Multifoils like SuperQuilt are becoming more popular for insulation applications. Because of their high vapour resistance attention is needed, when installing such layers to standard roof structures, made of timber.
This detail can be found in many houses during the construction stage. I guess that in the most cases someone will put the window board or the kitchen work top on top and everything is covered. The occupier is wondering thereafter where the draughts around the window do come from.....
From 01/01/2019 the revised Building Regulation for Connservation of Fuel and Energy (Part L) requires lower maximum values for the air permeability of new buildings and deep retrofits. We think it´s a first step into the right direction, but the mandatory values for air tightness are still too high, especially for common technologies like heat pumps and heat recovery ventilation. Our aim is and will remain max. 1.5 ACH (air changes per hour), wherever we´re involved in the air tightness.
Please notice the last shipping for online orders will be made on Wednesday, 19/12/2018. Orders thereafter will be shipped on Wednesday, 02/01/2019 due to a business break of our shipping partner GLS from 24/12/2018 until 01/01/2019. GLS will need this Thursday and Friday to ensure the delivery of all shipped parcels within Ireland. Local customers can collect their orders between Christmas and New Years Eve in our store in Tralee.
I´m astonished everytime about the ignorance (or is it lack of knowledge maybe) of some Irish companies, working in the construction trade. For what purpose have been the building regulations introduced, beside ignoring?
As already stated before - modern windows require a certain fitting standard, to develop their full insulation performance. Take more attention to the installation work, to prevent an unwanted window change after a short period. A good window with proper fitting will last for 30 years and longer. Prevent the replacement of so called "future proof windows" after 10 years, caused by poor fitting standards
Concrete blocks and timber battens, as mostly used for the support of the door threshold in new builds, are old fashioned and inappropriate. They won´t fulfil the criterias for a permanent door support with thermal break.
Belgacoat Air Tight Paint is more than a standard layer for air tightness. Both versions passed a Radon test recently, which creates a serious alternative especially for Radon barrier strategies in existing houses.
