CEDRAL® LAP BOARDS

Cedral® Lap system is built of multilayer fibre cement planks in order to provide traditional overlap appearance and weather protection all year round. Lap boards connect together similarly but each plank has an added overlap at the bottom when laid horizontally giving a repeating step. The notch on one side of the plank will be on the upper edge, while the other side of the plank is notched on the lower edge. During installation, these notches fit together like little steps, so the shiplap planks very slightly overlap, in what is called a Lap joint. 
For installations that need to withstand harsh elements and heavy rainfall, Lap is simply the preferable option. Cedral Lap cladding is chosen in a wood textured finish. Lap is an easier option than Click for DIYers because of how the panels connect and how they are attached to the wall. Fitted, never requires re-painting. In fact, Lap is the better choice for a very rainy climate, as its overlapping planks shed water quite well. It is a practically maintenance-free cladding system. Moreover, the product offers up to 3 times more dimensional stability than wood. With the use of fiber cement siding you will not encounter loud noise that occurs during strong gusts of wind, rain or hail.

CEDRAL® LAP DETAIL

Cedral® lap sidings are weatherboards made of fibre cement with an excellent fire-resistance rating of A2-s1, d0. This means they are non-flammable, so in the event of a fire they will barely generate any smoke and will not spread fire. The Cedral® boards are available in all 21 standard painted finishes and also the 2 wood stain finishes. Lap boards are manufactured in 3600mm lengths by 190mm width and 10mm thickness. Each lap board requires a 30mm lap on installation giving a cover width of 160mm per board. Each board will cover 0.57m2, alternatively please allow 1.74 board per m2. Vertical battens to be spaced a maximum of 600mm apart (reduce this in high wind-load areas). Unlike wood or PVC sidings, these boards do not swell or contract due to temperature changes or humidity. 

According to our current Cedral price list average Cedral Lap board cost is £43,29 (ex VAT) per metre squared. The manufacturer provides a warranty not only for the products, but also for their colouring for a period of 10 years. The manufacturer claims that the product retains all the declared characteristics for 50 years.

HOW IS CEDRAL® LAP BOARD MANUFACTURED?

Cedral® Lap boards are manufactured using laboratory methods simulating the ”Hatschek Process”. The Hatschek process consists of the formation of thin “paper-like films that are placed one on the other until the desired sheet thickness is reached”. Generally speaking cladding boards are made of:

Portland Cement – binds all the ingredients.
Cellulose fibres – sourced from sustainable reserves, act as filter fibres.​
Synthetic fibres – used as reinforcing fibres.​
Sand – used for its resilience and weather performance.
​Water – brings it all together and activates the hardening process of the cement. ​

CEDRAL® LAP VS CLICK

If you check out the edges of planks for each panelling system, you’ll spot the difference between them right away. Cedral® Lap cladding is designed to look like the overlapping boards used throughout history to build the hull of ships. However, if a more modern design element is priority, Click board might be your best choice. While Click board prevents water seeping through joins and into the structure, Lap is even more waterproof. The overhanging 30mm lip prevents backflow of water through the boards. For use in areas with particularly high rainfall, this gives it a clear edge in weatherproofing. If you’re drawn to the appearance of one profile over the other, that should really be the deciding factor. Both systems represent a beautiful and secure cladding profile choice. Before discussing the differences between the two styles, it is helpful to understand the way they fit together. Lap boards connect together similarly but each plank has an added overlap at the bottom when laid horizontally giving a repeating step. 
The notch on one side of the plank will be on the upper edge, while the other side of the plank is notched on the lower edge. During installation, these notches fit together like little steps, so the shiplap planks very slightly overlap, in what is called a Lap joint. 
For installations that need to withstand harsh elements and heavy rainfall, Lap is the preferable option. Cedral® Lap cladding is chosen in a wood textured finish. Unlike Cedral Lap, each plank of Cedral Click has a groove on one edge and a corresponding thin projecting ridge on the other (the tongue). When two planks are pushed together, the tongue ‘click’ into the groove along their length to give a strong join with no need for glues- hence the name. The individual planks fit together almost seamlessly, making them perfect for plain wooden cladding on modern wall panelling.
It’s a little easier to install Lap planks than Click. It is because you needn’t fit the boards together. Instead, you simply match the notches on neighbouring boards and then pound a nail straight through the overlap. Installing Click requires more precise screwing, as you’ll need to screw invisible clips for secure results.
Both connection systems are made of the same multilayer fibre structure, however their thicknesses vary. Cedral® Lap starter creates an overall thickness of 21mm leaving a 10mm gap on the bottom. On the other hand, the Cedral® Click starter profile creates only 13mm (12mm board+1mm aluminium starter profile). That gives us 8mm of difference. While Click board prevents water seeping through joins and into the structure, Lap is even more waterproof. The overhanging 30mm lip prevents backflow of water through the boards. For use in areas with particularly high rainfall, this gives it a clear edge in weatherproofing.

CEDRAL® WOOD FIBRE CEMENT WEATHERBOARD CLADDING COST

If the choice is mainly an aesthetic one based on looks, Lap system may be a more cost effective option. Why? According to our current Cedral price list average costs are £43,29 (ex VAT) per metre squared for Cedral® Lap and £59,12 (ex VAT) per metre squared for Cedral® Click (excluding trims and accessories). For those on a particularly tight budget, simple Lap cladding may be worth considering. Depending on the system, average Cedral cladding may vary from £4000 to £7700. This includes material but no labour costs. Cedral® is distributed through stockists. Any pricing should be checked with the nearest Cedral® stockists.
