Roof Substrate Layer

Fitted using a blowtorch the 3 layer felt roof system benefits from being more stable than the older methods.

Roof substrate layer.

The substrate under the membrane is either a cover board or the top layer of insulation. A sound stable substrate plywood offers excellent adhesion for conklin coatings. Mentioned previously as a roof decking plywood also can be used as a substrate over an existing roof. Layer that supports the remainder of the wall floor or roof.

Plywood panels bearing the american plywood association stamp are recommended and should meet minimum requirements of 15 32 exterior cc plugged or better. What are the different types of roof substrate available. One traditional single substrate layer extensive green roof was built for comparison with dual substrate layer green roofs. Suitable for a broad plant species diversity.

Provides insulation and prevents air penetration. Green roof substrate extensive is the substrate layer for extensive planting. Extensive green roofs are constructed of a substrate layer and a sedum plantation possibly supplemented with herbs and grasses. There are many different types available including options for green roofs and fsc sustainably sourced and produced types.

Sedum planting is exceptionally suitable for a roof because these plants can store a lot of water allowing them to cope with extended periods of drought. Roof substrates otherwise known as roof decking or rigid sarking support other roof elements such as vapour control layers insulation and roof finishes. Optigrün extensive multi layer substrate e heavy is used as a vegetation substrate for extensive green roofs with a multi layered build up for pitched roofs with roof pitch 5 and for roofs with high load capacity reserve. Fully adhered systems are bonded to the substrate using a contact adhesive applied to both the membrane and the substrate.

In construction a roof deck is also known as sheathing or substrate. Bauder ltd o duffy centre cross lane carrickmacross co monaghan t. The primary function of a deck is to act as a unifying structural diaphragm by tying all the components of a roof together. Material such as plywood or gypsum board which acts as a foundation for another material.

Fully adhered systems cost a premium and offer several advantages over their mechanically attached counterparts. 353 0 42 9692 333. Bauder ltd 70 landseer road ipswich ip3 0dh t. A roof deck is a roofing material layer installed on top of the rafters and right under the insulating layers of underlayment.

The substrates in dual substrate layer green roofs consist of an upper organic nutrition layer for plant growth and a lower inorganic adsorption layer for water retention and pollutant reduction. 44 0 1473 257671. The 3 layer felt roof system is also versatile when it comes to appearance.
