The Refurbishment Process: A Step-by-Step Overview

Comparison: Refurbishment vs. Replacement

When deciding between reconditioning initial windows or setting up contemporary replacements, several factors enter play, consisting of expense, longevity, and visual impact.

Enhancing Thermal Performance

Among the primary grievances concerning initial sash windows is their bad thermal insulation. Historically, these windows featured single-pane glass, which provides minimal resistance to heat loss. During the refurbishment procedure, there are 2 main methods to address this:

1. Advanced Draught-Proofing

By installing a detailed draught-sealing system, air leakage can be minimized by approximately 80%. This not only keeps the property warmer but also significantly minimizes external noise and prevents dust and pollen from entering the home.

2. Slim-Profile Double Glazing

In some cases, the initial sashes can be modified to accommodate "Slimlite" or vacuum-sealed double-glazing systems. These units are thin adequate to suit the original glazing bars, providing the thermal benefits of modern windows without the bulky look.

Expense Factors in Refurbishment Projects
