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.
Retaining Heat within the property, there by improving comfort.
Reducing the risk of damp/black spot mold.
Reduce Heating Costs.
Improve soundproofing.
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.
These can be installed onto Masonry, Stud or Existing Walls.
When installed to a masonry background, a multi-purpose adhesive is used instead of gypsum adhesive. This helps to reduce drawing moisture through the wall.
Insulation plasterboard comes in arrange of different thickness.
Jackoboard can be used on window/door reveals, due to there small thickness. This helps to reduce cold spots round openings.
PIR Boards come with an added vapour barrier, this helps to reduce the risk on condensation.
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.
EPS is made from expanded polystyrene. This is the most cost effective option available when installing a EWI System. It comes in thicknesses of 30mm-200mm. This insulation is very lightweight, non-toxic and is completely recyclable.
MFD is made from a non-combustible mineral fiber wool. This is supplied in the same thicknesses as the EPS. It is slightly more expensive to install than EPS, however this insulation gives you a highest reaction to fire classification required. As a added benefit, it also has noise absorption properties.
