Redering on eml fix to timber

Timber frame structures are natural materials…. They have moisture in the timber.
Cladding is weatherproof, if directly applied to a timber frame it traps the moisture in the structural timber, as well as having the dew point directly behind it (or maybe even in the structure), adding more water to the structure directly!

Moisture, moisture, moisture …. All trapped within a natural material where a cladding is directly applied… eventually it will cause the timber to degrade and rot!
The timber frame is structural, so the structure will collapse

This has happened….! The UK building regs, insurance providers and inspectors demand an open (top and bottom) cavity between cladding and natural structures… Think about it, cavity between timber frame and Blockwork as well….

This is a major issue in countries with damp and colder environments….
The issue gets worse when you get moisture on your car / van in the morning - that is dew. But, in a building without a cavity allowing it to drain or vent away, it will be stuck in the structure for a long time…

Sorry buddy, been known about and regulated for decades!

Yes - S&C render to EML has been used on TF for years as well… it will crack and fail as the S&C is heavy and brittle….
Why modern, thin coat, lightweight, flexible renders and suitable exterior grade, low or zero organic content boards have now taken over in this application!

….But, when S&C is / was used, it had a vertical batten creating a drained and ventilated (top and bottom) cavity, breather paper or membrane, then EML and render

Nhbc say its omitted from building regulations?
 
Well there all the same one states one thing and another states another thing
So I've now asked there in spector to supply me with his specifications but thanks for your reply much appreciated
