There are two formulae to calculate the opening size for Easifix:
Example one is to calculate the dimensions for the inside edge to opposite inside edge of the perimeter opening (including Easfix Sleeve & Timber framing):
Width | Height | |||
190mm glass block and 5mm joint | 195mm | 190mm glass block and 4mm joint | 194mm | |
Number of blocks a) x4 | 780mm | Number of blocks b) x3 | 582mm | |
Plus fifth joint | 6mm | Plus fifth joint | 6mm | |
a) Minimun Opening Width: | 786mm | b) Minimun Opening Height: | 588mm | |
---|---|---|---|---|
Easifix Sleeve x2 @ 17mm | 34mm | Easifix Sleeve x2 @ 17mm | 34mm | |
a+s) Minimun Opening Width: | 820mm | b+s) Minimun Opening Width: | 622mm |
If an Easifix panel is constructed into a timber stud wall and a clean line between the blocks and plasterboard is required, this can be achieved by omitting the Easifix sleeve and timber framing. However, re-calculate the opening size for just glass blocks and Easifix spacer, including perimeter expansion joint.
Example two is when Easifix Sleeve and timber have been taken out of the kit (excluding Easfix Sleeve & Timber framing):
Width | Height | |||
190mm glass block and 5mm joint | 195mm | 190mm glass block and 4mm joint | 194mm | |
Number of blocks a) x4 | 588mm | Number of blocks b) x7 | 1358mm | |
Plus fifth joint | 6mm | Plus eight joint | 6mm | |
a) Minimun Opening Width: | 791mm | b) Minimun Opening Height: | 1364mm |
