Pavatex Diffutherm Timber Frames Benefits... |
|
NBT
Diffutherm System is for timber frame
buildings externally finished with render. Diffutherm
systems use NBT Pavatex woodfibre boards over the
outside of the frame in a continuous layer.
The racking
board is fitted on the inside of the structure, acting
also as both the airtightness and the vapour control
layer, in a fully breathable construction.
Externally
a Baumit mineral based, thin render system is applied
directly to the Diffutherm boards.
Internally
we recommend a service void between racking board
and plasterboard for effective airtightness control
and easy service alterations.

System Application... |
| econstruction
products Timber Frame Diffutherm System can be used
with any conventional timber frame design, provided
that the racking board is fixed on the inside of the
frame rather than the outside. The same limitations
apply as to all timber frame applications. The Diffutherm
system has a good fire rating and is suitable in many
situations requiring fire resistance. Contact econstruction
products for further details.
The significantly
lower cold bridging through studs and y-values(psi)
means that the Diffutherm system outperforms traditional
timber frame systems. The insulation layer is continual,
including into reveals and returns.
