  4. Modern Methods

Modern Methods used to maximise timber yield and lower impact on natural ecosystems.

Modern Method of Door Construction; almost all ‘off the shelf’ doors are now constructed employing new technology in timber product design & creation.

High specification adhesives & laminated core construction gives rise to a new era in production technology, bringing quality controlled production of Hardwood and Oak veneered doors into the modern age.

Protecting the environment and ecosystems

While preserving the ecological values of our delicate resources, modern methods provide us with affordable, cost effective, quality products that would otherwise be extremely expensive and unfriendly to our forests.

This evolving technology now makes it possible for the average house owner to afford high-class doors such as White Oak or Hardwood at a minimal price.

All this while maintaining low cost and effective forest management, yet still providing those in the forestry industry with employment.

We believe that any ethical company would now have moved to using engineered timber in their manufacture as it maximises timber yield from the available resources and reduces the impact on natural ecosystems.

What does it mean to you?

Engineering of the core provides extra stability and cost effective products with minimum waste.

Quality over-veneering provides forest friendly, high-class products, at affordable prices, maintaining ecological tree-cutting policies, yet still providing employment. Our Company has an eye for green issues.

Moisture Resistance

We have worked closely with component manufacturers and factories to develop a brand new construction method for exterior doors. By utilising a brand new type of substrate, we have been able to improve the stability and durability of our range of external doors, while at the same time being able to offer price reductions.
