Window, door and conservatory FAQs
The other common cause of this fault is contamination of the weld by failing to peel back the protective tapes from the profile cut edges prior to welding.
Although it is common practice not to do this, it is obvious that the tape melts back with the profile and contaminates the finished weld when the machine closes the joint. Indeed, the requirement for the tape to be peeled back is contained in the BPF Guidelines for welding.
On the subject of patio doors, we are often asked if the sliders must be in the centre of three and four-pane door assemblies. In fact you can put the sliders wherever you like, in the middle or at either end. If the meeting style supplied in the kit is used as a coupler between the fixed panes, then the cutting constants remain the same.
Cavity Closers FAQs
A cavity closer is a critical building component that seals cavities around wall openings and provides a rigid template for bricklaying, and window or door installation.
· Provide a damp-proof course (DPC)
· Provide a thermal break
· Prevent damage from condensation
· Reduce heat loss and CO2 emissions
The cavity closer acts as a seal, preventing water vapour and damp from entering the cavity wall and the building, whilst also preventing heat loss through the gap. They can be used in a range of different construction types, including masonry, timber frame and steel frame systems.
