How Window Replacement for Traditional Properties Can Reduce Repainting Costs
Traditionally, sash windows were painted with oil-based paints that are non-gas permeable. Due to variations in surface temperature—ranging from as low as -10°C in winter to over 60°C in direct sunlight—the moisture content within the timber can create internal gas pressure. With no way to escape, this pressure leads to the formation of paint blisters, which eventually burst and allow water to seep behind the paint layer. This accelerates deterioration and necessitates frequent maintenance, typically requiring scraping, sanding, undercoating, and repainting every 2-3 years.
In contrast, modern timber windows can be treated with a gas-permeable penetrating preservative base coat followed by two coats of spray-applied microporous paint. This creates a high-quality, furniture-grade finish that functions similarly to a GORE-TEX jacket—allowing moisture in its gaseous form to escape from the inside out, while preventing liquid water from penetrating from the outside. This makes it an ideal choice when considering window replacement for traditional properties. As a result, microporous paint does not blister or crack, significantly extending the effective lifespan of the paint and the period between repainting.

Additionally, repainting microporous-coated windows requires significantly less preparation than traditional gloss oil-based paints. There is generally no need for extensive scraping, sanding, or undercoating, reducing both the labour and cost associated with upkeep. Furthermore, as microporous paint is water-based, any excess on the glass can be easily wiped off with a damp cloth, to achieve a clean, precise finish.


How does Window Advice Centre help reduce long-term maintenance costs?
We advise and assist Clients to source modern window solutions with advanced microporous coatings, for a durable, low-maintenance finish that enhances longevity while preserving the traditional aesthetic of your property.
Performance Benefits of New Timber Sash Replacement Windows for Traditional Properties
Accurately manufactured new timber vertically sliding sash windows, built to precise dimensional tolerances, allow for the effective function of multiple draught-proofing measures. These include compression seals, interlocks at the meeting rails, and multi-line draught strips, all of which contribute to reducing heat loss and improving energy efficiency.
Properly designed window frames will have dimensions that accommodate deep glazing rebates, so that the spacer bars and butyl sealant at the four edges of energy-efficient double-glazed units are fully enclosed. This design results in a seamless aesthetic where only the glass is visible, avoiding the intrusion of spacer bars into the glazing area. These design enhancements significantly improve window replacement for traditional properties, offering long-term performance benefits.
Additionally, well-engineered timber sashes feature glazing rebates of sufficient depth to house double-glazed units with optimal air gaps, significantly enhancing thermal performance. This can result in up to an 80% reduction in heat loss compared to single glazing, making traditional properties far more energy-efficient while maintaining their historic charm.

What performance improvements can clients expect from Window Advice Centre’s recommended solutions?
