Achieving 7-Star Performance With Timber Windows and Doors


In the quest for energy-efficient homes that perform to the standard of the updated National Construction Code (NCC), the role of timber windows and doors cannot be underestimated.

Their natural insulating properties and minimal thermal bridging make them an asset in achieving a 7-star Nationwide House Energy Rating Scheme (NatHERS) rating. By carefully selecting, designing, and installing timber windows and doors with high-quality glazing choices, builders can simultaneously contribute to more environmentally friendly and comfortable constructions for their own customers in the process.

So just how exactly can timber windows and doors help you achieve this performance?

The Role of Timber Windows and Doors in Achieving a 7-Star Rating.

  1. Natural Insulation: Timber possesses inherent insulating properties, making it an excellent material for windows and doors. It has a low thermal conductivity, meaning it does not readily transfer heat or cold from the outside to the interior, insulating twice as well as aluminium and up to 400 times better than steel. This natural insulation helps maintain a stable indoor temperature, reducing the need for constant heating or cooling and contributing to a higher energy efficiency rating.

  2. Minimised Thermal Bridging: Timber frames are less prone to thermal bridging compared to their metal counterparts. Thermal bridging occurs when there is a direct pathway for heat to flow through the building envelope, leading to energy loss. The use of timber windows and doors can help minimise this effect, ensuring that the building envelope remains intact and efficient.

  3. Low Environmental Impact: Timber is a renewable resource that can be sustainably harvested and sourced from responsibly managed forests. Choosing timber windows and doors aligns with eco-friendly construction practices, contributing to a reduced carbon footprint and a more environmentally conscious building.

  4. Enhanced Daylighting and Ventilation: Properly designed timber windows and doors can facilitate ample natural daylighting and ventilation. This reduces the need for artificial lighting during the day and promotes better indoor air quality, factors that contribute positively to energy efficiency and overall inhabitant well-being.


Implementation Tips

To effectively harness the benefits of timber windows and doors for achieving a 7-star NatHERS energy efficiency rating, builders should consider the following:

  1. Material Selection: Seek out high-quality timber species known for their durability and insulation properties.

  2. Design Considerations: Collaborate with architects and designers to incorporate well-placed windows and doors that optimise natural lighting and ventilation while minimising potential heat gain or loss.

  3. Professional Installation: Ensure precise installation by skilled craftsmen to guarantee airtightness and optimal thermal performance. Proper sealing and weather stripping are essential to prevent drafts and energy leakage.

  4. Glazing Options: Select energy-efficient glazing that complements the timber frames. Double glazing with low emissivity coatings can significantly enhance insulation and further contribute to energy efficiency.
