Presentation on different types of Internal Insulation and Cold Bridging products for Hard To Treat Solid Walls.

Transcript of Smart eco hub open day 1

  • Welcome to Enviroform Solutions Open Day April 11th 2014 designed better to perform better
  • A little housekeeping first. We are a no smoking site Please register on arrival You may not proceed to the manufacturing areas unattended Please watch for forklift traffic and keep to pedestrian areas
  • Market Segmentation Social Owner Occupied Heritage Premium Comprehensive, Innovative & Fit For Purpose Retrofit
  • Non Standard Projects Heritage, Public, Commercial & Private
  • Our Integrated Approach. Building Specific Insulation Systems Risk Assessment Wide Insulation Spectrum Robust Cold Bridging Details Primers Adhesives Lime Finishes SIL-T Wall Treatments Infrared Heating
  • Great Partners
  • 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
  • Internal Wall Insulation Internal Wall Insulation Smart Eco Hub Open Day
  • 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 Can we meet U Value Requirement? What do we know about the building? Is the result breathable or not? Vapour Barrier or variable diffusion membrane What lifespan do we expect? Who is setting the standards?
  • 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
  • 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?
  • The Clients Choice? Solid Wall IWI A Vapour Open Breathable? Solution. Or A Vapour Closed System
  • 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 its 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
  • 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 faade 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

  • 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

  • Standard Practice Thermal Laminates 1 Vapour & Thermal Break 2 Thermal looping 3 Thermal Bridging
  • Best Practice Magnaline Slim / MagnaBlok 1 - Vapour Tight Joints 2 - Unventilated Cavity 3 - Unique Fixing Tracks
  • 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 dont then they must state this - OPT OUT
  • Better Designed to Perform Better Our IWI range utilises fit for purpose materials, vapour open/closed, hydroscopic & hydrophobic Unique, patented design features such as MagnaBlok enable faster but more robust insulation / control layers Our finishes can be breathable, buffering or non breathable Uniquely, our experience with aerogel insulation allows us to solve practically every thermal bridge arising Even solid floors can be upgraded - UltraTherm Minimal training required to install No extra cost or time burden on contractor End user benefits every time this is especially important where existing litigation is a factor in a project
  • 2 - Cold Bridging In Solid Wall Insulation Enviroform Solutions design & manufacture truly innovative primary IWI and EWI and Cold Bridging Products using 10mm Aerogel Insulation These products can be utilized and can compliment any SWI system Currently working with the BBA to produce a set of Thermal Robust Details for SWI Products are protected by Patents, both here and in Europe We like a challenge when it comes addressing cold bridging and can quickly turn around designs for Non Standard applications In simple terms we add the Hat, Gloves and Socks to your trousers and jacket to keep your property warm and comfortable
  • 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
