Please note that many other manufacturers choose the smaller dimensioned 3” x 2” CLS (Canadian Lumber Standard), which is only 2.1/2”x 1.1/2”. As wood is a natural product, thicker means stronger, and therefore your building will last longer with a thicker frame.


We only use 16mm 5th-grade Scandinavian redwood, fully tanalised for longevity against fungal decay & insect attack.


Our standard offering is black Onduline with a minimum 15-degree pitch.

Alternatively, you may want an attractive felt shingle roof. Add a touch of originality price on application.

Ideal and Elite Range lined with 11mm OSB for additional strength and longevity. Lined Onduline roof also provides a cooler environment in the summer and warmth in the winter months.
