Timber

PINE – Is a soft wood and can be coloured using white or yellow, this timber is very light in weight and highly natural, this is a popular timber in Europe. It is not as dense as hardwood, but resists well from weathering (i.e. rain water and UV sun light).

MERANTI – Is a popular hard wood and is used for the external joinery. This timber comes from Southeast Asia, and has good levels of outdoor durability. This timber can be found in low-lying rain forests and in low mountainous regions, and offers some of the best options for hardwood, in terms of the product’s cost effectiveness

TIPS while taking measurements for box sash window!

It has been recommended for new sash windows to allow for a 84mm frame jab, and for frame jambs to be placed on each side and inserted into the wall and in turn which allows the sash cord mechanism to be covered. Regarding the external view, it has been suggested that we allow a 20-30mm of the visible to be facing, whereas the rest is hidden.

During new openings, when the catnic lintels are installed the facing frame-head can be reduced from 84mm to 40mm (it is the frame’s minimum thickness of sliding sash windows). From an external point of view, the overall framing will look symmetric.
