Foil Scrim Kraft(FSK) Facing

Foil Scrim Kraft or FSK paper insulation is a flame retardant, vapor-barrier, radiant barrier and is one of the most commonly used facings in the insulation industry today. A FSK insulation facing is made of lightweight aluminum foil that is layered against a fiberglass scrim and then paired with a final layer of natural brown kraft paper. This is then all laminated together using a flame-retardant adhesive.

Frequently Asked Questions

FSK insulation facing is a vapor barrier facing manufactured using lightweight pure aluminum foil fiberglass reinforcing scrim and natural kraft paper laminated together with a flame-retardant adhesive. 

FSK insulation is used as the jacket of many types of thermal insulation.Such as foil covered fiberglass duct board,FSK foil faced fiberglass blanket insulation,foil backed mineral wool insulation roll.

Yes,We can use the higher weight kraft or thicker aluminum foil.

Yes,pure aluminum foil and fireproof kraft are laminated with a flame-retardant adhesive.It’s totally fireproof.

Yes,Perforations are available

The insulation facings reduce heat gain (in the summer) and heat loss (in the winter), so it will benefit both winter and summer savings and comfort. In the summer, heat is reflected back to the outside and in the winter, heat is reflected inwards.

Kraft gsm,thickness of aluminum foil,scrim or not,perforated or not,single side or double side.

The kraft side should bond to the glass wool and aluminum foil surface should usually face indoors.

Mastering Insulation: Unraveling the Wonders of Aluminium Foil ...

Introduction:

In the realm of insulation solutions, the Aluminium Foil Scrim Kraft Laminate, commonly known as FSK Facing, takes center stage. This remarkable material, along with other insulation laminates, plays a pivotal role in various industries, from HVAC and ducting to Roofing/Building and Industrial applications. In this article, we will explore the fascinating world of FSK Facing and its counterparts, shedding light on their major applications and the industries they serve. Join us on this journey as we unveil the secrets of these versatile insulation-facing laminates.

  • HVAC & Ducting Insulation Facing Laminates:

Among the most widely used insulation laminates are the FSPE and FSK varieties. FSPE (Alu Foil – Fiberglass scrim – Polyethylene) and FSK (Alu Foil- Fiberglass scrim- Kraft) boast impressive thermal properties, making them ideal choices for HVAC systems and ducting insulation. These 3-layer/ply laminates provide excellent insulation, ensuring regulated temperatures and energy efficiency.

  • PET-Alu Foil-Polyethylene and Alu Foil-Fiberglass Scrim-CPP:

Another set of remarkable insulation laminates is PET-Alu Foil-Polyethylene and Alu Foil-Fiberglass Scrim-CPP. These laminates cater to specific applications like XLC Foam Facing, NBR, PUR, and more. Their combination of materials results in effective heat insulation, making them indispensable in numerous industries.

  • Roofing/Building Insulation Facing Laminates:

When it comes to roofing and building insulation, two-layer/ply laminates steal the show. F-PE (Alu Foil – Polyethylene), MET-PET-PE (Metalized-Polyester-Polyethylene), and METBOPP-PE (Metallized-Biaxially Oriented Polypropylene) are the go-to choices for insulation, flashing, and joint applications. These laminates prove their worth in maintaining comfortable indoor temperatures and offering protection against external elements.

  • Industrial Facing & Pipe Facing Insulation:

Industrial settings, energy plants, warehouses, and more benefit greatly from the efficiency of GC+PE (Glass cloth-polyethylene), F-PE-GC-PE (Alu foil-polyethylene-glass cloth-polyethylene), and F-PP Fabric-PE (Alu foil-Woven/Non-woven/HDPE fabric-Polyethylene) laminates. These insulation solutions are tailored to meet the rigorous demands of industrial environments, ensuring optimal performance and energy conservation.

  • Industry Served:

The versatility of insulation-facing laminates allows them to serve a wide range of industries, including industrial, commercial, residential, and essential services sectors. From data centers and offices to hospitals and residential buildings, these laminates offer reliable thermal protection and energy efficiency.

Applications:

The applications of facing laminates are as diverse as the industries they serve. These laminates find use on XLPE, XPS, NBR, PIR, air bubble film, phenolic foam, and more. Whether for roofing, duct sealing, vapor barrier, radiation barrier, or cold chain thermal insulation, these laminates rise to the occasion, ensuring superior performance and comfort.

Conclusion:

In the dynamic world of insulation, Aluminium Foil Scrim Kraft Laminate (FSK Facing) stands out as an exceptional choice. Alongside other insulation-facing laminates, it has revolutionized various industries by providing effective thermal insulation and energy conservation solutions. From HVAC systems to industrial settings, these laminates play a vital role in ensuring comfortable environments and maximizing energy efficiency. As technology and innovation continue to advance, we can only expect further breakthroughs in the realm of insulation and facing laminates, making our world a more sustainable and comfortable place to live and work.
