What Are The Features and Options of Skyview Polycarbonate Patio Covers?

  • Our unique 1¼” thick sheet with multi-layer construction provides the most insulation available. This amazing product filters out heat but lets in pleasing amounts of light.

  • Our 16mm (⅝”) triple skinned impact resistant sheet is available in clear, bronze and opal ice. These sheets block harmful UV rays and resist weathering while transmitting diffused natural sunlight.
  • Continuous lengths up to 24′ means that there are no purlins (cross members). Solariums with glass usually limit the glass panels to approximately 4′ lengths for structural and breakage reasons, but that results in several purlins, which are points where leakage can occur.
  • 10-year polycarbonate warranty, non-prorated covering: discoloration, loss of light transmission and loss of strength due to hail damage (up to ¾” size hail).
  • Available in White, Sand and Black Frame Colour.

  • Practical alternative to glass – weighs less, and the diffused light reduces heat build-up and glare.
  • High-strength ribbed design.

The shading coefficient is the ratio showing the amount of solar heat transmitted through the glazing. The lower the number, the less heat build-up you will have in your sunroom.

U-Factor (or U-Value) is the heat transfer rate from warm to cold areas in watts per square metre Kelvin (W/m2K). Lower numbers mean better insulation.

Typical insulated glass values:

  • single glazed glass, 5.91
  • double glazed with 13mm air space, 2.73
  • double glazed with 13mm air space & low e, 1.70
  • double glazed with 13mm air space, low e & argon, 1.36

Polycarbonate Patio Covers vs. Acrylic Patio Covers

Multi-wall polycarbonate sheets are known by these manufacturers or trade names: Polygal, Palram, Sunlite®, Lexan®, Makrolon®, Merlon®, Makrolux®, and Marlon, among others. Polycarbonate sheets are used extensively worldwide in greenhouses, roof glazing and daylighting applications.

The importance of polycarbonate’s high strength and impact resistance cannot be understated when considering snow capability, flexibility under load or falling items that can impact the sheet-like hail, sliding snow and ice.

Polycarbonate is also used in high-strength applications such as eyewear, bulletproof glass, headlamp lenses and industrial glazing. In all these applications, Polycarbonate sheets use a protective layer to prevent UV damage and ensure a long-lasting installation without discolouration. Multi-wall acrylic sheets are known by these manufacturers or trade names: Acrylite®, Cyro, Lucite®, Deglas®, and Plexiglas®, among others.

While known for their optical clarity, clear acrylic sheets are not a good choice for sunrooms or other low-slope applications like patio covers. Clear sheets let in too much heat and glare. Debris on a low-slope roof with glazing is less likely to be washed away by rain and is more visible with clear sheets.

Wise consumers will choose an opaque or otherwise tinted roof sheet for their patio covers or sunroom with light and UV filtering characteristics and, especially for sunrooms, a thicker multi-wall sheet with excellent insulation properties. Acrylic sheets are more economical than polycarbonate, more brittle and more flammable.

The video below shows the difference between polycarbonate and acrylic sheets in strength and flexibility. You decide which sheet is better for your next patio cover or sunroom roof project.

A Proper Structural Design

  • Skyview’s 4” high ‘I’ Beam Design. Never spaced more than 24” apart. Fully tested.
  • Snap Caps that hold down the glazing are not considered as a structural component.
  • Thermal break to reduce the chance of frost or condensation. Especially import for enclosed sunrooms.

Will It Hold The Snow?

  • This manufacturer says that extra capacity is gained by putting screws through the snap cap. But it’s a shape that will spread out under pressure. The cap can’t possibly stiffen the assembly in the presence of flexible ribbed rubber gaskets and a plastic glazing sheet.
  • An upside down ‘T’ bar is not a structural shape. The shape pictured is only 3” high. When designing the Skyview roof system, our designers ruled out the ‘T’ bar design as not having the capacity required to comply with building codes for common spans in most Canadian cities.
  • There is a thermal break cavity, but it is not used in this sample.

Patio Cover FAQ

Frequently Asked Questions for Patio Covers:

Q1 – What is a Patio Cover?

A1 – A patio cover is usually a lean-to roof system attached to the back of your house. The roof, columns, and beam need to be designed for your local snow load and your local building code. A patio cover is also referred to as a porch cover, veranda cover, or deck cover. On some homes, you could also attach your patio cover in a gable (a-frame) design.

Q2 – Are Craft-Bilt Patio Covers economical?

A2 – A cover for your patio is a fairly economical renovation. The most economical method is to use wood and shingles, but it won’t be maintenance-free. The next pricing level is our PanelCraft™ patio cover system which uses insulated aluminum panels. For a little bit more you can have our Northlander™ Skyview patio cover system which uses translucent sheets. These sheets allow pleasing amounts of light without the heat and glare of glass roofs.

If you plan it right, you can build an economical patio cover now, and in the future close it in with our 4 Track Windows, transforming it into a three-season room.

Q3 – What is Craft-Bilt’s Patio Cover’s warranty?

A3 – The aluminum members used in our PanelCraft™ and Northlander™ roof systems have a limited warranty of 20 years. Find more information on our warranty page.

Q4 – What are the best patio cover materials?

A4 – Aluminum of course! You want a patio cover that will stand up to the weather, won’t rot or corrode, and that you will never have to paint or re-shingle.

Q5 – Does a patio cover increase my property value?

A5 – We do not have any research data on this. But imagine yourself as a buyer looking at potential homes. Most of the homes you see will have a back deck, but when you see that patio cover you will start dreaming of all the wonderful times you will have in your new backyard. All things being equal, a house with a patio cover will outsell a house without one.

Q6 – How long does it take to install a Craft-Bilt patio cover?

A6 – Most patio covers installed by a professional will take one or two days. Please visit our installation instructions for more information.

Q7 – Will my patio cover be loud when it rains?

A7 – We have heard this question a few times. Light rain on your patio cover can sound romantic, but a really heavy rain might make conversation difficult. The sound of rain on a maintenance-free roof won’t be much different than a shingled roof, and it should not affect your decision to have a patio cover.

We can’t stop the rain, but we can stop it from landing on your patio 🙂

Q8 – Is a patio cover worth it?

A8 – A patio cover is sure to add value to your home. It extends the use of your deck and the amount of time you can spend on it. It protects your outdoor furniture year-round. It makes your backyard lifestyle better. Oh yeah, it’s worth it 🙂

Q9 – Can you walk on insulated patio covers?

A9 – PanelCraft™ insulated roof panels by Craft-Bilt are incredibly strong, and if installed correctly can easily bear a person’s weight. But this is not advised for a number of reasons: our unique Krystal Kote clear coating which is applied over the paint finish can make them slippery, if the panels are already laden with a large amount of snow, the added weight of a person’s “point load” could be dangerous and you could scratch the finish. Make sure to follow local guidelines for working at heights.

Working on a roof is dangerous, please use a professional.

Q10 – Can I walk on a polycarbonate patio cover?

A10 – Craft-Bilt’s Skyview Structural roof system is very strong. The large aluminum beams are spaced apart a maximum of 24 inches. It can bear the weight of a person but only on the beams. Never stand or apply any type of point load on the glazing.

If the roof is already laden with a large amount of snow, the added weight of a person’s “point load” could be dangerous and you could scratch the finish. Make sure to follow local guidelines for working at heights.

Working on a roof is dangerous, please use a professional.

Q11 – Do patio covers need footings?

A11 – A properly installed patio cover will have concrete pier footings designed to meet the local building code. Many contractors have moved away from concrete piers to steel helical piles.


Concrete Pier or Steel Helical Piles

Q12 – What is a good size covered patio?

A12 – Typical patio covers range from 10 feet x 10 feet to 12 feet x 20 feet. But all of our patio covers are custom made, projections can be as long as 18 feet, and widths can go to 40 feet or more.

Q13 – What tools are required for a patio cover?

A13 – Aside from the typical tools like drills, driver bits, hammer, level, ladder, etc., you will require specialized tools like a miter saw with carbide tipped blade for non-ferrous metal (also referred to as a blade for extruded aluminum), hammer drill, and heavy-duty snips.

You will need to install aluminum flashing where the roof meets the house, so if you do not own an aluminum brake you will have to arrange to get this flashing from a local siding shop.

For more on flashing, refer to our sunroom training course, ROOF CONNECTIONS – LESSON 9.

Your patio cover will need to resist wind and snow loads and meet local building codes, so a DIY project should not be taken lightly. Craft-Bilt deals with contractors across Canada that can supply and install your patio cover.

Q14 – How do I measure for a patio cover?

A14 – Your patio roof should always have an overhang. So if your deck is 12 feet x 12 feet, you would be best served with roof dimensions of 13 feet projection x 13 feet wide.

Typical heights at the front are seven or eight feet but can be as high as 12 feet. The mounting point at the house should allow for a minimum 1:12 pitch. For example, a deck with a ten-foot projection will have a drop of 10 inches (minimum).

Q15 – Why should I use polycarbonate instead of glass?


Glass Roof:

  • Solariums are Hot! Very expensive glazing is required to control the heat properly.
  • Sunlight can cause glare and fading of furniture and other contents.
  • Purlins are required (cross bars separating multiple pieces of glass), this is where many glass roofs will form a leak at some point.
  • If tempered glass breaks, it covers the floor with thousands of tiny pieces of glass, and the replacement glass is very expensive to replace both in labour and material.
  • There is a good chance of seal failure over the years and again, solarium glass replacement will cost a great deal in labour and replacement glass.

Polycarbonate Roof:

  • Excellent value.
  • The multiwall structure refracts the light, resulting in a pleasing light distribution with no glare.
  • Over 99% UV resistance. Almost the entire relevant UV spectrum, meaning both UVA and UVB.
  • The multiwall sheets are light, incredibly strong, and won’t shatter or crack like acrylic or glass.
  • Craft-Bilt polycarbonate sheets have a flame resistance rating of ASTM E 84 Class A
  • Skyview roofs by Craft-Bilt use one continuous sheet, there are no purlins, and no related leaks.
