INTERNAL WALL INSULATION (IWI) IN DONEGAL
Internal wall insulation, frequently shortened to IWI and also known as insulated dry lining, is fitted to the inside surface of a property’s external walls.
It can be a suitable option for solid wall homes, properties without an appropriate cavity or buildings where external insulation is not practical. The system may use insulation backed plasterboard or insulation fitted within a purpose designed internal framework.
A professional assessment is essential before installing internal wall insulation. We consider the condition and construction of the walls, moisture levels, ventilation and condensation risk. The installation must also be carefully detailed around windows, doors, floors, ceilings and adjoining walls to reduce cold bridging.
Internal wall insulation can affect window reveals, sockets, radiators, skirting boards and the usable dimensions of the room. We will explain these practical considerations clearly and include the relevant work within your quotation.
When correctly designed and fitted, internal wall insulation can help create warmer rooms, increase internal wall surface temperatures and reduce heat loss through cold external walls
