Key takeaways
- TimberLuxe doors use responsibly sourced engineered timber within a substantial 48mm core.
- Timber stores carbon absorbed during tree growth, helping make timber an important renewable construction material.
- The TimberLuxe moisture barrier is manufactured using recycled uPVC.
- Manufacturing waste is diverted away from landfill wherever possible, while suitable materials removed from customer’s homes are recycled.
- The 49mm engineered timber core helps improve thermal performance and reduce unwanted heat loss.
- Four seedlings are planted to offset the timber used in each TimberLuxe door, with more than 6,000 trees planted since launch.
- Professional installation is essential, as even a high-performance door can lose efficiency if it is poorly fitted.
At CR Smith, we have been manufacturing and installing windows and doors in Scotland for more than five decades. Our TimberLuxe engineered timber composite doors are designed to combine security, thermal performance and durability with more responsibly sourced materials.
For homeowners looking to reduce the environmental impact of their home improvements, the materials used within a front door, hoe it is manufactured and how efficiently it performs once installed all matter.
What makes an engineered timber composite door eco-friendly?
An engineered timber composite door can be considered more environmentally responsible when its materials are renewable or recycled, waste is minimised during production and the finished door provides strong thermal performance over a long service life.
TimberLuxe doors incorporate several of these features, including:
- Responsibly sourced engineered timber
- Recycled uPVC components
- Manufacturing processes designed to minimise landfill waste
- Recyclable materials within the wider installation process
- Strong thermal insulation
- Durable construction designed to extend product lifespan
The environmental impact of a door should therefore be assessed across its full lifecycle rather than simply by whether it is described as a composite door.
Why is engineered timber considered a sustainable material?
Timber is renewable when it coms from responsibly managed forests, and trees absorb carbon dioxide from the atmosphere as they grow.
The engineered timber used within TimberLuxe doors is sourced from forests managed according to environmental, social and economic standards.
For every traa associated with TimberLuxe production, four new seedlings are planted to suport long-term reforestation.
At the centre of each TimberLuxe door is Mestä Kerto LVL, or laminated veneer lumber. This engineered timber is designed to provide strength, durability and dimensional stability.
Accorfing to Mestä, around one tonne of carbon dioxide can be stored within one cubic metre or Kerto LVL.
This means the timber core not only contributes to the performance of the door but also stores carbon absorbed during the growth of the trees used to produce it.
Are TimberLuxe doors made using recycled materials?
TimberLuxe doors include a moisture barrier manufactured from recycled uPVC.
The moisture barrier protects the engineered timber core from moisture ingress while giving existing plastic material another useful lifecycly.
Protecting the timber core is also important for longevity, as reducing exposure to moisture helps maintain the structural integrity of the door over time.
A door that remains functional for longer may help reduce the environmental impact associated with early replacement.
Do TimberLuxe doors create manufacturing waste?
TimberLuxe manufacturing follows a zero-waste-to-landfill approach, with production waste redirected away from landfill wherever possible.
CR Smith also separated materials removed from customers’ homes during replacement installations.
Suitable mateirals including:
- uPVC
- Timber
- Metal
- Glass
are recycled through specialist third-party partners where appropriate.
Reducing waste at both manufacturing and installation stages helps limit the overall environmental impact of replacing a front door.
How does a TimberLuxe door help improve energy efficiency?
A well-insulated front door can help reduce unwanted heat loss from a property, particularly when replacing an old, draughty or poorly insulated door.
TimberLuxe doors contained a 48mm cross-laminated engineered timber core, which is around 10% thicker than the core used in many standard composite doors.
The timber core is designed to offer:
- Stronger thermal insualtion
- Resistance to heat transfer
- Structural stability
- Long-term durability
Reducing heat loss through the entrance to the home can help lower the amount of energy required to maintain a comfortable indoor temperature.
The door itself, however, is only part of the overall performance.
Does professional installation affect sustainability?
A high-performance door can still underperform is it is badly installed.
Poor sealing, gaps around the frame or inadequate insulation can allow draughts and unwanted heat loss, reducing the benefit of choosing an energy-efficient door.
CR Smith installations are completed by directly employed tradespeople trained to work to the Lorimer Fit Standard.
The installation process focuses on creating a well-fitted and insulated connection between the door, frame and surrounding structure.
As CR Smith Chief Executive Kevin Eadie explains:
“A window or door’s performance is only ever as good as its fitting.”
Good installation therefore helps ensure the thermal performance designed into the door is maintained once it becomes part of the home.
Are engineered timber composite doors better for the environment than standard composite doors?
They can be, but it depends on how each door is constructed and manufactured.
The term composite door covers a wide variety of products made from different combinations of materials. Some use polythurethane foam cores, while others use particleboard, timber or engineered timber.
An engineered timber composite door such as TimberLuxe uses timber as a significant structural material rather than relying on synthetic foam.
When comparing the environmental credentials of different composite doors, homeowners should consider:
- Where the raw materials come from
- Whether timber is responsibly sourced
- Whether recycled materials are used
- How much waste is produced during manufacture
- Whether components can be recycled
- How long the door is expected to last
- Its thermal efficiency
- How it will be installed
This gives a more complete picture than comparing products based solely on their composite-door label.
How many trees have been planted through TimberLuxe?
Four seedlings are planted to offset the timber used in the construction of each TimberLuxe engineered timber composite door.
Since the introduction of the TimberLuxe range, this programme has contributed to the planting of more than 6,000 trees.
Replanting helps support responsible forestry and the continued availability of timber as a renewable construction material.
What are the environmental benefits of choosing TimberLuxe?
Choosing TimberLuxe combines several environmental considerations within one door design.
These include:
- Responsibly sourced engineered timber
- Carbon stored within the timber itself
- Recycled uPVC within the moisture barrier
- Manufacturing waste diverted from landfill
- Recyclable materials recovered during replacement installations
- Strong thermal performance
- Durable construction designed for a long service life
Together, these measures contribute to reducing environmental impact across the production, installation and everyday use of the door.
Are TimberLuxe doors suitable for Scottish homes?
TimberLuxe doors are designed to combine thermal performance, security and durability for home across Scotland.
Their engineered timber construction provides substantial insulation while the moisture barrier helps protect the internal timber structure from moisture ingress.
For Scottish homeowners, where exposure to wind, rain and cooler temperatures can place additional demands on external doors, both product performance and installation quality are particularly important.
A properly fitted, well-insulated front door can help reduce draughts and heat loss while also providing long-term weather resistance.
FAQs
Replacing an old or poorly insulated front door with a well-insulated and professionally installed alternative can help reduce draughts and unwanted heat loss.
Engineered timber doors are made from layers of laminated timber pressed together in opposing directions. This cross-laminated construction increases strength and rigidity while helping to reduce warping and cracking, making the door more resistant to changes in temperature and weather conditions.
Engineered timber is used because it offers greater strength and stability than standard timber while retaining its natural insulating properties. Its layered construction helps reduce warping and cracking, making it a durable choice for external doors exposed to changing weather conditions.
