Sliding Glass Door

Common Problems:

• Improper flashing

• Inadequate vertical offset between the interior and exterior surfaces

• Lack of a bituminous or plastic protection barrier between the aluminum threshold and the concrete or sheet metal substrate

Potential Damage:

Water intrusion into the framing system and living spaces resulting in:

• Dry rot in the wood framing system

• Water-stained gypsum board

• Damaged flooring materials, carpeting and interior furnishing

• Corrosion of aluminum threshold due to lack of protection barrier

Proper Solutions:

• Provide a 1-1/2 inch vertical offset between the interior and exterior surfaces

• Provide a weather-tight, fully sealed or seamless sill/jamb flashing system that protects the corners of the threshold and counter flashes the deck system

• Provide a bituminous or plastic protection barrier between the aluminum threshold and the concrete or sheet metal substrate
