Soffit & Underfloor Insulation
Sprayed polyurethane foam has been used in the UK since the mid 1970’s to insulate a wide variety of residential, commercial and industrial premises and Isotech has extensive experience going back to this time.
Cast in-situ concrete construction methods will often dictate that where a development incorporates a car park undercroft within the design, the insulation is best fitted to the underside of the soffit. An application of sprayed foam is often far more practical and effective than specifying a mechanically fixed board system. Suspended timber floor voids can be similarly treated provided adequate access is available for installation.

Case Study
The material is based on a CFC free two component foam supplied to us by the most respected manufacturers in the industry. We are approved installers of their British Board of Agrément and Local Authority Building Control certificated systems.
It has a Class 1 surface spread of flame rating and conforms to all relevant British standards.
A Class 0 fire rating can be achieved with the subsequent application of an intumescent fire protective coating in construction situations where the insulation would otherwise be left exposed.
We have developed a close working relationship with the technical services department of our suppliers and they are pleased to be involved when additional information and advice is required, such as U-value calculations and condensation risk assessments.
The material is processed through a Gusmer proportioning pump fitted in our van. This machine is driven by compressed air from our towed compressor and requires an electricity supply to power switches and the internal heater block.
A twin heated hose (210 feet maximum length) is fed from the van to the point of application. The two components mix at the tip of the spray gun under pressure and are reacting as they are applied to the soffit substrate.
The closed cell foam has exceptional bonding characteristic, sets hard in minutes and has a core density of 32-36 Kg/m3.
The depth of the foam can be varied from 25mm for anti-condensation treatments to in excess of 100mm, where higher levels of insulation are required.
