Aluclad windows and sliding door

Karenf168

Hi

I would appreciate any recommendations for sliding door suppliers. We are knocking out the back of the house to put in a 5.5m slider and putting 2 new windows in. I am confused as to the variation in quality. Irish Supploers Vs scandinavian. Our builder thinks aluclad can get squeaky which sounds awful. Would appreciate insights /recommendations by PM. I would like as narrow a frame as possible. Builder also thinks triple glazing in a door that big might be too heavy? Thx in advance
