Which Flush Casement Window Range Suits Listed Buildings and Conservation Areas?

For specifiers working on projects in listed buildings and conservation areas, our Richmond Flush Casement in the Heritage Range is the perfect choice. These windows are designed to replicate the authentic look of period windows while incorporating modern features for enhanced performance. Key features include:

  • Authentic Design: Faithful reproduction of traditional timber windows with historically accurate details.
  • High Performance: Enhanced thermal efficiency and weather resistance without compromising on aesthetic appeal.
  • Custom Finishes: A variety of finishes to match existing architectural details and historical requirements, aiding in planning permission approvals.

What Makes the Hardwick Flush Casement in the Classic Range a Great Choice?

For those seeking a balance between aesthetics and cost, our Hardwick Flush Casement in the Classic Range offers an excellent solution. This range provides beautiful design at a more accessible price point. Highlights include:

  • Timeless Design: Suits a variety of project styles with a classic appeal.
  • Cost-Effective: High-quality windows at a lower price point.
  • Double Glazing: Efficient double glazing for good thermal performance.
  • Longevity: Made from Red Grandis, offering a lifespan of over 60 years and resulting in negative emissions as the carbon dioxide absorbed by the timber during growth outweighs the emissions generated during the raw material extraction.

How Does the Acadia Flush Casement in the Frontier Range Excel in Performance?

Our Acadia Flush Casement in the Frontier Range is perfect for projects with Net Zero ambitions, working towards PassivHaus and Enerphit standards. This range is designed for ultimate performance and sustainability, featuring:

  • Advanced Insulation: Proprietary vacuum cavity unit for superior thermal efficiency.
  • Energy Efficiency: Working towards meeting the stringent requirements of PassivHaus and Enerphit standards, which take a whole building approach where high-performance windows are a key component.
  • Eco-Friendly Materials: Sustainably sourced materials with EPD documentation.
  • Longevity: Made from Accoya, providing an exceptional lifespan of over 70-80 years.

Environmental Impact Comparison

Choosing Gowercroft windows means prioritising sustainability. Our dedication to sustainability is well-documented, as evidenced by a robust Life Cycle Assessment (LCA) study conducted in collaboration with the University of Derby’s ERDF Low Carbon Programme. This study utilised the Building Resource Establishment (BRE) online LINA tool for a ‘cradle to gate’ LCA, covering raw material extraction, transport, and manufacturing stages (A1-A5). The study highlights the environmental advantages of our flush casement window range:

  • Lower Emissions: Our Hardwick, Richmond, and Acadia flush casement windows demonstrate significantly lower greenhouse gas emissions compared to similar products. This includes windows made from aluminium, uPVC, and other timber windows such as those from Mumford and Wood.
  • Sustainable Timber: The Hardwick Flush Casement window in Red Grandis timber shows negative emissions at the raw material stage, thanks to the carbon absorption during the growth of the hardwood. This is a testament to our efficient, eco-friendly manufacturing processes and the sustainable sourcing of our materials.

The following graph illustrates the global warming potential of our three flush casement window ranges compared to other materials, including a comparable timber window from Mumford and Wood:

Window TypeGlobal Warming Potential (kg CO2e)
Hardwick Flush Casement (Red Grandis)-10
Richmond Flush Casement (Accoya)20
Acadia Flush Casement (Accoya)15
Mumford and Wood Timber Window30
Aluminium Window200
uPVC Window250

This comparison highlights the superior sustainability of Gowercroft windows, especially in terms of lower greenhouse gas emissions.

How Do Gowercroft Windows Compare in Sustainability?

  • Lower Emissions: Gowercroft timber windows have significantly lower greenhouse gas emissions during manufacturing compared to aluminium and uPVC windows.
  • Carbon Absorption: Our hardwood windows, such as the Hardwick Flush Casement, absorb more CO2 during their growth than they emit during production, resulting in negative emissions.
  • Longevity: The Hardwick Flush Casement in Red Grandis offers a lifespan of over 60 years, while the Richmond and Acadia Flush Casements in Accoya provide an exceptional longevity of over 70-80 years.
  • Efficient Manufacturing: The efficient processes at Gowercroft Joinery ensure minimal environmental impact during the manufacturing stages.
