Exposure : If your home is exposed to severe levels of wind-driven rain, this is the primary cause of damp. You are at a higher risk of moisture penetration if you are in an environment, which is susceptible to driving winds. However, you are at less risk if your property is in zone one or two.
Poor construction : If the home’s external walls are poorly built, cracks in brickworks or rendering are signs of poorly constructed external walls. Hiring a professional construction company with experienced staffs saves you from future building defects like poor pointing, downspouts, cracks in the outer leaf of the wall structure and leaks from faulty gutters.
According to the Building Research Establishment (BRE), the maximum exposure for retrofit cavity wall insulation installation is in zones one and two.
Zones three and four are exposed and they are at risk of wind-driving rain, which causes problems in the cavity.
Zone 3 includes; Blackheath, Walthamstow, Acton, Tooting, Muswell Hill, Woolwich, Balham, South Tottenham, Catford, Leyton, Cricklewood, etc.
Zone 4 includes; Barking, Woodford, Finchley, Totteridge, New Malden, Abbey Wood, etc. Some of the challenges associated with cavity wall insulation are poorly fitted insulation, wall tie corrosion, and spray foam insulation. The risk of installing retrofit cavity in your homes cannot be overlooked, that is why CavityExperts4u can give you comprehensive support and advice in cavity wall insulation challenges.
