From closed-cell physical cross-linked polyolefin foam and foil-faced duct insulation to structural thermal break strips, we supply elite thermal control for commercial buildings, AHUs, and industrial pipework.
Advanced closed-cell polyolefin foam with reinforced aluminium foil facing.
Structural thermal breaks to eliminate cold bridging in metal framing and facades.
High-density thermal insulation for chilled water lines, valves, and fittings.
Custom-profiled insulation panels and pre-cut kits made to exact measurements.
Where standard roll widths or thicknesses fall short, we fabricate Thermobreak panels and thermal break components to precise dimensions — eliminating waste and ensuring seamless thermal envelope integrity.
All thermal insulation materials supplied by DM O'Shea comply with rigorous fire safety, low VOC, and thermal conductivity standards to guarantee maximum energy efficiency.
