The exterior cladding of your home is made of many components, which if installed correctly, protect your home from the environment by keeping moisture from penetrating your home.
When siding is installed, whether it is a vinyl, wood or a fibre cement product, certain requirements must be followed to ensure a quality installation. The following are minimum standards per Alberta Building Code.
- All penetrations into your home must be treated with flashings which are designed to move water away from the penetration. These flashing are required to have an end dam which again stops the water from flowing off the ends of the flashing and down the edges of the penetration.
- There must be a weather resistant barrier (ie. building paper) installed behind the siding product. The barrier should be installed in a shingle manner with the top layer overlapping the bottom layer a minimum of 4" on all horizontal joints and 9" on vertical joints. The barrier should be installed over the flashing, under the barrier that is located at the bottom of all windows and behind the insulations stops. This barrier should be free of tears and rips or any damage should be repaired prior to being covered by the exterior cladding.
- Vinyl siding expands and contracts so it is important that when your siding is being fastened that the fasteners are not secured too tightly, to allow for expansion and contraction.
