Advantages
Technical Data
GUTEX Multiplex-top®
- Extra covering or taping of the joints is unnecessary if used with 22, 28 and 35 mm thick boards for pitches greater than 15° or for 18 mm boards if the roof pitch exceeds 20°.
- Suitable as temporary roof covering (max. 3 months)
- Makes structures wind-tight
- Adhesive nail tapes or sealants are not required.
- Reduces thermal bridging
- Guaranteed by Germany's Association of Roofers
- Consistently uniform board dimensions make installation quicker and easier
- Homogeneous, single-ply construction
- Ideal for upgrading the thermal insulation of existing structures
- Superior thermal storage capacity provides outstanding insulation against heat in summer and cold in winter
- Improves acoustic insulation
- Regulates humidity and is vapour diffusion permeable
- Manufactured from wood, a sustainable natural resource
- Recyclable
- Biologically safe (natureplus© certified)
- Made in Germany

InstallationAccessoriesPlease follow the following instructions carefully:
Installation
- Always store the boards in a dry place. Only install the boards if they are dry.
- Always install the boards so the side with the marking is exposed on the exterior of the building.
- Max. rafter distance (centre-to-centre):
- Install the boards lengthwise with exact fit for tight joints.
- Avoid walking on areas between the rafters.
- Immediately install battens after installing boards.
- Adhesive nail tapes or sealants are not required.
- Avoid cross joints.
- Do not use damaged boards.
- As a rule, the boards install perpendicular to rafters.
- Stagger butted side joints with the next row’s joint being centred no closer than the next rafter.
- All seams and roof joints must be properly sealed with the GUTEX Joint Sealing Kit to prevent the ingression of rain, e.g.
- Always install the boards so that their tongues point upwards.
- The boards do not provide suitable structural support or stability.
- GUTEX Multiplex-top is not a load-bearing structural element (e.g. snow)
- Avoid exposure to high levels of moisture (e.g. wet screed) on the interior sides of the boards.
- Vacuum off the dust in accordance with applicable workplace safety regulations or practices.
Excerpt from "Guidelines for Roofing with Tiles"
- If the roof pitch does not exceed the minimum roof pitch and there are not more than three of the requirement-raising factors present, it is not necessary to tape the board joints.
- If the roof pitch is 8 ° less that specified standard, and up to three of the requirement-raising factors are present, it is not necessary to tape the board joints.
- If the roof pitch is 8 ° less that specified standard, a sub roof is required.
- Factors that may raise requirements are: roof pitch, construction, use, climate and local regulations/conditions.
