For over and under purlin applications in Commercial and Industrial applications

SLE Cladding Ltd Notes.
Before the introduction of Composite Cladding, insulating roofs involved the use of white or foil faced insulation boards as featured below, plus lining panels, moisture barriers and other accessories together with large quantities of Tee bars, H Bars and Angle section plus a lot of labour.
Celotex Insulation Boards. Today Composite Cladding has resulted in a much reduced  demand for Celotex Insulation Boards, Tee & H Bars, etc, other than for repairs, such as after fire damage etc. SLE Cladding Ltd no longer carry stocks of Celotex White Faced or Foil Faced, Boards but we can still obtain them  to order, Mineral wool insulation is still stocked.
Tee Bars etc. Most former manufacturers have ceased production of these products, but SLE Cladding Ltd can still help. We can produce them in house in 3 metre lengths in Galv, White Polyester and Colorcoat Plastisol. CLICK HERE to go to our page on them for further details.
