The Designer Door Company is a premium product-focused window installation company based in Ballyhackamore, Belfast. Every day we install uPVC and aluminium double glazed windows to customers across Northern Ireland. Whether you own a period property, barn conversion or modern home, we offer a wide range of frame styles and colours to suit any homeowner’s personal tastes.
A double glazed unit is a window consisting of two panes of glass which is separated by a layer of trapped argon gas. The argon gas has a high percentage of thermal conductivity of air, which makes it a poor conductor of heat, and this improves energy efficiency because it keeps the warm air inside the property. The second pane of glass also strengthens the windows to improve security and helps keep your home free of outside noise because the extra pane of glass also acts as a secondary barrier to noise.
Each Designer Door Company high-quality, double glazed window comes with a WER ‘A’ Rating as standard. They are designed for enhanced energy and thermal performance, and the multi-chamber design minimises heat loss through the frame. For maximum thermal efficiency, the Soft Coat glass, warm edge spacer bars and high-performance glazing reflects internal heat back into the home whilst absorbing solar energy from outside.
We offer many beautiful styles of window frames like bay windows, sash windows, casement windows, shaped windows, tilt and turn, and French windows, so when choosing a company to help with your home improvement needs, choose Designer Door Company.
