Pre Compressed Expanding Polyurethane Foam

Pre Compressed Expanding Polyurethane Foam

Pre-compressed Expanding Polyurethane Foam works by stretching/expanded slowly inside the joint to its final thickness, forming a rain resistant joint, therefore highly efficient for weather sealing and usually found in roof joints, window/door seals. Advanced Seals & Gaskets Ltd are able to manufacture a wide variety of products from Pre-compressed Expanding Polyurethane Foam including:

  • Sheet
  • Rolls
  • Strip
  • Coils
  • Gaskets
  • Pads
  • Seals

All of the above can be manufactured in either plain or self-adhesive backed, peel-able liner on one or both sides. Pre-compressed Expanding Polyurethane Foam has many excellent properties including sound and vibration insulation and weather resistance making it a popular products for use in rooflights/solar panels, roof joints, conservatory seals, window/door seals and ductwork.

    What are Pre-compressed Expanding Polyurethane Foam?

    Pre-compressed expanding polyurethane foam, often referred to as pre-compressed foam sealant tapes, is a specialized sealing and insulating material used in construction, particularly for sealing gaps and joints in building envelopes. It consists of a foam tape that is pre-compressed or pre-squished during manufacturing and then expands when installed, creating a seal that provides several benefits. Here are the key characteristics and applications of pre-compressed expanding polyurethane foam:

    Key Characteristics:

    Pre-compressed Form: The foam tape is manufactured in a pre-compressed or pre-squished state. This means it is compressed to a smaller size than its final, fully expanded state. This compression allows it to be easily inserted into gaps or joints.

    Expanding Properties: When the pre-compressed foam tape is released or exposed to the air, it gradually expands to its original size, filling the gap or joint. This expansion exerts pressure on the surrounding surfaces, creating a tight seal.

    Polyurethane Composition: Pre-compressed expanding foam tapes are typically made from polyurethane foam. Polyurethane is known for its excellent insulating and sealing properties.

    Advantages of Using Pre-compressed Expanding Polyurethane Foam

    Effective Seal: Pre-compressed expanding foam tapes create a tight, effective seal, preventing air and moisture infiltration. They improve energy efficiency and contribute to a comfortable indoor environment.

    Ease of Installation: These tapes are easy to install due to their pre-compressed form and adhesive backing. They can be quickly placed in gaps and joints, and their expansion fills irregularities.

    Thermal Insulation: Polyurethane foam offers thermal insulation properties, helping to maintain consistent temperatures and reduce energy consumption.

    Waterproofing: Pre-compressed foam tapes are often water-resistant, preventing water ingress and protecting against moisture damage.

    Sound Dampening: In addition to sealing and insulating, they can contribute to soundproofing by reducing noise transmission.

    Why use Pre-compressed Expanding Polyurethane Foam?

    Pre-compressed expanding polyurethane foam tapes find application in various construction and sealing scenarios, including:

    Window and Door Sealing: They are used to seal gaps and joints around windows and doors. The expanding foam tape fills any irregularities, preventing drafts and improving energy efficiency.

    Curtain Wall Installation: In curtain wall systems, these tapes help seal the joints between panels and the building structure, providing both weather resistance and insulation.

    Expansion Joint Sealing: Pre-compressed foam tapes are used in expansion joints to accommodate movement while maintaining an effective seal. This is important in structures like bridges and parking garages.

    Roof and Wall Panel Sealing: They are applied between roof and wall panels to create a watertight seal and improve the thermal performance of the building envelope.
