September 1, 2004 - editor. Pattaya Thailand home construction, home building. How roof eves are finished off. GRC sheeting applied to roof eves. How wood foundations are prepared to support the grc sheeting sub roofing material. Suitable materials for the support frame: why coconut wood should not be used.

GRC (glass reinforced cement) sheeting is applied to a wood foundation to form the underside of the roof overhang (eves). Below is a sample of how the underside of the eves are prepared for the grc sheeting and how the grc sheeting is then applied. The example also covers the grc sheeting application to form a ceiling over a carport.

The main thing to watch for with grc sheeting is that the wood foundation is made of the proper wood. The wood should be 1 1/2" by 3". Using coconut wood, which is commonly done to squeeze a cent, is not recommended. It will degrade quickly if it comes in contact with moisture and is not very durable. The coconut wood which is often used (as shown below) is about 1/2 the size of the standard 1 1/2" by 3" wood.

Make Sure Not to use Wood Like This

Here are a couple of shots of coconut wood framing. If your buying a house you might want to get a look under some grc sheeting to see if this type of wood was used.
