Up to first floor level and awaiting precast slabs form Creagh Concrete Products Ltd 👌

Time for quick chat on the detailed Low-Energy Drawings and initial steps required for the start of the air-tightness details. In this case the wrapping of the slabs with an air-tight membrane to stop leakage from the wall cavities into the heating spaces😃

Have you ever looked closely at the precast slab unit with the holes?? Imagine all them holes creating a network of tunnels, full of cold air direct from cavity to the centre of your house 🤔or worse, your nice warm heated air escaping out 😱

Therefore, wrapping the slab ends stops this completely🥳
