The Advantages Of Engineered Timber Over Solid Doors
What Are Engineered Doors?
Engineered doors are simply doors which have been created from engineered timber, rather than solid wood. While they share the same aesthetic qualities as solid wood doors, and have no hollow core, engineered timber doors have a host of additional benefits and advantages.
What Is Engineered Timber?
Engineered timber is simply individual pieces of high-grade timber which have been cut and bonded back together in a specific way. To understand why this is beneficial, you must first consider how solid wood is affected by natural factors.
When exposed to heat or humidity, solid wood undergoes a process of expansion and contraction, following the direction or flow of the grain. This is a constant process which over time results in permanent changes to the wood’s shape and size, or warping. This is especially true of external doors, which are subjected to varying conditions and temperatures either side. When a door scrapes across the ground, or doesn’t open like it once did, it’s almost always due to this unavoidable drawback of solid wood.
With a solid engineered core door, the finest-grade pieces of timber are cut into strips and bonded together in a way which ensures alternating grain flows. This negates the effects of heat and humidity as the door is expanding and contracting in opposite directions, effectively stopping itself from warping over time.
Why Use Engineered Timber?
- Is bonded through extreme heat and compression, resulting in an incredibly strong finished product.
- Employs cross-grained layering to negate the warping effects of heat and humidity, allowing the door to stand the test of time.
- Circulates and retains heats more efficiently, effectively reducing energy wastage and costs.
