Semi detached house with North facing external timber stud wall approx 65mm thick needs rebuilding

Anonymous user 09/03/2024 - 3.08 PM

My house has a north facing front elevation that has very little direct sunlight throughout the year. The structure of the wall is part cavity brick to underside of the upper floor then approx 65mm studded timber cladded wall to roof. The wall has a 3m wide by 0.6m deep bay from ground level to roof and so the cladding applies to 3 faces to the upper level. I am wanting to replace the existing insulation (if any) with Kingspan and the external cladding with a k render for a long lasting look and ease of maintenance. However, my concern is whether a k render will achieve this and have read elsewhere online that stains are difficult to remove and can be affected by algae and potential flaking. My question is, Are there regulations in place for the required build up of a 65mm thick external studded walls for domestic dwellings? If so where can they be found? Is the application of a k render recommended for North facing walls of this type? Where can I find modern alternative solutions to the external feature if not?
