​Although we have been applying these coatings for in excess of 40 years now it's still surprising to us the amount of people that still do not know about them and assume that masonry paint is the answer to their wall problem. It still creates a lot of interest as soon as a house is masked  up with people asking whats happening. the following will give you a brief insight in what these coatings are about and  why they need  to be applied by  specialist crews using high performance spray pumps .

INSULATION VALUES OF GUNEX
Apart from 100% waterproofing your external walls GUNEX offers a reasonable amount of insulation compared to masonry paint or plain render


If your main concern is insulating your external walls you have several options depending on the construction of your property, Cavity walls can be injected with several types of insulation  ( polyester beads being in our opinion the best option ) GUNEX is then a good top up  to this keeping the external skin warm and dry.


If your external walls are solid brick / block the the only option is external thermal boarding but this does add approx 75 Mil  ( 3"inches ) to the exterior and is a major renovation undertaking  and expensive. Apart from that it's also very impractical on the majority of houses in the Uk, requires Building control permission and can destroy the character of the property.
For the majority of clients using our service its to stop damp, and the constant maintenance of painting every few years, the insulation benefits of GUNEX is a bonus for them. 


If you are intending to receive a survey and quotation from us we have a simple on site demonstration that shows how GUNEX aids in keeping your property dry and slows the heat loss through your external walls.
This property below shows an older solid wall house in desperate need of weatherproofing and insulating. On consulting with the client we was shown black mould in all bedrooms and the lounge. As fast as the client was painting the internal walls the mould was back. Our survey showed that the external walls was saturated with water and was never drying out . You can see why from a picture taken during the works  ( Pic 3 ) even on a summer's day the walls was getting soaking wet  from a summer rain  shower, imagine these walls during in the winter .
As the walls was built in solid 9" brick & Stone   the clients only option was insulation  and weatherproof the external walls, but adding 75Mil  boarding to this property would ruin the character and would need extensive alterations to the building structure and roof. Because of this and  the costs involved the client decided to go with the GUNEX system . The photos below speak for themselves from a cold wet home to a warm, dry, and  beautiful house to be proud of.
