I would like to thank you for the excellent service we had concerning the insulation o a new roof light, although a brand new house, the builders' contractor who originally installed the previous roof light was totally installed incorrectly ie to BS 5516 standards, you only need to ask your fitters what it was like. I would like to express how impressed i was with Linda your sales contact and James, Ross your fitter who was extremely professional and faultless in the installation. Yours sincerely Philip Mace
