From foundation to finish Pur Patio uses only quality framework materials to insure a durable patio
Framework materials: Making a choice!
FRAMEWORK MATERIAL QUALITY
Thanks to special agreements with its suppliers, Pur Patio receives only prime quality wood for its patio frameworks.
Premium quality lumber is less gnarled than lower quality grades and consequently more resistant.
The deck’s structure or framework
A durable patio framework must be designed and assembled to withstand the particular weather constraints found in Quebec.
A deck framework’s worst enemy: moisture
Our unique construction technique for wooden patio frameworks aims at eliminating water build-up in and around the patio framework.
Framework materials adapted to site and climate conditions
All beams are covered with a membrane to prevent infiltration between the components; all wood installed vertically is cut at a minimum 5° angle to allow water drainage and increase the durability of your wooden patio’s framework materials.
TREATED WOOD FOR A RESISTANT PATIO FRAMEWORK
TREATED WOOD FOR YOUR PATIO FRAMEWORK
Treated wood is usually sourced from local conifers like white spruce (Picea glauca), Engelmann spruce (Pice engelmannii), pine (Pinus contorta), and fir (Abies lasiocarpa). Since 2004, treated wood is no longer processed with chromated copper arsenate but with a much less toxic product called alkaline copper quaternary (ACQ).
The ACQ process allows the treated wood…
The ACQ process allows the treated wood to achieve a useful life of 25 years if it is installed properly and maintained periodically. However, the copper added to the treated lumber corrodes the assembly hardware such as screws, nails and brackets. Consequently, all assembly elements must be compatible with the ACQ process.
Pur Patio uses only premium quality treated lumber for its wooden patios. We check each structural element for twisting and crowning and pick only the finest pieces.
A good choice of structural material for your patio
FOR LONG SPANS UNDER THE DECK
MASSIVE AND WELCOMING STRUCTURES!
White pine and Douglas fir are large trees offering the possibility of creating massive and welcoming structures. These two types of wood may be used to create visible structural elements having a large span.
Pur Patio offers the opportunity to build a multi-level raised patio supported by oversized beams made of solid wood, presenting a design feature sure to add value to your yard. Also, it is possible to build a veranda featuring a visible white pine framework.
STEEL, FOR FEWER POSTS UNDER THE PATIO
STEEL PATIO STRUCTURAL MATERIALS!
Steel structures are heavy and difficult to handle, but to build a raised deck with the fewest possible supports (posts) and with a span exceeding 16 feet, steel is a logical choice. For a more environmentally friendly option, a recycled steel beam or post can easily be used.
QUALITY HARDWARE FOR YOUR PATIO!
ACQ APPROVED HARDWARE!
Given the presence of copper used in the treated wood process, all components used in the construction of a wooden patio must meet ACQ standards or better.
To ensure your deck’s durability, we only use the best mounting components: screws, nails, anchors, brackets, lag bolts, etc.
Your deck’s durability is very much dependent on the hardware supporting it. For more durability, we offer the «stainless option». Stainless steel offers the advantage of resistance to rust, thus avoiding drips along the components of your deck, pergola or fence. In addition, the stainless steel look is very fashionable and may be used as a design feature.
TO BE RESISTANT, YOUR PATIO'S FRAMEWORK MUST BE PROTECTED
In order to build a durable patio, particular attention must be paid to water accumulations and moisture. Remember that a wooden deck is subjected daily to the weather, and must withstand the yearly cycle of freezing and thawing.
WATER ON THE DECK MUST BE CHANNELLED
Channelling rainwater on the deck is essential to the patio’s longevity. No water infiltration should occur between the elements of a compound beam. Accordingly, Pur Patio uses a technique where all elements are protected by a waterproof membrane, a precaution often neglected by less conscientious wooden deck builders.
When installing the decking on your patio, our carpenters always use a calibrated installation template to insure constant and sufficient space between the boards. Spacing is very important to create the convection necessary for the natural evacuation of damp air from under the deck.
