With a range including sliding, single and french doors, you can bring life to any property with the full WarmCore set.
Designed specifically to offer superior thermal performance in the aluminium market, WarmCore beats all its competitors with U-values as low as 1.0.
WarmCore windows and doors come with a 10-year guarantee as standard so you know your products will stand the test of time.
Practical living spaces
WarmCore folding sliding doors come in a range of configurations to ensure the final product meets the everyday needs of homeowners in cold, mild and Mediterranean weather.
WarmCore has been designed from the ground up by the experts at Synseal Group and is the epitome of precision British engineering.
At the heart of WarmCore products is a thermal core which significantly out-performs the polyamide thermal breaks commonly used in other aluminium systems. The fully concealed, bright orange, multi-chambered core maximises the use of lower conductivity material to improve thermal performance by up to 25%.
WarmCore Bi-Fold Doors
The innovative design of WarmCore folding sliding doors enables you to split the door sashes in whichever way suits your home. You can have all the sashes fold to the right or left, or have them split in any combination you choose. A popular configuration is to have a single door at one end, called a traffic door.
This flexibility enables you to use your WarmCore folding sliding doors in a way that suits you, rather than being forced to fully open them every time. Leave that until you're entertaining or when the day is so good it deserves to be let in. This allows you to leave the majority of the door sashes locked in place, using a single door for everyday use. In addition certain door configurations offer even more practicality, as the door sashes that meet in the middle, or at one end, can be used as a set of French doors - when you don't need, or want, the doors fully open.
WarmCore French Doors
The WarmCore system is also available as French doors, ideal for keeping a consistent look with a larger set of WarmCore doors. Built to the same exacting standards as the larger doors, this range gives you all the benefits of Warm Aluminium, at a more modest size. Openings that are 2 door sashes wide can still be specified as folding sliding if you prefer, with the door sashes folding to the left or right as required. With WarmCore it's your choice.
WarmCore Residential Doors
The WarmCore system is also available as single residential doors, ideal for keeping a consistent look with a larger set of WarmCore doors. Built to the same exacting standards as the larger doors, the residential door gives you all the benefits of Warm Aluminium, at a more modest size.
