Thermal performance criteria have changed significantly over the last couple of years, notwithstanding, you may have the highest specification but detailing and workmanship can mean all the difference between the success and failure of an installation.
Any competent contractor can carry out this work; we are offering a new design service through our web site.
Through this service, we can provide specifications, construction details and provide details of what you should look for in the installation.
We trust you found this of interest,
Jeremy Wedge MIstrutE CEng on behalf of Loft Conversion UK
