Aug/2006

Technical data
Mechanical Values Thickness: Width: 1250 mm Length: 2000 mm Weight: ca.. 11,5 kg/m² 15 mm

Material
Micronal® PCM SmartBoard™ reinforced with coated fibreglass mesh. Transport The boards are flexible and should be carried on the building site edge up. Storage Store dry onSmartBoard™ pallets.

Preparation
Cutting: Score Micronal® PCM SmartBoard™ with a knife, break along the score and, if necessary, clean up the edges with a rasp-plane. Micronal® PCM SmartBoard™ can also be cut with a keyhole saw. Note: Prevent from dust exposure. If necessary use respiratory mask. Do not cut with an electric circular saw or fast turning angle grinder. - Risk of dust explosion -Avoid grinding swarf inhalation -

Edges: Long edges flattened (AK) reinforced with fibreglass mesh Short edges cut (SK) Thermic Values: Operating temp. 23°C or 26°C Latent heat capacity ΔH: ca.330 kJ/m² Spez. heat capacity: ca.1.20 kJ/kgK Heat conductivity: ca. 0.134 W/mK

Jointing and finishing
Joint compound • Hand-fill the joints with joint compound (e.g. Knauf Ready Mix Lite) and jointtape (e.g. Knauf Fibre Tape). Preparation • Sprinkle joint compound into clean, cold water until its level is just below the surface of the water (e.g. max. 2.5 kg Knauf Ready Mix Lite in approx. 1.9 l water). • Without adding further ingredients, stir to a thick, creamy consistency with a filling knife. • Do not mix joint compound with other materials as this may significantly alter itsproperties. Amount of material: Joint compound: Skimming: approx. 0.3 kg/m² as required General: • Plaster over any visible screw heads. • Apply fibreglass joint tape to cut-edge joints as well. Jointing: Apply a thin layer of joint compound and lay fibreglass joint tape along the joint. Before proceeding, the joint compound must be hard and dry. Skimming: An additional coat with a suitable finishingplaster (e.g. Knauf Multi-Finish or Knauf Board Finish) is recommended if the surface has to meet special requirements. Application temperature and weather conditions • Jointing should be carried out only when Micronal® PCM SmartBoard™ are no longer undergoing any no significant length changes, e.g. as a result of changes in humidity or temperature. • The room temperature must not be below about10°C. • Where mastic asphalt flooring is to be laid, do not joint Micronal® PCM SmartBoard™ until the floor has been laid. Finishing Lightly sand the jointed areas, if required, when they are dry. Prime the surface (e.g. with Knauf Wallboard Primer) before applying a coating (e.g. paint or wallpaper).

Construction + Installation
Walls: construction andinstallation
Metal stud walls consist of simple studwork lined on one face or both with Micronal® PCM SmartBoard™. The studwork is connected around its perimeter with adjoining structural members. Insulation, electric wiring and plumbing may be installed in the wall cavity. Expansion joints in the main structure must be repeated in the stud wall construction. Expansion joints are required every 15 m orso in continuous walls. Substructure • Apply sealant or sealing tape (two beads) to the reverse side of profiles for connecting the SmartBoard™ to adjoining structural members. Where sound proofing is required, carefully apply sealant according to DIN 4109, Suppl.1, Section 5.2. Porous sealing strips such as sealing tapes are generally unsuitable for this purpose. • Where a ceiling span deflectionof ≥ 10 mm is expected, the ceiling should have a floating edge. • Fix edge profiles to adjoining structural members with suitable fixings. Spacing of fixings 1 m; at least 3 fixings to walls. Fixing method for solid adjoining structural members: rawl plugs (e.g. Knauf Nailable Plugs). For hollow-core structural members: special fixing elements suitable for the material. • Insert the C studs...
