Shiplap Cladding

Our Shiplap Cladding boards are made by FloPlast and carry a ten-year colour and performance guarantee and a reaction to fire classification of D-s3, d2/(AHM) (please read more below on fire safety for our Shiplap Cladding).

Each 5m x 150mm board covers an area of 0.75 square metres. A full range of trims is available to complement this range which is available in White, Black Ash, Anthracite Grey, Golden Oak and Rosewood. 

Shiplap Cladding is named due to the fact that this style of cladding was originally used as a ship siding. Nowadays the cladding can be found at many contemporary homes across the country. A main feature is the way the boards overlap each other and this style is often used to cover large areas but can be used in any external application. The product features secret fixings, where the nails used to fix one board are covered by the overlap of the next board. 


Our Shiplap comes in a range of colour finishes including: 

Board sizes are 150mm x 5m boards and either come individually or in a pack of 5 – one of these shiplap boards will cover 0.75 of a square metre.


Our PVC Cladding ranges come with a 10 year guarantee covering product performance and significant discolouration. To view Floplast's full Cladding performance guarantee document, click here.

Is PVC Shiplap Cladding Safe?

Our FloPlast cladding boards carry a reaction to fire classification of D-s3, d2/(AHM). This means that the system is not classified as non-combustible and may be used on buildings with no storey 18m or more above the ground and 1m or more from a boundary. With minor exceptions, the system should be included in calculations of unprotected area.

Although the spread-of-flame across the surface of PVC is limited, the material does tend to char and may fall away when exposed to fire. Due consideration should always be given to any combustible materials behind the cladding, which may become exposed in the event of fire. Where necessary, cavity barriers should be incorporated behind the cladding, as required under the relevant national Building Regulations.


Our Shiplap Cladding system has been assessed and given an A+ rating which allows the specifier or housebuilder to claim the code for sustainable homes maximum of three points when using PVC cladding on an external wall system.


Our ranges come in standard lengths of 5 metres and are relatively straight forward to install

If the installation is over walls which are not weather tight themselves or which are in exposed locations it is recommended that a suitable backing membrane be used to ensure the water tightness of the application.  

When it comes to installation it is important that the correct trims are used in the correct places - you should always start the installation with a starter trim, in which the first board is fixed. You can then fix that board on to your batten using a 30mm stainless steel cladding nail - the next board can cover the joint and the edges of the installation can be covered by using a universal channel.

If you are going around a corner, we have a corner trim which has openings to accept the cladding at 90 degrees to each other. Joint trims and butt joints can be used to allow for expansion between the boards either in a straight-line or staggered style.

Two-part trims can be used for the top edge and finishing under a soffit or window and drip trims can be used under a window.

There are detailed installation instructions and helpful videos available in our Guides and Tips Section.
