However, it can be challenging to install and fix properly. In this article, we aim to address all the most common questions we get asked about the installation and fixing of timber cladding.
Should you nail or screw timber cladding? Do you use nails for tongue and groove?
- Nails are most commonly used to fasten timber cladding. However, you will want to opt for screws in areas with high winds or where there is likely to be significant movement. Nails are generally more cost-effective and easier to install, while screws offer more stability and durability. Screws always have a better grip than nails due to their thread, no matter what material they are going into. FIND OUR SCREWS HERE
- Stainless steel or galvanized nails are recommended for fixing timber cladding. The nails should be corrosion-resistant and long enough to penetrate the substrate and the batten- the same is true of screws.
- To nail tongue and groove cladding, first, drill pilot holes through the tongue of each board. Then, drive the nails through the pilot holes at a slight angle to avoid splitting the wood. Be sure to space the nails evenly and to countersink them slightly to allow for filling and sanding later.
How do you fix timber cladding to a wall?
- The cladding should be attached to battens or a substrate, and the fasteners should be driven through the thickest part of the board at a slight angle to avoid splitting the wood. Fasteners can be driven below the surface and filled with a suitable wood filler if required for the finish.
What goes under/behind timber cladding?
- Timber cladding should be fixed to a suitable substrate, such as sheathing, plywood, or OSB CLICK HERE FOR OUR SHEETS. The substrate should be dry, level, and free of defects that could affect the cladding’s integrity. In a professional context, a vapour-permeable membrane or building paper should also be installed between the substrate and the cladding to allow moisture to escape.
Do you need to glue tongue and groove cladding?
- Gluing tongue and groove cladding is not necessary, but it will provide a degree of additional stability and prevent movement between the boards. Glue should only be used in conjunction with other mechanical fasteners and should not be relied upon as the sole method of fixing! WE HAVE A WIDE RANGE OF GLUES AND ADHESIVES
Do you need battens for cladding?
- Battens are not always necessary for cladding, but they are often used to provide a level and secure surface for the cladding to be fixed to. Battens can also help to create an air gap between the cladding and the substrate, which can improve ventilation and prevent moisture buildup.
How far apart should battens be for cladding? /How far apart should the cladding stud be?
- The spacing of battens for cladding will depend on the thickness and profile of the cladding being used. Generally, battens should be spaced between 300mm and 600mm apart, with closer spacing for thinner or more flexible cladding.
Do you start cladding from top or bottom?
- It is recommended to start cladding from the bottom and work your way up. This will ensure that any excess water will be able to drain away and prevent water from being trapped behind the cladding.
What is the life expectancy of timber cladding?
- The life expectancy of timber cladding varies greatly due to the type of wood used, the quality of installation, the level of maintenance, and the climate of the area. Generally, timber cladding can last anywhere from 20 to 60 years with proper care.
Why does cladding need an air gap?
- Cladding needs an air gap to allow for proper ventilation and moisture management. The gap allows air to circulate behind the cladding, which helps to prevent moisture build-up and reduce the risk of mould growth. It also provides insulation, which can improve energy efficiency.
Will cladding stop damp?
- Cladding alone may not necessarily stop damp, but it can help to prevent it from occurring. Properly installed and ventilated cladding can help to manage moisture and prevent water from penetrating the walls. However, if there are underlying issues such as faulty damp proofing or high groundwater levels, additional measures may be necessary.
What is the minimum cavity for timber cladding?
- The minimum cavity for timber cladding is typically around 21mm, although this can vary depending on the type of cladding and the specific installation. A larger cavity may be needed for thicker or more moisture-sensitive cladding materials.
Does wood cladding need an air gap?
- Yes, wood cladding generally needs an air gap to allow for proper ventilation and moisture management. The specific requirements for the air gap may vary depending on the type of wood and the installation details.
How do you fasten tongue and groove to a wall?
- To fasten tongue and groove cladding to a wall, first, install furring strips or battens to the wall. Then, align the first board with the top of the wall and nail it in place, making sure to leave room for expansion and contraction. Continue adding boards, making sure to interlock the tongues and grooves securely. Finally, trim the last board to fit and nail it in place.
What does “Profile” mean when talking about cladding?
- Profile refers to the style of cladding- the shape the front has been machined into. Loglap is shaped like the front of a log with a curve to it. Shiplap has a scallop in the top to better allow water to run off it. Matching is called such due to its two chamfered edges, so once its fitted it has a matching v-groove where the boards meet.
