Does coastal exposure change the specification?
Yes — Clydebank's exposure to wind off the Clyde means frame and roof fixings are specified to a higher wind-loading rating than an equivalent inland Glasgow build.
In practice that means wind-rated glazing seals, closer fixing centres on roof panels and additional mechanical fixing at the wall plate and eaves. Driving rain also makes the flashing and seal detail at the junction with the house more critical than on a sheltered inland plot.
