 Boiler penthouse insulation

Flexible insulation solutions avoiding heat loss and thermal bridges

As boiler penthouses have pipe connections above the boilers, special insulating structures are required that can bear the weight of maintenance staff and plant operators. PAROC® offers insulation solutions for boiler penthouses that can help minimize thermal loss and thermal bridges and prevent the boiler room from overheating. Our stone wool insulation material has a high flexibility and mechanical strength, which supports optimum insulation even with large temperature fluctuations.

This is necessary because the insulation material for the boiler penthouse has to withstand the extremely high temperatures of the boiler, while the temperatures in other areas can fluctuate. In addition, the casing and pipes of boilers are often exposed to constant vibrations caused by connected devices such as burners and fans.

This allows you to control your boiler's process temperature, enabling it to work more efficiently and increasing its overall operation performance. Lower energy consumption also means lower CO2 emissions.

Please consult the respective product data sheet for more information.

Benefits from process boiler penthouse insulation

For high temperatures

Our products can provide long-lasting performance also at high temperatures and are resistant even at service temperatures of up to 700 °C, ensuring smooth operation.

Please consult the respective product data sheet for more information.

High flexibility and strength

Our PAROC® Pro Slabs (WR), Wired Mats (WR) and Mats (WR) have been specially developed to meet these challenging demands and offer optimum insulation properties even in the event of major temperature fluctuations due to stone wool’s high flexibility and mechanical strength.

Please consult the respective product data sheet for more information.

Flexible insulation 

The insulation material for boiler penthouses should be flexible enough to fill all cavities and strong enough to withstand temperature fluctuations. To prevent radiant heat within the insulation, we recommend to use aluminium foil-faced products in the insulation build-up.

All PAROC® stone wool insulation products for industrial applications are well suited for use at elevated temperatures due to their high temperature resistance, high flexibility and mechanical strength. Our stone wool products' excellent thermal properties can withstand extremely high temperatures and large temperature differences in different parts of the boiler. Please consult the respective product data sheet for more information.

When planning the insulation, the boiler type and the boiler manufacturer's specifications should be considered. According to the requirements in many specifications, boilers commonly have to be insulated in multiple layers and the insulation thickness should be between 200 and 300 mm in total. Special attention should be paid to indoor applications with elevated operating temperatures. The boiler type and the boiler manufacturer's specifications should be taken into account when choosing the insulation.

Top performance thanks to the right insulation of the top layer

We recommend a boiler penthouse solution made of PAROC® Pro Wired Mats (WR) or a combination of PAROC® Pro Wired mats (WR) and PAROC® Pro Slabs (only the upper layers).

A commonly used solutions is several layers of aluminum-laminated PAROC® Pro Wired Mat (WR) 680 AL1. The number of layers and the thicknesses per layer need to be determined on a case-by-case basis. Another great alternative for the top layer is to apply a layer of PAROC® Pro Slab (WR) 640 or 660 to the layers of PAROC Pro Wired Mat (WR) 680 AL1 below.

Based on our certifications to ISO 14025, ISO 21930 and EN 15804, we have received the Environmental Product Declaration (EPD) numbers NEPD-4100-3121-EN and NEPD-4101-3121-EN.
