Close Board Panel Blogs

You don't have to join The Green Party to help planet earth. You can simply use gravelboard when you are erecting your garden fence! Why? Because then your fences will last longer, and you will be saving lots of trees, as well as saving yourself heaps of money and backbreaking work in the future.

What are Gravelboards?

Gravelboards fit under a fence at ground level. They can be timber gravel boards which are used withTimber Posts or Concrete Gravelboards used with slotted concrete fence posts. These are normally 6”/150mm or 12” / 300mm high.

Whats the purpose of Gravelboards?

1. 
   Gravelboards keep expensive timber fence panels or fence pales ends off of the damp ground thus protecting from rotting. Timber gravelboards are cheap and easy to replace so can in a way be sacrificed.
2. 
   Gravelboards are essential for fencing on sloping ground. Fence panels have to be stepped which can leave a gap at ground level – a gravel board can help as one end can be buried into the ground meaning the other end will fill the gap.
3. 
   Concrete gravelboards (the type used for fence panels and with concrete fence posts), can be used to hold back soil if ground levels on each side of fence different. For example, between your garden and your neighbours garden.

Remember to allow for longer posts to accommodate – sometimes you can use lower panels so the fence does not become too tall. Like Fence Panels, gravelboard is normally fixed between posts rather than on the front face, therefore, wood blocks called cleats are normally used to aid fixing with nails.

Gravelboards can be used anywhere there is garden fencing, not forgetting, commercial sites like factories .

What is a Panel Fence

A pre-made timber panel, of differing styles and qualities, that are fixed between two posts.

Types of Panel

Panels are available in 3 different colours, a light beige (pressure treated), gold (orange/brown) and dark brown which are dipped. Check stocks for the range at your branch.

The styles can be broken down into:

Lap Panels - A waney edged board, overlapped and fixed horizontally within a batten frame, described as fully framed – meaning they have timber around the outside edge. They also have vertical battens fixed across the face and back of the panel to strengthen the laps.

Close board Panels - A feather edge board, overlapped and fixed vertically on a heavier duty batten formation. Stronger than the lap panel, but not as strong as true closeboarding.

'The above are sold in 6ft widths, starting at 3ft high in 1ft increments, up to 6ft high.'

Continental Panels - A decorative panel, with different designs of infill and tops, with a limited range of heights.

'The above are sold in 1.8m widths and varying heights, these are all in the light beige colour only, fully pressure treated.'

Posts

All panels can either be put on timber posts or concrete slotted posts; it is purely the customer’s personal choice.

On softwood timber posts the options would be: 75 x 75mm 100 x 75mm 100 x 100mm

The panels would be fitted to these via met clips, a U shape bracket, or nails/screws fixed through the side batten, pre drilling is advised. The timber posts can either be concreted into the ground or met posts could be used. If they are being concreted in, the post should go into the ground a minimum of 600mm; if met posts are being used the post will be shorter.

The concrete post has a slot that runs down the complete length of the post, which allows the panel to slot into the post. This is fine on installation, but remember that if a panel needs replacing later on, the panel has to be lifted above the posts and slotted down, e.g. a 6ft high panel would need lifting 6ft in the air to replace.

The options available for slotted posts are: Intermediates Ends Corners

The corners and ends are not handed as the slot is central to the post.

The panels are not actually fixed to the concrete so just sit in the slot; this does mean that they can move around if the panel is thinner than the slot.

Wall Fixing

If the fence is adjoining any walls then a wall plate can be used, either a 100x 47mm or a 75 x 47mm, which is bolted to the wall using suitable fixings, such as thunderbolts, hammer fixings or coach screws; then the panel fixed to this.

Post Tops

The tops of the posts can be left flat, machined or a post cap with or without a finial can be fitted. The finials are commonly acorns or balls, but others are available, these are fitted via a double threaded screw.

Sloping Ground

Remember that if the ground is sloping with the fence line, longer posts will be required to allow for the extra height caused by the panel sitting off the ground. As the panel should always sit level and should never be buried at the high side.

Gravel Boards

These are not only used for their ability to increase the height of the fence, but they are also used to prevent the panel from coming into contact with the ground; thus helping prolong the life of the panel.

They can also be used to fill the gaps beneath panels caused by steeping and inconsistencies in the ground level.

Timber Gravel Boards

Timber gravel boards are fixed to the timber post using cleats, which means it is unnecessary to use any fixings between the panels and gravel boards. Remember that if continental panels are used, then the standard 6ft gravel board is going to be too long and must be cut prior to installation.

Concrete Gravel Boards

In the instance of concrete gravel boards they can be used to retain light soil, as they are stronger and will not rot like timber; these slot into the concrete post. They are available in both 150mm and 300mm high. If these boards are used with continental panels, fillets would need to be used to increase the width of the panel.

Cutting Panels

As most gardens will not be exactly divisible by the panel width, it may be necessary to cut a panel to fit. It is easily achievable on lap and close board panels, but not so with continental panels, as the framing is jointed in the corners.

To cut a lap panel down, the battens are removed from one end of the panel and fixed into a similar position at the required width; so the cutting of horizontal battens is required. Once fitted the excess laps can be cut off.

Installing Panelled Fence Using Concrete

If concreting in, set the first post and measure out for your second hole and excavate. Once at the desired depth, fix the panel in place and fix the second post to it, checking for level and line. Once happy with the position concrete the second post in and then carry on the process until the fence is complete. Remember depending on the method of concreting used, it may be necessary to put temporary props on the fence to allow the concrete to set.

Note: If the fence is on a slope it is easier to start at the top of the slope, to ensure you get the height of the posts correct.
