Spray Foam Insulation

Lapolla FOAM-LOK Open Cell Foam

FOAM-LOK FL500 open cell spray foam insulation provides a cost effective fully breathable insulation solution. Manufactured by Lapolla Industries it is installed by a nationwide network of trained and registered contractors each of whom undergo regular audit by to ensure that installations are carried out in line with the appropriate Part L insulation and Part F ventilation regulation requirements. All contractors are SEAI approved under the Home Energy Saving scheme.

Spray Foam Insulation expands to fill all voids creating a sealed thermal and airtight envelope. The application of spray foam creates a highly effective seal against air leakage, the number one source of energy loss in a structure. In addition to improving durability, indoor air quality and comfort, spray foam insulation when paired with other responsible materials can reduce heating costs by 30-50% compared to traditional insulations, reducing the burning of fossil fuels and lowering CO2 emissions. Lapolla’s FOAM-LOK spray insulation is an 8kgm3 open cell foam that expands when installed to 100 times its original size to completely fill all voids in the walls and roof of the building.LAPOLLA FOAM-LOK logoIt will provide a sealed thermal and airtight building envelope, eliminating heat loss and creating a comfortable healthier indoor environment. Less energy will be employed with FOAM-LOK insulation to heat or cool the building saving up to 50% on monthly costs and keeping conditioned air inside and unconditioned air out.

  • FOAM-LOK spray foam is an air barrier but not a vapour barrier and will manage moisture migration through the wall or roof structure.
  • FOAM-LOK provides excellent thermal performance and is effective in reducing the u-value of the roof or walls of the building. For the purpose of u-value calculations the thermal conductivity of the product may be taken as 0.037W/mK.
  • Warm N’Cosy Homes always recommend that the building be considered as a system. When using FOAM-LOK insulation we recommend that controlled fresh air is designed into your building by means of Passive ventilation or Mechanical heat recovery systems.
