EnviroVent have launched a new and exciting technology called Dynamic PIV, a whole house ventilation system specifically tested by BRE to comply and work in-conjunction with Jablite’s Dynamic Cavity Insulation to achieve excellent DER points in SAP.

Intelligent 2 in 1 solution Dynamic PIV brings Dynamic Insulation and Positive Input Ventilation (PIV) together to offer builders and designers a new 2 in 1 solution to meet today’s ever increasing demands for energy efficiency and carbon reductions.

How does it work?
It works by capturing the heat energy that would normally escape from the dwelling and utilises it to heat up incoming air through the insulation layer, effectively turning the envelope of the building into a heat exchanger. What’s more, the temperature of the incoming air can be raised as much as 8°C. Situated in the loft space, the Dynamic PIV is connected to the cavity and works at a continuous rate to draw the warmed air (via the Dynamic insulation) into the property at ceiling level. Achieving a Specific Fan Power as low as 0.2 W/l/s along with significantly improved U-Values and Psi-Values, Dynamic PIV controls humidity levels and ensures all year round good indoor air quality.

This latest innovation offers developers, contractors and specifiers a cost effective alternative to heat recovery ventilation for new build and retrofit projects.
