Treated Tanalised Timber & Un-Treated Timber
About Our Treated Tanalised Timber & Un-Treated Timber
Our treated tanalised timber and untreated timber range provides structural reliability, consistency of section and suitability for real site conditions. From carcassing and framing through to general construction and joinery preparation, this timber forms the backbone of countless builds across Edinburgh and Glasgow. We stock regularised timber that meets the demands of professional trades and experienced DIYers, with clear grading and predictable performance on site.
Choosing between treated and untreated timber is not simply a preference; it is a technical decision based on exposure, environment and intended use. Both have a defined role within construction, and using the correct option helps avoid premature failure, movement or unnecessary remedial work later on.
Treated and Untreated Timber Range
Within this category, we supply a comprehensive selection of regularised carcassing sizes and sawn sections suitable for structural and non-structural applications. These products are available across common widths and depths to suit floor joists, stud walls, roofing work and external frameworks.
Treated Timber
Treated timber, including tanalised and pressure treated timber, is designed for use where moisture, ground contact or external exposure is expected. The treatment process protects the timber against rot and fungal decay, making it suitable for applications such as external framing, decking substructures, fencing frameworks and roofing components. Pressure treated timber is commonly specified for long-term durability and reduced maintenance requirements.
Regularised treated sections provide consistent sizing, helping speed up installation and maintain accuracy across larger builds. When used correctly, treated timber delivers dependable structural performance in environments where untreated timber would deteriorate over time.
Untreated Timber
Untreated timber is usually used for internal applications where the material is kept dry and protected. It is a popular choice for internal stud walls, floor joists, ceiling frameworks and general carcassing where treatment is unnecessary. Untreated timber is easier to machine, cut and finish, which makes it a practical choice in both joinery preparation and internal construction.
Using untreated timber in the correct environment avoids over-specification while still delivering strength and stability. It also allows for easier application of paints, sealants or specialist finishes where required.
