How Draught Proofing Enhances Window Performance
RHP Renovations Ltd improve sash window efficiency by installing draught-proofing systems designed to minimise air infiltration while preserving the original appearance. Brush strips are carefully routed into timber frames, sealing gaps without affecting operation or ventilation. Sashes are fitted with appropriate gauge draught pile along rails to ensure airtightness. Let us maintain fresh air circulation while preventing cold air from entering, reducing heat loss and creating a more comfortable living environment.

Flexible Draught Proofing For Various Gap Sizes
Gaps in old sash windows can vary from 3mm to 10mm. Our draught-proofing system comes in multiple lengths, including 5.5 mm, 8.5 mm, and 11.5 mm, ensuring precise sealing for each window. By custom-fitting the draught pile, we maintain smooth operation and adequate airflow while eliminating cold drafts. Let us address every window individually, providing insulation that improves energy efficiency, reduces heating bills, and enhances comfort in period properties or conservation areas.
Detecting Air Leaks With Thermal Imaging
RHP Renovations Ltd uses thermal imaging to locate air infiltration and heat loss in ageing sash windows, supporting sash window repairs and restoration and double glazing for sash windows as part of a complete efficiency upgrade. This survey identifies gaps and misalignments that reduce performance. Based on the results, we fit the correct gauge draught pile and ensure all windows are sealed correctly. After installation, windows are retested to confirm airtightness and thermal performance while maintaining the property’s period character.

Energy Savings And Comfort Benefits Of Draught Proofing
Draught-proofing sash windows prevents warm air from escaping and cold air from entering, ensuring a consistent indoor temperature. This reduces heating costs and contributes to noticeable energy savings. The added insulation also provides noise reduction, enhancing overall comfort. Let us deliver a system that protects energy and value, preserving the appearance of period windows while addressing the common issue of sash window rattles and inefficient airflow beneath radiators.
