OSB or CBPB? What is better?
Let us remind you: CBPB
are durable cement-bonded particleboards produced from a mixture of wood chips, cement, water, and mineral additives. OSB
are oriented strand boards. They are manufactured in multilayer mats consisting of wooden strips bonded together with different resin adhesives, synthetic wax, and boric acid. One mat consists of several layers of cross-oriented strips.
OSB and CBPB have similar technical specifications:
- Mechanical stress resistance. They can be easily processed.
- Coating with OSB and CBPB ensures street noise isolation.
- They are not affected by high humidity, while additional finishing is not necessary, etc.
OSB boards traditionally used in frame construction are indeed cheaper (at the time of writing this article such boards did cost cheaper, but right now the price rose significantly)
, but they didn't show good performance. Pressed strips glued with adhesives and resins are unhealthy for a human as they are a source of phenol and formaldehyde. On the contrary, CBPB is an ecologically safe material. Its name is self-explanatory. It doesn't contain any harmful volatile substances.
CBPB is suitable both for exterior and interior finish, and doesn't require any wet works – all works can be performed even at sub-zero temperatures.
CBPB has a smooth and even surface which is certainly an advantage for the finishing process because CBPB is a perfect base that doesn't require any preparation works: you can glue wallpapers, paint it or apply decorative plaster at once. The biggest boards manufactured at the plant are 1.2×3.2m weighing up to 80kg. It's not a light material but three or four workers can easily deal with it without any lifting equipment.
A house made of CBPB is perfect for year-round use. This material is vapor-permeable, extra moisture will naturally leave the house through the walls. Nevertheless, we advise using plenum ventilation in such a house or regularly ventilate the house to ensure a comfortable microclimate and air exchange.
What material is required to construct such a house?
Wooden frame, mineral wool for wall, floor, and roof insulation, wind and vapor barriers, as well as CBPB for exterior and interior. Please see the gallery with real examples of frame houses built in Krichev by JSV Belzarubezhstroy where CBPB was used for exterior and interior finish. (photo: www.onliner.by)
