Suspended Floor Insulation

Suspended timber floors are common in older Irish homes — Georgian, Victorian, and early 20th-century properties often sit above a ventilated void designed to prevent damp. While effective in its time, this open airflow leaves rooms cold, draughty, and difficult to heat.

At Dada Flooring, we specialise in restoring warmth and efficiency to these period homes without compromising the building’s structure or character. Our insulation process is carefully tailored to ensure breathability, longevity, and a flawless finish.

Our Process: Detailed, Careful, and Built to Last

1. Lifting & Assessing the Existing Floor

We gently remove the original boards by hand, preserving as much of the existing timber as possible. Older floors can be fragile — our approach avoids unnecessary damage and ensures the boards are returned exactly as they were.

2. Installing a Breathable Membrane

A specialist breathable membrane is fitted across the joists.
This layer:

Blocks draughts coming up from the void
Prevents dust and cold air entering the home
Allows essential ventilation underneath, protecting joists from moisture

It’s the balance that older homes need: airtight above, ventilated below.

3. Fitting High-Quality Insulation

We install insulation between the joists — sized and cut precisely for a perfect fit.
Options include:

Rigid insulation boards
Mineral wool batts
Natural fibre/eco-friendly insulation

Each choice improves thermal comfort, reduces heating costs, and keeps the room warmer throughout the year.

4. Reinstalling & Repairing the Floorboards

Once insulated, we refit the floorboards with care. Any boards that are too damaged to go back are replaced with reclaimed timber chosen specifically to match:
