WINDOWS AND DOORS
WHEN IT COMES TO
WINDOWS AND DOORS,
QUALITY MATTERS
The increase in the cost of living experienced worldwide has naturally affected South
Africa, which also bears the expense of load shedding. This necessitates changes in
purchasing trends and products traditionally chosen for local building projects in order
to maximise benefits and save both energy and reduce peak demand. Rehau’s uPVC
window and door systems are products that offer these benefits…
ENERGY EFFICIENCY AND REDUCTION OF
ENERGY CONSUMPTION AND PEAK DEMAND
Rehau recently undertook a performance modelling exercise
with Solid Green Consulting to evaluate and demonstrate
the energy efficiency of Rehau’s uPVC windows and doors,
as energy efficiency is highly important when selecting
products for new build or refurbishment building projects.
The performance study took various climate conditions,
thermal comfort and light conditions into consideration
across areas like Cape Town, Johannesburg and Durban.
Thermal comfort, solar heat gain and temperature losses
through the building envelope were modelled and calculated.
The performance modelling exercise showed excellent
results for lower energy consumption in the modelled
building when using Rehau fenestration systems – either
single or double glazed – compared to single glazed
standard metal windows.
Installing Rehau uPVC windows and doors will greatly
assist with the reduction in annual energy consumed from
heating and cooling a home.
DURABILITY AND LONGEVITY
The uPVC profiles are made using a special recipe to ensure
that the windows and doors are suitable for the climatic
conditions in South Africa, and are UV stable.
This ensures that Rehau’s high-quality window and
door profiles are hardwearing and durable. Some of the
installations done countrywide about 30 years ago are
still effective and in good condition.
Rehau offers a best in class 10-year warranty on uPVC
window and door profiles, with very few local alternative
systems offering a warranty of this length.
NOISE REDUCTION
Fitted with single or double glazing, uPVC windows
and doors offer noise reduction of up to 38dB. This is
an important benefit for homeowners staying close to
busy highways, shopping malls, airports or in dense
housing developments.
LOW MAINTENANCE
uPVC profiles supplied by Rehau are low in maintenance
requirements as they don’t need to be treated or maintained
to keep them working effectively and looking good. They
only require a wipe down to remove the dust build-up.
The benefits mentioned make Rehau uPVC windows
and doors the preferred choice for all kinds of buildings.
They have been specified for various developments such
as Northgate Heights, Groot Parys Lifestyle Estate, 22 on
North, and hotels such as the Fairlawns Boutique Hotel,
Aviator Hotel, Holiday Inn Sunnyside Park, and the Cape
Milner Hotel have chosen Rehau uPVC systems for their
many advantages.
