This porch conversion in Lucan is another great example of a design choice that fits with this semi-detached home. This upgrade - from a dated aluminium glass porch with poor insulation and security values to a brick-built porch with Palladio Composite Doors and internally-glazed triple glazed 70mm rehau uPVC windows, offers ultimate security and insulation.
We insulated the existing canopy attic space in this build.  As a rule, these structures do not have insulation as they are outside the main house area. After this, we dry-lined all walls, completed a plaster finish, tiled the floor, and finished with low-energy down-lights as is standard with all our porch extensions and conversions. Again, this is a small investment for big savings.

Windows are, again, triple glazed in black on white 70mm, Rehau sections for security- which comes with the choice of double or triple glazed units up to 40mm in thickness.
