What is the Best Material

for Roof Light dome ...?

Okay, let us understand what is called a “ DOME ” at first,

Dome is a shape , a shape which is hemisphere or semi sphere. It seems by using the words hemisphere or semi sphere here, that the base has to be circle. True to an extent but in today’s nomenclature, The Dome refers to an elevated surface from centre of the base having different radii ending at base . And base can be circular, square, oval or at times even triangle.

Now let us understand the term “Roof light"

Simplest explaination can be like…..

“ Sunlight passing / transmitting through any type of roof, full roof or part of roof, bringing brightness beneath the roof can be called rooflight”

Selection of Material for any product, depends on end use of the product / application of product.

To manufacture or make ROOF LIGHT DOMES, It is evident that the materials’ MUST characteristics needs to be……

Allowing Sunrays to pass through.
Withstanding UV Sunrays for long life.
Moldable to desired shape so that fits well and no leakages occure from it.
Light weight so that can be lifted and installed on roof or roof can be made from it.
Low maintenance.
Repairable

Market uses several types of materials to make ROOF LIGHT DOMES

Fibreglass Reinforced Plastics ( FRP)
Glass / Toughened Glass
Acrylic sheets
PVC sheets
Polycarbonate Sheets

Now Lets evaluate the material to make ROOF LIGHT DOME out of it.

Based on desired end results , expected life span & budget One can select ROOF LIGHT DOME material and its products.

So considering the above factual table points, It is evident that best

ROOF LIGHT DOME material is POLYCARBONATE SOLID & MULTIWALL SHEETS

FULL ROOF LIGHT DOMES USING POLYCARBONATE SOLID & MULTIWALL SHEETS

Requires MS structure to install sheets onto it.
MS structure shape is shape of ROOF
Joinary at every width of sheets.
Aluminium sections & EPDM gaskets required to
install the sheets.
Small to Extra Large Sizes and Numerous Shapes
possible.
Monolithic Shapes not possible.

SMALL ROOF LIGHT DOME with POLYCARBONATE SOLID SHEETS

Requires Vaccum forming Technology production set up.

Sheets take shape of mould, So desired shape requires
mould.
Being monolithic leakage is not an issue.
Size Ranges : 150mm x 150mm to 2000mm x 2000mm
Shapes : Pyramid, Round dome, Square Dome
Multiple pieces can be used with MS Structure to cover
larger areas and enhance aesthetics.
Sandwiching possible to minimise heat transfer.

Got Questions?

Which is the best material for Large ROOF LIGHT DOME ?

Polycarbonate Multiwall & Solid sheet is the best material for ROOF LIGHT DOME, considering its flexibiity, Toughness and Formability.

What are the shapes possible for ROOF LIGHT DOME ?

Three shapes namely a) Round Dome b) Square Dome 3) Pyramid

Polycarbonate domes become yellow in shorter time ?

Yes, only when the non standard / non thermoformable / non uv coated sheets are used to make domes from it. Otherwise on hand experience teaches us that for 10 years , no yellowing happens.
