Armacell elastomeric insulation

Armacell is the leading closed cell elastomeric thermal-, and acoustic insulation product manufacturer in the world.The company delivers highly innovative, high quality products and systems around the globe. Kespet Oy supplies all Armacell products in their catalogue – below you’ll find a few examples of popular products.


Armaflex XG

Armaflex XG is a flexible solution for condension insulation in HVAC and cold installations. The combination of it’s technical properties – low heat conductivity and high steam diffusion resistance – and a competitive price make it a cost effective solution that saves energy.

The Armaflex XG line covers most pipes used in installations of this type, including thermoplastic pipes. The product minimizes heat loss, and possesses reliable condension insulation properties. Armaflex XG is produced from a closed cell, highly flexible elastomeric material, with synthetic rubber as the base raw material. A thin polyethylene film covers the surface.

Armaflex Ultima

The first elastomeric insulation product that has the Euro-class BL-s1, d0 (tubes) ja B-s2, d0 (slabs) approval. Armaflex Ultima fulfills modern requirements and reduces the risk of personnel injury. Flexible, reliable and safe. Ultimate is manufactured utilizing the patented Armaprene -technology. The flexible closed cell material produces extremely low amounts of smoke, therefore having a positive effect on the general fire safety level of any building.

Armaflex Ultimate also meets the Green Building certificatoin requirements. It can be used in HVAC construction, cooling systems and processing machinery and facilities. Low heat conductivity and high steam diffusion resistance (µ ≥ 7.000). The Ultima product family includes a perfect selection of pipes, mats, slabs, self adhesive tapes and Armafix -pipe holders.

Paroc stone wool products

Paroc stands for energy-efficient and fire safe insulation products and solutions of stone wool for new and renovated buildings, HVAC, marine and offshore, acoustics and other industrial applications. Behind those products there is an 80-year history of stonewool production knowhow backed with technical insulation expertise and innovation. Kespet Oy supplies all available Paroc products – below you’ll find a few examples of popular product categories.



Paroc HVAC Section AluCoat T

Properly designed and insulated HVAC installations serve as one of the foundations of sustainable and energy-efficient building. Designed for demanding conditions, PAROC Hvac Section AluCoat T makes a reliable product, meeting a number of requirements for a properly working installation, as well as ensuring quick and easy fitting.

PAROC Hvac Section AluCoat T is a non-combustible stone wool pipe section for thermal and condensation insulation of pipework and air ducts in buildings and ships. It has a reinforced aluminium foil facing and tape in the longitudinal seam which prevents condensation and gives a quick installation.

PAROC HVAC Fire BlackCoat

The new BlackCoat product family solutions cover the fireproofing classification EI15-EI120 for both round and rectangular ducts. The wired mat and slab products are covered with a black aluminium laminate foil. Fireproofing classification EI30 for round ducts and channels got even thinner, with insulation thickness being at 50 mm. Horizontal and vertical channels and ducts utilize the same product thickness against both internal and external fire hazards.

The products also function well in thermal-, and acoustic insulation use. The slab solution is condension sealed after all seams have been properly taped over. For this purpose, the PAROC BlackCoat Tape is available, matching perfectly with the insulation product’s color so a polished final look can be achieved. Paroc HVAC Fire BlackCoat -products have the Eurofins-product certificate EUFI29-19000981-C.


ISOVER as a manufacturer offers multiple insulation solutions for different sites and usage. The catalogue includes safe products developed for all insulation needs. Construction, HVAC, industrial, marine and machinery insulation products can be found from the ISOVER selection. Kespet supplies the whole catalogue!



ULTIMATE offers excellent performances in fire, thermal and acoustical protection. Often almost twice lighter, more flexible, with a higher compression, and with a better thermal performance (reduced insulation thickness) than tradition mineral wool. ULTIMATE brings a lot of advantages to contractors, specifiers and distributors in residential, industrial (high temperature), and marine applications. ULTIMATE gives the possibility to save weight, to improve worker conditions and to design high performing constructions.

The innovative next generation material has excellent thermal-, and acoustic insulation properties, is fully firesafe, handles temperatures up to 700 degrees Celsius and is also fully environmental friendly.

ROHHE is the leading European mineral wool insulation manufacturer. We have full range of effective and durable insulation products for construction industry. ROHHE HVAC, process and equipmet industry tehcnical insulation are made of stone wool that is naturally durable and fire safe material.

All products have CE-certificates.

Flow a mineral wool lamella mat

is a lamella mineral wool mat covered with reinforced aluminium foil. The mineral wool used has fibers perpendicular to the insulated surface.

r.Flow A lamella mat is designed for thermal, anti-condensation and acoustic insulation for ventilation and air conditioning ducts. This product is also used for insulation of heating systems.

r.Flow A has lamella system of mineral wool fiber and because of that the thickness of insulation remains constant all over the surface. This is especially importat in corners and bends of isolated elements. Thanks to its construction r.Flow®A is resistant to squeezing, thus maintaining excellent flexibility and consistency.

Heat a mineral wool pipe section

r.Heat®A is a pipe section made of mineral wool coated with reinforced aluminium foil. The mineral wool has a high temperature (up to 300°C) resistance and its longitudinal fiber arrangement gives the product both rigidity and optimal thermal insulation properties. r.Heat®A:ssa has a longitudinal assembly cut and a wide, self-adhensive closing tab. r.Heat®A is intended for thermal, fire, anti-condensation and acoustic insulation of piping systems. The product is used in heating, ventilation, sanitary and industrial installations. The use of a reinforced cladding finished with a wide self-adhensive closing tab makes the assembly process both quick and secure.  Low chloride ion content (CL10) reduces the risk of corrosion of isolated components.

r.Heat®A has a unique system of maintaining the round shape of its internal diameter. Due to the special technology used to shape the walls of the pipe section, the loss of material within the assembly gap does not affect the round shape of the internal diameter. Thanks to this property the r.Heat®A  pipe section installed on the pipeline is tightly closed at the point of cut and ideally adheres to the pipeline, which directly counteracts the occurrence of “cold bridges”.
