If you’ve ever had to repair a pella door frame after a structural failure, you know that this type of repair can be challenging.
The pella frame can be damaged, cracked or warped when the wood is exposed to high temperatures.
In a bid to overcome this challenge, a group of architects and structural engineers from the University of Cambridge and the Royal Institute of British Architects (RBI) has developed a process for repairing pella doors, which involves using epoxy to build a new wood frame.
The researchers are hoping that this new tool will help them to reduce the time and expense of repairing pellas.
They say their epoxy can be applied to any type of wood, including the most common types used in the construction industry.
They’re aiming to develop a new type of epoxy that can be used to repair the pella frames of all types of wood in order to ensure that the structural integrity of the building remains intact.
The research, conducted by the Centre for Building Science at the University and the University’s Centre for Materials Engineering, was published in the Journal of Building Science.
They believe that their method can be scaled up to other types of pellables and that it will be an ideal solution for the repair of pella wooden doors, as well as other types.
“Epoxy is an excellent material to use for pella-based doors as it is resistant to moisture, and can be readily bonded to a variety of materials,” says co-author, Professor Andrew Jones, from the Centre.
“It is a cheap and easy material, and therefore can be quickly applied to a wide range of pelly-type doors.”
This type of method could also be useful for other types for which epoxy is often not available.
“We believe that using epoxies to repair pellable materials will be particularly helpful for structural repair where the structural components are prone to stress and damage, such as pellades,” says Professor Jones.
“The epoxy has the added benefit of being lightweight, easily repairable, and inexpensive to manufacture.”
It is also extremely durable, and the wood itself can be re-attached after it has been repaired.
