We Are Proud of Our Doors.

Over a century ago, we set out to make doors that homeowners would be proud to call their own. But before we could do that, the doors had to first exceed our expectations. Today, that pride takes many forms, from our total commitment to safety to our reputation as pioneers of new products to creating doors with the quality our customers have depended on for decades. And that pride also takes shape in our commitment to natural resources and our environment.

Our Environmental Policy

The Simpson Family of Companies have a long, proud history of research and innovation. We have been pioneers in sustainable forestry and were early and enthusiastic supporters of the Sustainable Forestry Initiative® (SFI®). Simpson affiliates have earned high praise for their groundbreaking habitat conservation plans for protecting fish and wildlife and were the first private landowners in the country to successfully develop and implement a plan for the Northern Spotted Owl in California.

These works are based on some fundamental principles that make up our environmental policy:

  • Foster a beyond-compliance philosophy in our business such that operations achieve or exceed all applicable environmental laws and regulations.
  • Make environmental considerations a priority in operating existing facilities and planning new ones.
  • Minimize effects on the environment and work to continuously improve environmental performance through practices such as pollution prevention and resource conservation.
  • Educate our employees on their responsibilities for environmental compliance and management.
  • Our fiber and wood purchasing practices foster sustainable forest management and the wise use of America’s most abundant renewable resource.
  • Regularly review and update our environmental performance and management systems.


We’re honored to work with such a resource as wood. An extraordinary building material, no alternative comes close to its abilities to conserve energy and address global climate change. Further, wood is naturally renewable as the resource is continually growing. Net annual growth for the nation’s commercial forests exceeds harvests and losses to insects and disease by an impressive 50 percent each year.

Our Daily Commitment

Nature gives us an incredible resource to work with and we are conscientious to manufacture a product that is efficient, avoids waste and diminishes pollutants.

We purchase raw lumber and door components from responsible and reliable suppliers that subscribe to sound forest management practices, many of which are certified by a third party. We can also make doors with virtually unlimited choices of wood species.


辛普森门没有添加尿素 - 甲醛(Nauf),这最大限度地减少了潜在的污染物并提高了室内空气质量。此外,辛普森门是CARB(加州空气资源板)2阶段兼容,并已收到四星级认证来自日本土地,基础设施和交通部,是第一个需要VOC测试的国际机构之一。

Wood advantages:

  • No other commonly used building material requires as little energy to produce as wood.
  • Wood is resistant to heat, frost, corrosion and pollution.
  • Using wood products reduces the need to burn fossil fuels for concrete and steel-based products, which reduces the amount of greenhouse gases released into the atmosphere.
  • Wood removes pollutants from the air, rather than emitting them, sequestering greenhouse gases.
  • 木材是一种有效的绝缘体,因为其蜂窝结构包含限制其传导热量的空气口袋。

Our Work Continues

We are strong supporters of third-party certification and green building programs. Their efforts have elevated home and building product design and development. And as the parameters of these programs are fine-tuned over time, we applaud those that include a lifecycle assessment as part of their evaluation.
