs over time.

Know When to Clean
Finnfoam Baton Rouge Louisiana
It is important, therefore, to use chemical cleaning only when necessary. In fact, improvements in boiler and feed water practices have reduced the need for chemical cleaning at many utilities, extending the period between cleanings by years. How can you determine when chemical cleaning is required? Consider the criteria commonly used by utilities and other operators of steam generators:
Deposit Loading On Tube Samples
Two or three tube samples should be taken from high heat flux areas of the boiler and analyzed for deposit loading on the inside of the water wall tube. Finnfoam Baton Rouge Louisiana. This is still the best way to determine the need to clean with chemicals, assuming there have been no major contamination incidents since the last chemical cleaning. Finnfoam Baton Rouge Louisiana.
Time-Based Cleanings
Cleaning based on time — either operating hours or a number of years since the last chemical cleaning — is probably the worst way to determine need. Deposits do not form on boiler tube walls at a uniform rate over time. Finnfoam Baton Rouge Louisiana. Other factors, including frequency of start-up and shutdown and water chemistry, must be considered. Finnfoam Baton Rouge Louisiana.
A Major Contamination Incident
Often overlooked, a chemical cleaning should be performed at the next opportunity when there is a major contamination of boiler water. Finnfoam Baton Rouge Louisiana. It is best to do so before the unit is restarted. A common cause of boiler contamination is a condenser tube leak. Finnfoam Baton Rouge Louisiana.
Summing It Up
The need to chemically clean the boiler should be determined by the deposit loading of tube samples, not the amount of time since the last cleaning. Finnfoam Baton Rouge Louisiana. Improving boiler and feed water chemistry and lay-up and start-up practices can extend the time between cleanings. Together, these techniques and practices also can save money and help reduce the risk of forced shutdowns. Finnfoam Baton Rouge Louisiana.
