## Abstract

A stack of lumber (10) is inhibited from checking as it dries by being sheltered with an air pervious plastic material (16). The plastic material has a material to air density of greater than 50% to restrict sunlight and rain and less than 90% to allow adequate ventilation.

## Claims

### Claim 1

A method of inhibiting the checking of lumber as it dries wherein the lumber is sheltered by an air pervious plastic material having a material to air density of between 50% and 90%.

### Claim 2 (depends on 1)

The method of claim 1 wherein the lumber is sheltered with plastic material having a material to air density of approximately 80% wrapped about the lumber.

### Claim 3 (depends on 1)

The method of claim 1 wherein the lumber is sheltered with plastic material spaced from the lumber having a material to air density of approximately 60%.

### Claim 4 (depends on 1)

The method of claim 1 wherein the lumber is sheltered with plastic material comprised of polymeric material selected from the group consisting of polyethylene and polypropylene.

### Claim 5 (depends on 1)

The method of claim 1 wherein the lumber is sheltered with a woven air pervious plastic material.

### Claim 6 (depends on 1)

The method of claim 1 wherein the lumber is wrapped with the air pervious plastic material.

### Claim 7 (depends on 1)

The method of claim 1 wherein the air pervious plastic material is draped in spaced relation from the lumber.
