Professional, Insurance Backed Installation


Strength, Slim Sight Lines and More Glass


Aluminium is a very strong material and as a result can support more weight. When manufacturing products such as Bi-folds using aluminium the frame can be made thinner yet still have the strength needed to support the glass and other components. Slimmer frames means more glass, and more glass means more light is able to pass through it, creating a brighter living space.


Environmentally Friendly


Aluminium is an environmentally friendly material too. Recycling aluminium saves up to 95% of the energy needed to produce it from raw materials. And even when recycled continuously aluminium does not lose any of its quality or performance benefits.


Low Maintenance Material that Lasts


Through manufacturing, installation, and the rest of its lifetime, aluminium is a very low-maintenance material. It will not warp, rust or need painting, and it doesn’t suffer from expansion problems in heat or cold.


Thermal Efficiency & Highly Weathertight


Contrary to beliefs that aluminium is a ‘cold’ material and therefore does not insulate well, aluminium can actually be more thermally efficient than some PVCu systems. Bi-fold Network aluminium Bi-folds feature a thermal break that helps keep the cold from transferring from the outside of the frame to the inside. Combine this with high-specification energy efficient glass and you have a high performance door that will help keep a room warm and comfortable.
