Responsible sourcing

Unlike many other timber window companies Bygone Collection Wooden Sash Windows are manufactured from 100% FSC (Forestry Stewardship Council) ‘Chain of Custody’ European Redwood giving the consumer peace of mind with regards to sustainability.

From the forest to the manufacturing, distribution and sales channel, to the final end-user, FSC Chain of Custody ensures that the softwood timber used to manufacture Bygone Collection sash windows originates from well-managed forests that are FSC approved.

What does FSC mean?

Trying to do the right thing and buying responsibly produced products can be confusing. The FSC label makes it easy to make the right choice when buying timber and paper products as well as other forest products. Here is why choosing FSC makes a difference:

Only FSC

prohibits conversion of natural forests or other habitat around the world
prohibits the use of highly hazardous pesticides around the world
prohibits the cultivation of genetically modified trees (GMOs)
respects the right of indigenous peoples around the world
controls each certified operation at least once a year – and if they are found not to comply, the certificate is withdrawn

Energy Saving Processes

The environmental impact of Bygone Collection’s wood waste has been reduced by investing in a wood burning boiler system with help from the Carbon Trust.

Instead of using landfill for wood waste, the solution identified was to dispose of it by transforming it into a fuel. This solution also had the advantage of reducing the overall energy costs of manufacturing process.

How does it work?

Wood waste is chipped and stored in a silo then burnt according to the energy needs of the business via a highly efficient wood waste burner/boiler. Heat is both distributed and recovered throughout the 70,000 sq ft facility. For instance, heat is used for the drying processes on the paint and preservation lines.

As far as the planet is concerned, wood burning is considered to be carbon-neutral. This is why a high proportion of wood burning systems are funded by the Carbon Trust. It is worth noting that wood contains no Sulphur or Methane, unlike conventional fuels.

Preservatives

Bygone Collection sash windows are treated with Boron anti fungal preservative. All plants depend on trace amounts of Boron to thrive, and trees need it to grow.

How does Boron preservation work?

Borates (salts of Boron) work to control insects and fungi that attack wood by inhibiting their metabolism causing them to starve and eventually die. Borate preservation delivers significant environmental advantages including:

Significant reduction of VOCs - linked to the increased production of low level Ozone causing conditions such as asthma
Effective preservative absorption and retention - Firstly the flow coating process allow Borates to penetrate the wood via the woods' moisture content. A very low level of moisture content is required to achieve effective penetration; Secondly, if moisture levels increase in service, the Borates migrate deeply where-ever there is risk of decay
Boron based preservative run-off in the flow coating process is recyclable
Boron is not classified as an environmental hazard as it is naturally occurring and does not bio-accumulate
Boron has low acute mammalian toxicity (similar to table salt)
Low to zero emissions to air, land or water - Borates do not evaporate (unlike VOC based traditional preservatives) delivering high levels of protection throughout the life of the product

Above all else, Borates have a significant track record in protecting timber for very long periods of time, and have been used successfully for over 50 years as a method of timber preservation against insect and fungal attack.
