Accoya vs Hardwood – how to choose timber windows

If you’re considering a set of timber windows for your home, you may be wondering which is the best wood for you. Accoya and hardwood are two fantastic options for timber windows, however they possess different qualities. Understanding these qualities is important for determining which is the right option for you.


Hardwoods are usually denser than softwoods and tend to provide higher levels of strength, weather resistance and durability. This means they’re ideal for external applications, including windows, as they undergo continuous weather exposure. They also require less maintenance than cheaper softwoods. However, they’re usually more expensive than softwoods because they grow at a slower rate and take longer to dry.

Accoya wood

Accoya wood is traditionally a softwood, which tend to be less durable and require more maintenance than hardwoods. However, softwoods tend to develop quicker than hardwoods, meaning they’re cheaper to manufacture. Accoya wood is different to traditional softwoods, possessing a number of important qualities found on hardwoods.

Accoya windows

The qualities of Accoya windows are listed below, several of which demonstrate how Accoya differs from traditional softwoods.Accoya oak timber windows

  • When used in external applications, Accoya is guaranteed for 50 years. It will also last with only minimal amounts of maintenance.
  • The dimensional stability of Accoya is incredible, whilst it’s highly resistant to shrinkage and swelling.
  • Available in various styles, including sliding sash and casement, Accoya windows are suitable for a huge variety of applications.
  • Accoya wood is relatively light in colour, meaning an impressive selection of finishes can be successfully applied to it. This includes those with translucent stains.
  • It’s ultra-sustainable, combining the carbon benefits of softwoods with the durability of hardwoods. This is exemplified by its C2C Gold accreditation. This means it’s ideal for homeowners looking to be as eco-friendly as possible.
  • The thermal qualities of Accoya windows are exceptional, keeping homes cool in the summer and warm in the winter. This provides homeowners with significant potential to save on energy bills.

Hardwood windows

Here at Reddish Joinery, our hardwood timber windows are constructed from African Sapele. Their benefits include:Single timber sliding sash window

  • Due to its lack of permeability, African Sapele is resistant to treatment. As a result, windows constructed from it require treating less frequently than other timbers.
  • Timber is a naturally good insulator, plus our hardwood windows are fitted with Pilkington double glazed units. This means they perform very well in terms of thermal efficiency.
  • Naturally, African Sapele is a beautiful dark reddish brown colour, which is perfect for heritage properties and those in conservation areas. However, transparent coatings and colours take to it well, allowing it to fulfil a range of aesthetic desires.
