HYBRIS Insulation Installers for Lofts and Suspended Floors

Improve your home’s energy efficiency with professionally installed ACTIS HYBRIS insulation. We install HYBRIS reflective insulation in lofts, pitched roofs and suspended timber floors across the UK, with a free survey to assess your property and recommend the most suitable installation.

Why Choose HYBRIS Insulation?

HYBRIS is a high-performance reflective insulation system suitable for lofts, pitched roofs and suspended timber floors. Its structured honeycomb design traps air within multiple layers, providing effective thermal performance while remaining lightweight and flexible.

Unlike traditional mineral wool insulation, HYBRIS contains no irritating fibres and is designed to retain its shape over time. Its reflective outer layers also contribute to airtightness and vapour resistance when installed as part of the correct system.

HYBRIS is particularly useful where available depth is limited, allowing us to provide effective insulation without relying on the greater material thickness typically associated with traditional mineral wool.

During your free survey, we’ll assess the construction, existing insulation and ventilation before recommending the appropriate HYBRIS thickness and installation method for your property.

Where additional roof ventilation is required, we can also install loft lap vents to help maintain suitable airflow through the roof space.

HYBRIS Thermal Performance

HYBRIS Thermal Performance

HYBRIS is available in a range of thicknesses to suit different applications and construction requirements. We assess each property before recommending the most appropriate HYBRIS system and thickness.

The thermal resistance (R-value) of HYBRIS increases with thickness. A higher R-value provides greater resistance to heat flow, helping to reduce heat loss when the insulation is installed as part of a correctly designed system.

Because HYBRIS can provide strong thermal performance without requiring the depth associated with some traditional insulation materials, it can be particularly useful where available space is limited. This includes pitched roofs, rafters and suspended timber floors.

During your free survey, we’ll assess the construction, available depth, existing insulation and ventilation before recommending the most suitable installation for your property. The table shows the core thermal resistance across the HYBRIS thickness range.

Is HYBRIS Right for Your Home?

HYBRIS can be a strong choice where good thermal performance is needed without the depth required by some traditional insulation systems.

It is particularly suitable for pitched roofs, loft rooms, skeilings and suspended timber floors, where the available space between rafters or joists may be limited. Its lightweight, flexible structure allows it to fit closely between structural timbers while retaining its shape over time.

However, HYBRIS isn’t automatically the right insulation for every property. The best solution depends on the construction, available space, existing insulation and ventilation. During your free survey, we’ll assess these factors and explain whether HYBRIS or another insulation system is the most appropriate option for your home.

Hybris Insulation FAQ

HYBRIS is a reflective insulation system manufactured by ACTIS. It uses a structured honeycomb core with reflective outer layers to trap air and reduce heat transfer. The panels are lightweight, contain no irritating fibres and are designed to retain their shape over time.

Yes. We provide free, no-obligation surveys for homeowners considering HYBRIS insulation.

During the survey, we’ll assess the construction, available space, existing insulation and ventilation before discussing the most suitable options for your property. You’ll then receive a written quotation, with no requirement to sign on the day and no pressure to proceed.

Yes. HYBRIS can be installed between the joists of suspended timber floors to help reduce heat loss through the floor. Its lightweight, flexible structure allows it to fit closely between the timbers while providing strong thermal performance without requiring excessive depth.

The condition of the floor structure, available space, ventilation and access all need to be considered before installation. We assess these during the free survey and recommend the most appropriate insulation system for the property.

Neither system is automatically better for every property. HYBRIS provides strong thermal performance without requiring the depth associated with some traditional insulation materials, while mineral-wool insulation can be a practical and cost-effective option in open loft spaces.

Our surveyor will explain which system is better suited to the construction, available space and intended use of your loft or floor.

The cost of HYBRIS insulation installation depends on the size and construction of the space, the required insulation thickness, access and whether existing insulation needs to be removed.

We provide a free property survey followed by a written quotation, so you know the full cost before deciding whether to proceed. There is no requirement to sign or make a decision during the survey.

Yes. Where required, we can remove existing loft insulation before installing HYBRIS. This may be recommended where the existing insulation is old, damaged, contaminated or unsuitable for the proposed installation.

During the survey, we’ll assess the condition of your existing insulation and explain whether it can remain in place or should be removed. Any insulation we remove will be transported and disposed of appropriately by us as licensed waste carriers.

Installation time depends on the size and accessibility of the area, the construction of the property and whether any existing insulation must first be removed.

Once the property has been surveyed, we can explain the work involved and provide a more accurate expected timescale with your quotation.

The ventilation requirements depend on the construction of the property and where the HYBRIS insulation is being installed. Maintaining appropriate airflow and managing moisture are important parts of a correctly designed insulation system.

During the survey, we’ll assess the existing ventilation and the proposed installation. Where additional roof ventilation is required, we can install lap vents as part of the work.

Yes. Following completion of your HYBRIS installation, we’ll provide the relevant installation paperwork and certification.

Applicable workmanship and manufacturer warranties are also provided, depending on the installation. Eligible installations may also include an insurance-backed guarantee through HomePro.

Yes. We provide free, no-obligation surveys for homeowners considering HYBRIS insulation.

During the survey, we’ll assess the construction, available space, existing insulation and ventilation before discussing the most suitable options for your property. You’ll then receive a written quotation, with no requirement to sign on the day and no pressure to proceed.
