frequently asked questions

  • What is the difference between Western Red Cedar and Meranti Timbers?
  • The Botanica timber series features a unified design and size range and is available in either cedar or meranti. Botanica is constructed from engineered timber to minimise the effects of sun and moisture on the product over time and both cedar and meranti are sustainably sourced, with a traceable chain of custody.


    Why choose Cedar?

    Western Red Cedar is renowned for its natural beauty and colour variation. It works well indoors and outdoors, and achieves any look from natural and rustic to clean and contemporary. It also resists warping, cupping, twisting, rot, and termites. To enhance cedar’s grain and colour it is most commonly stained, however it is possible to achieve a painted finish.


    Why choose Meranti?

    Meranti is of medium hardness, is easily handled and machined, and is very reasonably priced. It has a uniformly straight grain with few variations and is resistant to warping, cupping and twisting. Meranti readily accepts both stain and paint finishes. It’s widely used for decorative applications, including windows, doors, moulding and skirtings.

  • I have just received my delivery of timber windows and doors, how do I best finish them?
  • Product Finishing

  • My timber windows and doors, have visible water stains on the sill, is this a problem and how can I remove them?
  • Water stains on window sills and/or along the length of the stile, are signs that the original stain or paint has broken down, this is largely caused by inadequate product finishing

    To rectify, dry the timber and sand back the marked areas. Re-stain or paint the window or door in line with the instructions provided for finishing.

  • What are the black spots and/ or marks appearing on my timber windows and doors?
  • Black spots and marks are typically caused by:

    • Raw linseed oil
    • Excess residue after brick clean down. You may also see burn marks across any anodised components as a result of this clean down.
    • The use of steel wool as a sanding device, cutting of steel on site, or sand blown onto timber products, resulting in foreign particles embedding themselves into the products timber grain, causing the timber to discolour.

    Black marks can be removed with oxalic acid, please follow the manufacturers’ instructions and safety requirements. Black spots are not a fungi attack.

  • Are Botanica timber windows and doors manufactured using engineered timber?
  • Botanica doors and windows incorporate engineered components for superior structural integrity.

    All Botanica Meranti components are engineered. All Botanica Cedar jambs, heads and door stiles are engineered. Other Cedar components are made from solid timber.

  • I have old sliding doors and windows and that don’t slide smoothly. What can I do to fix them?
  • When sliding doors and windows no longer slide smoothly, it’s a sign that the products rollers are worn. This will occur over time due to product use. 

    To prolong the life of the rollers in your windows and doors, vacuum the sill regularly to remove dust, dirt and insects which cause a build-up of grit in the rollers.

    On an annual basis, clean tracks by wiping with light machine oil, such as sewing machine oil, to assist with smoother operation.

  • I have very old double hung windows do not slide up and down anymore, they also fall when I try to open them?
  • This is a sign that the windows spirals/balances need to be changed. When replaced it is recommended that you operate the window by moving the top and bottom sashes at least fortnightly.

    There are different spiral sizes that take different weights. The spiral should have a coloured mark on it to indicate its weight range. You will need to replace the old spiral with the corresponding colour and length.

  • How do I measure my windows and doors?
  • Our recommendation is that you get a licensed tradesperson to measure your windows and doors to ensure that all products fit correctly.

  • Why do my doors require a motif displayed across the glass? They look better without them.
  • According to AS1288-2006 Australian Standards Glass in Building any glazing that is capable of being mistaken for a doorway or opening must have a motif displayed on the glass.

    Motifs are required for the following:

    • A glass doorway, for example sliding door, bi-fold door, hinged door, must be fitted with Safety A glass or laminated glass
    • An opening between inside and outside of a building, for example a full glass fixed panel
    • Any glazing that can result in human impact, causing any type of bodily harm to a human being.
  • I have dry cement on my window frames and glass and would like to get it off without making any damage to the aluminium powdercoating or glass. Can you please help?

    There are different assessment tools used by Accredited Assessors depending on which state you are in.

    • National House Energy Rating Scheme (NaTHERS)
    • Nationally – AccuRate Sustainability by CSIRO
    • New South Wales – Basix
    • Queensland – BERS
    • Victoria – FirstRate

    For more information on the Building Code of Australia and these measures visit the Australian Building Code Board.

  • What are the new Building Code of Australia regulations in regard to Slips, trips and falls for windows?
