Why good quality windows and doors matter

In addition to loadshedding, the increase in cost of living is affecting South Africans, necessitating changes in purchasing trends and products traditionally chosen for building projects, to maximise benefits from modern products for modern buildings, to save energy, and reduce peak demand.

Rehau’s uPVC window and door system is one of the products that need to be looked at more closely.

Energy efficiency

Rehau recently undertook a performance modelling exercise with Solid Green Consulting to evaluate and demonstrate the energy efficiency of Rehau’s uPVC windows/doors, as energy efficiency is becoming one of the main points when selecting products for new build or refurbishment projects.

The performance study took various climate conditions, thermal comfort and light conditions in Cape Town, Johannesburg and Durban into consideration. Thermal comfort, solar heat gain, and temperature losses through the building envelope were modelled and calculated.

The performance modelling exercise showed excellent result for lower energy consumption of the modelled building when using Rehau fenestration systems, either single- or double-glazed, compared to single-glazed standard metal windows.

Installing Rehau uPVC windows and doors will greatly assist with the reduction in annual energy consumption from heating or cooling a home.

Durability

The uPVC profiles are made using a special recipe to ensure that the windows and doors are suitable for the climatic conditions in South Africa and are UV stable.

This ensures that Rehau’s quality window and door profiles are hardwearing and durable, with some of the installations done countrywide about 30 years ago still in good condition and effective.

Rehau’s warranty on uPVC profiles is 10 years, which is a best-in-class of all window systems in South Africa, where very few alternative systems offer a warranty of this length.

Noise reduction

Fitted with single- or double-glazing, uPVC windows and doors offer a noise reduction of up to 38dB. This is an important benefit for homeowners staying close to busy highways, shopping malls, airports, or in dense housing developments.

Low maintenance

uPVC profiles supplied by Rehau are low maintenance as they don’t need to be treated or maintained to keep them working effectively and looking good.

Housing developments, free-standing homes, commercial buildings

The benefits mentioned make Rehau uPVC windows and doors the preferred choice for a variety of buildings. They have been specified for developments such as Northgate Heights, Groot Parys Lifestyle Estate, 22 on North, etc. Hotels such as the Fairlawns Boutique Hotel, Aviator Hotel, Holiday Inn Sunnyside Park, and The Cape Milner Hotel have chosen Rehau uPVC systems for their advantages.
