Technical Information

Product drawings and technical information are available on the EBOSS website: eboss.co.nz

EBOSS is an online library for specifiers which hosts a range of product catalogues. The online technical manual includes product data sheets, installation drawings and sectional details for a range of configurations for each product. Profile sections are supplied in a range of drawing formats – PDF, DWF, DWG, DXF. Revit (RFA) details are available for most product ranges.

Detailed specification clauses for products are available on the Masterspec website (masterspec.co.nz) under APL Window Solutions.

Masterspec serves the New Zealand construction industry with a pre-formatted, up-to-date database of specification clauses, using an online interface to structure, edit, add support documentation and output to multiple formats. APL specifications are also available on Smartspec.co.nz

Note on R-Values and U-Values

Manufacturer Advice

Our manufacturers are in your local area and have a wealth of experience in meeting specifier design requests and queries on technical issues. Because of their involvement in manufacturing and installation on a daily basis, manufacturer advice is highly practical. Contact your local manufacturer through our websites: altherm.co.nz, firstwindows.co.nz or vantage.co.nz

In the Thermal Values section of each product page an R-value and U-value are assigned to that product, excluding glass. R-values refer to a material’s resistance to conductive heat flow, and a U-value is a related measure indicating material effectiveness as an insulator. The numbers outlined are indicative only and relate to a simple configuration of the product. Consult the APL Technical Department for more format-specific calculations, inclusive of glass. Another useful tool for calculating the thermal efficiency of a window or door configuration, inclusive of the glass chosen, is the Window Energy Efficiency Rating System (WEERS), which is a 6-star system assessing the thermal performance of the whole constructed unit. Our manufacturers or the APL Technical Department can provide WEERS calculations.

Span Tables

Span Tables outline the maximum length or span that profiles can be built to, and therefore the size of the relevant window or door.

Span Tables should be used as a guide for the suitability and compliance of the product. Span tables relate primarily to mullions, transoms and door stiles.

Span Tables for all products are available on EBOSS.

Three simple steps for using a Span Table

1. Select the centres of your product. Centres refers to glass width between mullions and stiles i.e. panel width e.g. 1500mm Centres as highlighted on the Span Table below

2. Select the column in the Span Table relating to the wind zone, the product will be located in e.g. Very high wind zone as highlighted on the Span Table below

3. Select the intersection on the Span Table where the centre and the wind zone meet. This will give you the maximum height you are able to achieve using this product e.g. 2245mm maximum height as highlighted on the Span Table below
