Workshop: Strategic insulating

Thermal Envelope

Thermal envelope – strategic insulating.

More than insulation, thermal inertia and hygroscopicity. Tackling cold spots to remove discord and create harmony. Double and secondary glazing, solid and suspended floors, lofts and voids. Internal IWI, external EWI and solid wall insulation SWI.

When: Saturday, 18th July. 12-5pm
Where: 14 Richmond Road, Montpelier, Bristol BS6 5EN [Map]
Cost: Free (Booking essential)

Agenda

  • Principles – thermal and vapour resistivity, thermal inertia and hygroscopicity.
  • Tools – guide rail saw, drill and driver, trowel and hawk.
  • Projects – fleece, board, lime mortar, lime plastering and wallpapering

Summary

The third in this series of home improvement workshops, we’ll look at the thermal envelope. More than u-values and vapour gradients, we’ll take look at the traditional thermal envelope, thermal inertia and hygroscopicity. Understanding breathable, synthetic, natural and traditional materials as well as architectural detailing and hygrothermal passive heat recovery.

External weather patterns, local topography, solar aspect and evapotranspiration all effect the thermal envelope, as well as occupant behaviour, and internal weather. Warm moist air is conveyed to cold spots, insulating some parts of a building can makes other parts relatively colder causing damp.

We’ll also be getting to grips with some tools, learning transferable skills and tackling some basics yet essential home maintenance. We’ll be working our way through the tool box this series, learning top tips and proficiency with every tool you’ll need around the home.

This month vapour control part 1, hygrothermal passive heat recovery, the relationship between energy and damp. More than internal insulation we’ll be capturing energy from moisture, preventing heat loss whilst solving a damp problem. We’ll be learning how to prepare, mix, and cast Hemp Lime to existing masonry.

  1. This was a thoroughly useful and enjoyable afternoon. Learnt a huge amount about hemp casting as well as getting some hands on experience. I feel confident enough to apply what we covered at home. Thanks Simon!

  2. it was really satisfying in a number of ways. I really enjoyed finding out about the finer details of hemp and lime, and then working with others to do the wall was great fun! Once everyone knew the process something clicked and away we went……There was lots of time to ask questions; nothing is set…it was all done in a spirit of exploration really. Very refreshing. It was a lovely learning experience, thank you.

  3. What a great afternoon. The preliminary chat over a cup of tea gave us all a chance to ask questions, find out about the materials and learn a little about why and how they are used.

    Working as a team to mix and apply the hemp and lime was not only fun but also gave us the opportunity to continue the discussion into the techniques that Simon uses and why they are useful. I certainly felt an immense amount of satisfaction at the end of the day when I realised how much I had learnt. Thanks Simon!
