Sealasash recently completed one a large heritage projects; the Philip Smith Centre in Hobart, Tasmania. Built in 1911, this significant property required careful, detailed work to preserve its historic fabric while improving comfort and efficiency for modern use. Over a period of seven weeks, our team carried out an extensive draught sealing Hobart project across the building’s windows and doors – a challenge that combined scale, tradition, and technical expertise.
The Scope – 79 Sash Windows and 62 Opening Lights
The Philip Smith Centre features a remarkable collection of timber windows, all of which had deteriorated over time. Cold draughts, rattles, and inefficient operation were affecting the building’s comfort and performance.
Our project scope included:
- Draught sealing 79 double-hung sash windows
- Draught sealing 62 opening lights
- Traditional carpentry repairs to timber joinery
- Ensuring heritage details were preserved at every stage
The work required patience, skill, and respect for the original 1911 craftsmanship. Each sash and frame was carefully restored, sealed, and tested, ensuring the building’s character was retained while the comfort was drastically improved.
Collaboration with Industry Leaders
Sealasash were proud to be subcontracted by Hansen Yuncken, one of Australia’s leading commercial builders, to deliver this heritage upgrade. The project was specified by heritage architects Lovell Chen, who entrusted our team with the responsibility of ensuring the work was carried out in line with conservation principles.
Working alongside such respected names highlights the value of our specialised expertise in heritage timber window restoration and draught sealing.
Why Draught Sealing Matters in Heritage Projects
Heritage buildings like the Philip Smith Centre are defined by their windows – but original joinery rarely offers the comfort modern users expect. Draught sealing is one of the most effective ways to upgrade these windows without replacing them, keeping the historic character intact.
As noted in our Simple Solutions Work article, sealing is a straightforward but highly effective way to cut energy loss, reduce noise, and extend the life of timber joinery. Combined with careful carpentry repairs, the result is a warmer, quieter, and more sustainable building.
The Result – Comfort with Conservation
After seven weeks of meticulous work, the Philip Smith Centre now benefits from:
- 79 restored sash windows and 62 sealed opening lights
- Draught-free comfort throughout the building
- Retained heritage detailing with discreet modern improvements
- Traditional carpentry repairs that strengthened and preserved the joinery
This draught sealing Hobart project demonstrates how modern performance can be achieved without sacrificing heritage. By combining traditional methods with proven sealing systems, Sealasash helped preserve a 1911 landmark for the next generation.
