Question 1
Describe in three sentences the problems that have been experienced with Inner-Seal siding.Selected Answer: 1. Like any manufactured wood product, the edges of the siding are vulnerable to water penetration.2. Rainwater can be absorbed at butt joints, nail holes, wall penetrations, intersections with other materials such as door and window frames, and at the bottom edges of the panels3. When OSB siding absorbs moisture, it swells and the plies will separate. This allows more water penetration and supports growth of mold, mildew and fungus.Correct Answer: 
The siding has prematurely swelled, rotted, buckled, checked, cracked, delaminated or supported fungal growth when exposed to normal weather conditions. This may be a result of improper installation, but a settlement has been reached and financial help is available for homeowners with damaged siding until January 2003. Butt joints in the material are particularly vulnerable to water absorption.Response Feedback: [None Given] Question 2
Describe in two sentences a siding nail and why it has special characteristics.Selected Answer: The nails are often round-headed siding nails. The round heads are designed to help promote good drying at the front and back of each board, by keeping the boards slightly apart. The round head holds the overlying board away from the board below.Correct Answer: A siding nail has a rounded head to hold the board on top away from the board underneath. This promotes good drying potential.Response Feedback: [None Given] Question 3
Explain in two sentences the one-nail versus two-nail controversy with respect to lap siding.Selected Answer: 1 nail introduces cupping, resulted in cracks.2 nail caused expansion and contraction, resulted in cracks.Correct Answer: One nail may promote cupping. Two nails can cause shrinkage cracking as the board is pinned.Response Feedback: [None Given] Question 4

What is the effect of vines growing on wood siding?Selected Answer: Vines hold water and reduces the drying potentialCorrect Answer: Vines hold water, and reduce the drying potential.Response Feedback: [None Given] Question 9
What material is Inner-Seal?Selected Answer: Oriented Strand Board with was-impregnated paper coveringCorrect Answer: Inner-seal is OSB with a wax impregnated paper covering.Response Feedback: [None Given] Question 10
Why is drying potential important with respect to the life of wood siding?Selected Answer: Quick drying prevents rot, mold and mildew. Good drying potential is also important to stop cupping. If the front of the board is dry and the back is wet, the board will tend to cup.Correct Answer: Because the sun drives moisture into the wood, so it needs to escape from the backside of the siding. The faster and more completely wood dries, the longer it will last.Response Feedback: [None Given] Question 11
