DO YOU HAVE AN ‘OLD’ CONSERVATORY OR ONE THAT DOES NOT PERFORM AS YOU WOULD WISH?
MANY PEOPLE FIND THEMSELVES IN THIS POSITION AND
THERE ARE OF COURSE NUMEROUS OPTIONS TO CONSIDER
REPLACEMENT:
It is important to make a fully objective decision if the existing structure and base are no longer fit for
purpose, have deteriorated structurally or the Sun Room is not of the size and style you wish to have
on your home.
Many people are successful in selling their existing buildings, even if they are of a very basic
structure. A competent DIY person may well be able to resurrect them or they could be used for a
basic plant room. Don’t consign them to a skip if there is a few hundred pounds you may be able to
put in your bank account together with saving the costs of demolition, removal and landfill.
NEW FRAME WORK AND GLAZING:
If your Sun Room is large enough and in the best position on your home together with
foundations and supporting walls which have withstood the passage of time, you may
consider a new framework and glazing. This will enable you to take advantage of the
latest glazing systems, using heat retentive and reflective glass, which can dramatically increase the
months of the year when you can comfortably enjoy ‘sitting in your garden’.
RE-GLAZING THE THERMAL AND HEAT REFLECTIVE QUALITY OF MODERN GLASS SEALED UNITS HAS
ADVANCED SUBSTANTIALLY IF YOUR CONSERVATORY WAS BUILT OVER 10 YEARS AGO. PROVIDING
THE MAIN FRAMEWORK IS SOUND, THIS MAY WELL BE A GOOD OPTION. IF HOWEVER YOUR
EXISTING ROOF IS LIGHTWEIGHT POLYCARBONATE, BEAR IN MIND THAT GLASS UNITS, EVEN FOR A
SMALL CONSERVATORY MAY WELL ADD HALF A TONNE THAT THE ROOF GLAZING BARS AND SIDE
ELEVATION NEED TO SUPPORT. IF THERE ARE NO TIE BARS, IT WOULD BE IMPORTANT TO
INTRODUCE THESE. SHOULD YOU WISH TO RE-GLAZE THE ROOF WITH POLYCARBONATE, THERE ARE
AN EXCEEDINGLY WIDE RANGE TO CHOOSE FROM BUT IT IS IMPORTANT TO DOUBLE CHECK THAT
THE EXISTING ROOF GLAZING BARS AND CAPPING SYSTEM WILL ACCOMMODATE THESE.
LEAD FLASHING:
Building and construction expectations have increased substantially. If the existing flashing where
your structure abuts the main building is not a high grade of lead or indeed cavity trays, it may well
be a good decision to upgrade this while the works are being carried out.
TILED ROOFS ONTO EXISTING STRUCTURES:
These are generally promoted when asking you if your conservatory is too hot in the ‘Summer and
cold in the winter’. This may sound like a sound proposition but there are important considerations
to make. The addition of a solid roof must come under Building Regulations, unless 75% of that area
is glass or translucent. Building Regulation Fees plus Structural Calculations, qualification of
foundation depths and lead cavity trays with all the issues and these roofs are usually many
thousands of pounds, together with a substantial amount of labour to install them. If this is an
option our are considering, it is very important that it is investigated fully and not least of all, you
should speak with your local Building Control Department.
TAKING ADVANTAGE OF YOUR EXISTING FOUNDATIONS AND SUPPORTING WALL:
Even if there has been no apparent movement or subsidence, should you contemplate constructing
onto these, it is essential that a professional and reliable assessment is made.
