Calculating Materials
To figure out the amount of materials you will need, you can either use our online cladding calculator or contact us for a same-day quotation. Equally if you have someone on hand doing the install and working out your quantities, they are more than welcome to call to get a second opinion.
Below we outline a popular choice of materials and design for a garden office but for more detailed information, visit our detailed cladding installation guide.
Before you Start
If installing yourself, ensure that you have taken thorough measurements. Some key points to have in mind whilst installing are:
- A minimum of 38mm is required for a ventilation cavity
- Battens should run perpendicular to the boards and secured at 600mm intervals
- There needs to be extra wall battening around windows and doors
For more information, see our cladding installation guide.
Installing the Cladding
The first board should run 20mm above the ground. We recommend to pre-drill pilot holes 2mm wider than the screw before screwing through the baton.
Place the bottom cladding boards in position and fix them to the batten using A2/A4 Pan Head 8 gauge 38mm screw (max. 2mm head thickness).
Place the next cladding board on top, check the level, predrill the screw holes, then fix the board to the battens and repeat the process until you reach the top of the building.
Note: Boards may need to be cut in order to fit around opening areas like windows and doors.
To cleanly finish your space, round off vertical corners and openings with 90 degree corner trims and/or edge boards (dependent on your preference).
To cover the edges of cladding boards around opening areas, measure the required amount and mitre down to a 45 degrees. Place over the corner trim to cover, pre-drill and countersink through the trim.
Note: coloured screws are available if you are concerned about the visibility of screws.
Hyperion corner trims can be combined with fascia to cover deeper window and door-frames.
