“We used Marlin for windows and steel style doors and internal screens using Alitherm Heritage products on our recent self build project. Marlin are not local to us but provided an excellent service from quotation, advice, redesigns and with very detailed comms throughout. The windows and doors are the talking point of our entire build. Adrian from Marlin said that windows become the eyes of the house and I didn’t forget that – our eyes are simply stunning. Would highly recommend.”
