Specifiers

Make suspended floors part of every retrofit

Every whole-house retrofit should consider the floor. Yet suspended floors are still one of the most overlooked elements of retrofit, often excluded because they are perceived as complex, disruptive or difficult to treat.

In reality, they represent a significant opportunity to improve thermal performance, reduce draughts and increase resident comfort, without invasive underfloor insulation or major disruption.

AirEx Floorvent makes it easy for retrofit professionals to confidently include suspended floors in whole-house retrofit projects and Warm Homes funded schemes.

Whether you are working on individual homes or large-scale housing portfolios, Floorvent helps turn an often-overlooked measure into a practical, scalable part of retrofit delivery.

Designed for confident specification

We understand that a successful retrofit programme depends on solutions that are technically robust, easy to implement and efficient to model.

AirEx Floorvent is independently certified, recognised within industry standards, supported by comprehensive technical documentation, and being installed in Warm Home funded schemes, giving specifiers confidence that the measure can be incorporated into projects with minimal risk and without adding unnecessary complexity to the design process.

We provide everything needed to support specification, including:

BBA Certification
SAP and RdSAP modelling training
PAS 2030/35 compliance guidance
Technical data sheets and design guidance
Specification wording and technical support
Funding and eligibility guidance

AirEx Floorvent can typically deliver a 2-4 SAP point improvement, helping projects achieve EPC targets more efficiently while providing property and condition-specific underfloor ventilation for suspended floors.

Our technical team is also available to provide project-specific advice and modelling support, helping specifiers integrate suspended floor energy efficiency measures with confidence and ensuring suspended floors become a standard consideration rather than an exception within retrofit programmes.

From compliance to confidence

One of the biggest barriers to treating suspended floors is uncertainty around compliance, modelling and funding eligibility. We've worked to remove that complexity.

AirEx Floorvent can be modelled quickly using the official BRE Appendix Q API for SAP and RdSAP, enabling assessors and designers to accurately demonstrate the performance benefits within seconds across multiple heating systems and fuel types.

Alongside our technical resources, we provide practical guidance to help Retrofit Coordinators, Designers, Assessors and Surveyors understand where Floorvent fits within wider retrofit strategies and how it can contribute to better-performing, healthier homes.
