High quality windows and doors can only be made of high quality materials. Homerit chooses top quality materials from around the world for the fabrication of Homerit PVC-U windows and doors. The main materials for PVC-U windows and doors are PVC-U profiles, steel reinforcements, hardware, glass and timber jambliners.
For Homerit Premium Series PVC-U windows and doors PVC-U profiles are imported from VEKA ( www.veka.com ) Shanghai, China. VEKA has a worldwide reputation of producing quality products.

For Homerit Lifestyle Series ASA-PVC co-extruded color windows and doors ASA-PVC profiles are imported from Zhongcai Profiles Co. (www.zhongcai.com) – the first Chinese PVC-U profile manufacturer to develop color ASA-PVC co-extruded window profiles.
ASA-PVC co-extruded color window profiles
Developed in the 1970’s, ASA is acrylic-styrene-acryonitrile, a ternary polymer belonging to a group of shock-resistance modified SAN resins. ASA is a major product of GE Plastics which was under General Electric, now SABIC Innovative Plastics ( www.sabic-ip.com ), a world leader in providing plastic material solutions.
ASA material has great toughness and rigidity, good chemical resistance and thermal stability, outstanding resistance to weather, aging and yellowing, and high gloss. Because of this attribute ASA has been used heavily in the automotive industry, as well as several other outdoor applications.

All Homerit PVC-U window and door frame and sash profiles have galvanized steel reinforcements inside the central sealed chamber. All the steel reinforcements in our windows and doors are hot dipped galvanized to no less than 275g per square meter as specified by VEKA. This applies to the steel reinforcements for our Lifestyle ASA-PVC color profile system as well.
Not only are all Homerit PVC-U windows and doors reinforced by galvanized steel but also we have redesigned some reinforcements to make our windows and doors even stronger so that large size windows and doors can meet strength requirements under high wind load.
Hardware plays very important role in making sure the windows and doors operate smoothly for the years to come. There is suitable hardware available from top quality German suppliers such as Siegenia, Winkhaus, Maco, Roto and G.U. etc.
The diagram to the right shows sophisticated Siegenia multi point locking hardware for tilt and turn windows. The hardware is designed to take the weight of double or triple glazing and is three dimensionally adjustable. It guarantees the water and air tightness of the window and door. It also enhances security.
Homerit Premium Series PVC-U windows and doors are fitted with Siegenia and/or Roto hardware made in Germany. Both Siegenia and Roto hardware were tested to corrosion resistant Grade 4 (very high) of EN1670:1988.
Homerit Lifestyle Series ASA-PVC co-extruded tilt & turn windows and doors, tilt and sliding doors, bi-fold doors are also fitted with Siegenia and/or Roto hardware made in Germany. Awning windows are fitted with staineless steel hardware made in China, but customers can request German hardware.
Double glazing manufacturing can be done manually using very basic tools or done by high technology and high investment. The sealing around the edges is critical to make sure moisture would never get into the space inside the two glass panes. Fully automated double glazing manufacturing plant can produce high quality double glazing units that can meet EN1279 standard requirements. We use manufacturers which can make double glazing that meets EN1279 standard requirements.
Metro Glass is one of our business partners. Metro Glass provides quality glass products and services nationwide. All double glazing units come with 10 years performance warranty. Depending on where the building site is the glass will come from a local branch near to the building site.
In the early stage of our business we imported double glazing from China to reduce the cost. And we also manufactured our own double glazing units using basic equipment. These have proved to be problematic. Scratches and finger prints were found often because of the manual process. Some sealing failures occurred after several years and the double glazing units had to be replaced.
Standard Homerit PVC-U windows have got timber jambliners pre-fitted. Standard jambliners are finger jointed pine, H3.1 treated and pre-primed. Big size jambliners may be only H3.1 treated but not pre-primed.
Because Homerit PVC-U windows and doors can have jambliners pre-fitted. Installation can be done by builders and is very similar to the installation of typical aluminium windows and doors.
On request other types of timber such as Marcrocarpa can be used for jambliners instead of H3.1 treated pine at extra cost.
