Can you have too much insulation in your loft? As long as you ventilate your property properly, you can have as much insulation as you like within reason. The trick with loft insulation is to balance the amount of insulation you have with the amount of ventilation necessary to prevent damp. As long as you get that balance right, you should be fine.
What happens if your house is too air tight? Airtight house construction succeeded in decreasing energy costs, but most building science at the time hadn’t considered the potential disadvantage of such a tightly sealed house: poor ventilation in houses can actually also cause moisture buildup, leading to mold and IAQ issues.
