Why Choose Accoya?

Accoya wood

What is it?

Accoya wood is produced from sustainably sourced, fast growing wood using a non-toxic modification process from the surface to the core.  The result is a durable, stable, reliable and beautiful solid wood with the performance characteristics of the most durable tropical hardwoods but offering very valuable environmental credentials.  Accoya can be used to produce beautiful, custom-made joinery products, such as windows and doors, that are low maintenance, highly stable and can be expected to match or even exceed the performance durable hardwoods such as oak, teak, iroko and sapele……..

Ten good reasons to choose Accoya:

1.Durable – your joinery will stand the test of time and not require replacement for a least 60 years.

2.Beautiful natural product which can be recoated, repaired or recycled at the end of its useful life.

3.Stable –  windows and doors will be resistant to swelling or shrinkage

4.Low maintenance – factory coated products are guaranteed for 10 years.

5.Sustainable – by enhancing the durability and stability of a fast growing, abundantly available timber, Accoya has a significant environmental advantage over slow growing hardwoods which are often limited in their sustainable supply.

6.Non-toxic – the acetylation process used to alter the molecular structure of the timber to create Accoya is non toxic unlike other preparations and processes used to preserve hardwoods and softwoods.

7.100% recyclable

8.Naturally insulating – significantly improved thermal insulation qualities over most hardwoods.

9.Versatile – it can be opaque, transculent or transparent coated with water based finishes which can last up to three times longer.

10.Tried and tested – Accoya has been tested over prolonged periods in all types of weathering conditions – above ground, below ground and even in water.

Parsons Joinery have successfully completed the Accoya Certification Scheme which means that we have a full understanding of the manufacturing process and the correct use of ancillary materials, finishes and ironmongery.

WHY WOOD – eight good reasons to choose timber

Investing in replacement windows and/or doors for your home takes careful consideration and you need to feel confident that the choices you make are going to give you good value for money – why choose wood?



BEAUTY AND QUALITY – First and foremost, wood is naturally beautiful, adding character and warmth to your property and often value too.

DURABILITY – A good quality wooden window or door will, with careful maintenance, last a lifetime and a fully factory finished piece of joinery should give up to 10 years of life before it requires recoating.

SUSTAINABILITY – wood is a natural product and is endlessly renewable through recycling and renewable energy.

VERSATILITY – wooden joinery can be painted to change its appearance to match your current decorating scheme. Wooden joinery can be renovated and repaired.

VALUE FOR MONEY – when compared with other high quality construction materials.

AUTHENTICITY – the best choice for period properties as it replaces like for like and can be moulded to replicate original features.

ENVIRONMENTALLY FRIENDLY – growing trees absorb emissions. Each tonne of timber used instead of other building materials saves around a tonne of carbon dioxide. Timber products are biodegradable, rotting away naturally when they come to the end of their lifespan.

PRACTICALITY – wooden windows and doors can be manufactured to incorporate modern thermally efficient glass and security ironmongery.

RED GRANDIS – Sustainable, durable, cost effective

Here at Parsons Joinery we are constantly researching alternative timbers and processes to offer cost effective joinery solutions to our customers. Most recently, we have been working with a South American timber called Red Grandis, a member of the Eucalyptus family.

We use a variety of hardwoods including utile and European oak for their beauty, versatility and durability but what most attracted us to this particular timber was it’s incredible credentials as it is Pure (100%) FSC certified.
FSC certification reflects the proper use of forestry resources through regulation which ensure that plantations are well managed with consideration for people, workers, wildlife and the environment.
Whilst working with Red Grandis in the machine shop, it has proved to be a high-grade, clear timber with superior consistency in colour, appearance, grain and workability and can be stained or painted or left untreated to weather to an attractive silver grey colour. In fact, Red Grandis can be stained to resemble other species such as oak, offering a very attractive and cost effective alternative.
To view a sample window, please call us to arrange a visit to our showroom.
Why choose Red Grandis?
  • Responsibly sourced
  • FSC pure
  • Cost effective alternative to other hardwoods
  • Sustainable
  • Plantation grown
  • Durable and fungui resistant
  • Outstanding structural stability
  • Uniform in colour, appearance and grain
  • High quality finish
  • High end product at an affordable price
  • Can be stained to resemble oak

Supreme Innovation Award for Accoya

Timber expo accoya wood award

Accoya® and Medite® Tricoya® Win Supreme Innovation Award at this year’s Timber Expo in the UK.

UK Timber Industry Experts recognise high performance and innovative products

Revolutionary products Accoya® wood and Medite® Tricoya® panels have won the top award at this year’s Timber Expo 2012.

The innovative and high performance wood based products scooped the show’s Supreme Award for Innovation – a prestigious award which recognises a ‘product of solution that, in the eyes of the judges, stands out above all other innovations at the show.’

The award – for both Accoya Wood and wood-based panel product Medite Tricoya – reflects the outstanding levels of performance, stability and durability produced by the wood’s advanced acetylation technology through Accsys Technologies proprietary wood modification process.

Announcing their winning commendation the judges, who were made up of the UK’s leading timber experts stated that both Accoya and Medite Tricoya products are:  “truly ground-breaking and that the campaign to bring this technology to the marketplace has been very strategic and professionally managed.

The judges added that they felt that the “degree of product innovation, marketing and communication meant that Accsys and Medite through the joint development agreement deserved the Supreme Award for Innovation at this years’ show.”

Accoya produced in Europe by Accsys Technologies and the latest Medite Tricoya panel product produced by Coillte Panel Products are some of the most advanced wood products on the market and uses the latest in wood acetylation technology to deliver outstanding levels of performance, stability and durability.

These products are the result of more than 80 years research and development on wood acetylation which takes sustainably-sourced, fast growing softwood and non durable hardwoods and, in a non toxic process creates a new durable, stable and beautiful product that offers the very best environmental credentials.

Welcoming the awards, Bryan Crennell, Director of Sales and Marketing from Accsys Technologies said: “This is just the latest in a succession of industry awards and third part independent validation for both Accoya and Medite Tricoya across the world which recognises the huge progress we and Medite, through our joint development agreement have made in bringing these products to market over the last few years.

“We are now providing architects, specifiers, builders and contractors with new, innovative and high performance wood products and panel solutions which match and exceed the properties of the best tropical hardwoods that are ideally suited for exterior use.”

Peter Clifton, Product Manager for Medite Tricoya at Coillte Panel Products said “We are really pleased to have been recognised for the extremely hard work that has been put in to the launch and subsequent development of Medite Tricoya. This award reinforces the course that we are taking to present this unique product to the various sectors in which it can be used.”

Winter Checklist

Autumn and spring are the ideal times, just before the weather turns colder, to give your home some last minute routine maintenance in order to avoid costly repairs and replacements in the future. To keep your house in the peak of condition there are certain inspections and maintenance tasks that need to be undertaken periodically and it is considered good practice to create a maintenance routine to care for your home, checking off and dating tasks as they are completed.

By maintaining the structure, appearance and operation of your home you will retain or even enhance its value. If you are fortunate, this may only involve some routine DIY  visual checks, cleaning gutters and drains and clearing the seemingly never-ending autumn debris and leaves, all of which can be performed by the family on a clear bright day. However, some may require professional assistance which can be perceived as expensive but will, ultimately, save fortunes on costly repairs and replacements or even emergency call outs.

Whilst we may be quite thorough about periodic maintenance that involves the interior of our houses, cleaning and vacuuming and ensuring that our electrical appliances and heating are regularly checked and serviced, the exterior of our properties can suffer from neglect as the resulting damage caused by poor maintenance may take some time to emerge.  Such neglect can create an emergency situation when roofs leak during heavy rainfall, gutters or drains become blocked creating flooding and water penetration and unchecked paintwork can make your home susceptible to expensive rot, fungal attack and decay.

To ensure longevity of service, the exterior joinery on your property should be the subject of regular maintenance and inspection, most especially at the beginning and end of winter when damage by rain, wind and sun may become evident.  The most important elements to maintain on your windows and doors are the coating system and the hardware although we would advise checking and cleaning the entire unit, internally and externally, including the glazing unit and weatherseals for any sign of deterioration.  Water penetration in wood beyond the exterior coating will result in fungal attack, rot and decay and, therefore, a painted or stained finish should be repaired or re-applied once this becomes compromised.  Please refer to our guide to Joinery Maintenance for further information and guidance.

The advantage of timber joinery is that it can be repaired by a carpenter on site if the damage is not significant but prevention is always better (and cheaper) than cure.  Inevitably, however, windows and doors may require replacement and this can be undertaken throughout the year as, contrary to popular belief, we find that as many installation days are lost during the summer months due to poor weather conditions as in the winter months.  Replacing rotten timber windows could offer the opportunity to upgrade thermal efficiency, functionality and security.  For further information and a quotation call us on 01273 814870 or for further information refer to our guide Replacement Windows.
