A leading sash window remediation company does not simply utilize 19th-century techniques; they incorporate modern product science to improve the window's efficiency.
Accoya ® Timber: A chemically modified wood that is essentially rot-proof and exceptionally steady, suggesting it won't swell or shrink with the seasons.Epoxy Resins: Advanced bonding agents that can stabilize old lumber and supply an irreversible repair that is more powerful than the wood itself.Vacuum Glazing: An ultra-thin glazing alternative (as thin as 6mm) that uses the thermal performance of triple glazing while fitting into the initial thin refunds of 18th-century sashes.Frequently Asked Questions (FAQ)1. Can rotten sash windows truly be saved?
In the large bulk of cases, yes. Even when timber appears seriously decayed, a professional can normally change the rotten areas (such as the sills or bottom rails) while keeping the original frame and upper sashes undamaged.
2. Is double glazing possible in initial sash windows?
Yes. Modern "slimlite" double-glazed systems are developed to fit into the initial timber profiles. This provides the benefits of contemporary insulation without the bulky look of basic double glazing.
3. Will repair assist with outside sound?
Considerably. A lot of sound gets in through gaps around the window. A professional draught-proofing system seals these gaps. Moreover, updating to thicker or acoustic glass throughout the restoration process can even more reduce decibel levels.
4. For how long does the remediation procedure take?
Usually, a single window can be fully brought back and draught-proofed within one to 2 days, though larger projects involving multiple windows or substantial rot might take longer.
5. Do I require preparing approval?
If you live in a Grade I or Grade II listed structure, you will likely require Listed Building Consent for any changes, including double glazing. However, basic repair work and draught-proofing frequently fall under "like-for-like" upkeep. If you are in a Conservation Area, it is constantly best to check with the regional authority.
