But it needs to be understood selection, grade, cut, mill and finishing has to be just right, that’s why expertise are important in the preparation of Canadian Cedar.
After 64 years we are still learning as new finishes and formula’s need to be tested for their ability not to change the stability of the timber. The timber has to be a special grade too start, then has to be cut to grain show spec’s, drying time needs to be exact and no hot oven kiln drying. Milling can only commence when the moisture in the timber is at the right level. Finish coatings needs to be 100% dry or any of the above will cause instability in about 15% of the material.
It takes expertise’s and experience to make blind lath and finished product and years of testing. So when we are asked do your blinds warp the short answer is no! Much less than 1% because the person assembling missed the grade and did not reject the slat.
