Description
This 10mm EPS is a grey polystyrene board, 1000 × 500 mm, and the thinnest of eleven thicknesses in the Renders World graphite board range. One board is 0.5 m² of face and 10 mm deep, so it is a board for places where depth runs out, not for insulating a whole wall.
10mm EPS: What You Get
- Size: 1000 mm long, 500 mm wide and 10 mm thick, which is 0.5 m² per board.
- Material: grey expanded polystyrene, listed in the shop as POLYSTYRENE EPS GRAFIT 10mm.
- Photos: the first image is the range photo used on several thicknesses and shows the grey board, not this thickness; the second shows a single thin grey board lying flat, with no marking on it.
The Data Sheet Starts at 20 mm
The range's data sheet makes the façade boards from 20 mm thick and then in steps of 10 mm. 10mm EPS is thinner than anything on that sheet, so these are not declared for it:
- thermal conductivity and reaction to fire;
- bending and tensile strength;
- tolerances and pack size.
Where a specification needs declared figures at a reveal or a junction, the 20 mm board is the thinnest one the data sheet covers. Its page carries the declared values and the fixing method.
10 mm, 20 mm or 30 mm
- 10 mm: no declared values; 10mm EPS is for where only a strip fits.
- 20 mm: the thinnest thickness with a data sheet behind it.
- 30 mm: the next step up, on the same data sheet.
The thickness a wall needs comes from the calculation of the whole build-up, not from the board; the U-value and insulation thickness guide shows how that is done.
How Many Boards to Order
Every board covers half a square metre, so a square metre takes a pair of boards. Worked through:
- A reveal lining of 4 m² takes 4 ÷ 0.5 = 8 boards.
- Strips are cut from whole boards, so count the boards the strips come from, not the strips.
Fitting
- Adhesive: bonding mortars for insulation boards are in the adhesives and basecoats for insulation boards range; use the chosen adhesive to its own data sheet, since none is declared for 10mm EPS.
- Layers: where the board sits within a rendered wall is set out in the EWI build-up and layers guide.
Ordering, Delivery and Returns
Renders World processes orders the same day when the stock is there.
- Delivery: quoted by the team after the order; parcels up to 25 kg go next day, pallets next day or in two business days on the economy option, always kerbside.
- 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
What size is one board?
1000 × 500 × 10 mm, which is 0.5 m² of face. Two boards cover one square metre.
What is its thermal conductivity?
None is declared for 10 mm: the data sheet for the range starts at 20 mm. For a declared value, use the 20 mm board or thicker.
Can I insulate a whole wall with it?
A whole wall is insulated to a thickness set by calculation, and the thicker boards in the range are the ones the data sheet covers. This board is for places where only 10 mm fits.
