About Dartmoor E-Shield
Your trusted partner for high-performance external wall insulation systems in Devon and beyond.
Our Story
Dartmoor E-Shield Insulation & Supplies Ltd. is a locally-owned contractor and merchant based in Okehampton, on the northern edge of Dartmoor National Park, Devon.
We specialise in designing and installing high-performance external wall insulation (EWI) systems built around graphite-enhanced EPS and high-density XPS boards that achieve λ-values down to 0.031 W/m·K.
All systems are BBA-certified, meet BS EN 13163 standards and can be finished with breathable silicone or acrylic render, brick-slip slips or timber cladding.
In our online shop you'll find EPS/XPS boards (20–200 mm), mineral adhesive and basecoat, alkali-resistant mesh, PVC corner beads, colour-matched silicone renders and made-to-measure aluminium/PVC window sills.
Orders placed before 2 pm ship the same day from our Devon warehouse; installer packs include free U-value calculators and fixing charts.
