Can DGI insulate properties that have raked or thin mortar joints?

Some properties that have thin or raked mortar joints are now eligible for *free cavity wall insulation as part of the government’s CERO grant funding scheme.

Mortar joints are the spaces between the bricks used in the construction of external walls that are filled with mortar. In the majority of cavity wall constructions they are a set size however, in some cases, the joints may be thinner than the standard or may be recessed to a degree that would lead to damage being caused if traditional installation measures were used.

This has led to such properties being classed as hard to treat (HTT) as insulating them is more difficult then traditional properties. This used to mean that insulating such properties was not viable due to the damage that could be caused, however Domestic & General Insulation’s Thermascopic Bead Lance eliminates this issue by ensuring that fewer drill holes are needed to insulate the property. This provides our installers with the tools they require to ensure these properties are brought up to current energy efficiency standards.

In the majority of cases you will be eligible for *free cavity wall insulation if your joints meet one of the following criteria:

As accredited installers, Domestic & General are able to insulate properties that have thin or raked in addition to providing a free survey to determine if your property is eligible in the first instance. Simply call us free on 0800 138 7207 or use the button below to send us an enquiry.
