During an earlier period in my life, I lived in a house that had a glass conservatory. It was one of the things I liked best about the house. I would spend hours lounging on the sofa with a book in my hand gazing out into the garden. I used it throughout the Spring and Autumn and even during the hot summer months of the year.
People often complain about heat build-up in their conservatory, but my conservatory had a unique feature, it had the ability to raise the ridge, (the highest part) of the roof, to let the hot air out. Warm air rises and in a conservatory it gets trapped. My conservatory got over this problem by releasing all that hot air and sucking in cooler air through the windows and doors at the bottom.
Now that conservatory must have cost someone many thousands of pounds when it was first put in and most conservatories are nothing like it. That ability to raise the ridge was a game changer. Most conservatories installed in the late 20th Century were modular (supplied in set
Universal Edge Trim or Aluminium F section? Which is best for a rafter supported roof?
Both of these sections are used to create an end bar at the right and left edges of your rafter supported roof.
The powder coated aluminium one is obviously more expensive than its PVC cousin. Your choice should however, not be based purely on cost as each section has its own merits and is better used with specific glazing bars.
The Universal Edge Trim or PVC F section
This universal edge trim was created specifically as a trim for PVC capped rafter bars which are used with polycarbonate sheeting. Designed to fill the outside of the bar to easily create an end bar. The two prongs on the underside of the section replace the gasket in the outside of the glazing bars, clipping into the place where it would have been. It is not designed to be used on its own as it has no structural strength and will not be effective against wind uplift. This trim will balance up the bar and create a neat waterproof finish.
PVC capped bars are a cheaper option than aluminium screw down ones. Does that mean they are low quality? Not at all!
By far our best selling rafter glazing bar is our PVC capped snap down one. The bar offers a great combination of being neat, easy to fit, and very good value for money. This bar is suitable for polycarbonate sheets but not for glass. We also have a range of aluminium capped rafter bars which are suitable for glass.
The bar is easily adapted from an intermediate bar (one that joins between two sheets) and an end bar. To create your end bar, simply click in a universal edge trim (PVC F section) this will balance up the outside of the bar and neatly cloak off the edge of your roof.
We offer three PVC capped bars as part of our range:
