opening sizes

There are two formulae to calculate the opening size for Easifix:

 

Easifix panel with Easifix Sleeve and timber

 

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

 

Easifix panel without Easifix Sleeve and timber

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):

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: 791mmb) Minimun Opening Height:1364mm
