Insulation work to 5 Hillfoot Terrace, Tarbert

The Association has recently under taken work to insulate under the floor of the above property with Lapolla Spray Foam. The work was carried out by NMU4 Contracting Ltd through our approved contractors Kevan Brown Ltd.

The work was undertaken to increase the insulation properties of the house and to provide a barrier to the earth solum underneath.

The work was done in a matter of hours, causing the minimum of disruption to the tenants and has had the desired effect of allowing the tenants to keep their house warmer in a more efficient and cost effective way.
