Heavy hitting proposition
The Decalu88 bi-folding door and 6 lift-and-slide have been engineered
to deliver new design flexibility in aluminium, at a price point which maximises
margin for fabricators, according to Deceuninck Aluminium.
Aluminium bi-folding and inline sliding
doors were growing – in size, as well
as volume, before COVID- – and
despite the disruption lockdown has
caused to industry, commentators argue that
those trajectories remain fundamentally on the
“This is a simplified analysis but if you look
at where the markets for bi-folding and patios
were going before lockdown, three things were
happening,” says Nigel Headford, Deceuninck
Aluminium’s business development director.
“We were seeing significant market growth.
The market for aluminium bi-folding doors was
continuing to grow – as it has done consistently.
Volumes were lower, but the market for aluminium
inline sliding and lift-and-slide doors was also
growing – and price points were higher.
“And across those offerings, installations were
getting bigger,” he continues. “That has created
a demand for aluminium products which deliver
increased design flexibility, but at a price point that
remains accessible to the end-user.
“The Decalu88 bi-folding door and the
Decalu163 lift-and-slide have been designed to
support fabricators in hitting that ‘sweet spot’.”
The Decalu88 aluminium bi-fold delivers,
according to the Deceuninck Aluminium head,
a series of immediate advantages to fabricators.
It cuts manufacturing times by up to % over
comparable aluminium systems and in common
with the Decalu 6, features a single inner frame
and mid-section, plus integrated insulation.
‘U’ values are as low as .68W/m2k tripleglazed,
while co-extruded pre-inserted gasket with
rigid PVC-U backing eliminates manual insertion
of gasket and puts an end to gasket shrinkage.
But what it also does is to allow end-users,
installers and fabricators, to ‘go big’ with heavyduty
ultra-smooth-running systems able to
accommodate individual-sash weights, of up to
“Sash weight defines door size so the flexibility
to run to kg on each sash is a big advantage,
offering increased design flexibility. It will take you
to an individual sash size of around ,mm
by ,mm. In a run of, say, up to seven doors,
you can comfortably manufacture a bi-fold for
an opening of up to ,mm tall by ,mm
long,” says Nigel.
“That same design flexibility is also there in the
Decalu6 lift-and-slide door. It accommodates
individual sash weights of up to kg on a
single or double track option. That means you
can achieve an individual sash size of around
,mm by ,mm and comfortably
manufacture to an opening of up to ,mm tall
by ,mm long on a single run or m by m on
a twin track with just two sashes.”
The most recent report from AMA Research,
published at the beginning of this year before
COVID- hit, had predicted growth in the
bi-folding door market across sectors of % this
Its longer-term forecast, however, was also
positive, although it argues that growth may drop
to a still highly respectable % by the end of .
According to the authors of The Bi-fold Doors
Market Report – UK to , this would
mean, a total market value of £m by .
Aluminium remains the most popular material
type, with the majority of bi-folding doors
supplied, as expected, as replacements for older
inline sliding products.
It also highlights growth in demand for
aluminium inline sliding patio doors, which it
argues pre-lockdown, were increasingly being seen
by consumers as a ‘more exclusive’ alternative to
“The question now is, what has COVID
done/doing to these projections. The
conversations I’m having with retailers suggest
that demand is still very much there for both
inline sliding and bi-folding doors as still highly
aspirational purchases,” Nigel says.
Deceuninck Aluminium has also taken the
step to make both the Decalu88 and Decalu6
available as standard in a dual colour – and a
marine grade – finish.
“In retail now, during COVID-, consumers
want two things. They want to deal with a
company that will still be there in six-months’ time,
and they want design flexibility. That extends to
“What fabricators and installers decide to
do with it is up to them – but we aren’t charging
anymore for dual or textured colour and finishes
are marine-grade as standard,” says Nigel.
“That delivers opportunity to add margin, or
can tip the balance in your favour, allowing you to
offer product more competitively. Either way – you
get cash and cashflow back into your business,
which is something we all need to be doing.”
