Roof Insulation
The Airgreen Hybrid System is a must for reducing heat loss, carbon emissions and ensures airtightness.
Combining Home Iso and Air-Reflect provides a cost effective, sustainable solution for all roof insulation applications from flat roofs to warm roofs.
Home Iso is fully breathable and which will allow timber to breathe and will not degrade over time. Air-Reflect eliminates cold bridging and reflects up to 97% radiant which will keep the building warm in the winter and cool in the summer.
Our high thermal performance insulation is the perfect solution for all roof build-ups and will be effective for the lifespan of the building.
Roof designs conform to the BS 5250:2021 and Part L of Irish Building Regulations
Roof Types
FLAT ROOF INSULATION
U-Values
LR membrane + 50mm air gap + 200mm
Home Iso + Air-Reflect 0.15w/m2k
COLD/LOFT ROOF
Cold roof build up consists of Home Iso between and across ceiling joists and Air-Reflect on the underside of joists. From this build up you can achieve a high level of thermal performance and air-tightness with the Airgreen Hybrid System. Design conforms to the BS 5250:2021 and Part L of Irish Building Regulations
U-Values
200mm Home Iso + Air-Reflect 0.15w/m2k
280mm Home Iso + Air-Reflect 0.11w/m2k
WARM ROOF INSULATION
In a steel frame roof Air-Reflect replaces the LR membrane
