Welcome to the World of Curve

It has come to our attention that a company which promotes the rigid style of insert is actively running down the curved solar insert and latest method of insert installation. We understand why they have taken this approach as there is a patent on the rigid insert (which like all inserts comes on a roll) and on their method of installation. However, regrettably we do feel it is necessary to make the following statement in order to provide a more balanced view of the latest method of installation so that you are able to make a more informed choice when choosing a supplier for your inserts.

The Problem

Polycarbonate is manufactured by extrusion. Extrusion by its very nature is not an exact science and there are typically small variations in flute size. Polycarbonate also expands and contracts with the heat and cold.

The Answer

A solution was needed and this came in the form of a flexible curved style insert. A curved insert profile makes allowances for the variations in flute width and also moves with the polycarbonate as it expands and contracts. With the curved insert maximum performance is achieved at all times, combine this with the latest sputter coated film and you have the premium solar insert.

In order to use the curved insert an installation method was needed that could install the curved inserts under slight pressure into the polycarbonate. This came in the form of the solar installation rod. The installation rod has proven to be a breakthrough with polycarbonate manufacturers and roofpack suppliers who recognised the benefits and rapidly adopted this method. Polycarbonate manufacturers including Brett Martin (one of the largest in Europe) and many others realised that the Installation rod saves them time and money. Installation is faster and less fiddly than before and the inserts are more effective as they expand and contract with the polycarbonate so compensating for any manufacturing irregularities.

Don’t be mislead by online videos into thinking that the rigid style of insert is simply quicker and easier to install.  Claims that the average size conservatory can be completed in just a few hours by your average householder are simply not true with either method of installation. In reality you need to allow yourself the best part of a day, from start to finish.

The curved style of Insert and the installation rod are used by the majority of the Trade in this industry.  Why is this?  It is because it’s more effective, allows for imperfections created in the extrusion process and moves with the polycarbonate, not to mention that it saves them time and money.
