1. An Introduction to the NIA and Insulation Neil Marshall

2. Represent manufacturers and installers –Wall Insulation - CWI, EWI, IWI, Hybrid –Loft/Roof Insulation –Draught Proofing/Air Leakage 170 members - GB and NI Full service TA –Promote the benefits of insulation –Range of membership services –Industry representation –Work in partnership with like minded organisations Maintain Standards –Membership criteria, –Code of Professional Practice Who we are

3. Where does the heat go? 45% of heat lost through uninsulated solid walls 33% of heat lost through uninsulated cavity walls 25% of heat lost through the roof/loft space 20% of heat lost windows and doors

4. The Benefits of Insulation Solid Wall Insulation Save around £375 a year on heating bills Reduce (CO 2 ) emissions by around 2 tonnes each year Cavity Wall Insulation Save around £110 a year on heating bills Pay back in just 2 years Reduce (CO 2 ) emissions by around 560kg each year Loft insulation Save around £145 a year on heating bills Pay back in under 2 years Reduce (CO 2 ) emissions by around 800kg each year

5. The Opportunity Over half the existing housing stock in the UK has inadequate levels of insulation! 7m properties have solid walls that are not insulated 8m properties with uninsulated cavity walls Around 13m lofts with inadequate insulation Most people have some loft insulation but it is not sufficient – to comply with modern standards it should be 270mm deep + 4.5m micro/SME businesses

6. Carbon Emissions Reduction Target - 2012 Community Energy Saving Programme - 2012 Energy Company Obligation - 2013 Green Deal – October 2012 Residential and commercial buildings Market Drivers

7. Cavity Wall Insulation Permanent, maintenance free home improvement, lasting the life of the building Most homes built from 1920 onwards have cavity walls Cavity wall insulation fills the cavity between the inner and outer walls - reducing the amount of heat that is lost

8. Cavity Wall Insulation Small holes are drilled into the outside walls and CWI material is blown into the cavity Holes in the brickwork are filled post insulation 3 types of material are used mineral wool/polystyrene beads/foam CIGA (Cavity Insulation Guarantee Agency) issue an independent 25 year guarantee covering defects in materials and workmanship

9. Loft Insulation Loft insulation reduces the amount of heat escaping through the roof by providing a layer of material with air pockets that trap the heat The recommended depth of loft insulation is 270mm (mineral wool) There are three types of insulation used: mineral wool quilt/blown mineral wool/cellulose and polystyrene boards

10. Loft Insulation Mineral wool quilt is the most common material used Quilts are laid down between the joists then another layer of insulation is `cross-laid' to cover the joists Insulation makes the house warmer but the roof colder so it is important to insulate tanks and pipes in the loft space

11. Internal Wall Insulation Solutions Built up insulated framework Solid Wall Insulation Vapour control layer / Plasterboard Studs

12. Laminated insulated plasterboard Solid Wall Bonded insulation Plasterboard Internal Wall Insulation Solutions

13. Thermal insulation on a roll Internal Wall Insulation Solutions

14. Multifoils / Aerogels

15. Internal Wall Insulation Suitable for installation where the external wall appearance cannot be changed (planning restrictions) Can be utilised where there is insufficient external clearance to install external wall insulation It can be installed on a room-by-room, single façade or whole house basis, as part of a full refurbishment plan

16. External Wall Insulation Adhesive Decorative Render Finish Insulation Insulation Fixing Render with Reinforcing Mesh

17. Very high levels of insulation possible. No internal disruption. Effective for new and existing buildings. Building fabric is protected from the weather (extends buildings life). Overcomes cold bridging, condensation and dampness. Enables building appearance to be improved / modified. External Wall Insulation

18. Hybrid Approach Front appearance retained using IWI Side/Rear and any extension can benefit from EWI The same techniques are adopted for standard IWI/EWI
