Our flat roofing insulation products are manufactured to the highest standards, utilizing cutting-edge technology and precision engineering.
Flat Roofing Solutions
Tapered EPS Insulation
Expanded Polystyrene (EPS) offers an exceptional balance of thermal performance and structural integrity, with increased compressive strength variants available to meet specific loading requirements. The material's inherent flexibility allows for fabrication to suit roof falls from 1:30 to 1:120 specifications.
The thermal performance of EPS ranges from 0.032 to 0.040 W/mK depending on density, while compressive strength options extend from 70kPa to 200kPa. This versatility makes EPS particularly suitable for large span roof areas where lightweight construction is essential.
Applications
Large span roof areas
Complex drainage schemes
Refurbishment projects with limited structural capacity
Cost-effective industrial building solutions.
Tapered PIR Insulation
Polyisocyanurate (PIR) insulation represents the pinnacle of thermal performance, with thermal conductivity as low as 0.024 W/mK, making it one of the most thermally efficient insulation materials available. This exceptional performance allows architects and specifiers to meet increasingly demanding thermal requirements while minimizing insulation thickness.
PIR's versatility extends to its compatibility with various waterproofing systems. The material is available with tissue facings for torch-on applications, foil facings for enhanced vapor control, and glass tissue variants for compatibility with adhesive systems. Our manufacturing capabilities allow for pre-bonding of PIR boards to thicknesses over 600mm, creating highly efficient single-layer solutions.
Applications
New build commercial and residential projects
Refurbishment schemes
Warm roof constructions
Hybrid roofing systems
Green roof applications
Tapered Mineral Wool Insulation
Our mineral wool insulation utilizes non-combustible stone wool technology, delivering exceptional fire performance classifications alongside superior acoustic properties. With non-combustible classification to EN 13501-1 Class A1 and a melting point exceeding 1000°C, the material maintains structural integrity even under extreme fire exposure.
From an acoustic perspective, mineral wool provides superior sound absorption properties and effective airborne sound insulation. Technical specifications include thermal conductivity ranging from 0.034 to 0.040 W/mK, with density options from 90kg/m³ to 150kg/m³.
Applications
Schools, hospitals
Public buildings
Multi-residential developments
Commercial buildings requiring high fire resistance ratings
Heritage buildings.
