New Hardwood Timber Sill Installation in Hurlstone Park
This new hardwood timber sill installation in Hurlstone Park restored the performance and appearance of a heritage home while preserving its original character. Heritage Specialists installed a new hardwood timber sill, custom timber sashes, acoustic glazing, and traditional window components to improve comfort, reduce outside noise, and enhance long-term durability without compromising the home’s architectural integrity.
New Hardwood Timber Sill Installation in Hurlstone Park
Maintaining the beauty of a heritage home often requires more than repairing worn timber. As windows and sills age, they can become susceptible to water damage, air leaks, poor insulation, and increased external noise. The challenge is finding a solution that upgrades the window’s performance without losing the traditional craftsmanship and architectural details that define the property.
For this project, Heritage Specialists completed a new hardwood timber sill installation in Hurlstone Park, along with significant window upgrades to both the bedroom and the combined living room and kitchen areas. Every element was carefully designed to retain the home’s original appearance while delivering noticeable improvements in comfort, acoustic performance, weather protection, and everyday usability.
Rather than replacing the home’s character with modern alternatives, we recreated and upgraded the existing timber windows using traditional joinery methods, premium materials, and carefully selected glazing solutions. The result is a transformation that respects the property’s heritage while providing the practical benefits expected from a modern restoration.
Project Overview
This project involved extensive restoration and upgrading of two key areas of the home.
Bedroom
The bedroom window received a complete sash upgrade while retaining the existing box frame.
Works included:
- Supplying and installing new top and bottom timber sashes
- Glazing with 6.76mm acoustic glass
- Installing four new wax-coated traditional cotton sash cords
- Correctly balancing the original sash weights
- Installing new timber beading with integrated draft and acoustic seals
- Supplying and installing new sash window hardware
Living Room and Kitchen
The living room and kitchen window required more substantial restoration.
Works included:
- Supplying and installing a new hardwood timber sill
- Installing waterproof flashing for long-term weather protection
- Manufacturing and installing a new three-light casement sash in primed vertical grain Western Red Cedar
- Glazing with 6.76mm acoustic glass and laminated coloured cathedral glass
- Traditional linseed oil putty glazing
- Installing new premium window hardware
Together, these upgrades significantly improved both the appearance and functionality of the home’s original timber windows.
A Complete Transformation Without Losing Heritage Character
One of the greatest successes of this project is how dramatically the windows were transformed while remaining faithful to the home’s original design.
Many older homes require window upgrades due to deterioration, but replacing original timber joinery with modern alternatives can permanently alter the property’s architectural character.
Instead, Heritage Specialists carefully recreated each component to maintain the traditional proportions, profiles, and detailing of the existing windows.
The completed installation looks entirely consistent with the home’s heritage style while delivering improvements that homeowners immediately notice every day.
From the street, the windows retain their timeless appearance.
Inside the home, however, the difference in comfort, operation, and acoustic performance is significant.
Bedroom Window Restoration
The bedroom window retained its existing box frame, preserving an important part of the original construction.
Rather than replacing the entire window assembly, Heritage Specialists supplied and installed new custom-built timber top and bottom sashes manufactured to fit the existing frame precisely.
This approach allows the home’s original character to remain intact while replacing the components that experience the greatest wear over time.
New sashes provide:
- Improved structural integrity
- Better weather resistance
- Smoother operation
- Longer service life
- A refreshed appearance consistent with the home’s original design
Improved Acoustic Performance with 6.76mm Acoustic Glass
A major focus of this project was reducing outside noise while maintaining the appearance of traditional timber windows.
The bedroom sashes were glazed using 6.76mm acoustic glass, specifically selected to improve sound insulation.
Acoustic laminated glass helps reduce the transmission of external noise, making bedrooms quieter and more comfortable throughout the day and night.
For homes located near busy roads, schools, public transport, or active neighbourhoods, this type of glazing can make a noticeable difference to everyday living.
Importantly, these acoustic improvements were achieved without altering the traditional appearance of the timber windows.
The home continues to retain its heritage aesthetic while providing a more peaceful indoor environment.
Traditional Sash Cords and Balanced Weights
The smooth operation of a traditional sash window depends on the quality of its balancing system.
For this project, Heritage Specialists installed four new wax-coated traditional cotton sash cords connected to correctly balanced sash weights.
Wax-coated cotton cords have long been trusted in heritage window construction because they combine durability with authentic appearance.
Correctly balancing the sash weights ensures:
- Smooth opening and closing
- Reduced strain on the hardware
- Easier everyday operation
- Longer service life
- Reliable performance for years to come
Maintaining the traditional counterweight system preserves both the authenticity and functionality of the original window design.
Better Insulation Through Modern Sealing Technology
Older timber windows commonly develop air gaps that allow drafts, dust, and outside noise to enter the home.
To improve overall performance, Heritage Specialists installed new timber beading incorporating integrated draft and acoustic seals.
These discreet seals provide several practical benefits.
They help reduce unwanted air infiltration, improve thermal efficiency, minimise rattling, and further enhance the acoustic performance of the window.
Because the seals are integrated within the timber beading, they remain virtually invisible once installed.
This allows the window to maintain its traditional appearance while performing to a much higher standard than older untreated timber windows.
New Window Hardware for Reliable Operation
To complete the bedroom restoration, new sash window hardware was supplied and installed.
High-quality hardware not only improves reliability but also complements the appearance of traditional timber joinery.
Carefully selected fittings ensure the restored windows continue operating smoothly while matching the heritage character of the property.
New Hardwood Timber Sill Installation
The centrepiece of this project was the new hardwood timber sill installation in Hurlstone Park.
Window sills play an essential role in protecting timber windows from moisture.
Over time, prolonged exposure to weather can cause timber sills to deteriorate, creating opportunities for water ingress and structural damage.
Rather than applying temporary repairs, Heritage Specialists supplied and installed a completely new hardwood timber sill designed for long-term durability.
Hardwood provides excellent strength and resistance to everyday wear, making it an ideal choice for external timber window construction.
The completed sill restores both the appearance and structural integrity of the window while preserving the home’s traditional architectural detailing.
Added Protection with Waterproof Flashing
To maximise the lifespan of the new timber sill, waterproof flashing was incorporated into the installation.
Flashing helps divert rainwater away from vulnerable timber joints, reducing the likelihood of moisture penetration over time.
This additional protection helps:
- Extend the life of the timber sill
- Reduce maintenance requirements
- Protect surrounding timber components
- Improve long-term weather resistance
Although hidden from view, proper flashing is one of the most important elements of a high-quality timber window installation.
Custom Three-Light Casement Window
The living room and kitchen also received a new three-light casement sash manufactured from primed vertical grain Western Red Cedar.
Western Red Cedar remains one of the preferred timbers for heritage joinery due to its:
- Excellent dimensional stability
- Natural resistance to decay
- Attractive grain
- Lightweight strength
- Long-term durability
Every casement sash was custom manufactured to match the proportions and detailing of the home’s original windows, ensuring the finished installation blends seamlessly with the existing architecture.
Combining Acoustic Glass with Decorative Cathedral Glass
This project demonstrates how heritage aesthetics and modern performance can work together.
The new casement sash was glazed using a combination of:
- 6.76mm acoustic laminated glass
- Laminated coloured cathedral glass
The acoustic glazing improves interior comfort by reducing external noise, while the coloured cathedral glass preserves the decorative character often associated with traditional homes.
This combination allows the window to continue serving as an architectural feature while delivering the practical benefits of modern glazing technology.
Finished with Traditional Linseed Oil Putty
To maintain authenticity, the glazing was completed using traditional linseed oil putty.
Linseed oil putty has been used for generations in heritage window construction because it accommodates natural timber movement while creating the classic glazing profile expected in traditional timber windows.
Using traditional finishing methods ensures the completed window remains visually consistent with the property’s original period detailing.
Noticeably Quieter Living Spaces
One of the most significant outcomes of this project is the improvement in acoustic comfort.
Both the bedroom and living areas now benefit from upgraded acoustic glazing and integrated sealing systems that help reduce external noise entering the home.
Whether the property experiences nearby traffic, neighbourhood activity, or environmental noise, these improvements contribute to a noticeably quieter and more relaxing indoor environment.
Better acoustic performance is often one of the first benefits homeowners notice after completing a heritage window upgrade.
Improved Energy Efficiency and Everyday Comfort
Although preserving the home’s original appearance remained a priority, the completed installation also delivers meaningful improvements in everyday comfort.
The combination of acoustic glass, integrated draft seals, properly fitted timber joinery, and quality installation helps reduce unwanted air movement through the windows.
Benefits include:
- Reduced drafts
- Better thermal insulation
- Improved indoor comfort
- Less reliance on heating and cooling
- More consistent internal temperatures
These upgrades allow the home to retain its heritage charm while performing more like a modern residence.
Preserving Character Through Traditional Craftsmanship
Every restoration project undertaken by Heritage Specialists aims to protect the architectural integrity of the property.
Rather than replacing original features with generic modern products, we recreate traditional timber windows using time-tested joinery methods, premium materials, and authentic detailing.
This philosophy ensures every project maintains the unique character that makes heritage homes so valuable.
The completed installation demonstrates how thoughtful restoration can enhance performance while respecting the home’s history.
