Roadstone manufacture the most extensive range of High Strength concrete blocks in Ireland from the highest quality aggregates produced at our own quarries. Blockwork and masonry blocks have been the proven mainstay of modern construction techniques in Ireland. They are available in both metric and modular size ranges and are suitable for plastering
Group 1 (solid) 13N/mm², 18N/mm², 24N/mm², 36N/mm² and 48N/mm²
Group 2 (cavity) 13N/mm², 18N/mm² and 24N/mm²
(I.S. EN772-1 fm dry).The blocks can be integrally coloured for identification purposes, texture can vary due to differing source materials and production methods.

Fire Resistance: Euro code 6 – I.S. EN 1996 Design of Masonry Structures – Part 1-2: General Rules – Structural Fire Design, defines the methods and calculations to determine the fire resistance of concrete block walls. Table N.B3.1 to table N.B3.6 of annex A, Roadstone Blocks have a Class A1 Fire rating
Thermal Properties: I.S. EN 1745 Masonry and masonry products-Methods for determining design thermal values .Table A3 Typical Thermal Resistance “R” value of 100 mm solid block = 0.084 (m²K/W). Typical Thermal resistance “R” value of 215 mm cavity block = 0.210 (m²K/W)
