Hi Darren I just thought I would write to tell you hoe delighted we are with the insulation you installed at our caravan. 

We decided to have it done as we were so happy with the double glazing.  The insulation has made such a difference, even the lino in the bathroom feels warm to the feet. 

We haven't needed any heating on yet. Thank you so much for the good workmanship.

Regards
Olga
