Treated Roofing Timber

SR Timber’s range of treated speciality roofing timber are either manufactured at our partner sawmill in Latvia or sourced via carefully selected 3rd party production partners across Europe. Many of these timbers are smaller in section making them more difficult to produce and therefore not as widely available to source as other construction timber. SR Timber have long standing relationships with our partner mills giving us the continuity of supply our customers need and have come to expect.

Treated Carcassing

Carcassing is normally British or European Whitewood (Spruce). It will be strength graded to C16 for general structural applications in floors, walls and roofs. The higher strength class C24 is intended for longer span or greater load applications.

Other species may also be available for more specialist applications such as European Redwood (Pine), which takes preservative treatment well and so is ideally suited for structural exterior Use Class 4 applications, including deck joists and substructures.

Carcassing is mostly supplied machined, which means consistent sizes and reduced splinters for the safety of construction workers. This is also why edges are ‘eased’.

It can be supplied untreated or preservative treated, so make sure you get the Use Class treatment level right for the customer’s intended end use. Most Carcassing is only supplied treated to Use Class 2 – suitable only for applications within the building envelope.

Untreated Carcassing

As well as treated carcassing, SR Timber offer a range of untreated carcassing alternatives. Likewise, these are normally British or European Whitewood (Spruce) and will be strength graded to C16 or the higher strength class, C24.

Canadian Lumber Standard (CLS)

The most common form of timber for studding and creating internal partitions is CLS, which is supplied regularised (surfaced) with eased edges. It is usually made from kiln-dried Whitewood (Spruce) and strength graded to C16.

Cedar Shingles & Ridge

Blue Label 5X Western Red Cedar Shingles are the highest grade of shingles available. Cedar is naturally insect and rot resistant requiring no further treatment and sourced from sustainable forests in Western Canada. After weathering they will adopt a silvery grey shade.

SR Timber offer both treated and untreated options on our range of Shingles and Ridge to suit varying applications. It advised to check NFRC technical guidance notes on fixing cedar shingles and if treatment advised, this tends to be calculated on geographical location of which the product is to be fixed. Good practice is to also follow specification and fixers advice.

Preservative Treated Wood

Preservative treatment provides wood with added durability. However, it’s a mistake to assume that all pressure treated wood is the same. Whilst one piece of treated wood may look very much like any other, the level of preservative protection could be very different. That’s because national technical standards for wood preservation require that the loading and penetration of preservative, impregnated into the wood, is tailored to the desired end use.

Scaffold Boards

Scaffold Boards are produced to the highest standards and imported as a finished product to our timber terminal here in the UK. You can rest assured that all Scaffold Boards are fully compliant to BS 2482:2009. Furthermore, Scaffold Boards have achieved CATG 3rd party accreditation meaning our boards are of the highest level of quality and safety.

Oriented Strand Board (OSB)

Chipboard Flooring

Chipboard is made from a mixture of wood types such as wood chips, sawdust, shavings, etc, which are mixed with resin, compressed and dried. It is available in different forms such as three-layer, moisture-resistant and cement-bonded.

Chipboard technical classes are defined in BS EN 312 and range from P1-P7, but for merchants, the following are probably most critical:

P1: General purpose boards for use in dry conditions
P2: boards for interior fitments (including furniture) for use in dry conditions
P3: non-load-bearing boards for use in humid conditions
P5: load-bearing boards for use in humid conditions, most commonly seen as T&G Particleboard flooring
P6: heavy duty load-bearing boards for use in dry conditions, most ofter used as a specialist mezzanine floor product.
It’s important to remember that moisture-resistant does not mean ‘waterproof’.

Plywood & Sheet Materials

Plywood consists of fine sheets of wood, or veneers bonded with glue. Plywood is a versatile product that can combine attractive surface appearance with superior performance under hazardous conditions while retaining comparatively high strength-to-weight ratios. It is available in a range of wood species, including hardwood and softwood species and combinations of the two, and a range of resin types for interior, high humidity and exterior conditions. Plywood was the first type of board developed to provide panels with dimensional stability and good strength both along and across the panel.
