Traditional Scottish Timber Front Doors

The following article is based on a leaflet produced by Historic Scotland’s Technical Conservation, Research and Educational Group.

Original timber doors are an important aspect of the character and authenticity of a Scottish home. Their proportions and positions, together with the detail of mouldings and panelling are important elements in the aesthetics and significance of a building. Traditional Scottish external timber doors were made of pine or, occasionally, hardwoods, such as oak. Many were highly decorated, with imposing surrounds of columns, canopies and classically inspired pediments.

Over the past few decades many traditional timber doors have been inappropriately replaced with modern doors made from materials such as UPVC and aluminium. These products not only alter the character and appearance of a building but it is unlikely that they will last as long as a traditional timber door that has been maintained correctly. As a result, many of Scotland’s local authorities now operate a policy that discourages the installation of these type of doors in Listed buildings.

A brief history of timber doors

This following very briefly outlines the main influences on door designs over the past few centuries:

  • Industrial Revolution – Easier and cheaper transportation of raw materials led to mass production of doors and standardisation of designs.
  • Chubb Detector Lock – At the end of the eighteenth century developments in lock technology such as the invention of the first Chubb Detector Lock meant that traditional doors could be made more secure.
  • Introduction of Fanlights – During the Georgian period, many houses were built with doors that incorporated fanlights above the main entrance. Over time these designs became extremely ornate and the use of decorative glass became very common.
  • World War I and II – In times of austerity after the First World War period doors were often replaced with cheaper simpler designs, and following the Second World War – mouldings were covered over with solid wood or plywood panels.

External timber door construction.

Here at TJ Ross our traditional timber doors have real ‘kerb appeal’.  Handmade by our highly skilled craftsmen using traditional mortice and tenon joints tightened up throughout by the use of small wedges driven and glued into the tenon. Our door panels are held in place by being inserted into grooves cut in the door frame. This construction allows the timber panels to move slightly as the timber expands and contracts with climatic changes in temperature and humidity.

We encourage our customers to choose a timber design and paint finish that is as close a match or indeed a like-for-like replacement.  Failure to do this can affect the building’s aesthetic appeal and may reduce the property’s market value. Original proportions should be maintained as timber doors will always look better on traditional buildings than modern plastic ornamental alternatives.

How to maintain your timber windows

Here at TJ Ross we pride ourselves on designing and manufacturing high performance windows.  All our windows are pre-finished prior to delivery or installation.  We want our windows to last for as long as possible, so in order to do this we dry fit all the ironmongery ie fit all the locks and handles etc. to the bare frame before removing them again in order to apply a high quality preservative manufactured by the Teknos, the market leader in coatings for external joinery, in our own workshop.  The Teknos preservative coating has a high quality of elasticity which means that it works like ‘Goretex’ for wood.  The handles and locks etc. are then re-fitted along with the glazing to ensure that every part of the timber is completely sealed and water tight.

Seal the cills!

We sell windows on a supply only basis to joiners and building contractors.  The main differences here are:

  1. Your joiner will have taken all the measurements, not T J Ross
  2. Your joiner will install the windows not T J Ross

If the measurements taken are accurate, then the window and window cill will be a perfect fit.  But, if for a number of reasons it doesn’t fit – the joiner may need to cut the window cill after it has been made, exposing the timber at the end of the cill allowing water ingress into the timber.

As a result of this, all ‘supply only’ T J Ross windows are delivered with a small pot of micro porous preservative in the colour or stain applied to the window – just in case the cill needs to be cut to fit.

Provided the sealant is applied to the end that has been cut BEFORE installation takes place, then the window will remain watertight and efficient.

Good installation practice avoids future damage and ensures your windows will last and saves you money both in reduced heating bills and window costs.
