Internal Wall Insulation (IWI)

Heat Loss is one of the major issues in properties pre 1940. With solid brick walls, there is no cavity that can be filled with insulation. This can cause up to 35% heat loss through the walls alone. To help counter act this, we can install insulation, be that internal or external. By doing either of these options below, you will be adding a number of benefits to your property.


Insulation Plasterboard Applied over existing walls & skimmed.


To insulate a wall internally, we can install insulation plasterboard in the form of Thermal XP, Thermal PIR Boards or Jackoboard . The insulation part of these boards can be made from a Extruded Polystyrene Foam (XPS) or Polyisocyanurate Foam (PIR).  These are bonded to standard plasterboard to allow for a skimmed finish. These boards can be installed to masonry, stud or existing walls. To install these boards to masonry backgrounds, we use a multi purpose adhesive instead of a gypsum adhesive. This will help to reduce drawing moisture through the wall in the event the wall has no cavity.



External Wall Insulation

When installing external wall insulation, we are proud to say we are a Weber Recognized Contractor. That means when we install a EWI system, it's done to a specification, supplied to us by weber. This means you know the system has been installed correctly.

The main External Wall Insulation system we use is Webertherm XM. This is a multi-Layer system, starting with the insulation it self. This is covered with a 6mm adhesive render coat with a mesh laid within. When dry, this can be finished with a silicone textured finish similar to thin coat rendering or a brick-effect.

There are 2 different types of insulation boards that can be installed.
