    Solar Heat Gain:
    We’ve all had the experience of parking our car at the mall on
    a sunny day, then returning to the car an hour later to find that it’s an oven inside.  
    Sunrooms are glass-intensive structures which make them susceptible to overheating. 
    Up to 90% of the surface area of a sunroom is glass, so the performance of the glass
    has a direct and significant affect on the comfort and usabilityof the room. 
    What sense does it make for your clients to invest in sunrooms or patio rooms that
    overheat so quickly that they can only be used comfortably on mild days in Spring or Fall?

    sunroomsSmart Glass 60 & 90 is Cooler in Summer/Warmer in Winter
    4 times Less Heat gain & Heat Loss

    4 times more insulation than our closest competitor’s glass

    Keeps your heating & cooling bills lower. Allows you to use your Room year-round
    Prevents fading of furniture with 5-times less ultraviolet destruction

    Ultraviolet Radiation: It is widely know that UV radiation is harmful and damaging, to
    people as well as to fabrics and furnishings.  Glass products that transmit a high percentage of UV radiation will result in faster fading & damage to fabrics & furnishings in that room.  Homeowners who spend time in these rooms receive unsafe exposure to harmful UV radiation


Wall Materials

  Vinyl Composite Construction

                Our vinyl composite construction as used in the Omega series room is unique to the sunroom and patio room industry.   Aluminum, which is commonly used in other manufacturer’s sunrooms and patio rooms is among the worst construction materials for energy efficiency.  Aluminum conducts both heat and cold very rapidly!

               In contrast, Vinyl is among one of the most energy efficient building materials;  1400 times less conductive to heat and cold than aluminum, which means the vinyl room will be warmer in winter and cooler in summer than the inside of a room constructed from aluminum.  Equally important, The frame components in C-Thru vinyl windows and doors contain numerous insulating pockets which helps increase the performance of our Omega room over traditional low-end patio rooms fabricated from aluminum.  These insulating pockets also significantly reduce the transmission of outside noises into a C-Thru Omega sunroom, which in turn improves the ambiance and usability of the room.

sunrooms Comes Standard on All Rooms
Tuff-Core is made of expanded polystyrene, the same material used in freezer walls, refrigerators, coolers, etc. The energy conserved in heating and cooling quickly pays for itself. To compare its insulating capabilities to other materials, 3" of Tuff-Core is equivalent to:
  • 8" of fiberglass
  • 15" of hardwood
  • 72" of brick
The outer Tuff-Core "skin" is as strong as it is beautiful and is:
  • Maintenance Free
  • Flexible and Durable
  • Molsture Resistant
  • Scatch and Ding Resistant
    - It's nearly indestructible!

Tuff-Core is standard for our Curved and straight Eave roofs,
and optional for the solid wall area.

Even a screwdriver can't scratch the paint off -
because the color is impregnated into the material

       Unlike low-end aluminum doors and windows used in other sunrooms and patio rooms, C-Thru’s Vinyl windows and doors utilize a welded construction.  All of the headers and jambs are solidly welded into a strong one-piece frame.  This one-piece welded vinyl frame will not come loose or separate like low-end aluminum windows and doors, which are made from four separate headers and jambs held together with screws.

             In coastal applications, the salt in the air will corrode the hardware in your competitor's aluminum windows and doors, making the operation of aluminum doors and windows difficult over time.  Our Omega windows and doors contain no such hardware, therefore they are perfect for coastal applications.

   The superior insulation properties of Tuff-Core used in all C-Thru room walls means superior energy savings for you. sunrooms

             C-Thru’s unique vinyl composite patio rooms, with our welded vinyl construction, also have a much cleaner and refined look than aluminum rooms since they do not require near the amount of screws and hardware typically associated with typical aluminum construction.  The cleaner look and higher efficiency of C-Thru’s vinyl sunrooms and patio rooms means that your client’s projects will look as good 10 years from now as the day they were built.  That translates to better energy efficiency and a higher quality look now, and more resale value later.

Cardinal Insulating Glass with patented XL Edge Thermal Spacer

           Insulating glass units supplied by C-Thru are manufactured in Cardinal IG’s highly automated state-of-the-art factory, and utilize Cardinal’s unique and patented XL Edge thermal steel spacer around the perimeter edge of the glass units.  Since 1978 Cardinal has produced insulating glass units manufactured with a unique dual-seal system.  This system uses a polyisobutylene (PIB) primary seal and a silicone secondary seal.  PIB is the best material for keeping moisture out and argon in, and silicone is the ideal material to long-term structural integrity for the sealed glass unit.  Units manufactured with this dual-seal system have demonstrated a failure rate of less than 1% after 20 years in the field.  Based on decades of real-time experience in the field and in the brutal P1 lab test, where glass units are subjected to high temperature and humidity cycling while undergoing unusually high exposure to concentrated UV rays; PIB/Silicone dual-seal silicone systems last 4 to 10 times longer than other types of sealing systems insulating glass. 


6063-T6 Aluminum posesses all of the characteristics required to build the high quality C-Thru Sunrooms. But a unique vinyl cladding system (called a thermalbarrier) placed on the inside and outside of each structural member eliminates the one negative attribute of aluminum - heat and cold transfer.

The Structural Thermal Barrier provides:

  • 9 times more thermal value
  • 7 times less likely to condensate
  • Dramatically reduces the transfer of heat and cold while maintaining the great benefits of an aluminum structure
  • Fewer exposed fasteners

Double Cam Window Lock

          In these days of rising crime and home break-ins, security is a very important concern to your clients.  At C-Thru we understand that, and have designed a locking system that takes a back seat to no one.  , C-Thru uses a cam lock In our Omega product line Instead of latch-locks like our competitors use, which can become unlatched if the sliding panels of the windows are jarred by an intruder.  Cam locks work better than any other type of locking mechanism because once the cam lock is engaged, it stays engaged.  But C-Thru doesn’t stop there.  Instead of using a single cam lock, C-Thru installs dual cam locks on it’s windows.  Two locking mechanisms for double the security.  Your clients might want to ask themselves a question  …  why aren’t other manufacturers as concerned about security as C-Thru?
