Passivhaus and EnerPHit windows in Rhyl
From the first measure to the handover pack, we handle Passivhaus and EnerPHit windows for homes in Rhyl and the rest of Clwyd.

The windows and installation detail low-energy builds depend on. Passivhaus is a building standard from the Passive House Institute; EnerPHit is its version for retrofits.
Winter light and glass choice in Rhyl
On the shortest day, Rhyl gets about 7 h 30 min of daylight and the midday sun reaches only about 13° above the horizon. Low winter sun means north-facing rooms here gain little solar heat, which is where triple glazing’s lower heat loss helps most.

Rules for Passivhaus and EnerPHit in Wales
In Wales, replacement windows must meet 1.4 W/m²K, or a Window Energy Rating of band B or better. As in England, replacement windows are a controlled fitting: a competent person scheme installer self-certifies the work, or building control approves it.
Planning: Householder permitted development rules do not cover flats, and councils can remove rights with Article 4 directions. Listed buildings need listed building consent. Check with your council before changing the style or material.
