Style meets energy efficiency.

Rylock has been designing and specifying products that consider Australia’s diverse landscape and local climatic conditions for more than 35 years. It has always been an essential component of everything we do.

Energy Efficient building design considers the specific climatic conditions of a given site. Climate and orientation are variables that can add comfort and value to your home. Window and glass door product type and size are critical factors in this process. Appropriate glazing for winter heat gain, carefully positioned products to encourage cross-ventilation and opening clerestory windows to vent warm summer air are but a few design examples.

The NatHERS (Nationwide House Energy Rating Scheme) provides homes with a star rating out of ten based on an estimate of potential energy use (heating and cooling) and in many states and territories a 6-star rating is a minimum requirement.

Double Glazing

INSULATION THROUGH GLASS

An IGU (Insulated Glass Unit) is made up of two panes of glass that are separated via a perimeter spacer to minimise heat transfer between the inner and outer panes. IGUs in Rylock products use an inert gas – argon – for greater thermal performance.

Double glazing is the most cost-effective way to minimise heat transfer through windows and glazed doors and can be even more effective when they feature high performing glass within the IGU.

Air Leakage

MINIMISE SUMMER HEAT GAIN

Air leakage – or ‘air infiltration’ – refers to how well a product seals the inside from the out. Rylock products typically feature at least two seals on every opening element. Most products are glazed with inner and outer seals to prevent drafts and glass rattling.

Four-point compression locks on Rylock hinged doors compress the seal properly. Our bar operated awnings and casement windows are designed with secondary latches to seal shut effectively. Best practice installation techniques should also be adopted to ensure air leakage is minimised around the perimeter of every product.

Solar Control Glazing

EFFECTIVE PRODUCT SEALS

Solar Control glazing helps limit the amount of heat gain via radiation through the glass. This is best suited to climates where cooling requirements are predominant, or aspects of a building that are unprotected from summer heat.

The term used to describe the performance attributes of such glass is SHGC (Solar Heat Gain Co-efficient), which is the fraction of solar radiation transferred through a product. A ‘Low e’ (low emissivity) coating helps reduce the SHGC, whilst body tints or spectrally-selective glazings are a more traditional method of achieving this reduction in heat transfer.

Frame Conductivity

MINIMISE heAT TRANSFER

The frame conductivity of a window is important in determining how quickly heat transfers from where it is hot, to where it is not. Naturally, this cycle changes through the seasons however this measure is always made through the U-value.

Rylock products are thermally modelled during the design phase to minimise heat transfer through conductivity, whilst enjoying the strength and durability of a quality powder coated aluminium window system. Our Thermally Broken Series of windows and doors deliver the ultimate performance, whereby an insulator separates the inner and outer extrusions.
