I am shocked ...Hi Kieran, thanks for your feedback. I am shocked to hear that polyurethane insulation can interfere one's vision. I never heard that before, even though I knew that it was made from chemicals. Thanks for letting me know. <br /><br />I totally understand your comment on the extra costs, but here probably legislation has to come into play to ensure a decent standard in energy and environmental related terms. People always have to make compromises. Thanks anyway.<br /><br />passive attackAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-5629955157977575799.post-1186715583249425342011-11-17T11:20:39.138-08:002011-11-17T11:20:39.138-08:00Henrick Thank you for your comment.
The insulation...Henrick Thank you for your comment.<br />The insulation type mentioned may be the best type but I have just one or two issues with the type of insulation,<br /><br />The cost can be high compared to traditional insulation. Which as you know is very important in the current economic climate.<br /><br />Also being from a health and safety backround, Polyurethane insulation contain hazardous chemicals such as benzene and toluene. These can pose potential health hazards and are of environmental concern during raw material production, transport, manufacture, and installation.<br /><br />If you do not wear a protective mask or goggles, it is possible to temporarily impair your vision using this type of insulation by(2–5 days)<br /><br />From the article in Denizli 0.0225 m is the insulation thickness being used at the moment, this it is said if up graded to the use of 0.095 m insulation thickness, would reduce the amount of fuel and emissions by 63%.<br />I understand your view on the costs point of view but as i commented on anthonys blog, try selling that idea to a young family who have lost their jobs, It is not just a case of, "Gimme the money now and you will see the results in 5 or 10 years" People may not have the initial lump sum to hand over straight away. I thought it was just worth mentioning.<br /><br />Thanks again,<br /><br />Kind regards,<br /><br />KieranKieran Passivehttps://www.blogger.com/profile/14271483653389126821noreply@blogger.comtag:blogger.com,1999:blog-5629955157977575799.post-72940546745288563822011-11-16T08:15:19.281-08:002011-11-16T08:15:19.281-08:00Dear Kieran,
well structured your evaluation. You...Dear Kieran,<br /><br />well structured your evaluation. You were pointing out that you had an issue with the type of insulation being used. Do you know the insulation type? <br /><br />Further you explain the set up of components for standard walls in Denizli, without mentioning insulation, later you write:"the insulation thickness currently being used in buildings in Denizli is 0.0225 m". Is that from back in the days or still current standard for new build?<br /><br />As you have pointed out, optimum insulation levels depend on pricing of materials and fuel. On the background of climate change you also mention CO2 and SO2 emissions. I wonder if optimum insulation levels could be determined by only looking at a initial cost and running cost comparison. As an initial investment cost will quickly be offset by running cost. A sensible calculation would probably use a payback period of 10 Years. What do you think?<br /><br />By the way, I just learned that good thermal performance (optimum insulation levels)requires an airtight building. The cost for airtighness should therefore be included in the cost for insulation. (According to SIGA.CH average cost for airtightness materials is €450/100m2)Just for anyone interested. Keep up the good work.<br /><br />Passive AttackHpassberghttps://www.blogger.com/profile/12573120920005163348noreply@blogger.com
