Draught Proofing FAQs
Frequently Asked Questions
How do I calculate how much beading I need?
To calculate the amount of stop or staff bead required:
- Measure the perimeter of the window frame (height x 2 + width x 2).
- Add at least 100mm extra to each measurement to allow for mitre cuts.
For parting bead:
- Measure vertically from the window sill to the top of the frame.
- Multiply this by two, as parting bead is needed on both sides of the window.
Can I seal the meeting rail?
Yes. Install a pile and brush carrier routed into the meeting rail on the bottom sash. These come in 1-metre lengths, generally enough for most windows.
Can I seal the gap at the top of the top sash?
Yes, either by routing in a pile and brush carrier (same as for the meeting rail) or by installing a piece of Ecobead parting bead at the top sash. Unsure? Contact us for advice.
Do I need to draught proof the parting bead as well as the stop bead?
Absolutely. The parting bead separates the sashes vertically and must be sealed completely to avoid significant heat loss or draughts. Skipping this step compromises the effectiveness of the whole installation.
Will I be able to see Ecobead once installed?
No. When the window is closed, Ecobead is invisible. When open, only neat draught seals protrude slightly, providing a clean, integrated finish without unsightly stick-on strips.

Is Ecobead right for me?
If you have double hung sash windows that rattle, leak, or let in draughts, smoke, or noise, Ecobead is an excellent choice. Many customers are amazed by the difference it makes.
When should I not use Ecobead?
If your windows are in very poor condition (rotting timber, broken cords, or severely damaged), we recommend repairing these issues before installing Ecobead.
Can I use Ecobead on doors?
No, Ecobead is designed specifically for double hung sash windows. For doors, please see our Aquamac AQ21 product.
Can I use Ecobead on casement windows?
No, Ecobead is made exclusively for double hung sash windows. For casement windows, the Aquamac AQ21 is recommended.
Why does Ecobead use brush seals instead of foam?
Brush seals outperform foam because foam deteriorates faster, especially when damp or compressed. Brush pile adapts better to uneven gaps, making it more effective for older windows.
Will Ecobead need painting?
Timber parts come undercoated with Dulux 3-in-1 white paint and will need finishing coats to match your windows. Light sanding and filling of nail holes may be necessary. Avoid getting paint on the brush seal as it reduces effectiveness.
