How much light is there?

Up to 450+ watts in the 13" and 1200+ watts in the 21"

How is this different from a skylight?

There is a 3 Step Process: Collects, transmits and distributes light.  None of these things are performed by a skylight.

Back to Top

What about heat loss, heat gain and condensation?

Since the dome is sealed at the ceiling, air from the room does not mix with air in the mirror tube.  There is no condensation, and virtually no heat loss or gain.  Commonly used over showers as safe full spectrum light source.

Will it leak?

The SunScope™ was designed for Canada’s harsh climate and once properly installed it should be leak free.  The roof section (flashing) attaches in the same manner as a roof vent.

Maintenance?

The SunScope™ is intended to be maintenance free.  The silicone seals on the flashing should be inspected as recommended the same as any other roof attachments and flashings.  The dome and reflector are self cleaning.

What does the SunScoop do?

Increases light output in the room by up to 50%+ in winter months.  In Canada, the sun is low in the sky much of the year.  The SunScoop reflects low angle sun down the tube.  Without the large SunScoop the performance would be quite poor except in the summer.  .

Does the SunScoop and top dome catch snow or debris?

The dome allows everything to fall off it and the SunScoop is open at the bottom to allow most things to simply fall out.  By design the SunScoop clears itself.  Customers with heavy tree debris find nothing light blocking on dome.

Back to Top

Why is the interior dome not flat?

The shape of the high output diffuser dome is optimal for light dispersal in the room.  The deep dome allows for the entire room including the ceiling to be illuminated with full spectrum natural daylight.  A flat or nearly flat surface would act like a spotlight.  Don’t be fooled by some manufacturers photos.  Some show after photos which are impossible.

Does the interior dome have to be white?

It is almost transparent but does have enough white in it to allow the entire dome to light up and illuminate the room.  A clear dome would not light up the room.  Domes with prism patterns on them tend to be harsh.  The translucent dome provided has a spectacular pattern when illuminated by the sun.

What about UV (ultraviolet light)?

The acrylic blocks 99% of the UV so there will be no UV damage.

What makes the tube and Scoop so reflective?

The reflective surface can best be described as an electroplate or anodizing on top of the aluminum.  It cannot discolour, delaminate or blister.  It has nearly perfect reflectivity and CRI (colour Rendering Index).

Can the SunScope™ be installed on any slope roof.

Yes, the standard flashing works from a nearly flat 2/12 pitch to a 9/12 pitch.  There are also steep and flat roof flashing options available.  In all cases the tube comes straight up through the roof.  This is not the case with some competitors’ product.  Some competitors’ designs result in very poor performance.

Back to Top

Can the SunScope™ be placed on a non-south facing roof?

Yes, the combination of the tube being straight up, the SunScoop and the adjustable height, the SunScope™ can be installed on any roof face

Back to Top

Can the top of the tube be mounted higher to clear a roof peak or snow?

Yes, unlike competitors’ products the top dome generally sits high enough to be clear of most snow but if needed the tube can be extended up to 2'.

Back to Top

Will the extreme hot and cold or freezing and thawing cause any problems?

SunScopes™ are made entirely of metal except for the domes.  These materials have been proven over the years.  Freezing and thawing is not a concern since there is nowhere for moisture to enter the system.  The top dome attachment is designed to allow for motion of impact as well as freeze-thaw cycles.

Back to Top

Where is it made?

The SunScope™ is proudly designed and built in Edmonton, Alberta, Canada.           

Back to Top

What is the warranty?

The SunScope™ and all its parts are warranted for 10 years.

Back to Top

What holds the tubes together?

All SunScope™ tubes have a mechanical fit.  A silicone seal is applied to remove the possibility of dust entering.  Some manufacturers rely on a piece of tape to hold the tube, under force, together in your attic.

Back to Top

What if I have a vaulted ceiling?

Simple, you have 2 choices.  1) install the tube straight down, cut at an angle and install an oval ceiling dome.  This option gives you the most light.  or 2) install an elbow in the tube but not at the ceiling.  This option will reduce light output since there are more joins.  The elbow should never be located at the ceiling because light distribution will be effected significantly.  Light loss is minor for a single elbow.

Back to Top

Can I install it myself?

Yes, if you are comfortable working on the roof, in the attic and cutting the ceiling you should be fine.  Your dealer can help you out if needed and give you more advice.  Don't work on the roof or in the attic if the temperature is extremely high.  You and your roof will suffer.  Cold conditions are hazardous as well since shingles get brittle.  Winter installs can result in roof damage as well.  COMPLETE DIY kits from less than $200 CDN.

What is the difference between the Solarflair and the SunScope?

There are two basic designs in suntubes or tubular skylights.  Fixed pitch and variable pitch.  The Solarflair is a fixed pitch meaning it sits on the roof at a set angle and height.  Fixed pitch units are generally manufactured to go on a 6/12(rise of 6 over a run of 12) roof angle.  The SunScope is a variable pitch unit which allows it to always aim straight up regardless of roof angle and, the height of the tube can also be adjusted.  The Solarflair unit looks more appealing on the roof while the SunScope tends to perform better in a variety of situations.
