Why PVC?

1. PVC windows are the Number One in energy efficiency

The frame of a window plays a decisive role in promoting energy and cost-efficient thermal insulation. Window profiles made of PVC score top marks when compared with aluminium or wooden windows. They have better insulation values and are able to reduce energy and heating costs. There is a particularly high energy saving potential when using PVC window frames in the passive house standard. Today, passive house windows can be manufactured efficiently and cost-effectively using state-of-the-art PVC profiles and the now quite common triple glazing.

2. PVC windows have a very good cost-benefit ratio 

PVC windows offer clear-cut cost advantages, both in procurement and throughout the entire life cycle. Timber frames are approximately 20-30 % more expensive than PVC profiles, and aluminum windows cost 30 % more again representing the most expensive alternative. Based on the high energy-saving potential and minimal maintenance throughout the entire service life of more than 50 years, costs are also saved in the long-term.

3. PVC windows are easy to care for

High quality PVC windows are extremely easy to care for and require minimal maintenance. Wooden windows, on the other hand, have to be glazed just about every two years and painted every 5 years. State-of-the-art PVC granule is extremely resistant to weather conditions and light-fast. To clean the window frames all you need is dishwashing liquid due to the easy-care properties of the smooth profile surfaces.

4. PVC windows are remarkably durable

As opposed to windows made of wood PVC windows have a particularly long service life. High
quality windows stand out with their distortion resistance and high level of functionality for years and years. Based on their long service live of at least 50 years PVC windows are an excellent investment, also with regard to maintaining a property’s value.

5. Rot Resistant

PVC does not rot and is resistant to corrosion.

6. Acoustic Insulation

Double glazed PVC windows and doors are able to cut down noise by as much as 70%.

7. Resistant to Salt Erosion

PVC is resistant to corrosion caused by salt-laden air making them ideal for coastal properties.

8. High Security

PVC windows incorporate multi-locking systems providing a high level of security for homes or businesses. Most uPVC window locking systems lock at multiple points all around the sash and frame.

9. PVC windows boast an excellent eco balance 

PVC windows are 100 % recyclable and therefore resource-saving. 40 % of all gas and oil reserves in the world are used for heating and for supplying energy to buildings, whereas just 4 % go into the production of plastics of which just 1 % are used for PVC. Besides being recyclable, the durability and low levels of pollution during the production of PVC profiles help produce an excellent eco-balance and contribute towards protection of the environment. PVC windows last much longer than wooden windows and consume substantially less energy during the manufacturing process.

Energy Efficiency

LEED, or Leadership in Energy and Environmental Design, is a green building certification used in the United States. Managed by the U.S. Green Building Council, this building rating system is completed by on-site or third-party verification. Many building types can apply for this certification program, including new construction, existing buildings, homes, and communities. LEED has four certification levels including, certified, silver, gold, and platinum. 

LEED has nine areas of focus, including location and transportation, sustainable sites, water efficiency, energy and atmosphere, material and resources, indoor environmental quality, innovation, regional priority, and integrative processes. The LEED certification program aims to have buildings use their resources more efficiently and create a safe environment for all its occupants throughout the building’s life cycle.

As of 2019, 80,000 projects were registered, with 32,500 projects having completed the certification process.
