Issaquah Plank & Panel and Metal Siding
High-Performance Reclad
Project summary
This Issaquah 1970s home was spacious but drafty, with a tired façade and envelope issues. The owners asked for a contemporary Northwest design and better comfort/efficiency. Synapse delivered a new plank-and-panel exterior, upgraded the weather-resistive and air barriers, and integrated new Milgard windows—combining modern curb appeal with a tighter, more durable envelope.
Scope of work
-
Concept & 3D design for a modern Northwest plank-and-panel façade
-
Removal of existing cladding; substrate inspection and repairs
-
New WRB + air barrier with taped seams and proper penetrations
-
Rainscreen assembly for drainage/ventilation
-
Integration of Milgard windows with flashing, returns, and trim
-
Final detailing at corners, eaves, and transitions; homeowner walkthrough
Materials & details
-
Cladding: modern James Hardie plank & panel system (fiber-cement or composite panels with complementary lap planks)
-
Windows: Milgard units, integrated to manufacturer specs
-
Envelope: continuous WRB/air barrier, rainscreen gap, kick-out flashing
-
Trim/edges: clean, modern profiles; coordinated soffit/fascia lines
Why this approach
A plank-and-panel mix delivers the clean, contemporary lines the clients wanted while keeping maintenance low. Pairing a continuous air barrier with a rainscreen and properly flashed Milgard windows reduces drafts and moisture risk—meaning better comfort, efficiency, and durability in Northwest weather.
Before / After highlights
