Yes, in fact OSB3 15mm has the same strength properties as 18mm P5 chipboard flooring. In addition, 18mm OSB3 can be a substitute for 22mm P5.

Absolutely – OSB flooring is used successfully throughout Europe. If using a battened floating floor, you must ensure that battens are used for the substructure and are appropriately spaced at 400mm centres for 15mm and up to 600mm for 18mm.

All floating floors will need to use a DPM (damp proof membrane).

SterlingOSB does everything that softwood plywood does and has many additional benefits:

  • OSB is more environmentally friendly
  • OSB generally costs slightly less
  • OSB is homegrown and is always available
  • OSB performs consistently well - plywood has variable performance
  • OSB has no core gaps, voids or weak spots

OSB stands for 'Oriented Strand Board' - in layman's terms this means strands of timber that are laid in cross directional layers and mechanically pressed to form a structurally engineered board. Oriented Strand Board (OSB) is an engineered wood-based panel designed for construction and other industrial use. SterlingOSB or ‘Sterling Board’ as it is often called is one of Europe’s most widely used and trusted structural panels.

Yes! Our OSB3 board is available T&G, ideal for many jobs such as roofing, timber frame and flooring.

OSB3 is moisture resistant, suitable for use in humid conditions. For use outdoors where the OSB will be exposed long-term, a protective varnish or coating should be used to protect the panel. 

Our OSB3 is BBA certified, OSB3 is certified for load bearing in humid conditions. Manufactured to EN300 and EN 13986.

SterlingOSB can do the same jobs softwood plywood can - including roofing, timber framing, hoarding, boarding up and sheds. OSB has the benefit of having no weak spots and a high board strength thanks to the 50 layers and cross-oriented strands that make up the board.

Yes, OSB can be painted using oil-based paints. 

OSB should be laid with the black print side facing downwards. 

CaberBoard FAQs

All FAQs relating to CaberBoard. Can't find the answer you're looking for? Get in touch.

Yes. When using our Joint & Joist glue, this practice reduces the chance of squeaking associated with joist shrinkage. Gluing the panel allows the board to move with the joist.

Yes, our CaberDek and CaberShieldPlus flooring panels are both BBA approved when installed using out CaberFix adhesives and/or tape, and as per instructions. 

When laid in accordance with our fixing instructions CaberDek and CaberShieldPlus provide a safe working platform during construction prior to roof installment. This period can be up to 42 days.

We recommend that both panels are laid, fixed and joints sealed in dry conditions. If excessive wetting occurs, ensure that any 'ponding' is cleared. Also ensure all board joints and perimeters are taped using CaberFix tape or X-treme tape (for CaberDek) or CaberFix D4 glue (for CaberShieldPlus). 

They are both very strong and design for fixing chipboard flooring. Joint & Joist is a mastic glue whereas D4 is a foaming glue.

Joint & Joist is slightly flexible, ensuring a silent floor, with good cohesion strength. This required a skeleton gun and can require additional products (tape) to seal the flooring.

CaberFix D4 forms a brittle bond line and is less flexible. However, it omits the need for tape as the glue can also be used to seal the edges of the boards. The bottle is hand-held and provides a one-bottle solution for all sealing and fixing - no need for tape!

18mm panels - 80 boards

22mm panels - 66 boards

Taping joints provides superior moisture protection compared to glue alone. Taping the perimeter ensures the BBA guarantee is valid on the floor and provides protection from moisture and construction mess. 

We have a CaberFix Pro fixing kit available designed to comprehensively cover 50m² area. This equates to approximately 35 boards (or roughly half a pack).

6 rolls of tape would be needed to secure and entire pack of boards. 

Recommended expansion gap is 2mm per metre run. The usual practice is to leave this gap at the perimeter so it can be covered by skirting boards.

A 2mm gap must also be provided at any abutments, i.e. internal partitions, door thresholds or pillars.

The immediate effect would be a more "springy" floor. It is not expected that failure would occur in domestic circumstances, however it must be recognised that NHBC guarantees may not apply and hence the client may wish to put the floor in order. This would be our recommendation in this instance.

Our particleboard flooring panels should be laid text-side up.

Yes! The edges should always be supported.

No – all short ends must be supported by a joist.

It is common in new build situations for boards to increase in moisture content. Fortunately, this behaviour is predictable and as a guide an increase in moisture of 3% increases length and width by 0.1%. This is normal and given building operations continue 12 months per year - levels do tend to be higher in October to March in the UK compared to the summer months. Typical levels of moisture content in flooring panels in an unheated building tend to be up to 15%. Intermittent heating will typically reduce this level to 9% to 12% and a typical further reduction would be 7% to 9% in a continuously centrally heated space.

For water exposure during construction, wipe dry as soon as possible. If water is a future concern, consider one of our waterproof chipboard flooring solutions - CaberDek or CaberShieldPlus.

The durability of CaberFloor P5 Moisture Resistant is excellent. This is due to specially developed melamine fortified resins being used during the construction process.

On exposure to intermittent rain and dampness the product retains a high percentage of its original strength. It is recommended that CaberFloor is installed in dry conditions. It is important to understand that CaberFloor P5 is not ‘waterproof’ and should never be used as such.

For all first floor and above applications, 22mm CaberBoard flooring should be used (CaberFloor P5, CaberDek or CaberShieldPlus). This satisfies building control and NHBC requirements.

In connection with joist centres, the maximum spans are 450mm for 18mm and 600mm for 22mm. These are for domestic applications only.

It is more usual to use 400 or 600mm joist spacing as they "fit" the most commonly used board lengths of 2400mm.

For a silent floor we recommend use of our Joint & Joist adhesive to glue boards to joists (5 times stronger than nails). Alternative, our one-bottle solution CaberFix D4 can be used for all panel fixing and sealing.

However panels can also be screwed or nailed to joists, battens or existing timber floors. Panels should be nailed at 200 - 300mm centres along the edges and 300mm elsewhere along the joists. Fixing should be at least 9mm from the edge of the panel and nails should be 10 gauge.

In practice this equates to 3 fixings on short ends and 2 fixings at intermediate joist positions. When gluing boards with Joint & Joist, only 5 fixings per board are required, one at each joist position.

Yes - CaberFloor P5, CaberDek and CaberShieldPlus all meet the requirements of latest E1 definition when tested according to EN120.

Our board are designed to be laid the right way up. The floor will not be a strong if upside-down, even if correct adhesives have been used.

Yes – Caberwood MDF all meet the requirements of latest E1 definition when tested according to EN120.

No - this is a common myth, all wood related products create dust when cut or machined. We advise the use of appropriate PPE and ventilation when machining, cutting, drilling, sawing any timber product including MDF. For further information on working with MDF and wood panels, download our MSDS sheet.

Most types of screws can be used. Best results are obtained with parallel thread screws.

Yes, you can paint onto MDF using oil-based paints. 

CaberWood MDF is available in five main grades – Trade (Light), Pro (Standard), Trade Moisture Resistant, Pro Moisture Resistant and Industrial. Colour is a means of identification between the MR and non-MR grades and does not correlate to the board performance.

Trade, Pro and Industrial Grades are the traditional 'sandy' colour, whereas Pro Moisture Resistant and Trade Moisture Resistant are distinguished by a green identification dye.

Norbord do not currently product this. We do, however, make a fire-resistant OSB - SterlingOSB Fire Solutions.

Norbord do not currently produce this thickness of MDF. We currently go down to 6mm.
