Have you considered the cost to heat and cool your sunroom or greenhouse? When deciding on the room that best suits your needs and budget - it's important to look at long term expenses, particularly operating costs and maintenance. Why pay more?

Most greenhouse manufacturers start with reasonably well-insulated designs, then assemble their units with metal screws or bolts. Each of these hundreds of fasteners conduct heat and cold right through the "so-called" thermally broke frame - costing you MORE MONEY! Moreover, if just a few of these fasteners are over-tightened or become loose with time ( freezing, thawing, wind, temp extremes ) stresses are created in the frame and glazing compromising its integrity and resulting in drafts or much worse.
