“WALLTITE spray foam injection allows the insulation to be retrospectively fitted to an existing building. There are many other benefits to this product, for example, it creates an air seal by filling the gaps and as a result, the heating system will work more economically and efficiently. Warmth is increased in the external walls and this will greatly reduce the levels of condensation in the building.The installation will also significantly reduce any noise transfer at Crescent Primary School. All of these benefits are incredibly important for a schools project like this.”
