We offer a range of gas flue boxes that are designed to be used in conjunction with the IL gas vent system. An IL gas flue box provides an economical and easily installed system that can accommodate a whole variety of domestic gas appliances. 

Our range of IL gas flue boxes includes two versions, recessed boxes, and freestanding boxes to suit your needs and requirements. The recessed version is deeper than the freestanding version which means that it can be fitted within the thickness of plaster, internal masonry, and timber stud wall if you’re after a flush appearance. 

We also supply a range of support plates in various sizes, including 125mm and 150mm.
