New Actis Eolis HC insulation - a how to guide for loft and barn converters

The first tranche of builders and specifiers to use a new style of insulation created by the manufacturers of the popular Actis Hybrid range have been delighted with its ease of use and functionality.

They’re finding that installing Eolis HC – a two-in-one reflective insulation with an integrated vapour barrier - is twice as quick as using traditional alternatives.

They say it’s transforming their experience of insulating lofts and barn conversions, not least because fewer steps are required for them to achieve an impressive U-value and airtightness.

The revolutionary Triplex technology at its core means Eolis HC is especially useful for installers dealing with shallow rafters where headroom is at a premium. Part of the reason for this, in addition to the thinness of the product, is because it doesn’t require the usual 25mm air gap to avoid condensation – at least for most locations throughout the UK.

Using Eolis HC instead of PIR board means there’s no need to cut insulation between each rafter. Instead, installers can just lay the product across the rafters on the inside (warm side) of the building, sealing each section to the next with an integrated self-adhesive lap.

The easiest way to learn how to install Eolis HC is to watch a step-by-step how to video. As well as an overview showing the start to finish process from unpacking to plasterboard, there are also mini, bitesize snippets showing how to cut the product, how to insert electrical wires and pipes through the Eolis HC and how to cut round doors and windows.
