Reusing of windows
Reusing windows poses both technical and economic challenges, but the environmental benefits can be significant. By overcoming these challenges, the construction and real estate sector can contribute to a more sustainable future. One option may be to renovate the window in whole or in part. RISE offers quality assessment and action proposals.
Services
Inventory
A stock assessment involves evaluating and documenting the current condition and function of windows. Representative windows are selected to provide an overview of the entire stock.
Mold and Rot Investigation
A laboratory investigation in the microbiology lab involves taking samples from suspected areas and analyzing them to identify the presence of mold and rot. This may include microscopy and other techniques to determine the type and extent of the damage.
Chemical contamination, e.g. PCBs
Sealants and other building materials may contain chemicals such as PCBs (polychlorinated biphenyls). A chemical content investigation involves taking samples and analyzing them to determine the presence and concentration of these substances
Rain and Airtightness
Determining rain and air tightness involves testing the ability of windows to resist water ingress and air leakage.
Status determination of insulating glass
Assessment of the residual function of insulating glass involves evaluating the insulating ability of the glass and any damage or deterioration. This can include measuring the U-value and inspecting the tightness and condition of the glass. Testing the gas filling level. Investigation of the consumption of the desiccant contained in the spacer strips.
Thermal transmittance coefficient U-value
Determining the current U-value means measuring how well a window insulates heat and cold. A lower U-value indicates better insulation and reduced heat loss
Acoustic properties
If there are requirements for acoustic properties, this means evaluating the windows' ability to attenuate sound and reduce noise.
Proposed measures
Based on the above investigations and assessments, proposals for measures are prepared to improve the condition and function of the building's windows. This may include repairs, replacement of materials and other improvement measures.
Methods
RISE probably has Sweden's largest accreditation from Swedac regarding window testing.
Reporting
A completed assignment is usually reported in a written report.
