Summary

STEICO – ecology

Ecology – CO2-Reduction

www.co2-bank.de

Per roof truss: about 3,5 – 8 to CO2 longtime buffering by the construction

„additional volume“ by

building envelope (HFD, 80mm): 12 m³ � 4 to CO2

STEICO – Schallschutz

Sound insulation

”massive” insulation(density 45-50 kg/m³)(density 45-50 kg/m³)

High sound absorption

Multilayer building elements � “decoupling”

Noise reduction Rwrup to 52 dB

STEICO – Hitzeschutz

Summerly heat protection

Low thermal conductivity λ

High specific thermal storage capacity cp

High density ρ

� low themal guide number a

� excellent phase shifting

WDVS – Verarbeitung

Boards have to be stored horizontal, dry and plain on at least 3 supports

At least two (three) packages may be stored one upon each other

Intact foil has to be left until mounting the boards

Package leaflet has to be kept� allows internal allocation to plant datas

Storage and transport

Exposed surfaces should be kept clean

Edges should be protected from damages

Damaged material has to be removed before mounting


handle pasty products (buckets, tubes) frost-free, bagged cargo dry

Protect from free weathering (e.g. tarpaulin)

pasty products have a limited storage time� usually about 12 months

Storage and transport of plaster products

Rendering profiles have to be stored horizontal, as possible with the original outer packaging

Fugendicht-cartridges must also be handled frost-free

Always use cap anchor together with original screw and insulating plug� fastening system


Careful checkup of the timber frame / subsoil� plane, dry, clean, thick enough to take fasteners

Check up grid of frame constructionT/Gsmall, dull hochk. 62,5 cmfrom 60mm T/Gbig 83,3 cm

only grinded surfaces may be plastered (dull board)

Mounting of the boards

N/F-Platten sind beidseitig geschliffen („Innenseite“ mounted towards stud)

Damaged edge-material should be removed before mounting

Joints have to be mounted as tight as possible� use of a bat to take care of the edges

Tongue should be mounted to the top


Carefully planning of necessary protection towards splash water� special plaster products or changing to „perimeter“-insulation

Interlocking of boards not necessary in edges� adequate fixing on both wall alignments, dull front faces

Protect front face from longtherm weathering� window parapet


joint offset at least 25-30 cm� no crossing joints

No joints directly at the edge of a window/door

Assebly-connections always must have a suitable joint-sealing-tape� Hanno, Illbruck

joints greater than 2mm have to be filled with STEICOprotect Fugendicht >2 bis 6mm Fugendicht ca. 20mm tief>6mm WF - adaptor

Surface imperfections have to be mended (adaptors, Fugendicht)

if necessary, dull joints may be sticked together (Fugendicht)

Offsets in the surface have to be grinded with a rough emery-board

Preparation for plastering

Offsets in the surface have to be grinded with a rough emery-board

Surface has to be cleaned before rendering (sweeping with a brush)

all connections of components have to be proofed concerning durabletightness

humidity of boards must be lower/equal 13% before rendering� calibration factor 1.5 compared to solid wood

Board surface, normal weathering: 3 to 4 weeks� preserved front edges

Ready reinforced plaster layer: ca. 5 months� alternatively: thin initial plaster layer 2mm

Postprocessing of the unplastered board surface ca. 5 months� protection by roof oberhang, tarpaulins …

Weathering without plaster

� protection by roof oberhang, tarpaulins …

humidity of boards has to be checked before plastering

joints and surface offsets have to be reworked

WDVS - Zusammenfassung

Wood fibre boards (e.g. STEICO protect) are used as

plastered base boards for many years

Physical advantages especially affect timber-based

buildings

Ecological aspects and the demand for sustainability

push the use of timber-based systems also for

renovation purposes

Conclusion

system oriented problems solutions allow robust details
