Providing a perforated underfelt, for example Type 3G, laid loose over the decking or over rigid insulation boards before applying the bitumen. Concrete is commonly found in roofs of flats and pre-war houses, providing stability and reliability as a deck material.
The heat-regulating effect keeps your building cool in summer and warm in winter – saving on your energy bills! You can also save money by doing some of the work yourself (for example removing and carrying off the gravel). We have five systems within our bituminous membrane portfolio – Bauder Total Roof System PLUS, Bauder Total Roof System, Bauderflex, Bauder Airtech, Bauder Stripes and one installation method (torch-free detailing). We remove any doubt or concern, by accepting the full liability for the design, material and quality of the installation workmanship on every Garland UK project.This is the start of many problems: leaks appear and other damages, which will increase if nothing is done. A polymeric layer should always be provided between the membrane and the ballast to protect the membrane from abrasion. The quantity of fleece to be used is simply calculated on the basis of the number of m² to be treated, to which must be added the edges on which it is brought up by a minimum of 10 cm / 4 inches. Modern mastic asphalt products incorporate polymer which enables an extremely durable and flexible material to be produced. The waiting time between coats is between 4 and 6 hours depending on the thickness and the ambient temperature.
Once this process commences it is critical to act fast to protect the structure and contents of the building. long story short I bought a house and garage roof was dire felt coming off and ply boards warped new roof to say the least leaking like a seive and if you stood in the garage u could see the sun through the roof really bad but didn't have the money at the time to spend on a new roof. If you are working in humid climates, and especially if it is cold after sunset such as in the fall or spring, be sure to finish the job a few hours before dark. This hybrid material combines asphalt membranes with polymerized rubber or plastic and is reinforced with fiberglass, creating a sturdy yet flexible roofing material.APP bitumen membranes are more commonly used on smaller residential projects in the UK, due to the forgiving nature of the systems and they are often an economical solution for flat roofing applications. The difference is that SBS bitumen (Styrene-Butadiene-Styrene) is provided with a protective top coat, as opposed to APP bitumen. Reinforced with RD-Roof Fleece, the new membrane will be durable and highly resistant to different weather conditions including UV rays, rain, hail, snow, hot, cold, etc. Installation of flat roofs has undergone significant advancements in recent years, resulting in improved durability and maintenance. Prior to and after any work carried out on or in the vicinity of the flat roof, conduct thorough inspections.
Felt Roofing (also known as roll roofing and Bitumen Flat Roofing) refers to the use of roofing felt to underlay other building materials, such as bitumen or asphalt, separating the roof covering from the deck, allowing water to run off and providing an extra layer of protection from damaging weather. Explore our range of case studies that highlight challenges and solutions of past projects and discover how our approach and systems have achieved high quality, guaranteed roof tops on both new build and refurbishment sites. Single-ply membranes can be laid as one entire piece with the eaves and verge already formed in the factory or in rolls which are laid in strips. Formulated with a high percentage of SBS modifiers, StressPly Signature allows for easy application thanks to its low-melt properties and extreme cold bending flexibility, down to temperatures as low as -30°C; making this membrane suitable for the most demanding of environments. High Tensile Strength: Mod bit is celebrated for its resistance to punctures and tears usually resulting from storm damage, wind-driven debris, and foot traffic.APP is plastic and more rigid than SBS, it has a higher melting point meaning that it has a higher temperature tolerance than SBS during gas torch application, making it a little more forgiving during installation and particularly suited to warmer climates. If the existing deck consists of close boarded tongued and grooved timber with a minimum thickness of 18mm, it is advisable to use exterior grade WBP 6mm plywood as an overlay.
Bitumen appears as a sticky black substance that is predominantly used for paving, roads and as a flat roofing membrane and waterproofing. Bituminous roofing systems can be used for green roof build ups with a root resistant cap sheet which stops the roots from penetrating the waterproofing system. Felt roofing consists of many layers to provide optimum waterproofing whilst remaining breathable and looking good. Formulated with SBS modifiers, StressPly Evolution benefits from enhanced thermal, mechanical and anti-aging characteristics, giving the multi-layered system excellent tensile strength, tear and puncture resistance and elongation properties. At the same time, they need to protect against degradation from continuous exposure to the elements.If you require advice before you purchase, visit our Colour Showroom in Brierley Hill, DY5 1UT where we will advise on the best products and colour combinations to meet your requirements. The system uses BauderPLANT E when a green roof is specified to form the Bauder Total Green Roof System (BTGRS). A minimum of 10°C / 50°F and no rain expected during and immediately after application are required to apply products comfortably. Elastodeck can be used on most types of mineral surfaces and is easy to use with a roof fleece to seal these more fragile areas. Consequently, the shrinkage- and expansion tension in the roof construction and roof seal will be lower.
