Recent slim-frame aluminium casements installs across the NP11 postcode tell us exactly what works for Crumlin property stock — and what to avoid. What sets Crumlin apart on a survey is the housing mix. Crumlin overlooks the Ebbw Valley and was once home to the famous Crumlin Viaduct. Traditional valley housing here benefits greatly from energy-efficient replacement windows. The 1857 viaduct that once spanned the valley was the highest in Britain — today's residents inherit the same exposed valley brickwork, where multi-chambered uPVC and well-sealed composite doors dramatically cut draughts and damp on classic mid-terrace stock. On a aluminium casement install here we typically specify OW-70 and OW-80 Origin systems with slim 70mm and 80mm sightlines, which maximises the glass area on bay windows and bi-fold flanker units without losing thermal performance. All RAL colours available with no upcharge, including textured and dual-colour finishes. Newbridge and Pontywaun are part of the same daily run for our installers — saves you waiting for a callback. No subcontractors, no commission-only sales reps — survey by an employed surveyor and install by our own fitters. 20-year frame guarantee — the longest in the residential aluminium window market.

Aluminium windows deliver the slimmest frames and largest glass areas of any window material. Their natural strength means frames can be incredibly narrow while still supporting large panes — perfect for contemporary homes, extensions and bi-fold configurations where maximum light and views are the priority.
