Herringbone roof decoration method

Two practices: the first method is to do a horizontal secondary ceiling. The main purpose of the ceiling is a heat insulation, there is a decorative effect, but also easy to install the layout. Note: horizontal secondary ceiling to try to deepen the space of the second level to look grand. The second method is to learn from foreign roofing methods, the top of the full thermal insulation treatment, after the completion of a layer of decorative panels (general logs can be, but must be dry to deal with). This decorative effect is to ensure that the upper part of the space is large, a little bit of ecological flavor, its space treatment also appears to be diversified, such as installing a ceiling fan or large chandelier, etc. have a better expansion of space. The disadvantage is that the cost may be a little higher.
