QUALITY FEATURES:
The 5-layer veneer board
A 5-layer, AW-glued veneer plywood panel made from carefully selected woods.
Advantages:
- The decorative veneer layer consists of high-quality, sliced – or Fineline veneers, which are joint-glued together as shown. Our recommendation is to shorten the blank at both ends.
- The Moralt external door blank achieves a visual veneer structure on both sides, which corresponds to a door of very high quality.
Sound insulation
Sound absorbers with the best test certificates:
FERRO Acoustic front door blanks correspond to the sound insulation index Rw putty value. There is also the value RwR (calculated value). This calculated value is the value of RwP reduced by the retention value (5 dB for doors). Will e.g. For example, if a sound insulation of 27 dB RwR is required on the construction site, a test value of RwP 32 dB is required. Please request our “ready-to-use element” recommendation.
Flat steel stabilizer
A flat steel stabilizer consisting of two flat pieces of steel grooved into the wood and glued over the entire surface. This works according to the static principle of tension and compression.
Advantages compared to a U-shaped steel and square profiles:
- No thermal bridge due to thermal separation of the two pieces of steel .
- Free of cavities, so no condensation forms inside.
- The flat steel stabilizers do not show on the surface even when the building moisture is high.
- Low weight by avoiding unnecessary steel joints.
Frame
Unmistakable handcrafted charm: Our stiles and rails are made of solid, carefully selected - or laminated, finger-jointed timber.
LVL core middle layer
The LVL core with upright-standing annual rings, consisting of approx. 5 mm wide peeled veneers glued together. The optimum strength is attained through offset joints within the inner core layer.
Advantages:
- Highest Highest strength values from the offset laminated joints.
- Optimum surface smoothness thanks to the even distribution of the individual veneers and the consistent position of the annual rings.
