I have used Ideal Combi on two projects and highly recommend them. The pricing is incredible, and the product quality is outstanding. Their customer service and installation deserve a 15/10. Faisil went above and beyond to ensure the ordering process, delivery, and installation were seamless. Val's attention to detail during the survey and installation was exceptional. I would use them again without hesitation and cannot recommend them enough!

In early 2023 we purchased triple glazed windows with powder-coated aluminium external frames and wooden internal frames for our house when we were retrofitting it to make it more thermally efficient. We have been delighted with the windows which look great and function brilliantly. They have helped to reduce our gas bill by 75%. The lead time from order to delivery is not quick and they are not a cheap option, but you get what you pay for and they were definitely worth the wait. We would definitely recommend Idealcombi.

After our previous window company going into administration Idealcombi stepped in to to expertly supply us with the high end slim frame thermally efficient windows we required for our new build. Michael Elliot, Luke Siggers and Damien Lee were most helpful and consistent throughout.

Thank you Idealcombi. I have Pureview doors and Futura+ windows put into my house extension and studio recently and am really pleased with your performance. The windows look great. With my new windows I can really feel the difference as my rooms feel much warmer. I have had no issues with condensation or draughts. Highly recommend your windows.
Where a stable door works best
Idealcombi outward opening entrance and stable doors are designed for direct access to the outside from spaces such as a utility room, hall or porch, where the outside area allows the door to open outwards. Because the door opens outwards, it can be especially helpful in rooms with minimal internal space where you do not want the leaf swinging into the room.
Typical reasons customers choose this style include controlling ventilation during cooking or laundry, keeping indoor spaces safer for children and pets, and improving comfort by introducing fresh air without leaving the home fully open.

Yes. The most common options are a stable door where the top section opens independently, or a fully glazed door that includes a ventilation function depending on the door type. Stable doors are specifically designed to let you open the top section for air while keeping the bottom closed for safety and control.
Sometimes, but it depends on the door construction, security needs, and glazing safety requirements. A door that is designed and manufactured with the correct glazing and hardware is usually the safer and more reliable route for external use.
They can be, especially when specified with modern insulated construction and modern glazing. Idealcombi publishes thermal performance figures for its outward opening entrance and stable door configurations, including double glazed and triple glazed options.
Yes, stable doors can be used as front doors, but it is important to choose a configuration with appropriate locks, glazing choice, and overall security specification for the exposure and risk level of the location.
