Draught proof, draught proof, draught proof

As awareness of energy efficiency grows, draught proofing has become essential. Whether you live in a cold climate where keeping heat in is vital, or a warmer area like Sydney — which surprisingly experiences chilly days — sealing your windows is key to maintaining comfort and reducing energy costs. Plus, it helps keep out unwanted smoke and dust.

How our draught sealing system works

Our system uses high-quality brush pile seals fitted around the entire perimeter of your sash windows — including the top of the top sash, meeting rails, lower rail of the bottom sash, parting bead, and staff bead — creating a complete airtight barrier.

The benefits of draught proofing

Draught proofing is one of the most effective upgrades you can make to your home. When combined with proper maintenance — such as addressing wood rot and using quality sash window cords, pulleys, or spiral balances — your sash windows can last for decades.

Preserving tradition & sustainability

There's a common misconception that old windows are inefficient and new windows are always better. However, many historic Georgian and Victorian sash windows have stood the test of time, showcasing their durability and sustainability. Modern windows, by contrast, often have shorter lifespans and can detract from the character of traditional buildings.

With proper care, traditional sash windows can outperform modern replacements, offering both aesthetic charm and excellent performance.

Maximise your thermal efficiency

Draught proofing your sash windows delivers one of the best returns on investment when it comes to improving your home's thermal efficiency. Many homeowners spend thousands on double or triple glazing, yet neglect sealing the gaps around their windows — rendering their investment far less effective.

"Upgrading your glass without sealing air leaks is like putting a band-aid on a leaky pipe."
