ROOFMATE PS For Pitched Roofs


Roofmate PS Boards * are applied on pitched roof, without using any roof wood and together with the thermal insulation applied on the beam rafter (Covered Insulation System), all kinds of tiles and roof cover.


- The cross sections of the beam rafters and joints are calculated having taken into account the materials used on the roofs and their weight and the beam rafters are placed in intervals of 40 cm, If Roofmate PS of 4 cm thickness are to be used, 50 cm of intervals if Roofmate PS of 5 cm thickness is to be used, and 60 cm of intervals if Roofmate PS of 6 cm thickness is to be used.

- Roofmate PS boards (60 cm. X 300 cm.) are placed on the beam rafters in vertical direction to the beam rafters; and are temporarily attached with nails.

- A water-proof membrane with low vapour permeability resistance (Sd£0.16m.) is placed on top of each other from down below upwards.

- The Roofmate PS boards as well as the pressure bars are fixed onto the beam rafter with the help of head nails.

- For every line of roof tiles one tile bar is aligned in the vertical direction to the pressure bars and the roof tiles are fixed to these bars.

- For the application of Shingle water plywood, chip wood etc. Type boards are placed on the pressure bars and this shingle type cover is fixed onto these boards and the roof is thus completed. In this application there is no need for an extra water resistance membrane to be used.

- It is advisable to keep the Roofmate PS boards and the bars to be fixed at the same time and order and proceed with the work. Application workers are advised not to walk around these bars and the beam rafters.


1) Cushion,
2) Beam rafter,
3) Roofmate* PS thermal resistance board
4) Water proofing membrane
5) Tilling battens
6) Counter battens
7) Face wood
8) Roof cover (roof tiles, schingle)



- It doesn't cause contusion; dissipation like other type of thermal insulation materials placed onto the floor base of the garret; is imputrescible against the effects of dust and dampness and doesn't cause contusion and dissipation like thermal insulation materials and does not lose its value of thermal insulation level. It does not need renewal every few years and keeps its thermal resistance level for the life of the building itself.

- It does let go high rates through the beam rafters and the beam rafters act like a heat bridge like the thermal resistant materials placed in-between the beam rafters.

- The area under the roof, whether to be used as a living area or not is made available for all purposes; hence an additional dwelling to be used or to be sold is created additionally.

- Is applied at a faster pace than roof woods. Saves time and money on workers time.

- The Roofmate PS Boards carries a load of up to 150 kgs.in the area of monopole and between the two beam rafters when size of separation of the board rafters and board thickness are applied as advised above (please refer to ODTÜ test results).

- The bending strength of the thermal insulation boards used for this application must be 600 kPa for safety and the crushing strength 40 tons/m2.

- It functions as roof wood as well as thermal insulation material and therefore the overall cost is lowr.

- Wood consumption is at the lowest level. This way, protects the forests.



MATERIALS WITH THERMAL RESISTANCE (TSE branded and in conformity of TS 11989a). The cap less porous Polystyrene - extruded foam XPS boards used for the beam rafter pitched roofs without roof wood must definitely have armed surfaces (TS 825 standards, official gazette article number of the attachment number 5, dated June 14, 1999, numbered 23725). In the case of some parts of the boards regarding the fixing of the roof tiles for the application of pitched roofs placed on the roof wood or the tilted roof cement being rough, the water absorption ratios must not exceed % 0.5 in volume with the use of full dipped method.

THERMAL CONDUCTIVITY (LAMDA). The rate at the end of aging for 90 days at 10 C must not be larger than 0.027 W/m.K.

DENSITY: Density for the application must not be lower than 36 kg/m3 on the beam rafter without roof wood. Otherwise,it would not be possible to achieve a pressure resistance of 400 kPa and bending resistance of 600 kPa.

PRESSURE RESISTANCE. It must not be lower than 400 kPa at the applications on the beam rafter without roof wood (TS 11989, Class C4).

BENDING STRENGTH. It must not be lower than 600 kPa at the applications on the beam rafter without roof wood. Otherwise, people would not be able to walk on it. Even at these values the thickness of the board and the gaps left between beams rafters must not exceed the values given by the manufacturers.

STRECH RESISTANCE. It must not be lower than 140 kPa at the applications on the beam rafter without roof wood. (This value can be defined as the load at its maximum, which the material can carry for 50 years on a continuous basis under a deformation of up to 2 %. Also, as the load for statistical calculations 140 kPa should be taken as basis instead of 400 kPa).

WATER ABSORBTION. The water absorption rate for prolonged periods using full dipping method must not exceed 0.2 % in volume.

WATER ABSORBTION WITH DIFFUSION OVER LONG PERIODS. The rate of water absorption with diffusion over long periods must not exceed 1 % in volume.

FREEZE THAW. The rate of water absorption using freeze thaw method must not exceed 0.2 % in volume. Also, the reduction in pressure resistance as the result of freeze thaw test must not exceed 2 % (the rate of 10 % as the standard is the upper limit).

WATER VAPOUR DIFFUSION RESISTANCE. It must be between 100 and 200.

a) Change of dimensions in the length and the width must be zero at 60 C and 90 % relative humidity.
b) Change in dimensions must not exceed 2 % under 20-kPa stresses and at a temperature of 80 C.
c) Must not exceed 2 % under 40-kPa stresses and at a temperature of 70 C.

RESISTANCE TO FIRE. Must pass the B2 test first, then must be proven that it has passed B1 class by applying chimney furnace tests and that it has not been dripping. Besides the documents obtained from TSE there must also be certificates granted by the test institutes in Germany.

CAPILARITY. Must be zero.

SPECIFICATIONS OF THE SURFACE. Must be armed (binding).


SIDE PROFILES. Tongue grooved side profiles would prevent the work of heat bridges.
