Don’t Fall Into the Trap Of Double Glazing Cowboys! Most don’t offer warranties on their products!
When considering double glazing for your wooden windows, beware of industry cowboys and inferior products and services.
Here’s Why
The Moisture Trap
The Common Installation Mistake
Often, window installers place the double glazed unit into a square rebate and seal it with a commonly used silicone sealant. Initially, this seems to work, and your timber joinery appears safe. However, over time, problems arise as water becomes trapped.
The Slow Deterioration
Because the double glazed unit is sitting in a square rebate, it becomes vulnerable to moisture pooling in the rebate. Water vapour then begins rotting the timber and saturating the seal. The moisture pulls contaminants out of the silicone sealant, resulting in water concentrated with dirt and contaminants. This slowly deteriorates the polysulphide seal/silicon seal of the double glazed unit. Once the seal is damaged, moisture and air enter the unit, leading to that misty look inside the glass.
Poor Installation Practices
No Drainage Track
Without a drainage track, the system will leak, units will break down, and frames will rot.
Unmodified Rebates
Rebates need to be modified to provide enough room for the thickness of the unit and prevent moisture accumulation.
Weight Issues
If ropes aren’t reinstalled and weight issues resolved, windows won’t open and are often screwed shut.
Hardware and Sash Issues
The hardware has not been replaced, and the top sash is secured in position with timber blocks under the horns.
No Draught Sealing System
Without proper draught sealing, you wont reduce the noise, cold draughts will get into your home and your windows will not perform efficiently.
The Risks
These poor installation practices lead to significant problems over time, including rotting timber, failing double glazed units, and compromised window functionality. To avoid these pitfalls, choose a reputable company with experienced installers who use high-quality materials and proper techniques.
This often leads to the job needing done twice costing the homeowner a lot more in the long run.

Rebate With A 15-Degree Slope

Unique Dry Glazing System
Compliance and High Standards
Why This Is Important.
AS4666 (Insulating Glass Units)
This standard ensures that all double-glazed units (IGUs) are designed to last, with strict requirements for durability, thermal insulation, and moisture resistance.
Superior Insulation: Keeps your home warmer in winter and cooler in summer, lowering your energy bills.
Condensation-Free Glass: Properly sealed IGUs prevent condensation buildup between panes, ensuring clear, fog-free windows.
Long-Lasting Performance: Our compliant installations maintain their efficiency for years, protecting your investment.
AS1288 (Glass Installation)
This standard ensures that glass is installed correctly to withstand wind loads, prevent breakages, and ensure structural safety.
Enhanced Safety: Proper installation makes glass more resistant to breakage, protecting your home and family.
Reliability in Harsh Weather: Our installations are built to endure extreme weather, minimizing the risk of failures.
Extended Warranties: Compliance guarantees that your installation is fully covered, unlike non-compliant suppliers who risk voiding warranties.
Why Compliance Matters
Other suppliers and DIY solutions cut corners by ignoring these critical standards to save costs. For instance, Most use square rebates without proper drainage, which is non-compliant with AS4666.
The result?
Costly repairs and reduced window lifespan.
By adhering strictly to AS4666 and AS1288, Thermawood ensures:
Long-Term Peace of Mind: We back our work with a 10-year warranty that covers both workmanship and materials, providing security that DIY solutions simply can’t match.
