Everwarm use "Beetafil" which is U.F. (Urea Formaldehyde) foam system. After being professionally installed the cavity walls are left with a self-supporting foam blanket, which will not shrink or settle down the wall in time. Moreover, the foam will not drop below the DPC and fill the footings, and will not fall out when alterations are being carried out (i.e. walls opened up for extensions, vents, patio doors, etc).

By giving the highest insulation value the foam will contain the warmth generated by various heating systems (gas, electric, solid fuel).
