ü LFC is cementatious material integrated with mechanically entrained foam in the mortar slurry which can produce a variety of densities ranging from 400 to 1600 kg/m3. The application of LFC has been primarily as a filler material in construction works. In order to develop thermal property model, LFC is treated as a porous material and the effects of radiant heat transfer within the pores are included. ü Extensive compression and bending tests at elevated temperatures were performed for ...
The building system uses pre-cast Ferro cement roofing channels of a segmental arch profile which are placed adjacent to each other and spanning. over two supports. After partly filling the valley between channels with concrete, the channels form an idealized T-beam and are able to carry the load. of a roof / floor.

Used together, Siplast SBS-modiﬁed bitumen roof membranes and Siplast Lightweight Insulating Concrete Systems result in a longer lasting roof. And, since Siplast Lightweight Insulating Concrete Systems are reroofable, signiﬁcant cost savings over the life of the building can be realized.
Foamed concrete is also much lighter than slopes made from mortar screeds. This means that a roof with a slope made of foamed concrete has a lower loading on the structure of the building. Properties of Foamed Concrete used for Roofing Typically the foamed concrete is made with dry densities of between ~ 400 and ~ 600 kg/m3.
Foamed Concrete Screeds. The high air content of foamed concrete screeds make them ideal for use as floor and roof screeding materials where the lightweight nature of the materials reduce deadloading on the structure whilst achieving outstanding excellent thermal efficiency. The material can be laid to fall at thicknesses from 50mm to 1000mm in any one application, can be easily pumped, laid and finished.

FAQ: Should My Concrete Tile Roof Be Installed Using Foam or ...
Mar 28, 2019 · When it comes to the installation of concrete roof tiles, the level of wind exposure a home or commercial project is subjected to will determine what fastening methods should be used. If your certified roofing contractor has presented you with the option of choosing either mechanical fasteners or foam, then the choice is ultimately yours! […]
The roof finish is standing seam metal attached to the structural concrete roof formed by the Lite Deck® system. Notes from the Architect: The Muldraugh, KY SAFE room project we finished using lite deck is performing much better than expected.
Foam Roofs are Lightweight, Durable, and Seamless. The Dura-Foam Roof System has a rigid and durable surface that you can walk on. A thick (typically 1.5″ thick) closed-cell polyurethane waterproofing barrier seals the roof against leaks. Spray Polyurethane Foam (SPF) is the only roofing material that has no seams.
Basic Information of Roof & Its Functional Requirements
The roof is used to protect the house from all type of weather. A Roof must be strong to withstand snow and wind load. The basic object of the house or home is to provide shelter. The roof is the uppermost portion of the building. In roof construction, a roof is covered by covering materials which are supported on a structural member.
A concrete roof is exactly what it sounds like: a solid slab of concrete capping the top of your house. Exact specifications vary, but most concrete roofs are several inches thick. For example, the Florida-based company Hurricane Proof Systems offers a 7-inch (18-centimeter) slab of concrete in three layers.

A. Vermiculite Concrete — 6 cu ft of Vermiculite Aggregate* to 94 lbs. of Portland cement and 0.06 to 0.5 lb. of air entraining agent. Min thickness of slurry coat (vermiculite concrete topping thickness as measured from top of steel roof deck to bottom of foam ed plastic) shall be as shown in the following table.
When foam concrete is caste in-suit, as in the case of roof insulation, care should be taken to see that the ensuing shrinkage is taken care of. While hairline cracks are normal in the case of roof insulation, limiting the depth if depth of casting and allowing a setting an interval between consecutive casts ensures quality of set foam.
Jul 26, 2013 · The Concrete and Clay Roof Tile Installation Manual gives guidance on two attachment methods for hip and ridge tiles: mortar-set or attachment to a ridge board. Based on post-disaster ﬁeld investigations, use of a ridge board is recommended. For attachment of the board, refer to Table 21 in the Addendum to the Concrete and Clay Roof Tile
How to Install Rigid Foam On Top of Roof Sheathing ...
Apr 03, 2015 · If you end up with R-20 foam or R-24 foam instead of R-49 foam, your roof won't rot. You'll just have higher energy bills than a house with code-minimum insulation. On a hip roof, there isn't much point in spend extra for ventilation channels above the rigid foam, since soffit-to-ridge venting is impossible on a hip roof.
