Renovating a basement, garage, or attic in Surrey? If spray foam is part of your plan, a proper spray foam thermal barrier should be too. BC code generally requires foamed plastic insulation to be protected from the interior of the building, and inspectors check for it. Planning the barrier from day one saves time, money, and stress later. Our guide covers approved materials, room-by-room requirements, and the most common inspection mistakes, so your Surrey renovation stays on schedule and on budget. Western Insulation installs spray foam to Canadian standards across the region. Learn more: https://westerninsulation.ca/spray-foam-thermal-barrier-bc/
