4: Choose your insulated roof system

built up roof
Flat, pitched and curved roofs can be built with a built-up system, a sandwich or composite panel system or a structural insulated panel (SIPS).


A built-up roof system 

This uses a number of different components, all added to the roof separately to create the roof structure and insulation. Components could include insulation boards, membranes and waterproofing.
  • Most residential developments would use this approach which allows for insulation between joists/rafters of a pitched roof.
  • If your construction requires a flat roof, this approach allows you to create the fall in the roof structure itself or by using tapered insulation.
  • This approach also allows for flexibility in how you waterproof your flat roof – for example, do you choose an inverted roof which allows for waterproofing beneath the insulation board or a warm flat roof that requires waterproofing over the top?
Insulated panel roof

A sandwich or composite insulated panel system


Sandwich panels or composite panels are one completely integrated wall component with a steel top sheet, insulation foam in the middle and a steel inner sheet.

They are manufactured in individual panels to a specified length and are normally around 1m to 1.2m wide.

They attach directly to the steel frame of a building. To create the complete structure, you will also need structural steel frames, which we can provide.  
Kingspan SIPs

Structural Insulated Panels (SIPs)


SIPs can be used to create walls and roofs of a complete building.

They consist of a high performance insulation core that is autohesively bonded between two layers of OSB (oriented strand board)  during the manufacture process.

Building with SIPs often allows for a quicker construction and minimal site waste as the kit is designed and pre-cut before site delivery.

SIPs are also well suited to Passivhaus design as the excellent thermal performance can be supplemented and improved to meet the exacting standards required by the Passivhaus Standard.

5: Skylights & Rooflights

Skylight Domes
Once you have determined the type of roof (flat, pitched, curved) and roof system (sandwich panels, built up), it is time to explore effective daylighting products such as skylights and rooflights to integrate into your chosen roof system to provide natural light indoors.

There are a wide variety of options available including skylight domes, continuous rooflights and translucent roof panels to select from, and depending on the building and its daylighting requirements, Kingspan will have a product to meet your specific requirements.
 
For the product information see the tables further up this page

6: Smoke and Heat Ventilation

Smoke and Heat Ventilation
Another key consideration when creating or renovating a roof is smoke and heat ventilation which act to pump fresh air into the interior of any building, and to extract smoke in the event of a fire. An effective and optimised smoke and heat ventilation system will improve indoor comfort through providing fresh air while also maintaining an ambient temperature while also ensuring occupant safety. 

Kingspan provide a wide range of smoke and heat exhaust vents designed for roof installation including automatic opening vents (AOVs), vented skylights, louvred ventilators & flap ventilators, and can also design and install tailored systems to meet any building requirement. 

For the product information view the tables further up this page.
