The foam can be applied to various depths and has a K-value in the range of 0.025 to 0.028W/mK. When sprayed to a depth of 85mm the U-value of a typical roof with 100mm fibreglass at ceiling level is reduced from 0.34W/m2K to 0.16W/m2K, surpassing current Building Regulations.
- High Insulation values
- Systems can be applied to various depths and have K-values in the range of 0.025 – 0.028W/mK
- Brings thermal performance up to current Building Regulation requirements
- Save the equivalent of more than one tonne of CO2 per annum by reducing energy consumption
- Prevents condensation: complies with Approved Document F ‘Alternative Approach’ for non-ventilated roofs. Calculations are made using the method in BSEN ISO 13788:2002 (and BS5250 Appendix D): Code of Practice for Control of Condensation in Buildings
- The foam acts as a protective barrier, preventing the ingress of wind-driven rain and snow
- Will provide more resistance against storm or impact damage – increasingly important with the onset of erratic weather conditions
Your chosen installer will perform a survey prior to installation to check suitability, i.e. the roof should be structurally sound with any defects resolved prior to installation.
- Residential roofs
- Steel, asbestos, aluminium roofs
- Flat roofs
When spray-applied foam is applied to the underside of the roof this bonds slates and tiles to each other and to the structural or supporting timbers.
- This is particularly beneficial where there are signs of nail fatigue
- Great for weatherproofing (against ingress of rain, storm damage prevention, etc)
