powder coating. Once cooled, a topcoat is also spray-applied
with a measured minimum paint thickness at 140 microns
on the finished frame. Being able to control this key stage
of production ensures consistency across all rooflights that
leave our studio.
giving every rooflight an authentic handcrafted character.
No two are ever exactly alike, a subtle detail that reflects the
handcrafted nature and skill of the individual person behind
each rooflight. Finally, each rooflight is passed through the
independently verified quality control system to ISO 9001,
ensuring the highest levels of manufacturing quality.
Glazing
Natural Evolution
To maintain exacting standards and BSI Kitemark status,
our insulated glazing units (IGUs) are manufactured entirely
in-house. Initially, the glass is washed, dried and inspected
to ensure it’s blemish-free. The aluminium spacer bar
separating the glass panes is half-filled with desiccant and
fitted to the primary seals and inner and outer glazing. This
creates a cavity, which is 90 percent filled with argon gas.
There are two types of edge seal used, structural silicone
for contemporary applications and hot melt for heritage. A
standard insulated glazing unit can be produced in just eight
minutes.
Our commitment to manufacturing in the UK is why we are
proud to be recognised as a member of the Made in Britain
community, joining a network of businesses that share our
belief in the value of British-made products.
As demand grows for authentic heritage solutions and
thoughtfully designed natural light within architecture, The
Rooflight Co. continues to lead the sector it helped create
30 years ago. Combining British craftsmanship, technical
expertise and a passion for quality, we remain proud
originators of The Conservation Rooflight which continues
to be trusted by architects, appreciated by conservation and
planning officers while still handcrafted in Britain today.
Gathered for Assembly
All the elements are now ready for the rooflight to be
assembled. Vacuum lifting equipment is used to safely
handle the large glazing units. Once the thermal barrier has
been bonded to the frame, the IGU is lowered and bonded
into place. A weather seal is applied before the final qualitycontrol is carried out with nothing, but perfection accepted.

Finishing Touches
It is the finishing details that make the greatest difference,
especially in our Conservation Collection. The glazing bars
replicate the appearance of traditional Victorian rooflights
while avoiding unnecessary heat loss. Each silicone seal is
hand-finished to recreate the look of classic putty glazing,
