If you are looking for expert knowledge about double glazing old wooden windows and frames in your character home, then we have the answers. Our team offers quality double glazing installation for homes in the Wairarapa and Manawatu using the world-class Thermawood system for timber windows. Contact us to arrange a consultation and quote for the cost of retrofit double glazing.
In 99% of cases, yes! One of Thermawood Wairarapa's Authorised Installers will visit you and make an initial assessment of your windows, to make sure they're suitable to be retrofitted. You'll be provided with a copy of the written assessment. We can retrofit casement, double hung and fixed windows.
Wherever possible, we will retrofit your windows onsite. No matter the weather, no one wants boarded-over windows if it can be helped! We remove the windows, rebate the frames using our purpose-designed tooling, install Thermawood Retrofit hardware and re-fit the windows the same day. Two Thermawood installers can retrofit around 6 panels per day. Take the total number of windows to be double glazed and divide by 8 to get an indication of how long your home will take.
No, we generally do not involve ourselves in the painting of your windows. Most customers like to paint their own windows, or have their own preferred qualified painter. We stick to what we're good at - the best retrofit double glazing for your home - but we do leave the window ready to be painted with all pin holes etc filled.
Yes. We weight the sash with double glazing installed and re-weight the double hungs accordingly so that they still operate properly.
Double glazing will help reduce condensation. If your glass gets cold enough, moisture will still condense on your window's interior; however double glazing helps retain the heat in your home reducing the likelihood that condensation will form.
Yes. Standard double glazing will make your home quieter by around 25%; if noise is a particular problem, different glass types can be used in the double glazing unit to boost noise reduction to approximately 55%.
Yes, Thermawood has been tested to and passed building standard NZS4211:2008, the industry standard for weather-tightness of windows and doors.
We complete an assessment of your windows when we provide you with your quote, but sometimes rot isn't visible until we rebate the window frame and we can't predict or price for this. If this happens, we can arrange to have a new sash made and installed alongside the rest of the job for a very competitive price. This is generally the only thing that would change our quoted price after you accept it.
Of course! We can price per window or room if this suits you, allowing you to approach your project gradually and manage the costs. We have many customers that remain on our schedule for 2-3 years, retrofitting their home room by room as they are able to afford it.
Yes, we can install seals into all opening windows, making them more efficient. We generally price this service separately.
Yes, we can preserve your leadlight windows. The Thermawood system removes the glass from the frame, which protects the leadlights. We trim the edge of the leadlight, install a new border lead (as it is usually damaged from the window putty), reseal the leadlight and install it into the double glazing unit where it will be protected from the elements.
As long as you heat or cool your house, double glazing will retain that heat or cold. The Thermawood system works equally well keeping in heat or cold, making it a year-round solution for energy savings.
The Thermawood Grandadapter is made in New Zealand from recycled milk bottles, and all timber beading is made from sustainable sources. We're committed to making the Thermawood system a very green, environmentally responsible product.
