You have probably read and heard how prices for vegetables and other food essentials are going up and up. This could or may not justify the cost of a greenhouse; however as time passes, sooner or later the cost and quality of local vegetables may turn the tide.

Whatever the case, planning on a  polycarbonate greenhouse for the future should be on your list of things to do. Supporting the status quo year after year by paying higher prices for vegetables and other essentials may soon change.

In time, money saved today could provide the savings needed. Research the best way to get your very own greenhouse made with polycarbonate panels. Over the years,  polycarbonate panel sheets have become a widespread and popular way to glaze a greenhouse structure. For many years, we have always thought of greenhouses as being constructed with glass.

Glass has always been a form of construction best left up to professionals who build and handle glass, hence, which is why many backyards never had an aluminum and glass greenhouse. The cost factor for an aluminum structure and glass has for the most part been out of reach for many average homes and still is.

With the advent of low-cost aluminum, greenhouse kits, and easy-to-find polycarbonate sheets, greenhouse choices are easier to make. There is a slew of companies selling greenhouse kits today; making the right choice can often be difficult to choose. The durable and long-lasting qualities of polycarbonate are hugely popular.

Building a greenhouse with conventional lumber is becoming an affordable option, and if done correctly a wood-framed greenhouse can last for many years.

 Polycarbonate choices

Homeowners must consider the best ones to buy!

  • Durability, polycarbonate panels are virtually indestructible and not subject to easy breakage like glass, resist common accidents such as branch limbs falling, kids playing ball. etc etc…
  • Variety of shapes, profiles, thicknesses, lengths, widths, colors, and shades…Such as clear, grey, opal, and bronze
  • Versatility, not only can they be used for greenhouse structures but also for patio deck covers, trellis and arbor garden covers, skylights, pool, and spa enclosures, carports, partial sunroofs, foyer entryways
  • Lightweight, affordable and easy to work with, and virtually maintenance-free
  • Insulating values for temperature control and UV sunlight diffusion properties all of which help to stimulate plant growth.

Since there are so many choices, my opinion can only help to a degree. It’s important to make your own assessment.

Greenhouse structures should be built in accordance with the climate in your area. Some greenhouse kits will not hold up in areas such as high mountain regions, or in unusually cold frigid areas. Certain types of greenhouses should be built with your climate and weather patterns in mind. Make sure the kit purchased has a snow and wind load rating, some areas require certain building standards and when applying for a permit one must show a design and stamped engineering that supports local building codes.

If no permit is required then try to use your best judgment in accordance with the area in which you reside. You can find this information by calling your local building department. Then try to match up your building specifications with a manufacturer that offers kits or custom designs that will meet your criteria.

The best polycarbonate panels to use are the smooth twin, triple, and five wall panel types; they have insulating spaces for better heat retention and durability and are easier to install than the corrugated type normally found in local big box stores.

A word about single-ply corrugated polycarbonate, it certainly does get affected by hail, so do not let anybody say that corrugated polycarbonate is hail proof. Even twin wall polycarbonate can be affected by hail. A strong hail storm can even devastate a standard conventionally framed roof, let alone a thin sheet of polycarbonate. Despite this vulnerability, however,  polycarbonate triple wall and five wall panels are still the best choices for a transparent greenhouse roof.
