Roof Insulation – Foam-Lok Spray foam

Maximize Your Investment

Roof Insulation - Spray Foam Insulation - DublinAir moves in and out of a home through every hole, crack, and crevice. Roughly one third of air infiltrates through walls, ceiling, and floors.

Adding an advanced insulation system is necessary to achieve optimal building performance. Foam-Lok™ spray polyurethane foam is that advanced insulation system. Spray foam insulation can maximize a home owner’s investment by sealing the building envelope to stop conditioned indoor air from escaping and prevent unconditioned air from entering a home. Air exchange in and out of a home is a leading cause of escalated energy bills.

An environmentally friendly home is a great benefit for you, your family and the environment. Take an active role in helping reduce greenhouse gases, thus slowing the effects of global warming. By properly sealing your home, you reduce the amount of energy that is needed to produce electricity and the carbon emitted into the environment.
FOAM-LOK open cell spray foam insulation is a water blown polyurethane foam and is completely inert when installed. With a thermal conductivity of 0.037 W/mk it can be installed as an independent product to achieve regulatory U-Values and airtightness requirements in most construction buildups. It provides a cost effective, fully breathable insulation solution.

It is installed by our trained team to ensure that installations are carried out in line with the appropriate insulation and ventilation regulation requirements. It will provide a sealed thermal and airtight layer, eliminating heat loss and creating a comfortable healthier indoor environment.

Foam-Lok At A Glance


FOAM-LOK can be installed between rafters to the required thickness in order to provide a particular level of insulation or U-Value. The open cell spray foam can be sprayed proud of the roof rafter to the desired thickness or can be cut flush with the adjacent timbers to allow for plasterboard fixing.

As with all insulation types FOAM-LOK can be applied to breathable roofing felts when a counter batten is present above the felt and below the tile / slate batten in accordance with Irish and UK Building Regulations. This allows for the necessary ventilation layer above the vapour permeable roofing felt. In circumstances where the roof is not “counter-battened” it’s necessary to install rafter slide to the underside of the felt. This effectively provides a separation layer between the foam and felt to allow for ventilation as required by regulation.

FOAM-LOK is BBA Agrément approved and holds an ETA (European Technical Approval) with NSAI Agrément pending. FAOM-LOK has achieved a Class E Euroclass fire classification as a stand alone product (without plasterboard lining) making it the highest performing spray foam insulation of its type.
