Cold walls? Start before winter.

Plan the wall before choosing foam. Follow the exact product’s temperature and protection requirements.

Fix the leak before adding insulation

Repair water entry and flashing. Foam should not hide an active leak or replace exterior drainage.

Draw all four control layers

Trace water, air, vapor and thermal control through windows, floors and the roof connection.

Find what the foam could cover

Locate wiring, pipes, boxes and future access. Keep required services visible, protected and repairable.

Match the foam to the actual wall

Check substrate, layer limits, application temperatures, target thickness and intended role.

Leave room for protection and checks

Confirm required barriers, local review and inspection timing before concealing the work.

Keep proof while it is visible

Record product, lot, conditions, thickness, photos and corrected defects before the wall is closed.

Ready means the whole wall is ready

Proceed only when water control, continuity, instructions, protection and inspection agree.
