Description
The Easyboard cement board 1200 x 800 is the smaller sheet of Euroform's Easyboard, the same mesh-faced fibre cement board as the full sheet in a smaller, lighter size. It sits with the full sheet and a board screw in Renders World's rendering cement boards.
The Cement Board 1200 x 800 Sheet
The smaller sheet keeps the board and changes the handling. Three points decide an order:
- Coverage: 1.2 m × 0.8 m = 0.96 m² of wall per sheet, before cuts.
- Weight: 13.2 kg per sheet ex-production, within 10 % either way.
- Pallet: Euroform packs this size 60 sheets to a pallet.
Euroform's parameter table for the 1200 x 800 format:
| Parameter | Value | Tolerance |
|---|---|---|
| Reaction to fire (BS EN 13501-1) | A1, non-combustible | – |
| Durability and strength (BS EN 12467) | Category B, Class 1 | – |
| Thickness | 12.5 mm | ± 10 % |
| Width | 1200 mm | ± 0.3 % |
| Length | 800 mm | ± 5 mm |
| Straightness of edges | ≤ 0.1 % | – |
| Squareness of edges | ≤ 4 mm/m | – |
| Dimensional stability, 30 % to 80 % RH at 20 °C | < 0.1 % | – |
| Average wet bending strength | ≥ 4 MPa | – |
| Apparent density | 900 kg/m³ | minimum |
| Saturated density | 1225 kg/m³ | ± 10 % |
| Thermal conductivity | 0.22 W/mK | – |
| Moisture content | 10 % | ± 2.5 |
| Weight per sheet, ex-production | 13.2 kg | ± 10 % |
Every row except length and weight matches the full sheet: the size changes, the board does not. It is conformity assessed to BS EN 12467:2012+A2:2018 for fibre cement flat sheets. A1 belongs to the board on its own; the class of a finished wall belongs to the whole build-up and is confirmed for the project under current Approved Document B guidance.
The 1200 x 800 Sheet or the Full Sheet
- 1200 x 800: this cement board 1200 x 800 sheet, 0.96 m² at 13.2 kg, under the 25 kg small-parcel limit.
- 2400 x 1200: the full 2400 x 1200 sheet, 2.88 m² at 39.6 kg.
Euroform's minimum board width is 600 mm, and both sizes are wider than that in either direction, so the smaller sheet can go up whole or be cut down to 600 mm.
What Euroform Makes the Board For
Euroform lists two uses for Easyboard:
- SFS sheathing: the use its data sheet is written around.
- Tile backing: the second use on its product page.
As a sheathing board the cement board goes behind a breather membrane and is not relied on to keep moisture out. Euroform states the board has been tested in built systems by customers and system suppliers, renders among them, and publishes no render build-up of its own, so the layers over the board come from the render system's specification. Settle them before ordering.
Fixing and Cutting the Sheet
- Fixings: self-drilling screws, the first one from a corner 40 mm in from the edge in both directions.
- Joints: at least 3 mm at every joint, boards in brick bond, no four-way joints.
- Orientation: portrait or landscape.
Once installed, the board may stay uncovered for up to 12 months before a breather membrane or similar goes over it. Below and within 150 mm of DPC level a compatible waterproofing membrane goes on, with EPDM around other places water can get in, such as window openings. The joints are covered with Euroform's own joint tape or sealant, which Renders World does not stock, so source it with the boards. The board is scored and snapped with a utility knife: score the face against a straight edge, open the cut with pressure, then run the knife back along the line through the mesh on the back. The 38 mm fixings sold with the boards are made by STS for its own 12 mm board, and STS states they suit other fibre cement sheet too. The frame-to-render sequence is set out in the guide to fixing and rendering over cement board.
Storage and Handling
- Delivery: boards arrive dry, the pallet protected from the weather under plastic sheeting or similar.
- Storage: flat, dry pallets raised on skids or battens off the ground, under cover or indoors for long stays on site.
- Carrying: by hand in a vertical position.
Ordering, Delivery and Returns
Renders World processes orders the same day when the stock is there. Put the screws in the same basket as the boards.
- Delivery: quoted by the team after the order, always kerbside. Small parcels up to 25 kg go next day; pallets up to 1200 kg go next day, or in two business days on the economy option.
- Collection: from the counter at Unit 9A, Central Trading Estate, Southampton SO14 5JP, Monday to Friday 7am to 5pm and Saturday 7am to 12pm.
- Returns: goods bought directly from Renders World can go back within 14 days in their original condition; special orders and promotion purchases are excluded.
FAQ
Is it a different board from the full sheet?
No. Euroform's table gives the same values for both sizes apart from length and weight.
How many sheets does a wall take?
One cement board 1200 x 800 covers 0.96 m². Divide the wall area by 0.96 and round up, then add the cuts around openings, keeping every cut piece at least 600 mm wide.
Can render go straight onto Easyboard?
Euroform gives no render build-up for the board and describes it as sheathing behind a breather membrane. Take the build-up from the render system's specification.
How long can it stay uncovered?
Up to 12 months once installed, before a breather membrane or similar goes over it.
Which documents come with the board?
Euroform issues a BDA Agrément certificate (BAW-22-260-P-A-UK), CE and UKCA Declarations of Performance and product safety information on request.
