Breathability in buildings NBT
This scientific document shows the breathability figures of many different building materials and explains why drylining using non breathable materials is a bad idea on page 24.
Moisture Buffering Effect of Wood Products
This document shows how different wood products can keep the internal climate healthy.
German Health warning against drylining
This document shows that only natural hygroscopic products are allowed when drylining a house in Germany, all other products are banned. They checked out mouldy houses that were drylined 15 years previously and decided to do something about it.
RockShield
BBA cert for External Rockwool insulation also showing U-values for different thicknesses of Rockwool.
Ext Ins with EPS slips
This document from Finland shows how the wall is allowed breathe when using External Polysterene insulation by putting on 10mm strips of EPS onto the wall to allow air movement between the insulation and the wall.
Long Term effect of Ext Insulation
This German study shows that External Insulation checked after 30 years holds up very well and has a similar 60 year life span to cement render.
Go to page 13 to read the Summary and Conclusions!
Passive House Guidelines SEI
This document showing the Passive House guidelines has some bad detail where they put Quinnlite blocks below the dpc level which is wrong because they soak up moisture. The insulation levels required for building a Passive House in Ireland make interesting reading though. We have been asked by SEI to update these drawings.

Journal of building physics convection in atticspaces
Lightweight insulation in your attic is not as good as heavy insulation, a scientific study.
Lecompte paper_partial fill cavity walling
This Scientific study by LaCompte shows that due to Thermal Looping in a cavity wall, the effect of 70mm of Kingspan is reduced to the insulation level of 35mm of Kingspan. Check the U-value changes on the table at the end of page 2.
Estonia Poroton Details
This Estonian Document shows good details for those building with Poroton. The Agreament Cert from FBT shows Cold Bridges where the walls meet the floor and where the walls meet the roof. If you are building with Poroton it is logical to use our foundation system as the wall/floor Cold Bridge is totally eliminated.
Ytong Decrement Delay
This document from Ytong explains Decrement Delay quite well. Ytong blocks are similar to Quinnlite and are not suppose to be used below the dpc level.
Wind Chill
This study shows the effect of wind on the U-value of the insulation in a roof in Austria. The Austrians at least make an attempt to make their roofs wind tight but we leave them completly open here. I presented this document to the Part L review comitee which I am part of and they decided to continue allowing wind to blow through the insulation in our roofs. Maybe they think we don't get any wind in Ireland!
Scientific study of Cavity Walls
This study shows there is limited risk to full fill cavity walling and examines Thermal Looping. Filling the cavity with foam is dangerous though.
Heraklith
This strong breathable board made from a 40mm dense Rockwool Lamella sandwiched between two 5mm Woodwool boards is ideal as an insulating external skin for a Closed Panel Timber Frame house and easily takes a thick layer of plaster. It allows the Timber Frame house to breathe and cuts out the Cold Bridges at the studs substantially improving the U-value of the wall. It also has a 1 hour fire rating.
