Working with Clint to build a greenhouse dome kit was so much easier than trying to figure it out from plans I found on the web. Clint knows his stuff.

What is Keder?

Perhaps you have heard of PolyKeder™ or you have read about keder, however you are just not so sure what the stuff is!

Keder is the name of a type of beading or cord that manufacturers place along the edge of thin sheeting of a material, allowing for it to be attached to a structure. In many cases keder is used to attach vinyl signs to rigid structures facilitating a secure attachment.

The German manufacturer of Polydress® LPKeder, RKW SE, has implemented this concept into a greenhouse film designed for the purposes of providing a way to attach and secure the covering to a greenhouse frame. By attaching a keder bead to a greenhouse film, many advantages unfold to the greenhouse owner.

RKW created their keder bead out of a very durable polyethylene which allows an easy heat weld to occur to the plastic sheeting, which is a Multi layer bubble sandwich also made of high quality polyethylene. The keder bead is welded to both sides of a roll of polyethylene and the resulting product is referred to as Polydress® LPKeder aka SolaWrap™ .

The rolls of Polydress® LPKeder aka SolaWrap™ greenhouse plastic come in widths of 4 ft., 5 ft., 6 ft., and 2 meters. These widths are specifically designed to the support normal bow spacing that occurs in commercial greenhouses, as well as, backyard greenhouses and hoop style greenhouses.

The keder bead, is secured to both sides of a roll of polyethylene bubble film, that allows for easy assembly. The keder bead is then guided through a profile connector piece, referred to as high impact PVC extrusion. This piece of specially engineered plastic is like a tracking system that securely locks the polyethylene plastic covering into place, enabling continuous connection of the greenhouse plastic while connecting it to each of the bows of a greenhouse.

This ingenious system creates an airtight, watertight attachment of the plastic covering to the roof of a greenhouse. Unlike the placement of normal 6-mil polyethylene that stretches across the whole greenhouse structure causing uneven weight bearing of the end walls, SolaWarp evenly distributes wind load and snow load across each bow of the greenhouse. This system allows precious plants to be protected from the elements and will require less greenhouse maintenance for years to come.

So, in other words, you will spend less money and less time replacing your greenhouse covering, which is a common requirement for greenhouse structures, commercial, backyard or hobby greenhouses. An additional benefit here is environmentally, as greenhouse fill does not break down so there is less greenhouse plastic to dispose of.

There have been reported cases of winds in excess to 130 mph that ripped off the 6 mil double blown covering enclosing greenhouses, cracked or removed polycarbonate panels. However, the greenhouses covered in SolaWrap™ remained unscathed. The honeycomb design creates superior strength in the face of dynamic forces such as wind and hail. Attach a keder bead and it is nearly impossible to rip panels of SolaWrap  off of a greenhouse structure.

Purchasing a geodesic dome greenhouse kit encompassed with SolaWrap™ plastic covering will ensure that you will have protection from harsh weather conditions for generations to come. For more information contact us at 1-781-816-7811 or
