Korniche Roof Lantern

Self cleaning glass combines both self cleaning and solar control properties, making them highly desirable amongst homeowners looking for the ultimate in glass solutions. The coating that is applied to the glass breaks down organic dirt and by doing so reduces the adhesion of inorganic dirt. Water droplets are spread out to form a sheet and this picks up the loosened dirt particles as it drains off the surface. The result is remarkable and a difference you can actually see.

Thermal transmittance, also known as U-value, is the rate of transfer of heat through the glass. It is measured as watts per square meter Kelvin or W/m²K. The better the insulation, the lower the U-value is.

Aluminium like all metals is a conductor of heat. If our profiles weren’t thermally broken the inside heat would be wicked away and lost to the colder outside. By creating a profile assembled with polyamide sections between the inside and outside portions, the ‘thermal bridge’ is stopped. Polyamide is a glass filled plastic meaning it is an insulator and therefore there is virtually no conduction of heat through it.

Powder coating provides better performance than wet paint—it is more resistant to chipping, scratching, and other wear because of the thermal bonding it undergoes during curing, and because it can be applied in much thicker layers. This performance is especially important for outdoor products, like aluminium glazed products.

In addition to its physical toughness, powder coating provides superior colour retention. Long term exposure to moisture, sunlight, and heat breaks down the resins found in both paint and powder coating. This process, known as chalking, causes resin and pigment particles to lose adhesion. Affected particles form a chalk-like layer on the coating surface.

The early stages of chalking merely give the coating a faded appearance, but severe chalking will eventually erode the coating enough to compromise surface protection. The rate of chalking depends on the resiliency of the resin. Polyester based powder coatings are frequently used as topcoats due to their exceptional chalk resistance.

By investing in a door that meets the UKAS PAS 24 2016 security regulations, you can rest assured that you are installing a safe and secure door into your property. The certification means that the door you are purchasing has been tried, tested and approved by the professionals, and can be considered secure enough to use for your home.

Although you can’t buy the products directly from ourselves as we are business to business only, you can use our ‘geo tool’ to source a local suppler to buy from. Alternatively, we can sell directly to your builder.

The Korniche lantern is a product that most people could competently undertake the installation of. It requires no specialist tools and everything goes together only one way. The Korniche bifolding door however, is a little bit more specialist and we recommend that a tradesperson with fitting experience of glazed products is used to ensure the best installation and performance is achieved.

Our patented clip bead is used on our bifolding doors to retain the glass units in the sashes. The traditional method of retaining glass in aluminium glazed products is to locate an aluminium bead profile and pre load it with the use of a wedge gasket. Essentially there is enough room to locate the bead profile in the sash and then a wedge gasket is fitted to take up the gap and means the bead cant be removed. This is time consuming and fiddly and the result isn’t always as consistent in terms of appearance as some might hope. The patented clip bead we developed has a pre fitted gasket and utilises a plastic clip element that enables the bead to be clipped in incredibly easily and quickly. The result is not only neat and the sightlines consistent but also saves your installer a large amount of fitting time.

Q-Lon seals offer the ultimate in material and function to provide the highest standard of sealing ability, even under extreme conditions. As they have a foam core, they offer excellent memory and return to their original shape even after periods of long compression and due to the polyethylene film and polypropylene insert, they provide fantastic sealing performance and don’t stretch or shrink over time.
