UPVC windows and doors

The material  most windows and doors made are made of is the cost effective and abundant UPVC.Unplasticised polyvinyl, or UPVC, is a rigid water-resistant plastic. UPVC neither decomposes nor warps it also does not rust like metal. Acids, fats, alcohol and salts cannot corrode UPVC this makes the plastic ideal to use in the production of drainpipes and downspouts, where mainly rainwater and natural organic residue flows through it.As and added bonus  UPVC is an excellent fire retardant material; this means that it has a hard time igniting and burning as a fire fuel.


UPVC panelled doors and its sections

 UPVC doors were first introduced to the market around 1985 and since then they have become the hottest sellers in the UK. Nowadays contemporary UPVC front and back doors can be seen on most homes. What makes them popular with homeowners is that they are lightweight, cheap, sleek, contemporary and contemporary looking. UPVC doors also come in a variety of colours, designs and wood grain finishes though the arctic white colored UPVC doors are the most popular.














Unreinforced UPVC panels

UPVC doors can either have glazed in glass windows panels or foam panels.

Most cheap UPVC doors have unreinforced foam panels. These cheap panels are made of two pieces of foam. Each polystyrene panel is only 24 mm thick! The outer UPVC coating is only 2mm thick. That’s correct a piece of polystyrene foam may be the only thing shielding your home from a burglary! Polystyrene is a good insulator but very weak when it comes to taking a kick. So weak in fact that an adult can kick through a piece of polystyrene door panel within 12 seconds!  This means that UPVC doors are not built to withstand brute force attacks.

Reinforced UPVC panels

UPVC door panels that have met quality standards are 28mm thick and have either a 6mm or a 9mm reinforced panel of wood glued to the foam panel. The wooden panel is either made of MDF, plywood or timber. The wooden panel is either glued between two pieces of polystyrene foam then covered by a UPVC coating which is at least 3 to 4 millimetres thick. Wooden panels protect the foam panels. The foam panel is placed behind and the wooden panel is placed in front just behind the UPVC coating. Burglars cannot cut and get through or blow torch their way through the wooden panel, so they are unable to reach weak foam panel.

UPVC Frames

Unlike composite doors, and all other doors, UPVC doors a built as a frame within a frame. A frame in frame is a door that is placed in a frame and then that frame is attached to another outer frame. The outer frame is connecting to the wall via the hinges. UPVC doors are not made of one solid piece; this gives them an extra week point. The inner door is easier to kick or ram through.
