Food additive or carcinogen? The growing list of chemicals banned in EU but used in US, by Mikaela Conley, The Guardian, June 23, 2022
In an early study Jani et al. administred rutile TiO2 (500 nm) as a 0.1 ml of 2.5 % w/v suspension (12.5 mg/kg BW) to female Sprague Dawley rats, by oral gavage daily for 10 days and detected presence of particles in all the major gut associated lymphoid tissue as well as in distant organs such as the liver, spleen, lung and peritoneal tissue, but not in heart and kidney. The distribution and toxicity of nano- (25 nm, 80 nm) and submicron-sized (155 nm) TiO2 particles were evaluated in mice administered a large, single, oral dosing (5 g/kg BW) by gavage. In the animals that were sacrificed two weeks later, ICP-MS analysis showed that the particles were retained mainly in liver, spleen, kidney, and lung tissues, indicating that they can be transported to other tissues and organs after uptake by the gastrointestinal tract. Interestingly, although an extremely high dose was administrated, no acute toxicity was observed. In groups exposed to 80 nm and 155 nm particles, histopathological changes were observed in the liver, kidney and in the brain. The biochemical serum parameters also indicated liver, kidney and cardiovascular damage and were higher in mice treated with nano-sized (25 or 80 nm) TiO2 compared to submicron-sized (155 nm) TiO2. However, the main weaknesses of this study are the use of extremely high single dose and insufficient characterisation of the particles.
If you want to avoid titanium dioxide, Stoiber and Faber urge consumers to try and avoid processed foods as best as you can.
There are two primary forms of titanium dioxide commercially available: anatase and rutile. The rutile form is typically used in sunscreens due to its superior ability to handle UV rays and stability in the presence of UV light. The anatase form is typically used in other types of products, such as paint. Another plus of the rutile form is that its UVA protection extends past 400 nanometers, which is the upper limit of UVA.

The decline of the Roman Empire did not mark the end of terracotta usage. In fact, the material experienced a resurgence in the Middle Ages, impacting architectural styles throughout Europe. Many techniques and designs from the Roman era were revived and adapted, illustrating the lasting legacy of Roman innovations. Today, terracotta tiles continue to be popular in modern architecture, valued for their aesthetic appeal, thermal efficiency, and ecological sustainability.
Conclusion
On the other hand, traditional asphalt shingles typically come with a shorter lifespan, averaging around 15 to 25 years. This difference can lead to higher costs in the long run, as homeowners may need to replace traditional asphalt shingles more frequently. When considering a roofing investment, the longer lifespan of architectural shingles can prove more economical over time.
Factors Influencing Installation Costs

Conclusion
2. Ease of Installation 3 tab asphalt shingles are relatively easy to install, which can significantly reduce labor costs. Most roofing contractors are familiar with the installation process, allowing for a quicker turnaround time when replacing or installing a new roof.
5. Tile Shingles Commonly used in Mediterranean-style homes, tile shingles, typically made from clay or concrete, offer exceptional longevity and are highly resistant to fire. They are, however, heavy and may require additional support during installation.
In conclusion, adequate ventilation is essential for the optimal performance of clay tile roofs. Homeowners must prioritize installing an effective ventilation system that facilitates airflow throughout the attic space. By doing so, they can enjoy a cooler home, lower energy costs, and prolong the life of their roofing materials. Investing in proper roof ventilation is not only beneficial for the homeowners but also contributes to the overall sustainability of the building. Ultimately, effective ventilation is a cornerstone of maintaining the beauty and functionality of clay tile roofs.

This longevity is primarily due to the inherent strength of steel, which is resistant to warping, cracking, and curling. Additionally, steel roofs can withstand extreme weather conditions, including heavy rain, snow, and even hail. This durability makes them an appealing choice for homeowners living in areas prone to harsh climates.

Once all shingles are installed, it’s time to install the ridge cap. The ridge cap consists of shingles that are cut in half and placed over the peak of the roof. This not only provides a finished look but also prevents water from seeping through the ridge. Nail each ridge cap shingle in place securely, ensuring they are evenly spaced.
Understanding the lifespan of different types of roof shingles enables homeowners to make informed choices regarding their roofing materials. Investing in high-quality shingles and ensuring regular maintenance can result in significant savings over time, as it extends the roof's lifespan and delays the need for costly replacements.

One of the primary factors affecting the cost of dimensional shingles is the material composition. Dimensional shingles are usually made from asphalt, but the quality of the asphalt can vary. Higher-quality shingles that are designed to withstand severe weather conditions, resist algae growth, and offer better warranties tend to cost more. For instance, shingles with thicker layers provide improved durability and a longer lifespan, which can justify their higher cost over time.

The name 3-tab comes from the way they are manufactured. Each shingle has three cut sections that create the illusion of having three individual shingles when installed. This design not only enhances the aesthetic appeal of a roof but also allows for easy installation, making them a favorite choice among homeowners and roofing contractors alike.
Solid flat roofs are particularly advantageous in terms of insulation. Unlike glass roofs, which can allow heat to escape during winter and create a greenhouse effect in summer, a well-insulated solid flat roof conservatory maintains a more consistent temperature year-round. This means homeowners can comfortably use their conservatory regardless of the season. High-quality materials, coupled with effective insulation techniques, ensure that the conservatory remains warm in the winter and cool in the summer, ultimately increasing its usability and comfort.
Durability is another strong selling point. While traditional wood shingles may have a lifespan of 20 to 30 years, top-quality asphalt shingles can last 25 years or longer with proper maintenance. They are designed to withstand harsh weather conditions, including strong winds, rain, and snow. The weathered wood finish further enhances their resistance to UV rays, preventing the colors from fading over time.
After your felt roof tiles are fitted, routine maintenance is crucial for longevity. Regularly check for signs of wear, such as cracks or loose tiles, and address any issues immediately. Clean the roof periodically to remove debris and avoid blockages that can lead to water pooling.
In conclusion, metal clay tile roofs represent a synthesis of timeless beauty, remarkable durability, and modern energy efficiency. They cater to a diverse range of architectural styles while addressing contemporary environmental concerns. As building practices evolve, integrating aesthetic qualities with functional benefits becomes ever more critical, and metal clay tile roofs stand out as a compelling solution.
