Product Information

Full details

The Actis Hybris Multifoil Insulation Panel (125mm) is designed for builders and renovators seeking high-performance thermal insulation for walls, roofs, and ceilings. Its key benefit is maximizing insulation in a compact 125mm thickness through its unique honeycomb structure, which creates numerous low-emissivity cavities. A caveat to consider is that optimal performance relies on correct installation, including the use of air cavities to enhance its reflective properties.

FAQs

What is the main advantage of the honeycomb structure?

The honeycomb structure creates numerous small, enclosed air cavities. These cavities are insulated from dust and air movement, significantly enhancing the product's thermal performance by reducing heat transfer through convection and conduction.

Can I use this insulation in a solid wall construction?

Actis Hybris is primarily designed for framed constructions (timber or masonry). For solid walls, it's typically used as part of a system, often with an associated air gap and framing, to create a thermal break and allow for insulation build-up. Consult specific system guidelines for solid wall applications.

How does the reflective foil contribute to insulation?

The aluminum-coated polyethylene foils are highly reflective. When an air cavity is present next to the foil, it reflects radiant heat, reducing heat transfer. This property is most effective when combined with an air gap of at least 25mm.

What are the dimensions of this specific panel?

This particular panel is 1145mm in width, 1200mm in length, and 125mm in thickness.

Do I need a separate vapor barrier with this insulation?

A vapor control layer is often recommended on the warm side of the insulation to prevent moisture vapor from reaching cold surfaces within the construction and condensing. The specific requirement depends on the overall wall, roof, or ceiling construction and the climate. Always consult building regulations and manufacturer guidance.

Is this product suitable for external use?

Actis Hybris is designed for internal applications within the building envelope (walls, roofs, ceilings). It is not intended for direct external exposure.

How many square meters does one panel cover?

One panel measures 1.145m x 1.200m, covering approximately 1.374 square meters.

Troubleshooting

Reduced thermal performance after installation

Ensure there are adequate air cavities adjacent to the insulation as recommended by the manufacturer. Check for any compression or damage to the panels. Verify that a vapor control layer has been correctly installed if required by the build-up.

Difficulty cutting panels to size

Use a sharp, long-bladed utility knife or specialized insulation saw. Score the surface and cut through the material cleanly. Ensure a stable surface for cutting.

Condensation appearing on the surface

This indicates a potential issue with moisture ingress or inadequate ventilation. Ensure a continuous and properly sealed vapor control layer is installed on the warm side of the insulation. Check for any breaches in the building fabric.

Panels sagging or not staying in place

Ensure the panels are cut to fit snugly and are adequately supported. Use appropriate mechanical fixings or battens to secure the insulation firmly within the framework. Do not rely solely on friction fit for long-term stability.

Pros and Cons

Pros

  • Provides excellent thermal resistance due to its reflective surfaces and multiple insulated cavities.
  • Compact 125mm thickness is ideal for space-constrained applications.
  • Versatile for use in walls, roofs, and ceilings in both new builds and renovations.
  • Resistant to dust and air movement within its structure, ensuring consistent performance.
  • Can enhance thermal performance further when used with adjacent air cavities.

Cons

  • Requires careful installation to achieve optimal thermal performance, particularly regarding air cavities.
  • Multiple layers are needed for very high insulation standards, potentially increasing complexity.
  • Not a rigid board; requires support during installation.
  • Performance can be affected by moisture if not installed correctly with a vapor control layer.
  • Reflective properties are less effective if direct contact is made with surrounding materials without an air gap.

Setup, Compatibility & Care

Installation:

Actis Hybris panels are designed to be cut to size using a sharp blade and fitted snugly between studs, rafters, or joists. For optimal performance, it is recommended to create an air cavity on at least one side of the insulation, typically the warm side (interior). This can be achieved using battens or by maintaining a gap between the insulation and the structural elements. Ensure the product is installed without significant compression, which can reduce its effectiveness. Use appropriate fixings to secure the insulation in place. Always refer to the manufacturer's installation guidelines for specific details related to your project type.

Compatibility:

This product is suitable for use in:

  • Timber frame walls
  • Masonry walls (as part of a system)
  • Pitched roofs
  • Ceilings

It is compatible with standard building materials and practices. For any application near sources of high heat or moisture, consult the manufacturer's recommendations. A vapor control layer may be required on the warm side of the insulation depending on the construction and location, to prevent interstitial condensation.

Care:

Once installed, Actis Hybris requires no specific maintenance. However, it is important to protect it from physical damage during and after the construction process. Avoid prolonged exposure to moisture. If the surface becomes dusty, a light brushing or vacuuming can be performed, but this is generally unnecessary for maintaining thermal performance.
