Is it Worth Insulating Under Floorboards?

Is it worth insulating under floorboards floorboards is a practical and cost-effective way to increase the thermal efficiency of your home, especially in warmer climates. It can also reduce draughts and make the living spaces in your home more comfortable, while adding a level of sound insulation. Often this is an easier option than putting insulation in the walls and ceiling, as it doesn’t require any re-painting of the walls or trimming of doors.

Underfloor insulation can be installed in modern homes with solid floors or in older buildings that have suspended timber floors. Traditionally, this has been achieved by placing rigid insulation boards between the floor joists. However, this can be difficult to achieve in older buildings as the joists aren’t always perfectly aligned and cutting the insulation to size can be tricky. It’s also important to consider the ventilation of your floor as if the insulation isn’t properly ventilated then moisture can penetrate the insulation and cause damp and interstitial condensation which will decrease its effectiveness.
