Windows & Doors — Supply and Installation

Windows and doors from Showcase Plastics in Maldon, Essex – uPVC, aluminium and composite options for homes, extensions and replacements, with supply or professional installation.

This category covers window and door systems and related hardware from our base at Unit 6, Heybridge Industrial Estate, The Causeway, Maldon CM9 4XL. Use it when you are replacing tired frames, opening up a rear elevation, or upgrading security and thermal performance.

What you’ll find in windows & doors:
uPVC windows – energy-efficient casements and related systems from trusted ranges such as Liniar, including multi-chamber profiles suited to everyday domestic work.

Aluminium windows — slimline and prestige aluminium ranges for a sharper contemporary look.
Aluminium doors – heritage, prestige and designer-style aluminium door ranges for front and rear openings.
Composite doors – high-security, energy-efficient front and back doors (including premium ranges such as Solidor where supplied).
Bi-fold doors – aluminium and uPVC bi-folds to open living spaces to the garden.
Sliding doors and stable doors – patio and stable-style options where the opening suits.
Aluspace system – internal doors and screens for open-plan layouts.
Hardware and spares – handles, replacement locks & keys, window hinges, cills and frame extenders.

Glazing options: Windows can be specified with single, double or triple glazing as the system allows. For misted or blown units in frames that are still sound, see glazing & replacement glass and our glass replacement service – often cheaper than full frame replacement.

When to choose new windows or doors
Frames that are warped, failed or beyond economical repair
Poor insulation, draughts or outdated single glazing
Security upgrades (especially composite front doors)
Opening up a room with bi-fold or sliding doors
Matching a new extension to existing openings
