8. Our Methodology
“Build Specific Insulations Solutions”
• Communication is fundamental to the success of any project
• The “Health” of the occupants and the “Safety” of the building
fabric
• In many cases the value of the upgrade measure is a small fraction
of the job cost or eventual monetary or perceived value
• Risk Assessments form part of our daily lives so why exclude it from
our retrofits
• Our solutions are fit for purpose, optimize Gross Internal Area and
sustain breathability where appropriate

10. IWI Simple Questions to start…
• Do the project stakeholders
• understand the impact of the
proposed upgrades?
• Do they want to know!
• Is the proposed upgrade solution fit
for purpose?
• Is it achievable with the conditions on
site?
• Does it address the risk of damage to
(a) the building and (b) health of
human users?
• Will a simulation / analysis help to
reveal problems?
• If so then how reliable is the other
material information?
~10 nm

standards?

11. Risks with Internal approach to Solid Walls
• Solid walls are often quite damp in Winter & Spring
• Brick, mortar and some stone can wick water to the internal face through
capillary transport
• Pre retrofit heat loss will help to dry out the wall during the wet season
(January to December in Ireland)
• The application of IWI will interrupt the heat flow and associated drying,
leaving the wall at risk of being very wet during freeze thaw events
• The resultant damage can be serious
• U Values should be carefully considered & thermal bridges must be
treated

12. Risks with Internal approach to Solid Walls
• Thermal bridges must be treated
• Appropriate materials should be used to limit heat loss but save
space where necessary
• Does the project require a vapour barrier – usually on the warm
side of the insulation
• But in this case where does the vapour go during late spring to late
autumn – reverse diffusion is prevented!
• Any gaps in the insulation or vapour control layer may be
detrimental to the project success – not today or tomorrow but
eventually – consider a Park Lane or heritage project, is it worth the
risk?

13. The Client’s Choice? – Solid Wall IWI
• A Vapour Open “Breathable”? Solution.
• Or
• A Vapour Closed System

14. Vapour Open “Breathable” Solution?
• For a material to be truly “Breathable” it must display all of the
following characteristics.
1 Vapour Permeable – can transfer water as vapour
2 Hygroscopic – ability to absorb water as a liquid
3 Capillarity Active - ability to release water as a liquid
through it’s pores
• In short the materials can deal with the formation of water due
to vapour condensing and direct it in the path of least resistance
– either to the outside or inside face of the solid wall

15. Vapour Open – Wall Preparation
• It is imperative that all materials in the existing wall to be insulated
must be “Breathable”
• Wall containing Non Breathable materials must be completely
removed – eg gypsum, sand & cement, paint etc.
• Once complete we recommend treating the external façade with
one of out SIL – T products to aide the short and long term safety of
the fabric
• Internal walls need to be finished with a minimum 9mm Lime Parge
coat to provide an airtight and hygroscopic layer
• The system has to be finished with lime based plaster
• The lime plaster has to be finished with a natural or mineral paint

17. Vapour Tight Solution – IWI Solid Walls
• Vapour tight systems are the most common solution used on the market
today, usually in the form of Thermal Laminates – Insulated Plaster Board
• Considering a “Non Breathable” wall cannot cope naturally with the
movement of water then these critical factors MUST all be present in an
IWI system
1 Continuous Vapour Control Layer – Board Joints
2 Continuous Insulation Layer – No thermal breaks
3 Thermal Bridging due to multiply fixing
4 Thermal Looping due an unventilated cavity
5 Adequate treatment of thermal bridging – reveals, returns & floors

21. Why are existing thermal laminates Approved?
4. General
4.4
When insulating solid walls, particularly older exposed walls, designers should consider the extent
to which the wall and components in the wall can tolerate the lower temperatures and prolonged
drying time resulting from the application of the insulating drylining. Care should also be taken to
assess the risks of interstitial condensation forming on thermal bridges that cannot be effectively
insulated.
4.7
It is essential that proper care and attention is given to maintaining the integrity/continuity of
vapour control layers (VCL).
4.10
The Installation of an insulating drylining system requires careful detailing around doors and
windows to achieve a satisfactory surface for finishing. In addition, every attempt should be made
to minimise the risk of thermal bridging at reveals and where heavy separating walls are attached
to the external wall.
Existing IWI Certificate
“It is Critical that there IS a continuous vapour control layer”
“Opt in or Out – how will BIM work with this type of inadequate information?”
“All cold bridging CAN and Should be addressed – Opt In or Out”
Certification must state - OPT IN- how products or systems deal with these critical areas - If they don’t then they must state this - OPT OUT

• In simple terms we add the “ Hat, Gloves and Socks ” to your trousers and jacket to
keep your property warm and comfortable

25. What is a cold (heat) bridge?
• Heat loss through a localised area where the primary insulation layer is interrupted or
significantly reduced
• Difficult but not impossible to treat in solid wall insulation
• Become more significant where the building fabric has been upgraded
Effects of a cold bridge
• Rise in heat energy demand
• Indoor surfaces at lower winter temperatures
• Increased risk of surface condensation
• Risk of damages to building units, leading to vacancies &
rehousing costs
• Danger of mildew, causing serious health threats, potential
litigation
• Complaints, withheld payments, reputation damage

26. Why focus on thermal bridging?
Detail IWI EWI
Typical 36.3% 49.36%
Improved 17.78% 14.77%

27. Untreated Cold Bridges and bad design contribute
greatly to - The Performance Gap
Measurements of thermal performance of newly erected dwellings in UK:
measured vs. predicted overall heat losses (W/K)
Figure from [Wingfield et al., 2011]
Annex 58

28. Why is this not more of an issue in SWI?
• Lack of Knowledge & Training in cold bridging and ventilation
impacts
• Certification of systems and what details they cover?
• Complexity in dealing with areas – Space
• Lack of suitable cost effective solutions
• BUT…
• Enviroform Solutions are now in the unique position to provide
unique products to tackle all these critical areas and therefore
future proof the insulation upgrade and fabric of the building

29. What is Certified – Best or Standard Practice?
4. General
4.7
The Fixing of rainwater goods, satellite dishes, clothes lines, hanging baskets and similar items is
outside the scope of this certificate.
6. Thermal Performance
6.3
The systems can contribute to maintaining continuity of thermal insulation at junctions between
elements and openings. Details shown in Figure 2 will allow use of the default psi values for
Accredited Construction details in Emission rate calculations to SAP 2009 or the simplified Building
Energy Model (SBEM). Guidance on limiting heat loss at junctions can be found in.
Northern Ireland – Accredited Construction Details (version 1.0)
11. Risk of Condensation
11.1
Designers must ensure that an appropriate condensation risk analysis has been carried out for all
parts of a construction, including at junctions, openings and penetrations to minimise the risk of
condensation. The recommendations of BS 5250:2011 should be followed.
