KNOW THE RIGHT QUESTIONS TO ASK! 1. Ask how many years the company been in business INSTALLING SUNROOMS. Many companies will tell you how long they have been building but the sunroom business is very different. 2. Ask for a list of "happy customers", and call them. Don't be shy! This is a significant investment - better to find out now if their customers were just "satisfied" or "delighted". 3. If the company is a dealer or franchise for a sunroom manufacturer, find out how long the manufacturer has been in business. 4. Is the company a member of the Better Business Bureau? Call or go online to the BBB and make an inquiry about the company. 5. How many styles of sunrooms are available? Beware of companies who have only a few selections of styles, they will be selling you their style instead of yours! 6. What type of warranty does the company offer? Remember the warranty is only good if the company is still in business. 7. Ask for copies of the company's insurance certificates. Are they current? 8. Does the company use tempered safety glass for your protection and not acrylic, "plastic" surfaces change color and scratch over time. 9. Compare glass qualities. Have the company produce an "R" value spec sheet like ours found on the last page of most of our catalogues. THE CHOICE OF GLASS IS THE NUMBER ONE FACTOR IN THE PRICE OF HEATING IN WINTER AND YOUR LEVEL OF COMFORT IN THE SUMMER. Wintergreen Solarium's use of CONSERVAGLASS PLUS ™ assures you that your sunroom will have the best glass in the industry and is only available through Four Seasons Solar Products. 10. How well does the glass control glare? 11. Does the glass control UV light to reduce fabric fading? Always ask the sales person to demonstrate how their glass performs. 12. Are the Sunroom's frames "thermally broken?" Thermally broken frames stop the transfer of heat to the outside and eliminate condensation and icing.
