This pack of four 90mm thick Hybris Reflective Multifoil Insulation Panels from Actis provides a total 5.49m² coverage, perfectly suitable for masonry walls or timber frames, pitched roofs or ceilings. As well as outstanding thermal performance and airtightness, this cost-effective solution helps to keep your home energy efficient and offers high acoustic comfort and moisture and wind resistance.
Lightweight and easy to handle and install, this high-performance insulation features a unique honeycomb structure that will not compact over time, with flexibility that ensures thermal bridging is virtually eradicated. With several low-emissivity cavities protected from excessive air movement and dust, these panels are fabricated from shaped polyethylene foams that are fixed to aluminium-coated polyethylene foils. The low-emissivity outer films also deliver further thermal resistance when combined with air cavities.
Question:
Would Actis insulation be suitable for a flat roof extension with a balcony above? It needs to achieve a 0.13W/m2K insulation value. Can it go on top as a warm roof design or would it go below between joists? If it can be done do you have a drawing of a standard installation?
Answer:
The Actis Hybris Panel Reflective Multifoil Insulation is a flexible product suitable for insulation in ceilings, walls, and roofs. However, the specific U-value you're aiming to achieve (0.13W/m2K) would depend on a variety of factors including the overall construction of your roof and the combination of insulation materials used. As for your inquiry about a warm roof design, this product can indeed be used in such a configuration, where it's installed above the structural deck and below the weatherproof layer. It's also commonly used between joists in a traditional cold roof setup. For more specific application details and to view standard installation diagrams, please refer to the Actis Hybris Installation Guide available at this link. Please note that for any specific construction scenarios like yours, it's recommended to consult a construction professional or your local building control office to ensure the insulation meets the required regulations and performance criteria.
Question:
How does this product compare to a rigid board such as celotex? Which thickness of Actis Hybris would provide a similar insulation performance to say 50mm celotex?
Answer:
The Actis Hybris Panel Reflective Multifoil Insulation is a different type of insulation compared to rigid board products like Celotex. It's lightweight and easy to install due to its multifoil structure, and it's designed to reflect heat back into the room, making it highly efficient. In terms of thermal performance comparison, Celotex and other rigid insulation boards work on the principle of trapped air within the foam structure, while Actis Hybris works by reflecting radiant heat. Therefore, it might not be directly comparable in terms of thickness. However, the Actis Hybris Panel Reflective Multifoil Insulation has a thickness of 90mm. This might provide a similar level of insulation, but it can depend on the specific conditions of the building where it's installed. For a more precise comparison, it's recommended to check with a construction professional or conduct a U-value calculation.

Question:
can this material be laid on top of existing fibreglass insulation across the ceiling joists? Is there a condensation risk?
Answer:
Provided the existing insulation is in good condition there is no reason to state why you couldnt combine the two together, please see the below guide for more info - https://www.insulationsuperstore.co.uk/user-guides-brochures/actis-hybris-installation-guide-dec21.html
