Egger DHF Vapour Permeable Sheathing Panel
DHF Vapour Permeable Sheathing Panel
DHF VAPOUR PERMEABLE SHEATHING PANEL
EGGER DHF is a vapour permeable, moisture-resistant wood fibre board with CE marking in accordance with EN 14964 and EN 13986.
Due to the formaldehyde-free gluing and the use of exclusively natural, conifer wood (sawmill by-products), the boards are particularly environmentally friendly and low in emissions.

ADVANTAGES
This is what makes the EGGER DHF vapour permeable sheathing panel stand out – its advantages in application
The areas of application and properties of DHF panels are listed in the CE declaration of performance (DOP-506). With its properties, the Egger DHF is the suitable vapour permeable sheathing panel for the cladding of roofs and timber frame construction walls.
-Rainproof vapour permeable sheathing panel , pucture-proof and windproof – three important functions are ensured in a single operation with the EGGER DHF panel. -Two months of free weathering of the boards as temporary roofing between March and November give you security in the construction process. -DHF panels are puncture-proof and create a walkable roof surface - for higher safety on the construction site.
-With the tight tongue and groove profile, the board plane is windproof without additional measures. -The DHF panel is quickly installed, thanks to optimised tongue and groove profile and the printed nail grid.
-The guaranteed raw density of at least 600 kg/m³ in combination with a large-area installation with a few joints has a positive effect on the sound insulation and fire protection of building components. -With the different storey-high formats, stiffening timber-frame construction walls without horizontal joints can be realised. -As a solid and stable board, the EGGER DHF offers additional protection against extreme weather events such as storms and hailstorms, even during the construction period.
DETAIL
TONGUE AND GROOVE PROFILE
The optimised tongue and groove profile allows for a better and a fast installation, allowing the user to save time and money. The asymmetric, conic profile ensures, on the one hand, that water can run without problems across the board joint, and creates, on the other hand, a windproof structure. For a rain- resistant installation on the roof, the edge must always point with the tongue to the ridge.
HAIL SAFETY
If the roof cover is damaged by hail, the DHF- board below provides reliable protection against water. During construction, the DHF-board also ensures hail protection until the final roof cover is completed.
RAIN RESISTANCE AND OUTDOOR WEATHERING
DHF-boards offer thoroughly tested rai resistance. DHF-boards can be used up to a roof pitch of 14° without additional measures. In the case of roof pitches between 10° and 14°, the tongue and groove joints must be covered with additional tape in order to achieve rain resistance. Nail sealing tape is not necessary when using DHF-boards.Boards without reinforcing function can be weathered outdoors for two months as temporary roofing between March and November. During the winter months, outdoor weathering should be limited to a maximum of two weeks

VAPOUR PERMEABILITY
DHF-boards have low resistance to water vapour diffusion. With a μ-value of 11, for the available board thickness of 15 mm there is an sd-value of less than 0.2 m. In combination with a vapour control layer on the interior of the components (e.g., OSB 3 boards), safe and durable structures can be constructed with low condensation risk and high drying potential. Vapour barrier film on the interior is not generally necessary when using DHF-boards
FLOOR TO CEILING FORMATS
The formats of DHF-boards are optimal for use on the roof or on the wall. With board lengths of 2,500 mm, 2,800 mm, and 3,000 mm, timber frame architectural boards can be constructed for different floor heights without horizontal joints. The set of formats matching our OSB boards simplifies the planning and the manufacturing of roofs and walls in timber frame construction.
NAIL GRID
The DHF-board is quickly installed, thanks to the printed nail grid aiding assembly. It is stamped on the upper section of the DHF- board in the divisions of 31.3 cm and 83.3 cm (for the axial dimension 62.5 cm). Thanks to
the nail grid, no additional marking is necessary during assembly. This also simplifies installation in the case of deviating raster dimensions. Only the first nail is placed and the DHF-board is fastened parallel to the line print.
