STEICOspecial dry
Combined sheathing and render board
Sheathing board
As much as 25 % of all household heat losses occur through the roof. In dwellings where an attic roof has been converted to a habitable space, it is not always possible to insulate the roof from the inside in order to meet new energy efficiency regulations.
Often rafters are not deep enough in their own right to accept the desired depth of insulation. STEICOspecial dry has been designed to be laid on top of the rafters, offering the desired insulation values with the least disruption to the inside.
Key advantages
- Insulating board from the dry process with thicknesses up to 200mm
- Particularly low thermal conductivity, excellent protection against the cold
- Reduces thermal bridging particularly vapor permeable for increased construction security in renovations
- Extra thick panels especially for renovation use
- Can be used in conjunction with STEICO ai-injected insulation systems
- Ecological, environmentally friendly and recyclable like wood

More about STEICOspecial dry
STEICO insulation – the pay off
A non insulated roof in an old building is not only a ‘cash guzzler’, but also results in cold internal surfaces. This in turn can lead to an uncomfortable air movement in the room.
A roof with 140 mm of STEICOflex 036 and 60 mm STEICOspecial dry will have up to 90 % less energy demand when compared to that of a non insulated roof. A warm ceiling also give a feel good factor.
Immediate weather protection
When tackling roof renovations with traditional materials, it is usually necessary to offer immediate temporary protection in order to preserve the rooms below from the elements.
STEICOspecial dry with its Tongue & Grooved profile can offer immediate wind and rain protection for roofs of pitches over 16˚ without additional materials, (this can be achieved for roofs with shallower pitches with some additional measures). STEICOspecial dry gives immediate protection against the elements, with up to 4 weeks protection on renovation projects and exposure of up to 12 weeks on new build projects permissible.
Protection against moisture
The combination of rain protection and openness to diffusion ensures maximum protection against moisture.
Excellent heat protection
Thanks to their particularly high heat capacity, STEICO special dry insulation boards delay and minimize heat transfer in summer. The result: cooler rooms even in the summer heat
Excellent insulation properties in winter
The so-called lambda value (λ) is important for protection against the cold. The lower the value, the better the insulation performance. With a nominal value of λD 0.04, STEICO protect dry has low thermal conductivity that can currently be achieved with roof insulation made from renewable raw materials.
A lower lambda value allows thinner insulation layers and enables greater energy savings.
Proven fire protection
In the event of a fire, STEICO insulation boards produce little smoke. The insulation boards do not melt and do not drip burning from the facade.
Very good sound insulation
Where insulation systems made of rigid foam can even degrade sound insulation, STEICO insulation boards make a valuable contribution to a quiet living atmosphere - thanks to their special fiber structure
