1. Fantastic Thermal Performance

Aluminium windows, bi-folding doors and roof lanterns all offer brilliant levels of thermal efficiency, making them hugely popular with owners of both modern and traditional homes, as well as anyone adding an extension and hoping to improve on the current energy efficiency of their home.

Choosing high quality aluminium roof lanterns or bi-folds will ensure excellent U-Values and ensure your home doesn’t suffer from heat loss or overheating.

2. Super Slim Sightlines

When installing expanses of glazing, one of the main objectives is usually to maximise views of the great outdoors. Aluminium roof glazing and bi-fold doors can be manufactured with incredibly narrow sightlines meaning no chunky frames, fixings or joints to contend with. They can also be supplied in a huge number of configurations and sizes — the Korniche roof lantern can span up to 3m x 2.5m for a single piece of glass per side, or up to a maximum roof space of 6m x 4m with intermediate rafters.

3. Easy Installation

If you were thinking installing a roof lantern would be convoluted, disruptive and take a long time then think again. New technology at the top of the market has meant simple, swift fitting is now possible — in fact, some are designed to be fitted in a matter of minutes. Roof lanterns from Korniche, are so simple to fit that they can be installed by a competent DIYer.

4. Superior Security Levels

When installing new bi-folding doors, security is naturally something considered by homeowners keen to ensure the safety of their homes is maintained. Aluminium bi-fold doors offer fantastic security levels — providing you choose a high quality product. Look out for bi-folds with 3-Star YALE locking barrels and high strength shoot bolts with anti-back drive locking handles.

5. Low Maintenance

Forget annual repainting or the need for fiddly routine repairs — aluminium bi-fold doors and roof lanterns require nothing more than a quick wipe down now and again.
