One of the most common ways to make an oak frame home is to encapsulate the timbers in SIP or other cladding materials including brick and render. But if you want to have exposed wood inside or outside the property, even both, then this can be achieved in a few different ways.
One example is to use half-width timbers that mean the large structural beams and posts can be seen inside and outside but others are hidden beneath the building panels. Secondary timbers are only visible on one side so this allows an uninterrupted layer of insulation on the walls. Known as 3i panel system, this can achieve a U value of 0.25 for the entire wall, not just the central panel of it. this two-layer system means that elements such as barge boards, soffits and fascia’s can also be added after the encapsulation, so they don’t pierce through the panel system.
