What is LEED?

The Philosophy of sustainability, LEED and Muskoka Granite veneer.

LEED stands for Leadership in Energy and Environmental Design and is a voluntary program to define and measure what constitutes a “green” building. Muskoka Granite veneer can play a role in attaining LEED certification by offering durability, reduced energy in the processing, as well as reduced engineering , labour and transportations costs since it is made right here in Ontario.
There are many benefits to using Muskoka Granite veneer from Ontario Stone Depot in LEED and “green” buildings, such as the efficient use of less stone with the material, the efficient use of structural components with the reduced weight (15 pounds per square foot), lack of volatile organic compounds or gasses emanating from the material, reduced energy for shipping and handling because it is a local product, the lack of environmentally damaging chemicals or materials in the extraction and production processes of the material and finally, the biggest benefit, which is the labour energy saving component achieved during installation.
Muskoka Granite veneer from Ontario Stone Depot is a very versatile and cost effective material to install and can be used to put new life into older, existing structures by going right over old brick or stucco buildings. There can be as much as a 45% reduction on labour/installation costs over full bed stone. The veneer product can be used in almost any application inside or outside and provides a superb alternative to manufactured stone, which is essentially processed concrete.

Muskoka Granite Veneer

We offer a large selection of Muskoka Granite Veneer products including square cut, five point, ledgerock, ashlar and a Muskoka Mix veneer. We are the only veneer manufacturer in Ontario that uses specialized guillotines and a TSX diamond blade saw.

Do not settle for hand cut imitations or granite that does not originate from the natural Muskoka outcrops.
With our Muskoka veneers you can place them right over existing structurers without needing a ledge. Your labour costs will be significantly less than a 4″ full bed stone.
Why settle for “fake”, non environmentally friendly veneer products when you can have Muskoka Granite veneer at an affordable price.


Check what our customers say about us

Greg and the team at Ontario Stone Depot were a pleasure to work with. They helped me pick a custom blend of stone that was exactly what I wanted. The stone from Ontario Stone Depot is a fabulous statement feature in our project
Heather Tulk
From start to finish, Greg and OSD have been great to work with. We purchased granite for two fireplaces, a firepit and large patio area, and steps from the house down to the lake. Greg arranged a tour of the facility and then followed up with a great product and timely delivery. We can highly recommend OSD for your Muskoka stone project.
